Job-Worker Balance & Polycentric Transit-Oriented Development: Toward Indices and Spatio-temporal Trends

Robert Hibberd
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

Metropolitan Centers: Evaluating local implementation of regional plans and policies

Richard Margerum Keith Bartholomew , Rebecca Lewis
One of the emerging strategies in metropolitan regions for integrating transportation and land use is to promote development around higher density mixed use centers (metropolitan centers). Considerable research has focused on the design and performance of centers, particularly those linked to fixed transit (transit oriented development). These studies have focused on urban design, the impacts of centers on behavior and the changes induced by fixed transit investment. However, there has been far… Read More
