Airport Connectors
The most interesting transit planner in the world:
This principle is true primarily for large international airports. As I will explain, this is less true of smaller airports. But before going on, I would like to clarify a distinction between bad and overrated. Airport connectors, as I have argued many times, are overrated: city elites tend to like them disproportionately to their transit usage, as do many urban boosters, who think a comfortable airport connector is a necessary feature of a great global city. The result of this thinking (and also the main evidence we have that this thinking exists) is that airport connectors are built at much higher costs per rider than other transit projects: the JFK and Newark AirTrains cost more than $100,000 per weekday rider, much more than other recent rail projects in New York; even the far over-budget East Side Access, at current estimates, is about $60,000.
However, overrated does not mean bad. There exist airport connector projects with reasonable cost per rider. They’re still overrated, which means they’ll be built concurrently with even more cost-effective non-airport projects, but they’re good enough by themselves. As an example, take the Canada Line. The total cost was about $2 billion, and the latest ridership figure I have, from 2011, is 136,000 per weekday, ahead of projections. At $15,000 per rider, this is reasonable by European standards and very good by North American ones. Let us now look at the two branches of the line, to Richmond and the airport. Lacking separate cost data for them, I am going to estimate them at about $300 million each, as they are entirely above-ground; the airport branch is 4 km and the Richmond branch is 3 km, but the Richmond branch has an urban el and the airport branch doesn’t. For ridership data, we have this set of figures per station (which results in a Canada Line total of only 113,000). Boardings and alightings sum to 19,000 on the airport branch and 34,000 on the Richmond branch; we’re double counting intra-branch trips, but there presumably are very few of these. As we see, the Richmond branch is more cost-effective, but the airport branch holds its own – since the per-station data has a lower overall Canada Line ridership, the airport branch’s presumed cost per extra rider generated is less than that of the entire line! (This sometimes happens, even with branches that generate less ridership than the trunk.) Clearly, despite the fact that airport connectors are overrated, this is an example of a good project.
The importance of the overrated vs. bad distinction is then that good transit advocates need to be wary, since airport connectors that don’t work well might get funded anyway, ahead of more deserving projects. But there remain good airport connectors, and therefore we should discuss what features they might have. The answer given by city elites is typically “nonstop connection to the CBD,” often with a premium fare. But the good transit answer is more complicated, and the graphic at the top of the post is only a partial answer.
There is a difference between short- and long-distance air travel. In many cities it doesn’t matter much because there’s a single dominant airport – Beijing, Frankfurt, Zurich, Atlanta, Toronto – but in others there are multiple airports, with different roles. Often there will be a smaller, closer-in, older airport, serving mostly domestic flights, and a larger, farther away, newer international airport. Paris has Orly and Charles-de-Gaulle, Chicago has Midway and O’Hare, New York has LaGuardia and JFK (Newark is intermediate in its role, even if it’s the oldest), Los Angeles has Burbank and LAX (the other airports are somewhat outside this division), Dallas has Love Field and DFW, Tokyo has Haneda and Narita, Seoul has Gimpo and Incheon. Because those airports have different functions, they require different kinds of transportation links.
First, let us consider departing passengers. If they travel to another continent, their options are quite restricted: for example, if they live within driving distance of Atlanta, they’re flying out of Atlanta. Even if there are closer secondary airports (such as Greenville-Spartanburg and Chattanooga), they don’t offer such service – at most, they offer a connecting puddle jumper flight to the primary airport. In contrast, if they travel shorter distances, and live far from the primary airport, they could fly out of a secondary airport, or might just drive instead of flying: a 2-hour drive to the airport is comparatively more tolerable for an 8-hour intercontinental flight than for a 1.5-hour short-hop flight. For example, when I lived in Providence, my air trips were all to the West Coast or Europe, so I flew out of Boston or even New York; but when my sister visited, she chained trips and also visited her boyfriend, who at the time lived in North Carolina, and for the domestic leg of the trip she flew out of T. F. Green.
The result is that primary international airports draw their departing passengers from a much wider shed than mainly domestic airports. In metro areas with such separation of airports, the international airports – Charles de Gaulle, JFK, DFW, Incheon, etc. – draw riders from faraway suburbs and even from adjacent small metro areas, whereas the domestic airports draw riders primarily from the city and its nearby suburbs.
Now, let us consider arriving passengers. Destinations are more centralized than origins, but this is especially true for international trips than for domestic ones. Tourism trips are heavily centralized around a few attractions, which in most cities are in the CBD, or in specific locations: if you’re flying to the Paris region for tourism, your destination is either Paris proper or Eurodisney, rather than an average suburb. Business trips are also heavily centralized around the CBD and a few edge cities. Personal visits have no such concentration, and these are much more common for short-distance domestic flights than for long-distance international flights. I am unusual in that I live on a different continent from my parents; usually, people live within ground transportation or short-distance flying distance from family and friends, depending on the country they live in (short-distance flying distance is more common in the US). The result here is that arriving passengers at domestic airports are typically interested in visiting the CBD but often also the rest of the metro area, whereas arriving passengers at international airports are much more CBD- or tourist attraction-centric.
Some evidence for this difference can be found in looking at the Consumer Airfare Report, which has domestic O&D traffic counts between airport pairs. The primary international airport usually has a smaller percentage of its domestic O&D traffic going to shorter-distance cities. For example, at LAX, 13% of traffic is within California, and another 6% is to Las Vegas, Phoenix, and Tucson, within a 3-hour high-speed rail range. At Burbank, the corresponding figures are 42% and 21% respectively. The same pattern can be observed for O’Hare (8.6% of traffic is internal to the Midwest) and Midway (14.6%), and DFW (3% of traffic is internal to the Texas Triangle) and Love Field (27%).
The mode of transportation that best suits the needs of international airports is then mainline rail. On the one hand, it tends to be better than urban transit at serving trips that are dedicated to CBD service, since commuter rail is more radial than urban transit, and the stop spacing is typically also longer (although dedicated premium connectors are still often wastes of money). On the other hand, it can extend deep into the suburbs and to adjacent metro areas, and expand the airport’s draw. People can ride intercity (often high-speed) trains direct to the terminal at Frankfurt, Zurich, and Charles-de-Gaulle, and this allows those airports to be the primary international airports for metro areas in a wide radius: SNCF code-shares with airlines to connect people from Charles-de-Gaulle to Lyon, 400 km and 2 hours away by TGV.
This is not true of small domestic airports. A TGV connection to Orly would’ve been much less beneficial than the current connection to Charles-de-Gaulle: most of Orly’s traffic is short-distance, often competing with the TGV rather than complementing it.
With this distinction in mind, we should look at the situation at the major American airports. In California, the current plan is to have California High-Speed Rail serve both SFO (at Millbrae) and Burbank Airport; the original plan served Downtown Burbank instead of the airport, but the HSR Authority seems to have shifted its focus, and wants Burbank to be the southern terminus of the line, pending construction to LA Union Station. This is bad planning. Nearly two-thirds of Burbank’s traffic competes either with California HSR or with future tie-ins. People from Bakersfield and Fresno are unlikely to take a train to the airport to connect to a flight, since they can take a train the whole way, or drive directly to Las Vegas or Phoenix. People in Bakersfield and Fresno would be more interested in a connection to LAX, whose traffic complements rather than competes with intercity rail.
