"Traffic planners say Westerley residents aren't the only ones driving short distances -- and adding to the region's notorious traffic congestion -- because walking and riding bicycles are not safe options... Reducing traffic by getting more people out of their cars is often as simple as building a sidewalk, painting a crosswalk, installing better streetlights or paving a bike path. All of them are relatively quick to do and cost little compared with widening roads, adding Metro lines or building more Metro parking garages."
