Title: HIGHWAY CAPACITY EXPANSION AND INDUCED TRAVEL: EVIDENCE AND IMPLICATIONS
Accession Number: 00748094
Record Type: Monograph
Availability: Find a library where document is available Abstract: At its 76th Annual Meeting in January 1997, the Transportation Research Board (TRB) presented a session on Highway Capacity Expansion and Induced Travel: Evidence and Implications. The session, which was sponsored by TRB's Committee on Transportation Planning Applications, included the presentation of four papers, comments by two discussants, and questions and comments from the audience. This report contains the four papers and a summary of the discussion following their presentation. The papers take a broad view of induced traffic. The papers also note the importance of geographic scope and time period in attempting to measure induced traffic by comparing traffic volumes before and after highway improvements. The papers distinguish induced traffic from growth in traffic that would have occurred with or without highway capacity expansion. Session participants identified several high priority areas for future research on induced traffic: (1) The development of simplified procedures to account for induced traffic in benefit-cost analyses of highway improvements; (2) More basic research on travel behavior oriented toward understanding the role of changes in travel times and costs on the amount of travel by households and businesses; (3) Retrospective studies, which compare observed volumes in highway corridors with forecasts; and (4) Before and after studies of major improvements in highway capacity. Review of the four papers and the discussion following their presentation suggests that the range of disagreement between highway proponents and opponents on the subject of induced travel has narrowed considerably.