Los Angeles could build a connection to LAX, running both frequent electric commuter trains and high-speed trains on it. The Harbor Subdivision has existing tracks from Union Station almost the entire way to the airport, although the route is at-grade, with a large portion of it running next to Slauson Avenue, and most likely a major project like this would require viaducts. Only a short greenfield segment, elevated over Century, is required to reach the proposed Terminal 0 location, and that is only necessary if, as in Zurich and Frankfurt, LAX wishes to avoid a landside people mover. It is both bad transit and bad politics to build this only for nonstop trains: the route passes through reasonably dense urban neighborhoods, and should have 10-12 stops along the way, with some trains running local and others making only 1-3 stops, at major nodes such as Inglewood or the intersection with the Blue Line. There is room for passing sidings at the line’s midpoint, but the low top speed and the short length of the line is such that overtakes are only necessary if there are nonstop and local trains every 10 minutes. Such an airport connector would serve many different trips at once: HSR trips from Central Valley cities to LAX, arriving trips from LAX to Downtown LA (and, via transfers at intermediate stops, to the Westside), and local trips on the Slauson corridor. It’s a flexibility that modernized regional rail has, and that other modes of transportation, which can’t mix local and intercity traffic as well, lack.
Leaving California, let us look at New York. There are perennial proposals for a new connection to LaGuardia (via an extension of the N) and an additional connection to JFK (usually using the Rockaway Cutoff). There is also a new proposal for a Newark connection via PATH. With the distinction between short-distance domestic and long-distance international airports (Newark is intermediate between the two), we can analyze these proposals. Newark is the easiest to dispose of: the cost is extreme, $1.5 billion for 4 km above ground. It also has several design flaws: unlike the LAX connector I outlined above, this proposal is nonstop from Newark Penn, skipping the former South Street railroad station; the lack of intercity service improvement and the poor service to the Midtown hotel clusters doom it as a CBD connector.
The JFK proposals are problematic as well. The AirTrain connection to Jamaica is quite useful, since it lets people from all over Long Island connect to the airport. Improving JFK access hinges on improving service to Jamaica, then: through-service from New Jersey, higher off-peak LIRR frequencies, reelectrification with catenary to permit Amtrak send Northeast Corridor trains that aren’t needed for Boston service to Jamaica. East Side Access improves JFK access as well, since it allows LIRR trains to serve Grand Central, which is closer to the Midtown hotel clusters than Penn Station. Ideally there wouldn’t be an AirTrain connection, but it’s the best that can be done given existing infrastructure and given Jamaica’s importance. A Rockaway Cutoff connection, which branches from the LIRR Main Line west of Jamaica, would not help Long Islanders go to JFK; it would also not be able to carry intercity trains, since Amtrak trains to Jamaica can serve both airport riders and Long Island riders, each of which groups alone is too small to justify intercity trains on its own.
In contrast, LaGuardia proposals are better, since for a close-in, domestic airport, service to the entire city is more important. I remain somewhat skeptical – airport connectors are still overrated – but less dismissive than of Newark and JFK proposals. LaGuardia travelers from the Upper East Side, which as far as I remember supplies a majority of its departing traffic, would have to transfer at 59th Street; but they have to detour through 59th or 125th via taxi already, and the subway would not get stuck in Manhattan traffic. Conversely, there is much less need to connect the airport with the suburbs and with neighboring metro areas than there is with JFK, which means that there is no point in constructing people movers to the LIRR.
Finally, let us look at Chicago. O’Hare has the airport connection of a domestic airport rather than that of an international airport. There are plans for an express link to the Loop, but these do nothing for departing passengers from neighboring areas. While airport connectors tend to be overrated, express premium-fare links are especially overrated, since they give business travelers dedicated trains, on which they always find seats, without needing to commingle with lower-income riders.
However, some of the Midwestern high-speed rail proposals include a connection to O’Hare from the outlying metro areas, and this is good planning, assuming the cost is not excessive. SNCF’s proposal includes a bypass of Chicago that serves O’Hare, similar to the Interconnexion Est. A second step, if such a connection is built, is to attempt to connect regional lines to it, if they are electrified. This includes both inward connections, i.e. a frequent commuter rail connection to the Loop or West Loop with good connections (ideally, through-service) to other commuter lines, and outward connections, i.e. low-speed short-distance intercity lines, such as to Rockford.
In all of these cases, the common thread is that the connection to the airport does not need to be a premium service, marketed only to the business traveler. These services are never the majority of airport transit ridership: see Hong Kong, Tokyo, and London numbers on PDF-p. 28 here. However, it does need to provide service to both departing and arriving passengers, and for a major international airport, this requires good service to the suburbs and to adjoining metro areas. The optimal technologies are often bundled together with premium fares – high-speed rail is in many countries, mainline rail is in North America – but the benefits come from features of the technology and service pattern, rather than of the branding. Good transit projects connecting to airports will make sure to have the correct service reach, while at the same time not excluding local riders.
Suburban Geography and Transit Modes
A post on Let’s Go LA from last year, about different suburban development patterns in different regions of the US, praises Los Angeles’s suburbs for having an arterial grid that allows some density and permits frequent bus service. The Northeast, in contrast, has a hierarchical system, of town centers surrounded by fractured streets and cul-de-sacs, at much lower density. This is how Los Angeles’s urban area has the highest standard density in the US, and one of the highest weighted densities, nearly tying San Francisco for second place after New York. It sounds like a point in favor of Los Angeles, but missing from the post is an analysis of how Rust Belt suburban development patterns reinforce prewar transit. Briefly, Western US grids are ideal for arterial buses, Northeastern town centers are ideal for commuter rail, which used to serve every town.
For a Northeastern example, the post brings up Attleboro as a historic town center. Look at the image and notice the walkable grid and development near the train station, although one quadrant of the station radius is taken up by parking. Attleboro is in fact the town with the oldest development on the Northeast Corridor between Boston and the Providence conurbation, and the only one that, when taking the train between Boston and Providence, I’d be able to see development in from the train. Sharon and Mansfield, both developed decades later, do not have as strong town centers. But conversely, many town centers similar to Attleboro’s exist in the Northeast: Framingham, Norwalk, Tarrytown/Sleepy Hollow, Huntington, Morristown, Paoli.
Now, a careful look at the specific examples of Norwalk and Huntington will show that the most walkable development is not necessarily at the train station. In both suburbs, the old town center is where the original road goes – Northern Boulevard and its eastern extensions in Long Island, the Boston Post Road in Connecticut. Huntington has a second center around the LIRR station; Norwalk has a much smaller second center around the South Norwalk Metro-North station. For the most part, the railroads went close enough to the older roads that the town center is the same, as is the case especially in Attleboro, Tarrytown, and Paoli, and in those cases, commuter rail can at least in principle serve jobs at the suburban town center.
This boils down to the difference between optimal bus and rail networks. Buses love grids: they typically serve the scale of a single city and its inner suburbs, and there it’s feasible to provide everywhere-to-everywhere service, which grids are optimal for. For the suburbs, this breaks down. Buses on uncongested arterial roads are still surface transit; an average speed of 30 km/h is aspirational, and that is for suburbs, not dense urban neighborhoods. On a road where the bus can average 30, cars can average 50, and cars can also use expressways without splitting frequency between different suburban destinations, speeding their journeys up greatly. Meanwhile, commuter rail can, depending on stop spacing, average 50-60 km/h easily, and an aggressive timetable can cross 80 if the stop spacing is relatively express.
There is no such thing as a rapid transit grid. Subway networks almost invariably look like a central mesh, often containing a circumferential line, with spokes radiating out of it in all directions. Mexico City has a larger mesh, approximating a subway grid, but its outer ends again look hub-and-spoke. Counting commuter rail, the hub-and-spoke system is as far as I can tell universal, with the exception of highly polycentric metro areas like the Ruhr. The spokes are rarely clean: they often cross each other (see for example the London Underground to scale). But looking at a city’s rail transit map, you’ll almost always be able to tell where the CBD is, where the inner-urban neighborhoods are, and where the outer-urban and suburban areas are.
At this distance, then, having a bus-friendly grid doesn’t matter much. What matters is having a good network of historical rights-of-way that can be used for regional rail, and a preexisting pattern of development following these lines and their junctions. In the US, the older cities have this, whereas the newer ones do not. In a suburb like Attleboro, good transit means good regional rail, with high all-day frequency, and a network of feeder buses timed to meet the trains. Grids aren’t especially useful for that.
