This project will identify potential changes to WSDOT’s design processes that will more effectively support agency staff in making performance-based decisions about the design and installation of multimodal improvements. For this study, the concept of multimodal will include active transportation (pedestrians, bicycles), freight, and transit, as well as single occupancy vehicles. Looking at previous projects, the researchers will systematically evaluate the extent to which project engineers have been able to define project goals that encompass multimodal transportation objectives. They will then evaluate the extent to which projects with multimodal objectives have employed performance indicators in the project justification; whether multimodal features have been incorporated into the projects considered; and whether, how, and what kind of performance measures have played a role in design decisions. On the basis of this information and a literature review of best practices, the researchers will develop updated or new guidance for WSDOT planners and designers on increasing the use of multimodal performance indicators in their decision-making processes.
