Heffron Transportation led the transportation policy work for this project, which was a joint effort between the City of Seattle's Department of Planning and Development (DPD) and King County Metro. The purpose of the project was to develop new tools to reduce single-occupant-vehicle (SOV) travel into the downtown area of the City. For this work, the team developed the City's new Transit-Friendly Design Guidelines and strategized means to integrate them into the City's processes. Heffron Transportation also crafted a new Director's Rule for Transportation Management Plans (TMP), intended to entice developers to incorporate TMP elements earlier in the project planning. The firm also helped developed the training program for these new resources.
