Next Evolution in Transportation Impact Analysis

Now Available! The TripGen11 API, developed by Transoft Solutions for ITE, allows for third-party transportation engineering software providers to link their products directly to the ITE TripGen 11 app and gives users to extract data needed for analysis. 

ITE has initially partnered with PTV Group to offer integration through their software platform, PTV Vistro. The ITE TripGen11 API allows users to import ITE Trip Generation data for proposed project land uses directly within the software and apply the results in integrated transportation impact analysis workflows.

Through PTV’s Vistro software, users can select the land use characteristics, independent variable and time period. Then, choose to apply the average rate or fitted curve equation and view the results in Vistro’s trip generation table and on the ITE formatted data plot graphics.

Information about purchase the Trip Generation Manual, 11th Edition to gain access to TripGen11 App is below. To learn more about PTV’s Vistro, click here. If you are interested in partnering with ITE on API integration, contact Kevin Hooper.
