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
