Title: Too Many Trips? Problems with Trip Generation in Theory and Practice
Accession Number: 01475790
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: Trip Generation is the standard reference for assessing the impacts of new development on traffic congestion and the environment in the U.S. However, a comparison to household surveys suggests that Trip Generation overestimates trips by 56% – likely because its data represent a biased sample of development in the U.S. Moreover, the data in Trip Generation are ill-suited to analysis of regional traffic impacts, imposition of development impact fees and studies of greenhouse gas emissions, because they do not account for substitution effects. Most trips to new developments are not new, but involve households reshuffling trips from other destinations. These twin problems – theoretical and practical – help reinforce the dominance of the private auto, and are likely to lead to excessive roadway infrastructure that is unnecessary in practice.
