State Boundaries and the Northeast (Hoisted from Comments)
Aaron Renn’s repost on US states mattering more than some people imagine made me think about the difference in attitudes toward state lines in different US regions. Aaron’s examples of state lines mattering come from the Midwest, specifically Indianapolis and Columbus. My usual examples of state lines not mattering come from the Northeast. And those two regions treat states very differently.
Imagine a thought experiment in which Congress allows states to redraw their own boundaries – to split, merge, or change borders on their own accord. Let’s ignore the Senate – perhaps it still uses the old boundaries. Let’s also assume that this is not a completely de novo redrawing, akin to the creation of the French departments, in which states are drawn to be of specific size or population.
In such a case, in most of the US, there would be small changes only. Indiana would lose the suburbs of Chicago, Cincinnati, and Louisville, but otherwise remain intact. Virginia would lose the DC suburbs and gain the North Carolina suburbs of Hampton Roads. Tennessee would gain the Memphis suburbs, and maybe possibly lose Chattanooga. Oregon and Washington would merge. California, Texas, and Florida could either survive more or less intact or split based on metro area spheres of influence. I do not know Florida well enough, but my understanding is that Texas and California have strong enough state identity that in a referendum, their major regions would vote against a split. Ohio might have cleaved if it had had only Cleveland and Cincinnati, but I believe the presence of Columbus would make it survive more or less intact. The only Midwestern state that would be completely dismembered is Missouri, which has no equivalent of Columbus between St. Louis and Kansas City.
The opposite is true of the Northeast. From talking to people from both Upstate and Downstate New York, I believe a referendum would result in both sides voting for a split. New Jersey exists as a coherent entity only in jokes about the state made by people from other states. Pennsylvania has at least three regions that do not identify with one another. But at the same time, a coherent Northeast region exists: there are strong migration ties, not only among the four main coastal metro areas but also to and from Pittsburgh and the Upstate metro areas, which have stronger migration ties to New York and Philadelphia than to Cleveland and Chicago. Along the coast, there is also suburb-sharing, which has led to the formation of just four combined statistical areas; there’s even a chain of suburb sharing connecting New York, Allentown (now in the New York CSA), and Philadelphia, and there may soon be direct sharing between New York and Philadelphia.
Unlike in the Midwest or Texas or California, the Northeast does not have the same university-enforced state boundaries, which are probably a major reason why Columbus specifically has migration ties with the entire state but not much with areas just outside the state. In much of the Northeast, a huge number of students go to private universities. In Massachusetts as far as I can tell there are more students at private universities than at public four-year colleges. New York has a very large public university system, but the SUNY/CUNY distinction reinforces the state’s internal divisions rather than erasing them the way Ohio State does.
In terms of a national rail plan, the Northeast practically is a single state (as is the Pacific Northwest, but that’s just two states), from Portland to Quantico. In California, Texas, and Florida, and even Ohio and South Carolina, there are potentially strong in-state intercity rail routes. New York and Pennsylvania have those as well, but both have even stronger routes that cross many states. The Midwest is full of routes that cross states, but usually those connect one or two states to Chicago; the main exception, Chicago-Detroit via Toledo, is indeed not pursued, in favor of the inferior I-94 route that mainly serves Michigan.
Regional rail is similar. It is possible to come up with a plan that’s at least theoretically coherent for regional rail in most parts of the US, to be run by a state agency (or in borderline cases a bi-state agency), or by a local agency with powers delegated by the state. In the Northeast, it’s completely impossible. It’s not even possible to cleanly cleave the region into separate states for the four primary coastal metro areas, because commuter rail services on the Northeast Corridor need to share track with intercity trains at least part of the way, and building infrastructure to avoid such track-sharing is needlessly expensive.
I do not know of a transport association that crosses so many boundaries of subnational entities in Europe. French services are run by the regions; they sometimes cross boundaries, but only in the Midwestern sense of a region bordering Ile-de-France running some of its regional trains to Paris. In Germany, Berlin and Brandenburg have the same transport association, and for all intents and purposes are a single state when it comes to rail network planning. Swiss services cross cantonal borders, but at least the Zurich regional rail network is again French or Midwestern, in that there’s a core of services funded by the ZVV, and services in bordering cantons that run through. In the Northeast, there are good reasons to have commuter services run through from Philadelphia to New York along the Northeast Corridor and maybe also the West Trenton Line; even metro area boundaries are not hard, let alone state boundaries.
Stepping back from the thought experiment, let’s think of how to organize transportation planning in the US. In the Midwest and the South, states are coherent entities. In the West, the areas where states really do not mean much are deep in the Interior West, where there’s no point in building additional ground transportation infrastructure in the first place. But in the Northeast, there may have to be a special exemption treating all of it, including Northern Virginia, as a single state for planning purposes. It can’t be run as tightly as a single state because of its size and its natural division into several metro areas, but some joint service between its various divisions is unavoidable.
More in general, the Ohio example showcases how coherent state identities can be manufactured by the presence of state institutions. On maps that center Cleveland and Cincinnati, such as maps of which baseball and football teams people support, Ohio looks completely dismembered. And yet, the presence of Columbus and Ohio State changes everything when it comes to economic ties such as migration: suddenly, the otherwise-artificial state border means something in terms of social services.