And this is why, despite being so dense, Los Angeles has so little transit usage. Its street network is set up for bare-bones public transit, usable by people who can commute two hours in each direction and will never get cars. Because it was a medium-size city when its car ownership exploded, it doesn’t have as many town centers; its density is uniform. It has a higher weighted density than the Rust Belt outside New York, but its weighted-to-standard density ratio is much lower than those of Philadelphia, Boston, and Chicago. (It barely trails Washington, which has fewer town-center suburbs than the Rust Belt, but made an effort to actually build them around Metro; its Tarrytowns have Metro service rather than infrequent commuter rail.)
The optimal urban geography for urban transit is not the same as that for suburban transit, and the optimal street network for surface transit is not the same as that for rapid transit. Los Angeles could potentially excel at surface urban transit, but there’s only so much surface transit can provide the backbone of public transportation in a city. It has a handful of strong lines for rapid transit, and that’s a serious problem, which a grid won’t really solve.
Underrated Transit Projects
In between the airport connectors and mixed-traffic streetcars are some public transit proposals that would be potentially high-performing. This is a list of potential lines in the US that don’t get nearly the exposure that they deserve.
The basic rule of this post is that if it’s being built, or is on an official urban wishlist pending finding the budget for it, then it’s not underrated. Some of the most important transit projects in North America are in this category: Second Avenue Subway’s current and future phases, the Regional Connector, the UBC SkyTrain extension. What I’m interested in is lines that are only vaguely on any official wishlist, if at all, but could still get very high ridership compared to their length. It is possible that these underrated lines would turn out to be worse-performing if a study were undertaken and the costs turned out to be very high, but in no case was there an honest study. Sometimes there has been no recent study; other times there is one but it sandbags the project.
Finally, I am not including commuter rail projects on this list. Under current regulations and operating practices, nearly all North American commuter rail projects are wastes of money. Conversely, nearly all projects that assume modernization of practices are underrated. This swing, based almost entirely on organizational question, is why I’m excluding these projects from this list. The subway and light rail projects below are less sensitive to organizational questions.
Utica Avenue Subway
Location: New York
Concept: an extension of the 4 from Crown Heights along Utica Avenue to Kings Plaza, about 7 km. If Second Avenue Subway’s Phases 3 and 4 are built, then a branch can be built from Second Avenue to Williamsburg and thence under Bushwick, Malcolm X, and Utica, taking over the entirety of the line, with the 4 cut back to its current terminus; this is an additional 9 km to Second and Houston.
Why it’s underrated: the second busiest bus route in New York, the B46, follows Utica: see here for New York bus route rankings. The busiest follows First and Second, which are getting a subway. Two additional routes in the top ten, the B44 and the B41, follow Nostrand and Flatbush respectively, fairly close to Utica. The B46 has 48,000 weekday riders and the B41 and B44 have another 70,000 between them. Since subways are much faster than city buses, the expected ridership is much higher than 120,000, measured in multiples rather than in a percentage increase. In addition, the 2, 3, 4, and 5 are all busier coming to the Manhattan core from Uptown than from Brooklyn, so adding to their ridership from the Brooklyn end balances the loads better, and avoids the required increase in operating costs for the new riders.
What is being done right now: nothing.
Geary Subway
Location: San Francisco
Concept: a full subway from Market Street to the Outer Richmond District, about 9 km. This can connect to the BART subway, the Muni Metro tunnel, or a second Transbay Tube if one is built.
Why it’s underrated: the 38-Geary is the busiest bus route in San Francisco, with 57,000 weekday riders between the local, the limited, and the express buses: see here for San Francisco bus ridership. Parallel corridors are also busy: the 1-California has 29,000, the 31-Balboa has 10,000, and the 5-Fulton has 17,000. Some of the census tracts along the middle of the route, in Little Osaka Japantown, rank together with Los Angeles’s Koreatown as the densest in the US outside New York. BART’s current limiting factor is not the Transbay Tube, but the grades farther south in San Francisco, which lengthen the braking distance and make it impossible to run a full 30 trains per hour through the core segments; a Geary branch leaving south of Montgomery Street would reduce service to points farther south, but improve capacity for riders heading from Oakland to the San Francisco CBD.
What is being done right now: there were never subway plans, but there were light rail plans, which due to local merchants’ opposition to loss of space for cars were downgraded to a rapid bus. The city’s FAQ on the subject even has the cheek to portray the Boston Silver Line and the Los Angeles Orange Line as successes.
Downtown Relief Line
Location: Toronto
Concept: there are several different alignments, but all feature an east-west line somewhere between Queen Street and Union Station, with one or two bends to the north to intersect the Bloor-Danforth Line. The latter two alignments (using option 4B for the second one) feature about 12 km of tunnel; I do not know how much the first one has.
Why it’s underrated: only one subway line serves Downtown Toronto, the Yonge-University-Spadina Line. Bloor-Danforth is too far from the CBD, and requires a transfer. The transfer points are very crowded: as far as I can tell from this list, the central one, Bloor-Yonge, has 200,000 weekday boardings, apparently including transfers. Without figures that include transfers in other cities I can’t make comparisons, but I doubt any two-line, four-track station in New York has this many riders. Union Station is quite crowded as well, and DRL proposals include transfers to outlying commuter rail stations. Ridership on parallel streetcars is very high: there are 53,000 on King Street, 44,000 on Queen, and, if a more northern alignment for the DRL is chosen, 32,000 on Dundas.
What is being done right now: more studies; construction will almost certainly begin any decade now. Neither David Miller’s Transit City light rail proposal nor Rob Ford’s replacement of Transit City with subways included the DRL.
125th Street Subway
Location: New York
Concept: either Phase 5 or Phase 2.5 of Second Avenue Subway, going west along 125th to Broadway, with a station at each intersection with an existing north-south subway.
Why it’s underrated: east-west transportation in Manhattan is slow, even by the standards of Manhattan buses. The 125th Street buses in my experience are slower than walking; despite this, the various routes have about 90,000 weekday boardings between them, of which about 30,000 come from 125th Street itself. Second Avenue Subway Phase 1 is going to substantially improve east-west transportation, by serving Times Square and offering a two-seat ride from the Upper East Side to the Upper West Side and Central and West Harlem; however, passengers from East Harlem will still have to take a major detour to avoid the crosstown buses. While SAS offers a relief to the 4/5 and 6 lines, the 2/3 and A/D express lines are overcrowded as well, and a connection at 125th Street would divert some East Side-bound commuters.
What is being done right now: nothing, although (some) railfans who work at the MTA privately want to see such a line built.
Silver Line Light Rail
Location: Boston
Concept: replacement of the Silver Line buses along Washington Street with light rail, feeding into an existing Green Line portal, about 4 km of light rail.
Why it’s underrated: the Silver Line buses are the busiest in Boston, with 15,000 weekday riders on the buses to Dudley Square: see PDF-pp. 47-48 of the MBTA Blue Book. The ridership doesn’t justify a subway, but does justify dedicated lanes and rail. The Green Line tunnel has some spare capacity, has a portal pointing in the correct direction, and could take an additional train every 6 or 7 minutes, which would give riders in Roxbury faster trips through Downtown Boston.
What is being done right now: nothing – a study sandbagged the rail bias factor and assumed only 130 new transit riders on a Silver Line light rail service, making the project appear cost-ineffective.
Triboro RX
Location: New York
Concept: a circumferential subway line, with about 1 km of new tunnel and 35 km of route on preexisting rights-of-way, abandoned or lightly used by freight trains today.
