Evaluation of Different Curb Extension Treatments for Pedestrian Comfort and Safety at Intersections

The District Department of Transportation (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.
