Counterintuitive trues about urban transport

Enrique Peñalosa (former mayor of Bogotá) presented a pleasant lecture at LSE titled: “Politics, Power, Cities”. Listen 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.
