Smart Growth Trip Generation

Study Findings

Caltrans initiated the Smart Growth Trip Generation project to determine the difference in vehicular trip generation between the suburban-oriented Institute of Transportation Engineers rates and those determined from surveys of California smart growth developments.

TTI was contracted to produce a validated and improved estimation method and a user-friendly tool to more accurately estimate trip generation for use in determining proper transportation improvements for smart growth developments in California and beyond. To improve the accuracy of the trip generation estimation model previously developed, this project collected trip generation data at approximately 30 smart growth sites and combined it with data already in the California Department of Transportation (Caltrans) database.
