Proposal for a Before and After Impact Assessment of the Forbes Avenue Reconfiguration Project

Reduction in urban motorist lanes has grown in popularity in recent years in an effort to reduce collisions and accommodate increased desire for active transportation. While these projects have been innovative and popular, there isn't yet a strong consensus on whether these projects deliver on their promised benefits, with a common problem being a lack of sufficient before and after data collection to show the effects. The research team focuses on the upcoming Forbes Avenue reconstruction project that will occur along the north edge of campus (yet with the completion of the new Tepper quad in several years will cut through the center of an emerging campus footprint). This project is a prototype of a 'smart mobility' implementation, involving new technology, multiple modes and measures to improve bike, pedestrian and vehicle safety, and will be funded by the Pennsylvania Department of Transportation, Southwestern Pennsylvania Commission, and CMU. The team proposes a multi-criteria 'before and after' impact assessment. Major aspects to be assessed include: Changes to vehicular volumes, speeds, travel times and emissions; Changes in public transit routing, frequency, and ridership; Changes in use or demand for on-campus and near-campus parking; Changes to bike and pedestrian use of Forbes Avenue; Perceptions of safety, accessibility and aesthetics for Forbes Avenue; and Changes in local traffic noise. The team has already archived significant amounts of 'before' data on Forbes Avenue and will be gathering more by deploying a network of various air, audio, video, and related sensors along Forbes Ave. SPC is interested in this assessment as a means of calibrating their project selection criteria. The team believes the City of Pittsburgh and PennDOT are also interested in a comprehensive assessment. The team expects to end with several professional papers and a policy maker's guide describing this smart mobility project's impacts and provides a basis for other such projects.