This is not something Northeastern states can really do, nor should they. Pennsylvania has Penn State at State College, but it’s in a small, faraway town, and people who can instead go to Penn or Carnegie Mellon will. New York can expand CUNY and SUNY, but there are too many campuses to provide the same social function of Ohio State. Of course states should expand public higher education, in terms of both opening new campuses where needed and subsidizing tuition, but there’s no room to create a new Columbus; such expansion would provide a necessary service to state residents, but not change economic geography the way it did in Ohio.
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.
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.
The Different Cities We Inhabit
I do not know many people who live in Boston proper. I know about a hundred who live in the Greater Boston area, but only a small minority lives in the city proper, as is of course true in general. I know many people who live in Boston suburbs or in secondary cities like Worcester, but the largest concentration lives in the urban parts north of the river: Cambridge, Somerville, and Watertown. This is true even if I exclude everyone with Harvard or MIT affiliation. In the geek community, Boston proper is where Chinatown is and where the train station is; the social centers are around MIT and Harvard, the jobs seem to be centered in Cambridge as well, and Brandeis graduates often gravitate toward Cambridge and Somerville.
What this means is that I don’t know what people in Greater Boston think about things very reliably. I know the attitudes in Greater Cambridge, or at least the part of Greater Cambridge that goes to conventions. Just as the Providence I inhabited was really a Greater East Side, one in which more people know more residents of Back Bay than of Olneyville, the Greater Boston I inhabited is a specific subculture that’s very active in New England, with specific attitudes that aren’t found elsewhere. For example, support for public transit is quite high, while at the same time enough events don’t and can’t take place in the urban core that people still figure cars are needed, leading to a culture of carpooling.
I keep being reminded by this every time I read pieces by Aaron Renn about attitudes in a city. His latest piece about gentrification is a more subdued example since he talks mostly about the actual effects of gentrification, but the point about people’s attitudes toward it is still there. An earlier piece about Rhode Island mindsets is more indicative. To Aaron, people in and around Providence identify with the state or with their local town rather than with the region. The people I have met are not like that, and often live in southern Massachusetts while still identifying with Providence somehow. For example, one of the Waterfire performers performs in Plymouth and Providence (and Providence is the bigger draw) and lives just outside the census-defined Providence metro area. For another example, I know a recent Brown graduate who is from a Providence suburb of Massachusetts who identifies with Rhode Island and southern Massachusetts, having gone to another college in Providence and to grad school at Brown.
The upshot of this is that it is extremely hard to make any generalization about a city from our own social circles. I live in social circles that are well within Richard Florida’s creative class, but aren’t really what urban leaders seem to care about. I went to a Providence event called Geeking Out once, and it turned out to be about subsidizing smartphone app developers. It’s clearly geeky; it also has no overlap with the geeks I know who teach children how to build robots, or go to fandom conventions. When we talk about cities and urban politics, we never say things like “the city needs to attract more talent.”
But the same difficulty of generalization of course affects the elites as well as people who perceive themselves as normal. If Aaron’s experience talking to urban development leaders is indicative of what they too think, then their social circles also consist mainly of other urban development leaders and their immediate families. There is nothing inherently wrong with that, but there is a real danger of overgeneralizing from an unrepresentative social network. Aaron himself doesn’t do this, but people in positions of power do. The New England I inhabited was a bubble in which downtown Boston didn’t really exist; the Providence that the power brokers seem to inhabit is one in which it is more important to improve transit access to the Jewelry District than to South Providence and Olneyville. I say this as someone who in a year in Providence visited Olneyville once and South Providence never, but because I never saw myself as representative of transit riders, I formed opinions based on where preexisting ridership is and where usable rail infrastructure is and not on gut feeling about where service should go. We all have subcultures, but some subcultures think of themselves as more normal than others, and a few think of themselves as not subcultures at all but as representative of everyone.
The Problem with Anchoring
A major idea due to Jarrett Walker, adopted with gusto by Vancouver’s Translink, is that transit should be anchored at both ends. That is, transit lines should have busy destinations at both ends, and should strive to reorient development such that the maximum intensity is near the ends. I was skeptical about this from the start, but now that I live in Vancouver and see the practice every time I go to UBC, I realize it’s much worse.
The Translink document justifying the layout has a figure, Figure 10 on PDF-page 15, showing that if development intensity peaks in the middle, then the bus will be overcrowded in the middle and empty at the ends. In contrast, if development intensity peaks at the ends, then the bus will be crowded but not overcrowded the entire way. Or, as Jarrett says, “If a transit line is operating through an area of uniform density, about 50% of its capacity goes to waste.”
Both in theory and in practice, this argument fails to note that a bus with development at the ends will be overcrowded the entire way, because people will travel longer. If UBC were located around Central Broadway instead of at the very west end of the metro area, people would just have shorter travel time; at no point would there be more westbound a.m. crowding because at no point would there be more westbound passengers traveling at the peak. There would be more eastbound a.m. crowding, but that’s not the Broadway buses’ limiting factor. Of the top four routes for passups, which have far more than the fifth route, three are east-west with strong anchors at both end (UBC at the west, the Expo Line at the east) and one, the third worst, is a C-shaped amalgamation of two north-south routes, with peak development downtown, in the middle of the C.
