Travel Impacts of a Complete Street Project in a Mixed Urban Corridor

Complete streets facilitate multi-modal travel through human-centric infrastructure design with goals of improving safety and accessibility for all potential travelers. Examples include designing corridors with wide sidewalks, lighting, street furniture, adding bike lanes, improving transit shelters and turnouts, among others. This study evaluates the travel impacts resulting from a complete street redesign project through an urban corridor in Pittsburgh, Pennsylvania. The retrofit project involved reducing vehicle lanes from four (two lanes in each direction) to three (one lane in each direction with a center turn lane) and adding dedicated bike lanes in each direction. The project also included new traffic signals, one new pedestrian crossing, reconfiguration and relocation of several intersections, improved bus turnouts, new pavement, and new street furniture. Before-and-after travel impacts (traffic counts and speeds, transit ridership, bicycle counts, air quality, and crash counts) were evaluated to quantify total benefits resulting from the retrofit project.
