The Institute of Transportation Engineers (ITE) stands as a global hub for transportation professionals, and a cornerstone of their resources is the Trip Generation Manual. This comprehensive guide serves as an indispensable tool for estimating the traffic impact of new developments, a crucial step in urban and transportation planning. For professionals in transportation, zoning boards, and developers alike, understanding and utilizing trip generation data is paramount.
The ITE offers electronic access to this wealth of data through the ITETripGen web app, a user-friendly platform that encompasses a vast dataset. This dataset includes trip generation rates for diverse land uses across various settings, time periods, and variables. The latest iteration, the Trip Generation Manual, 11th Edition (TripGen11), and its accompanying web app, ITETripGen, represent the most current and enhanced resources available.

This edition is designed to be more user-centric, providing transportation professionals with the most accurate and relevant data for their projects.
Key Enhancements in the 11th Edition:
- Multimodal Data Integration: Recognizing the evolving landscape of transportation, TripGen11 incorporates the latest multimodal trip generation data. This includes insights for urban, suburban, and rural contexts, catering to a broader range of planning scenarios.
- Refined Land Use Classifications: The land use categories have been re-evaluated and refined to better align with user needs. This ensures that professionals can find more precise matches for their specific project types, leading to more accurate estimations.
- Digital Accessibility and Integration: The 11th Edition fully embraces digital integration. Users gain access to digital copies of land use definitions, data plots, and supporting materials. The ITETripGen web app allows for robust data filtering based on location, setting, data age, development size, and trip type.
- Advanced Data Analysis: The web app enables in-depth data analysis, filtering, and calculation functions specifically for the 11th Edition database. While focusing on the latest data, users can still access PDF versions of the 10th Edition and its supplement through the app’s Support Documents section.
Utilizing the ITETripGen Web App
The ITETripGen web app is the digital gateway to the Trip Generation Manual, 11th Edition’s extensive data. Purchasing the 11th Edition grants users a unique key code to create an account at www.itetripgen.org. This online platform is where users can:
- Access Comprehensive Data: Explore the full spectrum of trip generation data, plots, and reference documents.
- Customize Data Plots: Create tailored data plots to visualize trip generation rates relevant to specific project parameters.
- Filter and Analyze Data: Utilize powerful filtering tools to refine data searches based on various criteria, ensuring the data aligns with local conditions and project specifics.
Parking Generation Manual, 6th Edition: A Complementary Resource
Alongside the Trip Generation Manual, ITE also offers the Parking Generation Manual, 6th Edition. This manual is an educational resource focused on estimating parking demand for proposed developments. The companion web app, ITEParkGen, mirrors the functionality of ITETripGen, providing electronic access to parking generation data.
Key Updates in the Parking Generation Manual, 6th Edition:
- Enhanced Web App Interface: ITEParkGen features a streamlined user experience with single-click access to land use text and data plots in PDF format.
- Multiple Calculation Methods: Users can calculate parking demand using average rates, fitted curves, and the 85th percentile, offering flexibility in estimation approaches.
- Expanded Land Use Codes: The 6th Edition introduces new and reconfigured land use codes and subcategories, including Single Family Attached Housing, Multifamily Housing, Urgent Care Centers, Shopping Centers, and more, reflecting contemporary development trends.
Integrating Trip Generation into Traffic Impact Analysis
The data and methodologies provided by the ITE Trip Generation Manual are fundamental to conducting thorough traffic impact analysis studies. These studies are crucial for assessing the transportation implications of new developments and ensuring that infrastructure can accommodate anticipated traffic volumes.
Recognizing the importance of seamless integration, ITE has developed the TripGen11 API in collaboration with Transoft Solutions. This API enables third-party transportation engineering software, such as PTV Vistro, to directly access and utilize TripGen11 data. This integration streamlines workflows, allowing professionals to import ITE trip generation data directly into their analysis software and apply it within integrated transportation impact analysis processes.
Contributing to the Future of Trip Generation Data
The ITE Trip Generation Manual is a living document, continuously updated with voluntarily submitted data from public agencies, developers, and consulting firms. Transportation professionals are encouraged to contribute to this valuable resource by submitting their own trip generation and parking generation data. This collaborative approach ensures the manual remains relevant, accurate, and reflective of real-world conditions.
