ITE Trip Generation - What's New in 12th Edition

When: September 29, 2025 | 2:00 -- 3:00 PM ET

Webinar Description:

This webinar will introduce participants to the newly released Trip Generation Manual (TGM), 12th Edition. This updated edition incorporates data from more than 550 new sites, introduces nine new land use classifications, and refines the database by removing pre-1990 data to ensure greater relevance. It also expands the Desk Reference with new and enhanced chapters on trip generation basics, emerging trends, and approaches for applying the Trip Generation Handbook. Attendees will learn how these updates improve accuracy and usability, explore emerging trends in trip generation, and gain insight into what is next for the future of trip generation resources.
