According to new research, transit-oriented development (TOD) can address the equity challenge of "spatial mismatch," where urban residents are isolated from relevant employment centers, and significantly improve employment access. "Job-Worker Balance & Polycentric Transit-Oriented Development: Toward Indices and Spatio-temporal Trends," funded by the National Institute for Transportation and Communities (NITC), examines how transit-oriented development (TOD) affects employment access and… Read More

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