Learning from TTI

Mon, 11/16/2009 - 14:22

This week, I finally got around to looking at the latest (2009) Texas Transportation Institute study on traffic congestion. (1)

Two facts struck me as interesting.  First, the great congestion surge of the past decade or two is over.  In most large metropolitan areas, congestion (measured as hours lost to congestion per traveler) peaked around 2005, and actually declined in 2005-07.  For example, in Atlanta, hours lost to congestion peaked at 61, and decreased to 57 by 2007.  Congestion increased in only three of the fourteen largest regions (Washington, Detroit and Houston)- and in each of these by only one hour per traveler.

Public Options in Transit and Health Care

Thu, 11/05/2009 - 10:15

Over the next few months, Congress will continue to debate health insurance reform, and in particular, whether to create a "public option"- a government-financed insurance company which would compete with private
health insurers.  Opponents of the public option fear that the government package might drive private insurers out of business. Are such concerns legitimate? American transportation history may give ammunition to both supporters and opponents of the public option.

How to drive traffic away

Mon, 10/19/2009 - 10:08

A few days ago, I was trying to take a streetcar in Toronto- and the streetcar was just as congested as any suburban arterial. The lines in front of streetcars were so long that I couldn't get into the first streetcar. Or the second. Or the third. Instead, I had to wait a few minutes (horrors!) for the fourth streetcar.

I asked myself: what if streetcars only ran every hour, instead of every few minutes? Would the streetcars be equally crowded? Of course not. People would abandon the streetcars and start to use cars (if they owned them) and buy them (if they did not yet own them).

The Genesis of Stalemate

Tue, 10/13/2009 - 09:28

Some of my acquaintances believe that climate change may end human life (or at least civilization) and that the only way to save humanity is to massively reduce economic growth and consumption. Other acquaintances believe that climate change is, if not an outright hoax, a minor problem- and that even the slightest attempt to regulate emission-creating industries will itself destroy American civilization.

A Middle Ground In The Bag Wars

Thu, 09/24/2009 - 12:01

The San Jose City Council is considering a proposal to ban plastic bags and most paper bags in supermarkets, out of concerns about the greenhouse gases used to manufacture them and about the waste from discarded bags.  But this policy might create as many environmental problems as it solves. 

In a city without disposable bags, shoppers who seek to buy large amounts of groceries will have to drag around an army of nondisposable containers.  For drivers, this is not a big deal.  Susie SUV can always find  space for dozens of nondisposable bags in her truck.  And because Susie’s bags can stay in her truck forever, she will always be able to make impulse purchases without difficulty.

Stress and the city, part 2

Mon, 09/14/2009 - 10:53

Not long ago, I posted on what makes some cities more stressful than others. (See http://www.planetizen.com/node/40441 ). In that post, I remarked that the ideal objective indicia of stress (resident surveys on crime, illness, etc.) often do not exist for most cities.

What Makes A City Stressful?

Wed, 09/02/2009 - 08:58

Forbes just came up with another of its “Most X City” surveys. This week, it listed the most stressful cities (http://www.forbes.com/2009/08/20/stress-unemployment-homes-lifestyle-rea... ). Nearly all of Forbes’ criteria, however, are silly in one respect or another.

Legibility vs. efficiency

Wed, 08/26/2009 - 08:59

One reason why buses are less popular than trains is buses' lack of "legibility": the ability of an occasional passenger to figure out how to get somewhere by bus. While subway or light rail passengers can look at a system map (which is usually present on a station wall) and figure out that a train to destination X shall arrive at their station reasonably soon, bus passengers typically have to invest time in getting schedules, and then pray that the schedule has not changed.

New urbanists and old-fashioned Jews

Mon, 08/17/2009 - 16:40

A few years ago, someone asked me the following question (loosely paraphrased) on a listserv: “Since the most tradition-minded* religious Jews are required by Jewish law to walk to synagogue on Sabbaths and holy days (and thus presumably prize walkability) why aren’t they a major market for new urbanist developments?” At the time, I didn’t have a coherent answer. But now that I know more about both traditional Jews and new urbanism, I do.

Geography Still Matters

Mon, 08/10/2009 - 08:01
 

Some commentators think that Internet technology will liberate us from the constraints of place; for example, one amazon.com book review of Joel Kotkin’s The New Geography states “Because today's connected workers can live anywhere they want, they will live anywhere they want.”  Kotkin himself is a little more circumspect, but writes: “Telecommunication allows people who want privacy, low-density neighborhoods and good schools to live in small towns in a way never before possible.”(1)  There is a tiny amount of truth to this claim: the Internet does make it

A Fable About Sprawl

Mon, 07/20/2009 - 14:32

Once upon a time, there was a city called City. And everyone living in City voted in the same elections and paid taxes to the same government.

