Trip and Parking Generation

Trip Generation

ITE has been a leader in trip generation data for more than four decades. ITE has recently released Trip Generation Manual, 10th Edition. This update offers not only modernized content but also contemporary delivery.

Users now have access to a significantly expanded and enhanced data set with more than 1,700 new data sites — a 30 percent increase — and new urban, person-based trip data. The ability to access the ITE trip generation data set has also been significantly improved through the introduction of searchable electronic material previously only available in hard-copy format and first-ever access to the underlying data through a new web-based application, ITETripGen.

Parking Generation - Pre-Order TODAY!

ITE has been a leader in parking generation data for more than three decades. The current edition of Parking Generation is the 4th Edition, published in 2010. Parking Generation Manual, 5th Edition will be released on January 31, 2019.

The updated manual will follow the lead of the modernized, updated, and expanded Trip Generation Manual, 10th Edition. The analyses in Parking Generation will differentiate the levels of parking demand observed at rural, general urban/suburban, dense multi-use urban, and center city core sites. Similar to Trip Generation, Parking Generation will be available in hard-copy, electronic, and cloud-based formats in order to cater to the format that works best for users.

A web-based app (ITEParkGen) will enable a user to produce parking generation data plots and statistics for the complete database as well as filtering by year and location.