Why it’s underrated: the biggest cost driver, right-of-way formation, is already present. The right-of-way in question has a few daily freight trains, but the most critical link, the Hell Gate Bridge, is four-tracked, and freight trains can be kicked out from their segment of the bridge and moved to the Amtrak tracks. The work done by Michael Frumin and Jeff Zupan in the late 1990s estimated about 150,000 commute trips per weekday (76,000 commuters each making a roundtrip per day), which is low for a greenfield line of this length but reasonable for a line on existing rights-of-way.
What is being done right now: nothing, although ever since Lee Sander mentioned the line in 2008, politicians have paid lip service to the concept, without committing funding.
Boston Circumferential Line
Location: Boston
Concept: a circumferential subway, from Harvard Square to Dudley Square or the JFK-UMass subway stop, roughly following the 66 bus route where it runs and intersecting the busiest stops of the Green Line branches and some commuter rail stops. This is about 12 km.
Why it’s underrated: although the busiest Boston bus is the Silver Line to Dudley Square, the next few are circumferential, particularly the 1 and 66, and secondarily the 23 and 28; together this is about 50,000 riders. Boston’s street network is hostile to surface transit except on a few major streets such as Washington, which is why there is no hope of making such a line light rail, which would fit the projected ridership better. A route that parallels the 66, at least until it hits the E branch of the Green Line, would intersect the B, C, and D branches at their busiest respective surface stops, and improve connectivity to Cambridge, which is increasingly a major business district of the Boston region in its own right.
What is being done right now: BRT, on convoluted alignments that don’t exactly follow either the 66 or the 1 where they are parallel but instead make detours.
Nostrand Avenue Subway
Location: New York
Concept: an extension of the 2/5 from Flatbush to the southern end of Nostrand Avenue, about 5 km.
Why it’s underrated: all the reasons that make Utica so strong apply to Nostrand secondarily; the present bus ridership may be high enough to support two subway lines rather than one. The present terminus was built as a temporary one, which is why it has side platforms rather than an island platform.
What is being done right now: nothing.
New York Finds Massive Savings in Transit Construction
MTA Chairman Tom Prendergast announced that an internal review of MTA Capital Construction reveals that there are large wastes in the capital budget that could be eliminated with relatively simple steps. City comptroller Scott Stringer noted that Second Avenue Subway’s first phase, a two-mile stub, costs nearly $5 billion, whereas comparable lines in Paris, London, Tokyo, and other rich, global cities are a fraction of that amount. “Few lines cost more than half a billion dollars per mile,” his office added.
Prendergast’s office directed questions to MTA Capital Construction President Michael Horodniceanu. Horodniceanu outlined a list of items raising New York’s subway construction costs, including labor rules, legal issues, lack of training in new technologies, and insufficient public oversight of contractors. He added that there is little hope of seeing large reductions in the costs of ongoing projects, which are too far advanced, with most of the money already spent, but future subway construction could be done for much cheaper. He did not give a concrete estimate, but a senior official at MTA Capital Construction believed that with the requisite reforms, future subway lines would cost about half a billion dollars per mile in Manhattan and a quarter billion dollars in the Outer Borough.
When asked about the possibility of building Amtrak’s Gateway Project at lower cost, the source qualified those estimates, explaining that Gateway can probably be done for $3 billion, closer to a billion dollars per mile, as much of the project involves underwater tunneling. Officials from Amtrak did not comment on the record by the time this story went to press; however, a senior Amtrak manager speaking on condition of anonymity said, “we don’t really believe this is possible – there are lots of low estimates, and those always lead to budget overruns,” and said that the cost figures from the rest of the world are “irrelevant to America and American labor costs.”
Labor reactions to the announcement were mixed. James Ryan, the president of the Sandhogs Local 147 union, expressed skepticism that costs could be brought down without cutting wages or unionized jobs, and warned of a “race to the bottom” and a “low-wage Wal-Mart economy.” However, he added that he would accept changes as long as there was a guarantee of no job losses, wage cuts, or work rule reforms that would reduce union autonomy. TWU Local 100 President John Samuelsen, whose union represents subway workers rather than construction workers, proposed that the city and the state use the reduced costs to expand subway construction, specifically mentioning future phases of Second Avenue Subway. Currently only Phase 1 is funded, serving the Upper East Side.
Reactions within the state legislature were more positive. The greatest supporter is Assembly Speaker Sheldon Silver (D-Manhattan), whose Lower East Side district is slated to be served by the fourth and last phase of Second Avenue Subway. Silver noted that he was in support of the project even when it was just Phase 1, and said that he would work with the State Senate to pass all the legal reforms requested by Prendergast and Horodniceanu. In the State Senate, co-temporary presidents Dean Skelos (R-Long Island) and Jeffrey Klein (Ind. D-Bronx) had a cooler response. They both praised the revelations and said that they would consider passing the reforms requested, but did not mention any timeline for doing so. Several state legislators, speaking on condition of anonymity, expressed sentiments that the MTA is keeping two sets of books, and if the MTA just admitted to being able to save more money, then its budget requests for operations are also likely suspect. Skelos himself was cool to the proposals for a legislative audit of the MTA, but added, “I understand why people are upset and want to take a closer look.”
In contrast, within City Hall, reactions were overwhelmingly positive. The office of Mayor Bill de Blasio praised Horodniceanu and sent a press release calling MTA Capital Construction’s announcement “a courageous admitting of past mistakes, and an ambitious look forward.” De Blasio himself added that “Now is the time to see where we can build new lines that we thought were unaffordable,” and expressed confidence that all necessary changes can be achieved without running afoul of labor demands.
It is unclear whether the city or the MTA will propose any subway extensions, other than the completion of Second Avenue Subway. In 2008, the MTA’s then-chairman, Elliot Sander, proposed a 22-mile circumferential line running on lightly-used freight rights-of-way, connecting the Bronx, Queens, and Brooklyn without going through Manhattan. Regional Plan Association President Robert Yaro noted that his organization initially proposed this line in 1996 and proposed that the MTA build this line as well as express links to all three airports. He added that this line, which he calls Triboro, requires only about a mile of tunnel and is therefore much cheaper than fully underground lines. “The MTA has found a way to make everything cheaper, both subways and construction on existing infrastructure, so Triboro will be especially cheap now,” he said.
The community groups who could be reached by the article’s deadline were split. Transit activists within Harlem proposed that Second Avenue Subway be modified to add a fifth phase, going crosstown under 125th Street. The members of Harlem’s three community boards agreed that it would be useful, but most of them expressed concerns that it would lead to gentrification and displacement of existing residents, and said they would support the line if the city made an effort to build or preserve affordable housing. MTA planners who spoke on condition of anonymity proposed to extend the 2 and 5 down Nostrand Avenue in Brooklyn and the 4 down Utica Avenue, as per proposals from the 1970s. The response of the community boards in southeastern Brooklyn was more negative, saying that it would change the character of the neighborhoods relatively. One community board member warned that this would lead to “Manhattanization of our neighborhood.”
No member of the New Jersey state government responded to repeated requests for quotes by the article’s deadline.
Transit Observations from Philadelphia
I was in Philadelphia last summer for about five days. I have few observations as a pedestrian: I stayed in West Philadelphia, in the gentrifying zone radiating out of University City, and traveled to Center City, and both neighborhoods seemed intimately familiar to me as a (former) New Yorker. The street widths and setbacks looked very much like those of New York; West Philadelphia could easily be an area of Brooklyn. The difference to me was in the public transit rather than the pedestrian experience.
In New York, the subway is for everyone. The same is true of Singapore and Vancouver. In Philadelphia, it is not the case. The city is about 40% white and 40% black. On the trains I took, the Market Street subway and the Subway-Surface Trolleys, nearly everyone was black. A friend who lived in Philadelphia for ten years has observed the same on the buses, and adds that white people on buses tend to be college students.
