In a project funded by the The District Department of Transportation (DDOT), Portland State University is partnering with the University of North Carolina at Chapel Hill to document and identify factors associated with road user safety and comfort at intersections with permanent versus tactical (both with and without mural art) curb extensions, as well as a set of control locations with no curb extensions. DDOT has over the last few years installed several curb extension treatments on different intersections throughout the city. While DDOT has anecdotally heard that these treatments are appreciated by impacted communities, more evaluation is needed to determine the actual impacts on safety and comfort for pedestrians who cross at these locations. In this study, the research team will partner with DDOT staff to collect survey data and video data that will then be used to measure these impacts for pedestrians. Specifically, this project will focus on permanent curb extensions, tactical curb extensions, and painted mural curb extensions. Results will be compared to non-treated locations to help DDOT distill guidance about crossing treatments.
