Another week, another look at traffic. It's not Spiderman 3, but Contested Streets is a new documentary premiering on Tuesday at the IFC Center that offers a history of traffic in New York and examines things like (gasp) congestion pricing in London and Paris' Bus Rapid Transit. The film is co-produced by Transportation Alternatives, which brings us goodies like the Parking Spot Squat. They're happy to help you set up a group screening at home. We predict it will be the summer box office favorite of urban policy types everywhere.