But there’s more to the story. I think it’s a commonplace that in American cities other than New York, blacks ride public transit more than whites. What I think is more important is that whites tend to ride transit at rush hour. When I rode the trains in Philadelphia at rush hour, there was still a clear black majority on the streetcar or the subway car, but there were a fair number of whites. In the off-peak, I was at times the only white person on a streetcar that was filled to its seated capacity. The aforementioned friend says she thinks she saw the same, but as she rarely rode at rush hour, she is not sure.
It is not hard to come up with explanations for the difference. In Philadelphia, as in the typical Rust Belt city, the white population is quite suburbanized, much more so than the black population. It is also substantially richer. Both contribute to car ownership, and to driving in whenever traffic allows; since traffic is worst at rush hour, that’s when we see the most white people on public transit. The people who ride the trains and the buses outside rush hour tend to be urban residents who do not own a car, and in a city with the income distribution and racial dynamics of Philadelphia, they are predominantly black.
This injects a racial element into a lot of transit planning, especially for commuter rail. North American commuter rail is designed exclusively for suburban residents, who in Philadelphia and similar cities are usually white and at least middle-class. This is why it gets away with such poor off-peak service: hourly on most SEPTA Regional Rail lines, hourly or even every two hours on the MBTA, hourly on most branches of the New York commuter rail network. Although New York itself doesn’t have the typical Rust Belt city demographics, its suburbs have typical Rust Belt suburb demographics, so the situation is the same. The same is true of Boston, when one remembers that a huge fraction of its urban white population is in Cambridge and Somerville. Philadelphia is only where this racial division is the most obvious even on the subway.
Everything about North American commuter rail screams “you’re better than the hoi polloi who ride the subway”: the seating arrangement maximizing seating rather than standing space, the park-and-rides, the fares, the lack of fare integration with local transit, the schedules. Since peak-only suburban transit serves precisely the niche that the traditional white suburban middle class is comfortable riding transit in, it is necessarily segregated. Its riders even fight to keep it that way: witness for example the opposition in Stamford to developing the Metro-North station and moving the parking 400 meters away. This article complaining about parking lot waits is typical of the species; these complaints persist despite very high spending on commuter rail parking lots, for example in Hicksville.
The same transit agencies that fudge or make up numbers to avoid serving minority neighborhoods also ignore the possibility of improving off-peak service. Although off-peak service is cheaper to provide than peak service – it requires no new vehicles or infrastructure and fewer split-shift crews – the plans for service expansion typically focus on more peak capacity, despite often high crowding levels on off-peak trains. This is worst on commuter rail, but also affects subway and bus systems. In New York, the MTA’s crowding guidelines call for setting off-peak frequency such that the average train on each line will have 25% more riders than seats at the most crowded point of its journey. As anyone who’s ridden trains in Manhattan in the evening knows, trains are quite often much more crowded than this average. The MTA needs to keep its losses to a reasonable minimum, and on the core lines the off-peak frequency is not bad; but why keep claiming that trains only have 25% more riders than cars? The MTA is by comparison more honest about its capacity problems on the Lexington express trains, for example in the Second Avenue Subway environmental impact statement.
Many of the problems of American transit systems are directly traceable to the fact that the managers don’t often ride the trains, and their peer group is not the same as the average transit user. This is why we see little concern for off-peak service, and practically none with off-peak service on the whitest and more suburban form of transit, commuter rail. None of these managers of course intends to be racist or classist, but they unwittingly are.
The Difference Between Bus and Subway Alignments
Reading design guidelines for bus routes reminds me of how different surface transit is from rapid transit. Buses need to follow straight, wide, two-way roads. Subway trains do not: those roads make construction easier, but it’s normal for train lines to detour and turn, even in rigidly gridded cities like New York. The upshot is that sometimes the optimal route for a bus is different from that of a subway, and this limits the usefulness of preexisting bus routes for subway planning.
For a relatively simple example of this, consider the plans for a subway under Wilshire Boulevard in Los Angeles. The buses follow Wilshire all the way from Downtown to Santa Monica. The trains were never intended to: there’s a short stretch where Wilshire isn’t as important while somewhat off the street lies Century City, and all alignments studied for the Wilshire subway have involved some deviation. The chosen alignment is the one that deviates more than the other, to serve Century City more centrally.
This is relevant specifically to the example of Tel Aviv. When I criticized the Tel Aviv subway route choice for being politically motivated to avoid certain neighborhoods, Alan of Tel Aviv Bus Mappa said,
To minimise cost, the planners looked at what works today (the existing high-demand bus routes) and decided that connecting Petah Tikva and Bat Yam to Tel Aviv was the highest demand corridor. They also looked at what was wide (boulevards and arterials), as their aim was to maximise segregated on-street running. This is also the reason that the plan makes use of the ‘Turkish line’ alignment connecting Jaffa and Allenby rather than the more direct, but narrow, Derech Yafo and Eilat Street.
Central Bus Station would have been a huge diversion for the route and is not a particularly in-demand destination. However, the planned Green line will serve that location.
The problem with this line of thought is that subways are not buses. Subways can use the more direct but narrower alignments if they need to: it may be somewhat more expensive to construct, but there’s no disutility to passengers. A bus running on a narrow street is slowed down, especially if the street is twisty. A subway that can go under private property is not.
Even in New York there are some twists – for examples, the route of the L through Brooklyn, and the route of the 2/3 from the Upper West Side to Harlem. But those twists are not critical, and the city doesn’t really need them. The Wilshire deviation in Los Angeles is also in this category.
It’s ungridded cities where the ability of trains to cut under the street network becomes critical to providing service to major destinations, which may not be anywhere near the wide streets. A look at the inner network of the London Underground will confirm that the lines bear little relationship to the street network, which was built incrementally over the centuries and would not be good at serving the major destinations in the desired directions. In Paris the older lines were built subsurface and do follow streets (which at any case are more rationalized than in London due to heavyhanded central planning), but the newer ones were built deeper and do not.
In Tel Aviv, the problem is that many of the neighborhoods that need public transportation service the most do not have wide streets for buses, or have wide streets configured in the wrong directions. The oldest parts of the city, the Old City of Jaffa and Ajami, have very narrow streets since they predate modern boulevard design by a few centuries. The next oldest – the Jewish neighborhoods of Jaffa, South Tel Aviv, the western parts of Central Tel Aviv, and the Old North – do have wide streets, but often pointing in the wrong direction, for examples nothing serves the Port or the Basel Heights compound, and the east-west streets going through the Old North are very narrow. They have no reason to form a coherent rapid transit network, since they were built as interurban streets or as neighborhood main streets, not as subway alignments. They barely even form a coherent bus network, but the hacks made over the decades to create bus trunk lines are different from the optimal route a subway would follow.
In fact, the recently-reelected Huldai administration has plans to upzone around the central parts of the route to build a new CBD. The area in question, around Begin Road, is unwalkable and almost unfixable to be made pedestrian-friendly, the road is so wide and fast. This is not service to an existing destination that follows a linear corridor as in New York and other strongly gridded cities.
In a city like Tel Aviv – or any other city without a strong grid that influences development – subway planning should start from a list of major destinations and dense residential neighborhoods and their locations on a map. The subway routes should form somewhat straight lines connecting them, with the first line chosen in a way that connects to the most and the most important ones. It’s fine to have somewhat kinked routes – nobody likes riding a C-shaped route, but it’s okay to have small deviations such as the ones proposed for Wilshire or even larger ones such as the one Shanghai’s Line 1 takes to reach People’s Square. The junctions should be the most important destinations, or the ones with the most potential for CBD formation; in Tel Aviv those are generally to the west of the planned CBD, because of the potential for waterfront upzoning and the preexisting density in the neighborhoods south of the Yarkon and west of the Ayalon Freeway.
