Part I of this report synthesizes the overall findings and conclusions of TCRP Project H-1 and the existing body of literature on transit and urban form. The literature was summarized at the conclusion of Phase I of this research project in TCRP Research Results No. 7. Empirical evidence from this project combines with previous research to demonstrate that transit and urban form relationships can be significant. Part II of this report provides guidance on the land use characteristics that support new fixed guideway transit services in a corridor. The work builds upon research conducted in the 1970's by Pushkarev and Zupan that established thresholds necessary to support transit in a cost-effective manner. That work is updated with data from current light rail and commuter rail cities and extended by considering the cost-efficiency (annual operating costs plus depreciation per vehicle mile) and effectiveness of service (daily passenger miles per line mile).
