I have generally been pretty skeptical of speed bumps (also known as "speed humps"); they can be harmful to cars, but don't do as much to calm traffic as some other techniques.

Generally, supporters of a less car-dependent society are critical of one-way streets, while supporters of the sprawl status quo favor them. 

But I have a somewhat different perspective after driving around downtown Atlanta today.  I drove there to do an errand for my mother, and the maze of one-way streets added 10 minutes to my drive time, as I searched in vain for a southbound street to get me home.  So it seems to me that one-way streets are actually inconvenient for someone who has business downtown and is trying to navigate his or her way home.

One common myth about American sprawl is that it is somehow related to Americans' support for homeownership.  But in fact, Americans are more likely to rent than residents of many other countries: 33 percent of us do so, as opposed to 26 percent of EU residents, 22 percent of New Zealanders, and 30 percent of Australians and British.  (Denmark's rental rate is about the same as ours).

Last week, I had a conversation with a faculty colleague about densification in Manhattan.  He said he visited Philadelphia, and he liked Philadelphia better because it wasn't so crowded.  

But I responded that Manhattan wasn't as crowded as he thought it was.  To be sure, there are a few places in Manhattan (especially at certain times) that are very crowded indeed- in particular, the blocks closest to Penn Station.  When I get off a train and get into the station during rush hour, I am met by the New York stereotype- a sea of people.

Because much of the literature on anti-density "exclusionary zoning" involves suburbs, you might think that cities tend to favor development and density.  But according to a recent paper by Vicki Been of NYU Law, this is not the case.  The study examines rezonings proposed by the New York Department of City Planning, and shows that the city downzones property more often than it upzones. 

I recently read a blog post explaining that smart growth and urban infill are not so smart because it forces poor people into suburbia.  The logic behind this claim is, as far as I can tell, as follows: 1) infill means rising real estate values in cities, (2) rising real estate values means people can't afford to live there, and (3) therefore smart growth shunts the poor into suburbs.

I just saw the Brookings report on job sprawl- the movement of jobs to exurbs.  Do some metros have more job sprawl than others?  If so what correlates with it?

In new urbanist circles, "cheap" is often a dirty word; for example, I recently noticed a reference to "cheap" suburbs in a blog.  I find this objectionable for two reasons.  First, in a nation where many regions suffer from insanely expensive housing projects, we should be striving for cheaper housing.  To be fair, sometimes planners and architects use "cheap" as a synonym for "badly designed"- but this is imprecise.  If we want to say something is badly designed, we should say exactly that.

Numerous studies (such as the one referenced here) have suggested that there is some connection between sprawl and obesity, because residents of sprawl walk less and are thus more likely to weigh more.
