INDUCED HIGHWAY TRAVEL: TRANSPORTATION POLICY IMPLICATIONS FOR CONGESTED METROPOLITAN AREAS

Patrick DeCorla‐Souza

Open publisher page 18 citations

Abstract

Certain perceptions about the impacts of induced highway travel prevail among some metropolitan transportation stakeholders and are as follows: 1) new personal highway travel induced by highway expansion accounts for most of the observed travel growth; 2) metropolitan planners do not account for induced personal highway travel in their traffic forecasts for expanded highways; and 3) it is pointless to expand highways because induced personal highway travel consumes most or all of the added capacity. These negative perceptions are being used as arguments to stop highway expansions in metropolitan areas. This paper acknowledges that induced travel is an issue that needs to be addressed, clarifies the issues, and discusses how the issues can be addressed in the transportation planning process and in transportation investment decisions.
