Revisiting TODs: How Subsequent Development Affects the Travel Behavior of Residents in Existing Transit-Oriented Developments
Nathan McNeil
Jennifer Dill
Does living in a transit-oriented development (TOD) actually change the way people travel? That's the fundamental question that 15 years of research in Portland, Oregon seeks to answer.
Since 2005, Portland State University has worked with Portland’s Metro regional government to survey occupants of buildings for which developers had received funding from Metro’s Transit-Oriented Development (TOD) Program. Metro strategically invests in TODs to help more people live, work and shop in neighb...

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department ...
