Consequences of the Development of the Interstate Highway System for Transit

TRB’s Transit Cooperative Research Program (TCRP) Research Results Digest 21: Consequences of the Development of the Interstate Highway System for Transit presents the literature review for TCRP Project H-13A, "Consequences of the Development of the Interstate Highway System." The aim of this project is to determine the effects of the interstate highway system on urban and suburban areas, focusing particularly on the effects for public transportation as an industry and as a service. The research phase of the project includes a comparative case study analysis of selected U.S., German, and Canadian cities analyzing the broad context in which interstate and similar highway projects were developed, their intended and unintended consequences, and their effects on public transportation systems and use.
