Trip Generation - Looking Back,
Moving Forward
Since 1976, ITE has been the go-to source for trip generation data
and tools. We have come a long way, particularly in the last five
years. The First Edition of Trip Generation was less than 200
pages and included only approximately 50 land uses. Today, we
provide a Web-based App allowing access to trip generation data
for 177 land uses, in rural, suburban and urban settings, parking
generation data, and are continuing to enhance the person-based
and multimodal aspects of our data set.
In February of this year, ITE released the Trip Generation, 10th Edition Supplement.
This supplement significantly expands the multimodal data available to users. It provides
walk, transit, and bicycle trip generation data for 53 land uses, adds truck trip generation
for 50 land uses, and includes a new affordable housing land use. It is available in both
digital and hardcopy in the ITE Bookstore; both include an upgrade to the ITE TripGen
Web App. A recorded webinar on the supplement is available on the ITE Learning Hub.
Thanks to our software partner, Transoft Solutions, for their continued support.
As we prepare to initiate the development of the Trip Generation Manual, 11th
Edition, planned for delivery in late 2021, we are enhancing our existing offerings and the
application of these resources. In 2019, we released the ITE Trip Generation Education
Program providing university professors and their students discounted access to ITE's
Trip and Parking Generation Manuals and lesson plans to guide their application in an
academic setting.
Later this summer, we expect to release a proposed recommended practice (RP) on
Multimodal Transportation Impact Assessments for Site Development to replace
the recommended practice published in 2010, led by Dan Hardyunder the auspices of
the Planning Council. The new RP will include assessing travel behaviors for multiple
modes in various land use types and contexts, tools for designing sites to encourage more
multimodal transportation use, using long-range plans to drive determinations in a site
assessments process and look beyond traditional Level of Service (LOS).
In the fall, we will debut a new Traffic Impact Analysis (TIA) Certificate Program
as part of our professional development program. This blended learning program will
allow those charged with preparing or reviewing TIAs to gain a full understanding of the
practice of traffic impact analysis. It will include the rationale behind conducting a TIA,
the steps involved in performing a TIA, training on the tools used in conducting analyses
for a TIA, and discussion of new and emerging issues. The ITE Public Agency and
Consultants Councils are supporting the development of this new program.
We have come a long way since releasing the first edition of Trip Generation in
1976, but we recognize the need to expand and evolve our offerings to keep pace with a
changing profession. Our volunteers and staff are working hard to keep ITE positioned at
the forefront of trip generation and traffic impact analysis, and we ask that you continue
to assist ITE in the on-going collection of both trip and parking generation data through
ITE's Trip and Parking Generation Web page. If you have thoughts or suggestions, feel
free to reach out to me at or on Twitter: @JeffPaniatiITE.