Buses are of course not planned like this. A city that wants a vigorous bus network needs to do what Los Angeles and Vancouver have done: put the buses on a grid as much as possible, and have them go straight along major roads, with as few deviations as possible. Vancouver’s north-south buses deviate a little bit to serve Downtown, and even those deviations are sometimes questionable since people transfer from the buses to SkyTrain before the buses reach Downtown. The grid allows for an efficient network of transfers, with the transfer penalty reduced by high frequency on the trunk lines. It’s nothing like subway lines, which form a tight bus-like mesh in about one city in the world (Mexico City) and everywhere else have a mesh-like core surrounded by what is an essentially hub-and-spoke system.
Even when the busiest bus routes do indicate something about subway demand, there are exceptions. In New York, the busiest bus lines today are the M15, on First and Second Avenues, and the B46, on Utica Avenue: they are almost even in ridership and have traded places for first place citywide recently. But nobody expects a Utica subway to get the ridership of Second Avenue Subway, even people like myself who believe such a subway is underrated and should be considered in medium-term transit planning. The third busiest route in New York is the Bx12, on Fordham, and I do not know a single transit activist who believes it should be railstituted, even ones who believe other routes with somewhat lower ridership should be railstituted (such as Nostrand, whose bus, the B44, ranks fifth). The issue here is that First and Second are in Manhattan, where bus speeds are so low that ridership is suppressed, as people walk longer distances to the parallel subway or don’t take the trip; if both Second and Utica get subways, the lower amount of congestion in outer Brooklyn is irrelevant and the trains will travel at the same speed, whereas today there are factors working against Second that make the rail bias there higher than on Utica.
Something similar is the case in Tel Aviv. The widest boulevards have the largest concentrations of bus trunk lines, but that’s because they are the only streets on which buses are even remotely feasible as modes of transportation. In Jaffa, Jerusalem Boulevard is wide enough for fast surface transit but Yefet Street is not. Based on Jerusalem’s width, the planners chose to keep trains at-grade on Jerusalem, which they could not do on Yefet. But if trains were underground, Jerusalem’s current advantage would evaporate, leaving Yefet with the advantages of proximity to the Old City and the Flea Market and of higher density.
It is wrong to plan buses as if they were subways or early-20th century streetcars, where frequent twists were not a problem since there were few cars on the road, and where the dominance of the traditional downtown favored a hub-and-spoke network. Recent bus successes in North America have involved discarding those ideas and planning buses based on modern travel needs and modern traffic levels. By the same token, it is wrong to plan subways as if they were buses when they are capable of following alignments that buses cannot.
More on Vancouver’s Obsession With Filling Buses (Hoisted from Comments)
Via Human Transit, I learn that Translink has a bus service performance summary with an infographic on PDF-page 16 contrasting high- and low-performing routes. As usual, Translink claims that the high-performing routes have strong anchors at their ends as one of the reasons for their success. Unfortunately, the claim is not completely correct, and on top of that the definition of “high-performing” is stretched to make anchored routes look better. In particular, this implicates Vancouver’s strategy of upzoning the most intensely at its southern rim while ignoring its center.
To paraphrase my second comment on Human Transit, the summary rates routes on three metrics: boardings per hour, capacity utilization, and cost per boarding; a high-performing route is one that is in the metro area’s top 25 on all three, and a low-performing one is one that is in the bottom 25 on all three. However, only the first and the third are actually useful for the passenger. The second is a measure of pain – it’s the product of turnover with crowding, and although it can be raised by raising turnover, it can also be raised by making the bus more crowded.
An updated list of Vancouver buses and their productivity measures is available here. Measured by cost per rider and boardings per hour, the unanchored 8 is more productive than the 49, which has anchors but nothing in between. But the 8 ranks 29th in capacity utilization, so it’s penalized. The 5 and the 6, which are very short routes serving the West End, are also penalized solely because of their low crowding levels and their short length, which makes turnover more difficult. The 8 has high turnover (like the 3 and 20, which did make the infographic), so it achieves more passenger boardings per hour but fewer passenger-km despite its weak outer-end anchor, and the 5 and 6 are so short that even passengers riding all the way through provide many boardings per hour relative to capacity utilization.
Translink unfortunately does not break down capacity utilization into its two components, and only cites the crowding level at the most crowded point of the average trip. But we can still construct a table of some routes with their performance on the three metrics as well as their crowding level:
| Route | Boardings/hr | Capacity use | Peak Crowding | Cost/boarding |
| 3 | 113 | 110% | 49% | $0.89 |
| 5 | 105 | 67% | 53% | $0.95 |
| 6 | 98 | 68% | 48% | $1.02 |
| 8 | 102 | 98% | 41% | $0.98 |
| 9 | 103 | 160% | 64% | $0.97 |
| 20 | 113 | 124% | 50% | $0.89 |
| 25 | 81 | 187% | 74% | $1.23 |
| 41 | 105 | 180% | 78% | $0.95 |
| 49 | 96 | 169% | 82% | $1.04 |
| 99 | 176 | 167% | 86% | $0.57 |
The 3, 9, 20, 41, 49, and 99 are in the infographic on the list of most productive routes; the 25 narrowly misses on cost per passenger and boardings per hour but is second systemwide in capacity utilization, and the 5, 6, and 8 miss only on capacity utilization. The 25 and 49 have strong anchors at their outer ends, a single strong central anchor at the Canada Line, and nothing else; On the metrics relevant to the passenger who’s expected to ride the bus and fund it by paying a fare, they are somewhat lower-performing than the short 5 and 6 and the short-trip-encouraging 3, 8, and 20, but have far more crowding. The 9 and 41, both in the infographic, are about on a par with the 3, 5, 6, 8, and 20, and have more turnover due to additional destinations on Broadway and 9th that don’t exist on King Edward and 49th, but are still much more crowded than the unanchored routes. The 99 beats all others in performance, but the cost in terms of crowding is even higher.
The purpose of anchoring is explicitly to keep buses full all the way; the 25 and 49 are great at that, since people ride them longer distances, not having much to go to between their major destinations. However, it’s not a measure of passenger satisfaction or of transit agency finances, but of passenger-km. The surreptitious focus on passenger-km is dubious as a performance metric for urban transit, since transit-using city dwellers usually prefer shorter commutes and do most non-work trips on foot.
And if it’s dubious as a transit proposition, then as an urbanist proposition it’s destructive. As discussed in my previous post on the subject, Vancouver is upzoning Marine Drive (slightly) more intensely than the area south of Broadway and near the stations on the Canada Line between Broadway and Marine Drive – see PDF-pp. 26-27 of the draft plan. Despite the hysteria about urban planners using social engineering to make people live close to city center and take transit instead of driving, here we have a city with an otherwise well-deserved reputation for greenness using social engineering to make people live farther out.
This focus on anchors is making Vancouver build itself to be on a regional scale like how the 25 and 49 look on the local scale. The famous high-rise Vancouverism is really about looking like the 5 and 6 – i.e. upzoning near Downtown so that people will walk or take short trips – but future development is not intended to occur near Downtown but rather in strategically chosen secondary CBDs farther away. And what is really needed is continuous corridor development, as is practiced on the corridors hosting the 3, the 8, and the 20.
Tel Aviv Needs a Subway, Done Right
After decades of false starts, Tel Aviv is finally building a subway-surface line. The political opinions of activists and urban planners in Israel are divided between supporters, who believe the line is long overdue, and opponents, who instead believe buses remain the solution and also oppose the Jerusalem light rail. I on the contrary think that on the one hand Tel Aviv needs a subway, but on the other hand the current plan has deep flaws, both political and technical, and is learning the wrong lessons from recent first-world greenfield subways.
In some ways, the Tel Aviv subway resembles New York’s Second Avenue Subway. It passes through neighborhoods that are very dense – the line under construction connects some of the densest cities in Israel, albeit poorly. Nobody believes it will be built because of all the false starts. Real incompetence in construction leading to cost overruns has led to speculation about much greater cost overruns.
