scope:

The Trip Generation Handbook, 2nd Edition is a recommended practice of ITE and has two primary purposes: to provide instruction and guidance in the proper use of data presented in the Trip Generation Manual, 9th Edition and to provide information on supplemental issues of importance in estimating trip generation for development sites.

Because the instruction and guidance in the main body of this handbook represents a recommended practice for estimating trip generation, its function is distinct from the informational portions of the Trip Generation Manual, 9th Edition.

The analysis methods presented in the Handbook have been developed to be simple and understood by the novice transportation planner/engineer, yet sufficiently accurate for the experienced transportation professional.

Prior to publishing the Trip Generation Manual, 9th Edition, ITE separated the processing and dissemination of the informational trip generation data from the development of recommendations on how to use and apply the data. To facilitate the use of these documents, the Trip Generation Manual, 9th Edition combines the informational report (User's Guide and volumes 2 and 3, data) with the recommended practice material contained in the Trip Generation Handbook, 2nd Edition.

It should be noted that the Trip Generation Handbook, 2nd Edition is published in its current form and has not been updated to reflect changes in the Trip Generation Manual, 9th Edition.

Work is underway to revise this recommended practice with an expected release date at the end of 2013 or beginning of 2014. The revised recommended practice will be released as an e-publication.
