scope:

Traditional interchange design usually does not provide adequate and safe accommodations for pedestrians and bicyclists. As a result, interchanges currently constitute signi? cant barriers to increasing the walk and bike mode shares in transportation networks. In response to these challenges, the Pedestrian and Bicycle Council (PBC) initiated a series of interactive workshops over three years to discuss interchange design issues and opportunities with regard to pedestrian and bicyclist safety and accommodation. The PBC and the Traffic Engineering Council co-sponsored these workshops, which focused on traditional on-ramps and off -ramps, and single-point urban interchanges as representative of recent innovations in inter-change design that present particular challenges for pedestrians and bicyclists. This report compiles design guidelines for improving safety and accessibility for pedestrians and bicyclists at interchanges. A number of design case studies and their recommended treatments are then developed in compliance with the design guidelines