On a theoretical level, development intensity is a result of high land prices justifying high density, and in an urban area high land prices come from proximity to other urban land. In cities without topographic or political constraints on development, the CBD is always near the center of the metro area, and in coastal cities the CBD is usually near the shore but near the center along the axis parallel to the shore. Major secondary nodes usually arise in areas close to many suburbs, often the richer ones, and there’s travel demand to them from all directions: see for examples La Defense near Paris and Shinjuku and the other secondary CBDs in Tokyo. Some of those nodes happen to be near the shore (UBC, Santa Monica and Long Beach, Coney Island) but most aren’t. Any newly-built anchor will sprout further development around it unless there’s very strong local resistance. To connect all those neighborhoods that lie beyond the secondary CBD, unanchored transit lines are then unavoidable.
We’re left then with anchors that are at geographic edges, such as on shores. Those raise travel distances, because people can only live at one direction from them, so for a given residential density they will have to travel longer on average. They look attractive to transit managers because they also make the buses more uniformly full, but they’re worse for passengers who have to travel longer, often standing the entire way because of overcrowding. They’re not even good for transit agency finance, because urban transit invariably has either flat fare (as is the case within Vancouver proper) or fare that depends on distance fairly weakly. Short trips generate as much or almost as much money for the agency while requiring less effort to run because of lower crowding levels. Trips in which most passengers ride end to end are the least efficient, unless they can overcome this with very high crowding levels all day.
Now, what does help finances as well as the passenger experience is bidirectional demand. Anchors are good at that. However, what’s just as useful in cases of asymmetric peak demand is destinations that are short of the most crowded points. For example, in Manhattan the north-south subways fill as they go southward in the a.m. peak. This means that commercial buildings north of Midtown, generating passenger traffic that either is northbound (hence, reverse-peak) or gets off the train before it gets the most crowded within Midtown, add ridership without requiring running more trains. The MTA’s guidelines explicitly call for matching frequency to demand at the most crowded point of each line based on uniform sets of peak and off-peak crowding guidelines. This favors not outlying anchors, but development sprinkled uniformly along transit lines outside the CBD. The same development in the North Bronx would have low transit mode share (UBC has high transit mode share, but it’s at a geographic edge, and on top of that it has a huge body of students), while on the Upper East Side and Upper West Side it would have high transit mode share. The only outer ends where heavy upzoning is appropriate are those that aren’t really ends, such as Flushing and Jamaica, preexisting secondary centers in their own right to which people take the subway from the west and drive from the east.
De facto, Translink makes cost figures available for each bus route, and we can compare costs per boarded passenger on the east-west routes and on the north-south ones. The east-west routes have an initial advantage because they have bidirectional peak demand, whereas the north-south and C-shaped ones do not, and have few destinations short of the CBD, mainly just on Central Broadway or Commercial Drive. Despite this inherent east-west advantage, cost per rider is not lower on the east-west lines. Of the top ten route numbers, there are five balanced east-west routes: 99, 9, 41, 49, 25; and four north-south or C-shaped ones serving downtown: 20, 16, 8, 3. (The 135 is east-west connecting downtown with SFU, and could be included in either category.) Going in the same order as above, the east-west routes cost $0.61, $1.21, $1.10, $1.31, $1.47 per passenger, while the north-south ones cost $1.02, $1.29, $1.09, $1.06. (The 135 costs $1.32.) The three routes that interline to UBC on 4th Avenue – the 4, 84, and 44 – cost $1.62, $1.30, and $0.78 respectively, averaging to $1.30; the 84 is anchored at the Millennium Line, the 44 is anchored downtown, and the 4 is anchored downtown but also continues farther east.
The 99 is much cheaper to run than the other routes despite its high proportion of end-to-end ridership, but it is also critically crowded and benefits from multiple peaks as it serves both a secondary CBD and a university; it is also express, which among the other routes under discussion is only true of the 44, the 84, and the 135. Among the local routes, the north-south routes are actually a bit cheaper to run than the east-west routes even if we exclude the 4 as a not fully anchored exception. The 20, the 8, and the 3 all have their maximum development intensity at the downtown end with some extra development in their inner areas, near SkyTrain and Broadway, and a lot of medium-intensity development at the tail. This provides suitable short-of-CBD destinations adding passengers at low cost.
For one measure of productivity, we can divide the number of boardings per hour by the average load. The result is the reciprocal of the average number of hours spent by each passenger on the bus; a higher number means each passenger spends less time on the bus, indicating higher turnover, or equivalently more revenue relative to crowding. The 99, 9, 41, 49, and 25 have ratios of 2.79, 3.13, 2.65, 1.93, 2.13; the 20, 16, 8, and 3 have ratios of 3.26, 2.73, 3.57, 3.24. The 20, 8, and 3 again look very good here, helping explain their low operating costs and also their low crowding (they rank 12th, 27th, and 20th respectively in passups but 2nd, 6th, and 7th in weekday ridership). The 49 and 25, both highly anchored routes, do not look as good, and indeed have many passups relative to ridership (they rank 1st and 4th in passups but 8th and 10th in weekday ridership); they have the redeeming feature that they protrude slightly into Burnaby, where zonal fares are higher, but judging by a map of the passups, the 25 seems to get a large majority of its ridership strictly within Vancouver, with Nanaimo Station as the eastern anchor rather than Brentwood.
