ITE has initiated an update to the Trip Generation Handbook, a companion resource to the Trip Generation Manual that provides practical guidance on the application and interpretation of trip generation data. The update is being led by a team of subject matter experts representing a broad range of practice areas and will ensure the Handbook continues to reflect current methodologies, industry practice, and emerging transportation trends.
About the Handbook Update
The Trip Generation Handbook serves as a practical resource for transportation professionals by providing guidance on the appropriate application and interpretation of trip generation data. As the profession continues to evolve, this update will modernize the Handbook to better support practitioners in planning, development review, and transportation impact analysis.
The update is expected to include:
Work is currently underway through a series of subgroups, each responsible for reviewing and updating assigned sections of the Handbook. The project is anticipated to conclude in 2027 following technical review and final publication.
ITE will provide periodic updates as the project progresses and may seek broader community feedback during the review process.
