What is the ITE Trip Generation Manual?
The ITE Trip Generation Manual is a nationally recognized source for determining the anticipated number of trips for a diverse set of land uses and associated sizes/densities.
It is a summary of trip generation data compiled from studies throughout the United States and Canada that were voluntarily collected and submitted.
Each iteration of the manual seeks to expand its database, reclassify land uses, and modernize its approach to estimating vehicle and multimodal trips to reflect our ever-changing world.