And then 5 percent of the people decided that they wanted to live in an new neighborhood that was opened up for development by the highways. And they called it Richburb, because they were, if not rich, at least a little richer than many of the people in the city (since even if there wasn’t zoning to keep the poor out, new housing usually costs more than old housing anyhow).

Urbanism, Suburbs and Families: They Can All Go Together

Tue, 07/07/2009 - 16:09

A few weeks ago, I read an online comment suggesting that unnamed "planners" displayed no interest in suburbia, single-family housing or family life, and instead are only interested in improving downtown neighborhoods for single people. If by "planners" the author of this comment meant new urbanists or critics of the sprawl status quo, this claim is simply incorrect.

Over the past month, I have visited half a dozen new urbanist developments in Dallas and Denver (1). All of these developments have a few things in common: all include both retail and residential uses, and all strive for walkability by providing sidewalks and narrow, gridded streets. But the developments differ in two other respects: geography and housing type.

Judaism and Urbanism

Mon, 06/22/2009 - 12:22

After visiting Denver for the Congress for New Urbanism (CNU) conference, I began to meditate on the relationship between Judaism and urbanism, and on how few cities accommodate both. In particular, I was impressed by how well-populated downtown Denver was compared to the southern cities where I have spent the past three years (Jacksonville) and this summer (Little Rock) - but I stll couldn’t imagine myself living in downtown Denver all that comfortably.

How walkable is it?

Sun, 06/14/2009 - 07:24
 

Recently, an acquaintance asked me how to measure the walkability of a place he was visiting.  

I could have told him to just look at Walkscore (www.walkscore.com).  Walkscore assigns scores to places based on their proximity to a wide variety of destinations.  So if a place has a high walkscore AND a walkable street design (e.g. narrow streets, a grid system, etc.) it is probably pretty walkable.

Walkable vs. Unwalkable Airports

Tue, 06/02/2009 - 08:46

I’ve read some airport-related planning literature about the interiors of airports and about their public transit connections. (For a good example of the latter, see http://www.planetizen.com/node/34842 ) But one other difference between airports relates to their exteriors: the difference between walkable airports and not-so-walkable airports.

When Spillover Parking Isn't So Bad

Wed, 05/20/2009 - 04:37

One justification for municipal minimum parking requirements is the danger of “spillover parking”: the fear that if Big Brother does not force businesses to build huge parking lots, that business’s customers will “spill over” into neighboring businesses or residential neighborhoods, thus reducing the parking available to the latter group.  For example, if Wal-Mart doesn’t build a thousand parking spaces, maybe Wal-Mart’s customers will park at Mom’n’Pop Groceries down the street, thus reducing the parking available to Mom’n’Pop customers.

Congestion, Pollution and Freeways

Wed, 05/06/2009 - 20:23
A common argument in favor of building sprawl-generating roads and highways is that if we just pave over enough of the United States, we can actually reduce pollution and greenhouse gas emissions by reducing congestion.  For example, a Reason Foundation press release cited a report by two University of California/Riverside engineering professors, “Real-World CO2 Impact of Traffic Congestion” (available online at http://www.cert.ucr.edu/research/pubs/TRB-08-2860-revised.pdf ).    But if you read the report carefully, its policy impact is a bit more ambiguous.

The Takings Muddle: A Brief Guide

Mon, 04/13/2009 - 10:04

The Takings Clause of the Fifth Amendment provides that government may not take private property without just compensation. The courts have held that this clause requires government to compensate landowners for losses caused by government regulation in certain situations- most notably when regulation leads to a permanent physical invasion of property (1) or makes property worthless (2).

A Pig In A Parlor

Mon, 03/23/2009 - 19:46

The state of Virginia’s decision to limit the use of cul-de-sacs in residential subdivisions(1) will no doubt create a torrent of commentary, both pro and con.  In the residential context, cul-de-sacs do have certain advantages: they limit traffic near homes, thus allegedly creating quieter environments for homeowners.    So perhaps there is a case for the residential cul-de-sac.

But in a commercial setting, the cul-de-sac may be the "right thing in the wrong place--such as a pig in a parlor instead of a barnyard.”(2)   In such settings, the cul-de-sac has the same disadvantages as the residential cul-de-sac, with few of the advantages.

One Way To Save Transit

Wed, 02/25/2009 - 13:56

In much of the United States, day-to-day transit service is under assault as never before; state and local treasuries have been depleted by the recession, and the federal stimulus package is unlikely to be helpful because federal dollars are more likely to flow into capital programs (English translation: shiny new railcars) than into preserving existing service (1). Thus, Americans will have the worst of both worlds: billions thrown at transportation while existing bus routes get whittled away.
