Trawling through some real estate brokerage sites, typically in fairly dense small towns and pre-war suburbs, a refrain keeps catching my eye: “Leave your car in the garage.” The listing will then note the proximity to trains, schools, etc. I’m not sure who first came up with this rallying cry — and based on what I’ve seen in some of these towns (pedestrians being mostly people moving to and from their cars) I wonder if it might be more real-estate bluster than anything else — i.e., the potential of walking is there, as is the potential for the great room to be great and the massive chef’s kitchen to produce fare worthy of Grant Achatz, but in the end this potential gives way to some real or imagined vehicular reality (I need to get groceries, it’s just easier). But I can’t say I’ve ever seen a real estate ad that promised: “Take your car out of the garage, often!”

I found myself on the carerra septima this afternoon in Bogotá just shy of 5 p.m. (having just consumed a wonderful dish of la posta negra de Cartagena at the Club Colombia, watched the Netherlands defeat Uruguay, and had a cup of tea from coca leaves to counter the effects of altitude sickness — it seemed to do the trick). In any case Carerra 7 is one of the city’s principle arteries, multiple lanes divided by an island. At 5 p.m., though, something curious happens on this street: It turns into a massive one-way boulevard out of the city, and towards the north. This is an old and much-discussed idea — contraflow lanes — one that was practiced briefly in cities like Los Angeles and made a splash recently in emergency management circles for mass disaster evacuations.

But it was striking to see it in action. At just the stroke of 5 our car was still on 7, and there was already a small stream of vehicles beginning to seep across from the other lane. Their movement was cautious, exploratory, with the first vehicles coming across employing their hazard flashers. Their numbers began to surge, and it was immediately evident that staying on 7 was not prudent. There were one or two traffic police scattered about, and there are signs advising of the change, but one got the sense this was just a bit of ingrained civic behavior, as routine as the clock itself.

I’m wondering if the new development pattern in the Lakewood scheme is having any effects on transportation (i.e., what’s the VMT of people living in Belmar versus others)? And on the subject don’t miss the National Academies podcast (and paper), “Driving and the Built Environment.”

The conclusion of the study is that being a Catholic country or not seems to be as important as being a wealthy country or not. Being a non-wealthy Catholic country leads to more traffic and hence more motor vehicle accident deaths than being a wealthy Catholic country. Being a wealthy Catholic country, however, does seem to lead to more previous traffic term accidents than being a wealthy non-Catholic country.

That’s from: K. Melinder, “Socio-cultural characteristics of high versus low risk societies regarding road traffic safety,” (2007) Safety Science, 45 (3), pp. 397-414.

Over at KCRW’s Design and Architecture, Francis Anderton considers a part of the built environment often overlooked in transportation questions: Shade. It is remarked that trees in Los Angeles are placed to provide shade for cars, not people walking on sidewalks.

From an interesting post at CSV, via Marginal Revolution:

This phenomenon, where improved safety spurs on greater risk taking, is known as risk compensation, or “risk homeostasis”. Most of us became familiar with the concept from debates over anti-lock brakes (ABS), but its specter has plagued nearly every attempt to improve automotive safety, from seat belts to night vision. Yet almost nothing about risk compensation - its etiology, its prevalence, its significance - is certain.

To prove the phenomenon even exists, one particularly inspired British researcher had volunteers ride bicycles on a closed course, with half the people wearing helmets and proper attire, and the other half clad in their underwear. Graduate students positioned on the sidelines graded the volunteers performance and tallied any unsafe maneuvers. The results showed that the unclothed group practiced much safer driving habits, thereby supporting risk compensation theory - and Britain’s reputation for eccentricity.”
