Streetfilms' Clarence Eckerson recently visited London to learn about ways transportation planners in the Big Smoke are re-envisioning their city's streets to put people over cars. In the Borough of Lambeth, Eckerson found "modal filters" where planners have effectively created small town squares by diverting traffic at intersections. The design enhanced safety for cyclists and pedestrians while opening up more space for outdoor dining and bio-swales.
