Safe-D: Safety through Disruption

Curb Management Practices and Effectiveness in Improving Safety


The research project will address how vehicles in a multimodal environment are managed and prioritized at curb loading and unloading zones between different public and private vehicles and/or use cases. The research will analyze the effectiveness of curb management practices in improving safety through reduced collisions with pedestrians and other vehicles. The research will look at current curb management practices across large and small urban areas in U.S., including use of technology, temporal management, street design and infrastructure, zoning for mode uses and prioritization, traffic monitoring, policies and regulations, permitting and monetization, and enforcement. The project will gather data and learn about safety outcomes as a result of the curb management practices in place and measure their effectiveness in reducing different kinds of collisions. Without further understanding of what constitutes effective curb management, safety outcomes at busy intersections and pedestrian activity centers may worsen the resulting number of collisions and degree of collision severity. This project explores what types of curb management practices can improve safety for all pedestrians and vehicles in multimodal environments.