For nearly a hundred years, the conurbation around Tel Aviv and Jaffa has been the largest metro area in what is now Israel; it is also the largest first-world metro area outside the US that has no urban rail. There were preliminary plans for a Tel Aviv subway in the 1930s, followed by repeated plans since independence, all of which were shelved. A proposal from just after independence for developing coastal Israel around rail and rapid transit trunks was rejected by Prime Minister David Ben Gurion because it conflicted with the political goal of Jewish population dispersal; to further its political goals, the state concentrated on building roads instead. In the late 1950s there was a new integrated national rail plan that was not implemented. Haifa got a six-station, one-line funicular, but Tel Aviv and Jerusalem remained bus-only. In the 1960s a skyscraper in Central Tel Aviv was built with a subway station, but there were no tunnels built; a subsequent 1971 plan was abandoned in 1973 due to the Yom Kippur War. The current subway plan dates to the 1990s, and has suffered from repeated delays, and construction only began recently, with opening expected for 2016.
Unlike in the North American debate, in Israel the left is pro-BRT and anti-rail, due to a long tradition of mistrust in mainstream (center-right to right-wing) politics. The same is true of urban planners who follow the Jacobsian tradition, such as Yoav Lerner Lerman (Heb.). The article I translated two years ago about Jerusalem’s light rail is in that tradition: it attacks genuine problems with cost overruns and a politicized route choice process, but then concludes that BRT is the solution because it’s been implemented in Curitiba and Bogota successfully. The result is that people whose ideas about trade, energy, health care, education, and housing are well to the left of what is considered acceptable in the US end up channeling the Reason Foundation on bus versus rail issues.
In reality, Tel Aviv’s urban form is quite dense. The city itself has 8,000 people per square kilometer, much lower than Paris and Barcelona, but higher than most other European central cities (say, every single German city). Like Los Angeles, its municipal borders do not conform to the informal borders of the inner-urban area, since it contains lower-density modernist neighborhoods north of the Yarkon, while dense Ramat Gan, Giv’atayim, Bnei Brak, and Bat Yam are separate municipalities. The inner ring of suburbs, including the above-named four, has 7,400 people per square kilometer; excluding the more affluent but emptier northern suburbs, this approaches 10,000/km^2.
However, the urban form is quite old, in the sense that the density is fairly constant, without the concentrations of density near nodes that typify modern transit cities. Tel Aviv’s residential high-rise construction is not very dense because it still follows the modernist paradigm of a tower in a park, leading to low lot coverage and a density that’s not much higher than that of the old four-story apartment blocks. The Old North achieves about 15,000 people per square kilometer with a floor area ratio of 2: the setbacks are such that only about half of each lot is buildable, and there are four floors per building. The Akirov Towers complex averages about 2.5.
Although this density pattern favors surface transit rather than rapid transit, Tel Aviv doesn’t have the street network for efficient surface transit. Paris, a poster child for efficient recent construction of light rail (see costs and ridership estimates on The Transport Politic), is a city of wide boulevards. Central Tel Aviv has about two such streets – Ibn Gabirol and Rothschild – and one auto-oriented arterial, Namir Road, which the subway line under construction will go under. The street network is too haphazard to leverage those two for surface BRT or light rail, and the major destinations of the central areas are often on narrower streets, for example Dizengoff. On top of that, light rail speeds in Paris are lower than 20 km/h, whereas newly built subways are much faster, approaching 40 km/h in Vancouver and Copenhagen. Outside Central Tel Aviv, the roads become wider, but not nearly as wide as those used for BRT in Bogota, and there is nothing for surface transit on those streets to connect to on the surface. A surface implementation of Route 66, following Jabotinsky Street (the eastern leg of the subway line under construction) in Ramat Gan, Bnei Brak, and Petah Tikva, wouldn’t be very fast on the surface to begin with, but would come to a crawl once crossing the freeway into Tel Aviv.
Tel Aviv also has two more important reasons to imitate Vancouver and Copenhagen, besides speed: religious politics, and economic and demographic comparability. Public transportation in Israel operates six days a week, with few exceptions, to avoid running on the Sabbath. A driverless train, built to be quiet even on elevated sections, with no turnstiles and free fares on the Sabbath, could circumvent religious opposition to seven-days-a-week operation.
Even without the religious question, Copenhagen and especially Vancouver are good models for Tel Aviv to follow, more so than middle-income Curitiba or Bogota. Israel is a high-construction cost country, but Canada is not very cheap, and Vancouver has cut construction costs by making elevated trains more palatable and reducing station lengths. Greater Tel Aviv has 2.5-3.5 million people depending on who you ask, not much higher than the range for Copenhagen and Vancouver. Tel Aviv is about as dense as Copenhagen and Vancouver, though Vancouver’s density is spikier. Tel Aviv expects fast population growth, like Vancouver, though in Tel Aviv’s case it’s a matter of high birth rates whereas in Vancouver it’s only immigration.
One way in which Vancouver is not a good model is the role of regional rail. Israel has no equivalent of Transport Canada or FRA regulations. It even connected Tel Aviv’s northern and southern rail networks and through-routes nearly all commuter and intercity trains. However, the network has real limitations, coming from its poor urban station locations, often in highway medians; the through-running project was completed simultaneously with the construction of the freeway. For example, the Tel Aviv University station is located far downhill from the actual university. As a result, even when there is development near the train stations, it is usually not walkable. This compels new rail service with stations in more central locations as well as east-west service, complementing the north-south mainline.
However, for service to the less dense suburbs, the construction of new lines, and electrification of the entire national network (so far only the Haifa commuter network is scheduled for electrification), should provide the backbone. There is no integrated planning between regional rail and shorter-distance urban rail, the first failing of the current plan.
More broadly, the plan fails not just because of the wrong mode choice – subway-surface rather than driverless metro with a regional rail complement – but also because of how it treats urban geography. The proposed network – on which the red line is under construction and the green line is intended to be the second built – is too sparse in the center, and ignores the older urban centers. The phasing ignores preexisting transportation centers, and often the choice of who to serve and how to serve them is political.
The worst political decision concerns Jaffa, the old core of the metro area. (Tel Aviv was founded as a nominally independent city, but really as a Jewish suburb of Jaffa.) The most activity is in the Old City and the Flea Market, going down along Yefet Street to Ajami, since 1948 the only majority-Arabic speaking neighborhood in the municipality, and the only neighborhood that is completely unplanned. The streets are narrow, favoring a subway, and the residents are poor and have low car ownership rates. Instead, the route through Jaffa is on the surface and follows Jerusalem Boulevard, a less busy road built by the city’s then-mayor out of envy of then-separate Tel Aviv’s Rothschild Boulevard. This serves the more gentrified Jewish parts. Ajami is gentrifying – it’s close to Central Tel Aviv, is right next to the coast, and has stunning architecture – but is still majority-Arab.
The other neighborhood that due to ethnic differences is viewed separately from Tel Aviv, Hatikva, is also underserved. In this case, the residents are Jewish, but are predominantly Mizrahi and traditional-to-religious, with high poverty levels. The plan does serve Hatikva, but much later than it should given the neighborhood’s density, intensity of low-end commercial activity, and proximity to Central Tel Aviv. A northwest-southeast line, following Dizengoff and then serving Central Bus Station (a larger transportation center still than any mainline rail station) and Hatikva before continuing east into the inner suburbs, should be a high priority, but isn’t. The Central Bus Station area is also a concentration of refugees, another low-income, low-car ownership population, though since this concentration is more recent than the plans for the subway, the lack of priority service to the bus station is not a result of racism.
It’s not only about class reasons, or racial ones: Tel Aviv had to fight to get the Ministry of Transportation to agree to build the second line underground under Ibn Gabirol, and that’s to an upper middle-class Ashkenazi neighborhoods. The common thread within the city proper is a preference for new modernist luxury towers over serving existing walkable density, even when that density is hardly lower than what the towers are providing. (The towers can be built more densely, with less open space; by the same token, the low-rise buildings could be upzoned from one half the lot and four story to three-quarters and six stories.)