We can extend this analysis further by looking at New York’s bus operating costs. Cap’n Transit laboriously compiled a spreadsheet of operating cost per New York City Transit bus route. Within Manhattan, the pattern is that east-west routes have much lower operating costs per passenger than north-south routes. The M15, the busiest route in Manhattan with ridership comparable to that of the 99 in Vancouver and with the best finances among the north-south routes, almost breaks even on direct operating costs; most of the major east-east routes are outright profitable counting only direct operating costs. The key difference is that the east-west routes are much shorter, so passengers are paying the same amount of money for less distance. In his own analysis, the Cap’n notes that the express bus with the best finances is also one of the shortest, and that in general the profitable-after-direct-operating-costs buses have many transfer points to the subway, which suggests short trips as well.
Having seen more evidence for the theory that good bus finances require short trips rather than endpoint anchors, we can go back to Vancouver and compare more routes. The busiest north-south route not on the above list, the 2/22, works more like the 16 than like the 20, 8, and 3: not only is the 22 C-shaped rather than terminating downtown, but also it serves corridors that are less busy than Commercial and inner Main, reducing the availability of short trips. The shorter 2, overlying the longer 22, has 3.42 boardings per hour per load, but still costs $1.43 per rider; the 22 has only 2.15 boardings per hour per load and costs $1.61 per rider, and also ranks 3rd citywide in passups versus 11th in weekday ridership. On both the 16 and the 22, the north-south legs (Arbutus and Renfrew for the 16, Macdonald and Clark/Knight for the 22) are streets that aren’t very busy by themselves, but instead act as important cross-streets for Broadway and other east-west streets. Here are Knight, Renfrew, Arbutus, and Macdonald, and here are, by contrast, Commercial, Fraser, and Main, all around the same cross avenue (near but not at 16th).
The same is true of the east-west buses. The 99, 9, and 41 have better finances than the 49 and the 25. They also do better on passups, ranking 2nd, 11th, and 10th versus 1st, 3rd, and 4th in ridership. The 99 has much better finances than all other buses, which can be chalked to its overcrowding, but ultimately comes from continuous intense development all over Broadway making it a prime corridor. 41st has some of this development as well: here is how a strip of it looks close to the cross street I live on. Compare this with 49th and King Edward around the same cross street. This is not cherry-picked: 49th and King Edward just aren’t commercial streets, and even where they act as important cross streets such as at Cambie there’s not much development there. Of course 4th does have this commercial development and is almost as expensive as 49th and King Edward, but its commercial development is discontinuous, and the relatively intense section between Granville and Balsam is short enough that people can walk it.
So what this means for transit-friendly development is that it should not worry about anchoring, but instead try to encourage short trips on local transit. In his original post about Vancouver’s anchoring, Jarrett says of Marine Drive, at the southern edge of Vancouver proper, “From a transit efficiency standpoint, it would be a good place for some towers.” This is not good transit: from the perspective of both costs and ridership any residential development south of Broadway in which people take the bus downtown is equivalent, so might as well put it immediately south of Broadway or at King Edward, 41st, or 49th to connect with the east-west bus routes and let people live closer to work. Commercial development, too, is best placed short of downtown, because if it’s on Marine Drive people will drive to it whereas if it’s along the blocks immediately south of Broadway many won’t.
Better would be to do what Vancouver hasn’t done, and encourage medium-intensity development all over the major corridors, of the kind that exists on Commercial, Fraser, Main, and 41st and allows their respective bus routes to serve productive short trips, generating low costs without excessive crowding. Towers on Marine Drive, to the extent that their inhabitants would even use transit instead of driving, would clog all the north-south buses. Mixed-use medium-rise development running continuously along Arbutus (which already has an abandoned rail corridor that could make a relief light rail line if the Canada Line gets too crowded) and the major east-west corridors would have the opposite effect, encouraging local trips that wouldn’t even show up at the most crowded point of the line. I’ve argued before that this urban layout is good for walkability, but it appears to also be good for surface transit productivity.
This is also relevant to upzoning around SkyTrain stations. There has not been so far any upzoning around Cambie, even though the Canada Line has been in operation for 3.5 years and was approved for construction over 8 years ago, but there will be some very soon. Vancouver’s draft plan, as shown on PDF-pages 26-27, permits 4 floors of residential development on the cross streets with the stations, 6 on Cambie itself, and between 6 and 12 with mixed use near the stations themselves. Continuous commercial development will be permitted only on Cambie between 41st and 49th. This will be of some use to the east-west buses because there will be more destinations at Cambie, but it will not create the same variety of small destinations available on Main, Fraser, 41st, Commercial, and Broadway, not without further upzoning near intersections that are nowhere near SkyTrain. It’s better than the towers of the Burnaby stations, but it’s still not very good. There is commercial upzoning near Marine Drive, but that can’t be very transit-oriented given the location, and it can’t do much for north-south bus productivity since in the nearby neighborhoods car ownership is high.
