Formal Announcement

Those of you following my Twitter feed already know this: I’m moving to Vancouver sometime in this summer for a two-year position at UBC. Expect a dramatic reduction in the number of posts expressing exasperation with local transit planning beginning sometime in July or so. I will try to keep writing about the Northeast and not just about Vancouver.

Quick Note: No More Track Maps

I regret to say that I’ve taken down the track maps by Rich E Green that I’d hosted, in accordance with requests by him and by his employer, to whom he sold the maps. This involves breaking past links; I will put notices in past posts of mine that link to them, including a brief description to what is seen in the maps when necessary, and I encourage others to do the same.

Categories

I’ve just added categories to this blog, due to what appears to be popular demand. I saw too many hits coming from people who Googled key phrases together with the name of this blog, which suggests the blog itself needs a better internal search; here it is. I’ll add more categories if there’s demand, especially cities or regions I revisit.

On another note, if anyone knows how to lift the comment moderation rule that holds up every comment with more than one link, please let me know. Since everyone’s first comment is held anyway, and so far I’ve had no spam sneak past the filter, this rule is redundant.

Where Did You Grow Up?

The last few weeks’ posts on Old Urbanist made me think about what urban forms people prefer, and how it’s affected by what they are familiar with. Rather than speculate on what people in my social circle prefer, I yield the stage to you. What type of urban environment did you grow up in, and/or influenced your thinking about cities the most? And what form of urban development do you find most desirable?

I’ll start: I grew up in the Old North of Tel Aviv, a dense (about 15,000/km^2) neighborhood whose residential stock is almost exclusively four-story Garden City apartment buildings. Buildings are not attached as rowhouses, but instead are set back a few meters from the edges of the lots; typical apartment size is 120 square meters. The neighborhood is upper middle class – indeed, North Tel Aviv is used as a metonym for latte liberalism – but is not uniformly so. Growing up, I knew plenty of people in the neighborhood who were middle middle class, a few who were working class, and a few who were outright rich. This somewhat distinguishes North Tel Aviv from some surrounding suburbs that are nominally equally rich but are more uniformly upper middle class. In the 1990s, it was also stable rather than gentrified; there were, and still are, people living in the same neighborhood, sometimes the same apartment, for multiple decades.

As a result, I never grew up with the association of detached houses with wealth. Hebrew even distinguishes words for houses in general (house/home) and words that denote wealth (villa, cottage) but has just one word normally for an apartment; English, which distinguishes an apartment or a tenement from a condo, is exactly the opposite. Having a car is important for social status in Israel, but the idea is to drive it a short distance to work, as my parents did. Driving 20 kilometers each way would be strange. At the same time, I took some measure of walkability for granted, making me uncomfortable with sections of the city that were built after the 1950s and were designed to automobile scale. I did not think of public transportation as a normal means of getting to work, unless one couldn’t afford a car, but it was nifty for getting to school.

The ideas about urbanism I’ve developed out of that experience, followed by Manhattan, are:

1. Street width should be close to building height; for the purposes of this discussion, street width is measured from building edge to building edge, and building height is the average height of the continuous street wall. A height:width ratio of about 1 or slightly higher is best. Below about 1/2, it’s too open; in Providence, where the ratio is about 0.6, measured from the top of buildings, I already walk in the middle of the roadway, as if the streets were naked. Above about 2, which exists on some streets in such pre-industrial cities as Florence, it feels like an alley. As a corollary, very narrow streets are suitable for low-traffic cities, whereas high-density places should look more like Manhattan.

2. Every normal neighborhood amenity should be reachable on foot, on streets that are designed to be used primarily by pedestrians. If you need to take mechanized transportation or cross a highway to get to the supermarket, there is something wrong with your neighborhood.

3. Bicycles are a form of private transportation.

4. Stoplight phasing is critical.

5. The street network should be porous. The closer to a regular grid, the better. The Old North has a grid of arterial streets, but the local streets terminate in T-shaped intersections, like this, and it’s not always possible to tell a local from an arterial street on sight; in addition, the grid is not really continued into other neighborhoods, making walking there confusing. I found Manhattan much more walkable than the Old North for this reason.

I will now exit the stage and make this an open mic.

Hi

I’ve been meaning to do an official introduction, but then had content posts to write. So here goes: I have just obtained a Ph.D. in pure mathematics from Columbia, and will move to Providence sometime this summer. My research has nothing to do with transit or other social or political issues, but living in New York I gradually picked up an interest in transit. I’ve always been interested in walkable cities, and fell in love with the Manhattan grid even as a tourist.

Although I have a pedestrian perspective, in practice most of what I write about is technical transit issues. I don’t intend for this blog to be the Systemic Failure or Caltrain-HSR Compatibility Blog of the Northeast, but I do share their perspective and analysis. It does not mean supporting a technocracy, but it does mean looking skeptically at projects and future plans.

For many years, even before my previous blog, I was skeptical of American exceptionalism, and often looked abroad for guidance. This is true for transit, too. Discovering how much higher American construction costs are than European ones was one of the forces galvanizing my distrust of American agencies; if they build subways for so much more than peer cities, then why take their studies at their word?

Before living in New York, I lived in Tel Aviv and Singapore. Singapore is transit-oriented, but for pedestrians it’s cul-de-sac hell. Tel Aviv is partly walkable, but the haphazard street network would always make me get lost outside my own neighborhood. My parents live in the Riviera, which has small very walkable patches surrounded by sprawl. If I mention one of those three regions as a comparison base, chances are it’s personal experience, whereas if I mention other cities, chances are it’s a case study.