Another example of bad politics is the way military bases are served. The very center of Tel Aviv is home to the Ministry of Defense and the main military headquarters, the Kirya. The inner urban area is ringed with much larger military bases, including Tsrifin to the south, Glilot to the north, and the Bakum to the east. But the officer corps is concentrated in the Kirya, while Tsrifin is a more general base, Bakum is dedicated to new draftees so that they can be told what unit they’re to be sent to, and Glilot is somewhat higher-end than Tsrifin due to its role in military intelligence but still lacks the Kirya’s concentration of high-ranking officers. Since draftees almost never own cars and often ride buses for hours, the three outlying bases are all natural outer anchors for lines, and Glilot and Tsrifin both lie on easy spurs from the mainline rail network. Despite this, there are no plans for regular service, while the Kirya is part of the subway line under construction and is the intersection point with the second line to be built.
Even on pure geography, the plan makes critical mistakes. The eastern leg of the line under construction is much better than its southern leg: it goes straight from the train station through Ramat Gan and Bnei Brak to a secondary anchor in Petah Tikva. And yet, the station spacing in Bnei Brak, the densest city in Israel, is the widest, even though higher density allows shorter station spacing. In contrast, the surface segment in less dense Petah Tikva is intended to have denser stop spacing. Moreover, despite the advantages subway-surface operation has in terms of branching, the branching is meant to be really a short-turn, with half of all trains going straight to the depot still in the underground section and half continuing to Petah Tikva. Central Petah Tikva is well to the south of the line, which is intended to terminate at Petah Tikva’s peripherally located central bus station, but there is no branch serving that center, despite high intended frequencies (3 minutes on the surface, 1.5 minutes underground).
I believe that in addition to an electrified mainline rail trunk, Tel Aviv needs a driverless subway network that looks roughly like an E: one or two north-south lines (west of the freeway if one, one on each side if two), three east-west lines intersecting the mainline rail at the three main Tel Aviv stations. The east-west lines should be anchored at the eastern ends at Petah Tikva, Bar Ilan University, and the Bakum or Kiryat Ono; the north-south lines should go about as far north and south as required to serve the center, letting mainline rail take care of destinations roughly from Glilot or Herzliya north and from Tsrifin south. Such a network would not serve political goals of making Tel Aviv a luxury city; it would just serve the transportation goals of the urban area’s residents.
Quick Note: Why Quinn is Unfit to be Mayor
The Triboro RX plan calls for using preexisting freight rail rights-of-way with minimal freight traffic to build a circumferential subway line through the Bronx, Queens, and Brooklyn. It was mentioned as a possible project by then-MTA head Lee Sander and more recently by Scott Stringer and on The Atlantic Cities by Eric Jaffe. Despite not having nearly as much ridership potential as Second Avenue Subway or a future Utica subway, the presumed low cost of reactivating the right-of-way makes it a promising project.
According to Capital New York, leading mayoral contender Christine Quinn has just made up a price tag of $25 billion for Triboro, while claiming that paving portions of the right-of-way for buses will cost only $25 million. This is on the heels of city council member Brad Lander’s proposal for more investment in bus service. The difference is that Lander proposed using buses for what buses do well, that is service along city streets, and his plan includes bus lanes on major street and what appears to be systemwide off-board fare collection. In contrast, Quinn is just channeling the “buses are always cheaper than rail” mantra and proposing to expand bus service at the expense of a future subway line.
There is no support offered for either of the two cost figures Quinn is using, and plenty of contradictory evidence. Paving over rail lines for bus service is expensive; a recent example from Hartford and a proposal from Staten Island both point to about $40 million per km in the US. The map in the Capital New York article suggests significant detours away from the right-of-way, including on-street turns making the bus as slow as the existing circumferential B35 route, but also several kilometers on the railroad in Queens. Conversely, reusing rail lines for rail service is not nearly as expensive as building a subway. The MTA’s own biased study says a combined on-street and existing-right-of-way North Shore service would cost 65% more if it were light rail than if it were a busway; since the Triboro right-of-way is intact, the cost of service is in the light rail range, rather than the $25 billion for 35 km Quinn says.
But the reason Quinn is unfit for office rather than just wrong is the trust factor coming from this. She isn’t just sandbagging a project she thinks is too hard; the MTA is doing that on its own already. She appears to be brazenly making up outlandish numbers in support of a mantra about bus and rail construction costs. Nor has anyone else proposed a Triboro busway – she made the logical leap herself, despite not having any background in transit advocacy. Politicians who want to succeed need to know which advocates’ ideas to channel, and Quinn is failing at that on the transit front. If I can’t trust anything she says about transit, how can I trust anything she says about the effectiveness of stop-and-frisk, or about housing affordability, or about the consequences of labor regulations?
Update: Stephen Smith asked Quinn’s spokesperson, who cited a $21 billion figure for a far larger RPA plan including Second Avenue Subway and commuter rail through-running with new lines through Manhattan. I am not holding my breath for a retraction of the bus paving plan from the Quinn campaign.
Update 2: Quinn admitted the mistake on the rail plan, and revised the estimate of the cost down to $1 billion, but sticks to the bus plan and its $25 million estimate.
Quick Note: More on Urban Absolutism
In previous posts, I brought up the theory that American cities are run in a feudal fashion, despite the nominally democratic system, and that the failings of feudalism are leading proponents of livable streets and public transit to demand elected absolute monarchs instead. The recent 125th Street bus debacle, and the online livable streets community’s response to it, represent another example of this trend.
To recap: New York City’s Department of Transportation proposed a bundle of bus upgrades along 125th Street: dedicated bus lanes on most of the street for the use of all four bus routes running along 125th, and Select Bus Service on the M60, which connects Morningside Heights with Astoria and LaGuardia. The M60 is by a small margin the top route for boardings along 125th (not necessarily for boardings elsewhere for trips ending on 125th), but it’s third in overall ridership among the four routes. Because of its Morningside Heights bend at the west end and its LaGuardia service it’s perceived as a whiter route than the other three routes: the Bx15, connecting to Third Avenue in the Bronx; the M100, connecting to Washington Heights and Inwood; and the M101, connecting to Washington Heights at one end and going along Third and Lexington at the other. Harlem politicians were livid that DOT were only giving SBS upgrades to the whiter route. State Senator Bill Perkins opposed the plan’s ban on double parking and got the bus lanes truncated from Central and West Harlem to just Central Harlem; he and City Councillor Robert Jackson continued to oppose the plan, Jackson doing so explicitly on the grounds of privileging the M60, and DOT just dropped it.
It is not my intention here to rehash my argument for why Jackson was right and DOT should have proposed SBS upgrades for all four routes, or if it had to pick one then the M101. I have said this on Streetsblog and Second Avenue Sagas in comments. Rather, I bring this up because while many commenters said “we lost, let’s try again” or “we lost, let’s defeat Perkins and Jackson for opposing our interests,” other responded with fantasies of absolute power: fantasies of the city cutting bus routes to West Harlem to punish Jackson and Perkins, fantasies of the city making the Harlem communities beg for any further livable streets improvements (as already happens with bike lanes in East Harlem), fantasies of a Robert Moses for livable streets, fantasies of Bloomberg buying election campaigns to defeat all livable streets opponents.
An absolute ruler is not going to do anything positive. He doesn’t have to – either his rule is secure and he doesn’t need to care, or it’s not and he needs to spend his effort shoring it up with patronage and attacks on opponents. A city government strong enough to do things over the objections of black politicians who are concerned with racial inequality, or over those of pro-car NIMBYs, will also be strong enough to do things over the objections of the livable streets community. Robert Moses’s problem wasn’t just that he was pro-car; it’s that he was authoritarian and didn’t need to care too much about what people thought, so that his own biases for segregation could become city policy.