It’s too late to change the rezoning plan to permit more linear commercial development on the cross streets, but it’s possible to do better when Vancouver gets around to building Broadway SkyTrain. On Broadway itself, general intensification, allowing more residential density and replacing residential-only zoning with mixed-use zoning, should suffice. There is continuous commercial development from east of Cambie to west of Arbutus, with a two-block gap to Macdonald, and a one-block gap between Macdonald and Alma; both gaps are within a few hundred meters of the cross streets and can be closed easily. The Alma-Sasamat gap on 10th is probably too hard, though. The Arbutus-Macdonald gap on 4th can also be closed, though those blocks are nearly a kilometer from where the stations would be. But it’s as important to allow commercial zoning extending as far south as possible on the major north-south streets, especially Arbutus. Continuous mixed-use zoning should extend at least as far as 16th, and maximum residential density should be at a minimum 4 floors and ideally 6, as Arbutus, Macdonald, and 16th are very wide and the intersections feel out of scale to the current 1-story development.
Of course, this principle of design is true only of urban transit, both surface and rapid. Once the stop spacing increases to regional rail levels, it is no longer feasible to have continuous commercial development, and usually the street networks of the different suburbs are separate anyway without continuous arterials. In all cases it’s important to allow commercial zoning around stations, but the spiky development characteristic of the Expo and Millennium Lines becomes a better idea the longer the stop spacing is. Endpoint anchoring also becomes more justifiable at near-intercity scales, such as New York-New Haven or Boston-Providence: the fares are closer to proportional to distance, and also neither New Haven nor Providence is sprouting suburbs at such scale and distance that it’s justifiable to extend Metro-North or the MBTA with their usual stop spacing past those cities. But at the scale of urban transit, or even inner regional rail, the natural endpoint of a line is not a secondary anchor, and transit agencies should control peak-to-base ratios by commercial upzoning along corridors and near many stations outside the CBD rather than by making people ride transit kilometers longer than would be necessary if the zoning were different.
Transit and Place
There is a large class of transit supporters who think that every right-of-way that can be used for transit should be preserved for this purpose, even if it is not very useful. A few overzealous railfans on the message boards opposed the opening of the High Line park and wanted the viaducts to be used for an extension of the 7 train. This is extreme and nowadays the transit activists I know support the High Line while opposing schemes to recreate it in an inferior context. But even serious bloggers like Cap’n Transit, Ben Kabak, and John Morris are opposing plans to create a Low Line out of the abandoned trolley terminal at the Essex/Delancey subway stop, on the grounds that it could be useful for transit one day.
Now, it’s possible that the Low Line idea is bad because people would not want to go to an underground park. But it’s not a problem for transit; the Williamsburg Bridge doesn’t need trolleys since it has a subway running on (and because the bridge is high there is no way a bus could cross it without passing within two blocks of Marcy, the subway stop at the Brooklyn end of the bridge). The lines running on it are in fact underused: as can be seen on PDF-pages 65-73 of the latest Hub Bound Travel Data report, peak-hour traffic on the J/M/Z entering the Manhattan core was one of the lower in the system as of 2010 – higher than the bottom two track pairs (8th Avenue local and Montague) but in a near-tie for third lowest with several others. So there’s not much use for the trolley terminal as a modern Williamsburg Bridge bus (or trolley) terminal.
But what is more important than just the Low Line is place. To succeed, transit needs not only to exist, which it already does in the area in question, but also to have places to connect to. If for some reason the trolley terminal would need to be demolished to build room for foundations for several skyscrapers, it would be an unambiguous win for transit, since it would create more destinations for people to take the existing J/M/Z and F trains to. The surrounding neighborhood might disagree regarding the implications for urbanism, though I’d argue that Midtown-like skyscrapers would be better-integrated into the streetscape than the projects east and south of the station. If the Low Line succeeds as a park, it will be similar: not in the sense of providing jobs for tens of thousands of people, but in the sense of creating a place for people to go to. (In fact, a park has less peaky demand than offices, so it could be better for subway finances even at relatively low levels of usage.)
Last year, I brought up the question of the infrastructure’s highest value mainly as a way of deciding which kind of service (regional, intercity, etc.) should get first priority on any given rail line, but the same is true about transit versus place. In an area with enough transit and not enough place, it’s more important to create more development, for both good urbanism and more successful transit.
This does not mean every proposal to turn a rail right-of-way into a park is good. Despite my skepticism that the Rockaway Cutoff can be a successful rail line, I’m even more skeptical about its value as a park; it’s not in an area that can ever draw many people, since the density (of both residences and jobs) is not high by New York standards and it is far from other destinations that could draw people from outside the nearby neighborhoods. However, in areas that are lacking in good parks, or could use new development, it is better to concentrate on creating place.
For examples of this elsewhere, consider the railyards in Long Island City, Hoboken, and Sunnyside. Two of my earliest posts proposed to build a regional rail station in Sunnyside and then develop the area around it with air rights over the railyard; this is what should be done in an area that needs both transit and place. But in Hoboken and Long Island City, there’s ample transit, and the only use of the railyards is to park trains that can’t do to Manhattan because of lack of electrification or lack of capacity in the approach tunnels. Since parking trains is an inefficient use of space, and both areas have good connections to Manhattan by subway or PATH, there should be plans to remove the railyards and redevelop them to create more place, leaving just enough rail infrastructure to run through-trains, to be parked in lower-value areas. This development can be either parkland or buildings, depending on what is in demand in the area. Based purely on Google Earth tourism, I believe Hoboken does not need additional parks and so development there should be just a new secondary CBD on top of the PATH station, while Sunnyside and Long Island do, and so development there should include parks as well as high-density office and residential construction.
