Replay: Counterintuitive trues about urban transport

Enrique Peñalosa (former mayor of Bogotá) presented a pleasant lecture at LSE titled: Politics, Power, CitiesListen to podcast here (approx 91 min).

Here are some interesting snippets (They might look obvious to some of you. But do they look obvious to you mayor?)

  • What creates traffic is not the number of cars, is the number of trips and the length of trips.
  • Mobility and Traffic Jams are total different problems that require different solutions. Reducing car use is different than solving Traffic Jams.
  • To solve Traffic Jams is, in fact, to facilitate car use.
  • The only way to solve Mobility is with public transport. This will solve Mobility but not Traffic Jams.
  • The only way to solve Traffic Jams is restricting car use. And the most obvious way to restrict car us is restrict parking.
  • To park is not a Constitutional right anywhere.
  • For public transport the most important thing is Density.

*ps. I agree with these statements ("counterintuitive trues" as said Peñalosa). And I don't think they contradict the ideia of polycentric cities.

*ps2. He didn't say much (nothing) about land use... I missed that.

The creation of Municipalities in Brazil

The creation of municipalities in Brazil from 1872 to 2010 (written in Portuguese only…sorry...). Thanks Ernesto and Leo for the tip. How to overcome this issue for historical analysis? One possible answer is here.

2011 Global MetroMonitor

The Brookings Institute recently released their 2011 Global MetroMonitor, which analyses the economic growth in the world’s 200 largest metropolitan economies (including five Brazilian metropolitan areas).

It looks pretty interesting. For instance, "ninety percent of the fastest-growing metropolitan economies among the 200 largest worldwide were located outside North America and Western Europe". More here and here

Assorted links on Congestion

[image credit: Jacob]

  1. Congestion costs in Australia

  2. Braess paradox: “Put simply, the paradox ... says that adding a new road to a transportation network, rather than making things batter, may actually slow things down for all its users” (Vanderbilt in Traffic). We have just presented a working paper at the 8th Space Syntax Symposium that analyses the relationship between street-network connectivity and travel time variability. Well, It's jus a working paper but the results suggest that the Braess paradox should be the exception.

  3. The Case for Congestion Pricing

  4. "Congestion is a bit like cholesterol - if you don’t have any, you die"

  5. The Brazilian government has just signed a federal law that gives municipalities the legal support to implement congestion pricing schemes (revenue must be provided to public transportation) -  written in Portuguese only.

Traffic - Why we drive the way we do and....



I've read this book last year, but finally I stopped procrastinating   got time to write a post about it.

It's a really  interesting book, full of curiosities about traffic bevaiour flirting with sociology and economics. Here is the NYT's review



I selected four quotes that I would like to use as an epigraph:

  1. "The problem, as is so often the case in traffic, is that the collective result of everyone’s smart behavior begins to seem, on a larger scale, stupid" p.149

  2. “Traffic patterns are the desire lines of our everyday lives. They show us who we are and where we are going” p. 151

  3. "Traffic is thus a living laboratory of human interaction, a place thriving with subtle displays of implied power. When a light turns green at an intersection, for example, and the car ahead of another driver has not moved, there is some chance that a horn will be sounded. But when that horn will be sounded, for how long and how many times it will be sounded, who will be sounding the horn, and who the horn will be sounded at are not entirely random variables." p.34

  4. "If you look at trip rates by male versus female, and look at that by size of family…the women’s trip rates vary tremendously by size of family. Men’s trip rates look as if they didn’t even know they had a family. The men’s trip rates are almost independent of family size. What it obviously says is that the mother’s the one doing all the hauling." p.135
