摘 要：This report provides a review of scholarly literature with direct relevance to the topic of modal shift and high-speed rail (HSR). HSR systems are usually planned on the expectation that they will attract riders who would have chosen other modes (such as air, automobile, bus, etc.) had the HSR not been created. Identifying and measuring the actual ability of HSR to effect modal shift is therefore critical. This report examines the evidence concerning HSR and modal shift in both secondary analyses of previous studies and in newer studies that use primarily original data. The studies that were reviewed comprise a large variety of HSR systems, time periods, data sources, and means of analysis.