Instead of worrying about turning unused and for the most part unusable transit infrastructure into place, good transit activists should focus on preserving infrastructure that could potentially be used. In the New York area, probably the most useful piece of infrastructure that isn’t currently used is the Bergen Arches, allowing the Erie lines to enter Jersey City at Pavonia/Newport, a more central location than Hoboken; this is one of four options for a location for a new regional rail tunnel from New Jersey to Lower Manhattan, and is arguably the best option for an integrated regional rail network.
In the 1990s there were plans to reuse the Bergen Arches for a roadway, since modified to include both a road option and a rail option, and in 2011 the Christie administration allocated some money to further studies; an analysis from 2004 scored various road and transit options, not including a regional rail network, and gave the highest score to a roadway with a single high-occupancy vehicle and bus lane per direction. (A trail got the second lowest score, after no-build.) Since Jersey City (and the entire region) needs more transit from the north and west, while further formation of place will and should cluster around the waterfront, it’s important to fight any plan to give the Bergen Arches to a non-railroad use unless and until a regional rail plan is formulated that places the New Jersy-Lower Manhattan tunnel at another location.
In contrast, the Low Line should not be a priority. On the contrary, if the park plan is even partially sound, or the place could be reused as another place if the park idea fails, then good transit advocates should support the idea, since it’d be good urbanism. With a few exceptions, good transit requires good urbanism and vice versa.
How Residential Blocks Act As Barriers
Two weeks ago, I found a board game store in Vancouver, and through it a variety of gaming events. The store is located about five blocks from my apartment, and I first saw it from a bus nearly two months after moving to Vancouver. It’s in the same neighborhood; to get from my apartment to the store requires walking on ordinary city streets with sufficient sidewalks and room to cross. However, those streets are residential, and so I have no reason to walk in that direction. It creates a split in what is formally the same neighborhood.
In my section of Vancouver, the two major throughfares are 4th Avenue and Broadway (9th). There is some retail elsewhere (e.g. on Cornwall, which is -1st, and even more so on Granville Island), but it’s not the continuous commercial development on the two major avenues. Even if it’s as big as Granville Island, it requires me to go specifically to it, whereas on 4th I can go until I see something I am interested in. Before I had wi-fi installed in my apartment, which is on 1st but which I got to by taking a 4th Avenue bus, I walked on 4th until I saw a cafe with free wi-fi and sat there.
This continuous retail ends roughly at the cross street I live on. It extends far east: on Broadway it’s to and beyond Cambie, but to the west it ends just west of Arbutus; on 4th, it extends east to about the Granville Bridge. As I said in my first post about Vancouver, the development on Broadway is fairly spiky, with peaks around Cambie, Granville, and Arbutus, but there’s also a base of 1- to 2-story retail. On 4th, the development is just continuous 1- to 2-story retail. The next major street west of Arbutus, Macdonald, has retail clusters at both Broadway and 4th, but on both avenues there’s a two-block residential gap between the Arbutus side and the Macdonald side. Living on the Arbutus side, I learned early that if I walk east there are cafes, stores, and restaurants immediately, and if I walk west there aren’t. The result is that even though in principle Macdonald is in my neighborhood whereas anything more than three blocks east of Arbutus isn’t, I go this far east of Arbutus much more than I go to Macdonald.
The main advantage of grid street networks over the gridless network of e.g. Providence is that they can provide continuous development, making it easy for people to spontaneously walk in all directions. In Providence spontaneity was provided only by the fact that I knew where the various retail clusters on the East Side were; in reality I would almost always go to Thayer rather than Wickenden or Wayland Square. In gridded cities neighborhoods are less formally defined around one center, but instead evolve more organically, since the center can shift over time and the street network doesn’t distinguish it from the boundary with the next neighborhood over.
On a broader level, this spontaneity is a good way to promote more access. If I can walk to interesting retail in more directions, there’s a higher chance I’ll find something that suits my interests, just as the gaming store does. It provides the same benefits as an increase in density or in travel speed, in this case specialization of retail.
Capital-Centric Countries and Regions
Here is a table of various developed countries, as well as some regions of the US, based on how dominated they are by their largest respective cities. The table includes the percentage of the population in the top metro area, and the ratio of the top metro area’s population to that of metro areas 2-4. Different countries have data from different years, but within each row, the data is from the same year. Of course the definitions of metro areas are not consistent from country to country, but I’ve tried to use the more expansive definitions where they are available.
| Area | Pop’n | 1st % | 1st/2nd | 1st/3rd | 1st/4th |
| South Korea | 48.8m | 48% | 6.45 | 9.34 | 16.26 |
| California | 37.7m | 48% | 2.36 | 5.76 | 7.46* |
| US Northeast** | 65.8m | 34% | 2.55 | 2.92 | 3.39 |
| Japan | 127.8m | 28% | 1.9 | 4 | 6.38 |
| Texas | 25.7m | 27% | 1.11 | 3.14 | 3.77 |
| UK | 59m | 23% | 3.72 | 5.36 | 5.96 |
| France | 61.4m | 20% | 5.71 | 6.79 | 9.56 |
| Germany | 82.3m | 14% | 1.93 | 2.08 | 2.17 |
| Spain | 45.6m | 13.5% | 1.35 | 2.67 | 4.51 |
* Sacramento excludes the one county it has in Nevada.
** The Northeast includes Washington, the states to its north and east, and its suburbs in Virginia and West Virginia.
I could not find data for Switzerland, but the Canton of Zurich is 17% of national population; including the neighboring cantons of Schaffhausen, Zug, and Schwyz (all with Zurich S-Bahn service) raises this to 22%; including also Aargau, also with Zurich S-Bahn service, raises this to 29%.
The takeaway from this table is that our usual notions of which regions are more capital-centric (France, UK, Japan, South Korea) and which are less (Germany, most regions of the US) are more than just about the capital’s share of the population. Germany’s difference with France is not just the largest metro area’s share of the population; it’s also the difference between political centralization around Paris and the polycentric economy of Germany, and this is seen in the second-city shares. (And on top of this, the Rhine-Ruhr region is itself highly polycentric, and the stricter definitions of metro area break it into three.)
In the Northeastern US and California, we see huge largest-cities, but also strong second cities. This is true both demographically and politically, and this is why we can expect travel between Los Angeles and San Francisco or between New York and Washington to be much more symmetric than in France or the UK.
Pedestrian Observations from Vancouver: Street Width and Building Height
I moved to Vancouver last weekend. The slow pace of posting will probably continue for another week, but I do have multiple posts in the pipeline. I am currently at a downtown hotel, commuting to Kitsilano to look at apartments and to UBC to deal with early paperwork.
My appreciation of Translink dropped within a day, after I discovered that discounted books of multiple tickets and monthly passes are only available at 7-11 and other convenience stores, rather than at stations. (The ticket machines offer what appeared to be multiple-ride tickets but turned out to be single-ride tickets, perhaps usable by multiple people at once.) I still think it’s better-run than the other transit agencies of North America, but it has a lot to learn from New York regarding how to make fare media usable by passengers.
The most surprising pedestrian experience I’ve had is about the street width. The streets are wide, which is what I expected, based on Jarrett’s paean to the grid at Human Transit (which is necessarily wide in North America). What I did not expect was that the buildings would be so short away from downtown. Jarrett’s description of Central Broadway, around the Canada Line stop, as the second downtown, made me think Broadway was a continuous corridor of high-intensity development. It is not; it feels more like a secondary retail strip. The commercial buildings are usually one- or two-story, with some clusters of higher density at major street intersections, especially Cambie but also Granville, MacDonald, and others. This development is more spiky than linear, as if there’s already rapid transit on the route, rather than just interlined high-frequency buses.
Away from Broadway, Kitsilano feels very suburban – at least, the part of 11th Avenue I walked on does. The density looks higher than in Providence because a few of the buildings are tall, but most of the buildings have ornamental front lawns, and the sidewalks are narrow paths through the grass, more like a suburb than like the very old New England neighborhoods I had gotten used to over the past year.
There’s a point I made early on in this blog – I can’t remember where – about the relationship between street width and building height. To be pedestrian-friendly, a street needs to have a certain proportion between the height of the street wall – for example, the height of the buildings flanking it if they do not taper toward the top – and the width of the street. The ratio I initially proposed is 1:1, with a favorable range of 1:2 to 2:1; nowadays I’d propose higher ratios – Providence’s East Side’s 1:2 feels a bit too low, while the 2:1-3:1 on old streets in Boston and Providence feels fine – but the principle is similar.
Downtown Vancouver has what feels to me like correct proportions. With the setbacks and the tapering buildings, the height-to-width ratio is kept to average levels, with modernist skyscrapers balancing wide streets. Because there is high density in the core, the streets do not feel desolate, and the major streets are flush with ground-level retail. Buildings that look very similar to Akirov Towers do not make me feel the same revulsion toward their design; Akirov Towers are built like any housing project, but the towers of Downtown Vancouver feel like New York’s towers on a base. Although many of those buildings do not actually have any street wall, enough of them do that I feel like I’m walking in a human city.
Broadway does not have the same feel. From the bus, the trees frame the street, making it feel less like a highway. On foot, it’s different, and it feels more open and less dense. It works well enough for transit – the bus lines on it have extremely high traffic, much of it due to the pull of UBC – but the pedestrian experience is less than perfect. The street is 30 meters wide, the same as a Manhattan avenue or two-way street, and it needs to be framed by buildings about that tall.
UBC is the worst. Granted, it is summertime, so it’s more deserted than it is during the year. But Harvard Square, Kendall Square, College Hill, Morningside Heights, and even Yale are teeming with people at all times of year. UBC clearly has people – they fill the buses to the rest of the city – but the campus is so spread out there aren’t that many of them at one spot (or if there are, I haven’t found it). There is one cluster of restaurants at University Village, and a few cafes and other retail outlets sporadically located elsewhere, but nothing truly mixed-use the way any of the aforementioned Northeastern college neighborhoods are. There is a grid of major campus boulevards, built with landscaped lawns, but they end up feeling like a large urban renewal project. Columbia has some of those, but they have more people using them; the only Northeastern school I know that has similarly lonely throughfares is MIT, but MIT has its livelier parts at the main administration building and near its subway stop.
Somewhat away from the grid is UBC’s bus loop terminal. My first experience at UBC was stepping off the 99-B express bus to a terminal with a few bays for buses, surrounded by parking, and landscaped lawns that are far prettier from a moving vehicle than on foot. According to a presentation about the proposed subway under Broadway, UBC’s mode split among non-Vancouver residents is 71-27 in favor of cars. (Central Broadway’s is 77-21, which surprised me since it looks not particularly dense but not really auto-oriented the way UBC is). For Downtown, the comparable figure is 49-49.
Despite all this, Vancouver is by North American standards a reasonably successful transit city. Its transit usage is okay, and unlike in most North American cities, it is growing, if not as fast as I’d like. Translink believes that a Broadway subway would get 146,000 daily riders, up from 60,000 on the 99-B plus about 50,000 on local buses today; intuitively this feels low to me, though achieving high enough transit mode share to UBC and Central Broadway would probably require more fundamental changes to their urban design than is politically acceptable. For one, local activists would have to stop referring to the few mid-rises amidst the two-story retail at Broadway and Cambie as high-rise or high-intensity development. It’s nothing upzoning won’t fix, but upzoning this intense is unlikely. It’s really too bad, because walking on Broadway I feel insufficient height is the only problem on the street.
The Urban Geography of Park-and-Rides
The urban geography of transit cities and of car cities is relatively well-understood. In a transit city, there will be a strong CBD surrounded by residences with spiky secondary centers, all quite small geographically but dense, centered around train stations and junctions; because density is high throughout, minor trips are done on foot. In a car city, all trips are done by car, the core is weak, and most employment is in suburban edge cities and edgeless cities.
What I haven’t seen is an explanation of how urban geography works in mixed metro areas: there are those in which short trips are done on foot and long ones in cars, such as new urbanist developments, and those in which short trips are done by car and long ones on transit, such as park-and-ride-oriented commuter suburbs. It is the latter that I want to address in this post.
The first feature of park-and-rides is that of all combinations of modes of transportation, they are the fastest and enable suburbs to sprout the farthest from the center. This is because the segment of the trip done in a car is uncongested and so driving is faster than transit, while the segment done on a train parallels a congested road, and conversely makes few stops so that average speeds are high.
On top of this, because intra-suburban trips are done by car, the density in the suburbs is very low, comparable to proper car cities (see the lower end of the density profiles of the New York, Chicago, and Boston metro areas), and this forces sprawl to go outward. New York is the world’s most sprawling city measured in total built-up area; the only other city of comparable size that’s not a transit city or a bus/jitney city is Los Angeles, which is forced to have denser suburbs because of the mountains. Of course Houston and Dallas sprawl even more relative to size, but because they lack New York’s transit-oriented core, there’s an inherent limit to their size.
The other feature is that there’s a definite socioeconomic history to the development of the auto-oriented commuter suburbs of transit cities. First, people move to the suburbs and commute into the city, almost always by train due to road congestion (or, as in the earliest New York suburbs, because mass motorization hasn’t arrived yet). The mass exodus into these suburbs comes from cars rather than commuter rail, and so the local services for people living in those suburbs are built at automobile scale, rather than at the walkable town center scale of 1910.
In North America there’s also a definite class element here – the early movers are the rich rather than the poor. Historically this was partly because poor people couldn’t afford regular train fare, and partly because the impetus for suburbanization was idyllic country homes with access to urban jobs rather than cheap housing for the poor. If I’m not mistaken, this wasn’t the case in Australian cities’ suburbanization, leading to a more urban transit-style mode of running mainline rail. The result of this class distinction is that North American commuter rail styles itself as for the rich: agencies make an effort to ensure everyone has a seat and downplay comfortable standing space, and the expectation is that transit is a last-ditch mode of transportation for when cars just don’t have the capacity to get people downtown, and so nobody needs to take the trains in the off-peak or take a bus to the train.
The result is that the park-and-ride city will still have a strong core with high-capacity transportation, and the primary CBD will maintain its supremacy for high-income jobs. Establishing edge cities in the direction of the favored quarter can happen, but there’s still a congested city nearby, and so from many directions it’s impossible to drive, and taking transit is impossible. Thus jobs in White Plains and Stamford are not nearly as high-paying as jobs in Manhattan.
There can even be secondary CBDs, if the inner part of the metro area, where people take transit more regularly than the suburban commuters do, is large enough. But those secondary CBDs are frequently quite auto-oriented. Brooklyn’s mode share for jobs is only 42-39 in favor of transit (for residents, it’s 60-25), and all other counties in the New York region except Manhattan have more workers driving than taking transit, a situation that is not true if one looks at residents. Those secondary CBDs then have mixed characteristics: they are dense and fairly walkable, as can be expected based on their history and location, but also have plentiful parking and a large share of drivers demanding even more. They can accommodate multiple modes of transportation, but driving is more convenient, and from the suburbs the commuter rail system isn’t always geared to serve them.
