Transportation Impact Review

The City’s transportation impact review process is developed to guide traffic consultants and developers throughout project development and to ensure potential impact on traffic, parking, transit usage and pedestrian amenities.

The City’s Transportation Impact Analysis Guidelines

The City’s transportation impact analysis guidelines (TIA) is developed to guide the developers throughout project development process, and assess the project’s potential impacts on pedestrian, bicyclists, transit, and motorists. Mitigation measures and/or project approval conditions are developed in accordance to the policies of the General Plan Mobility Element.

The City’s overall approach to analyzing project impacts and cumulative impacts is consistent with the California Environmental Quality Act (CEQA).

The City of Pasadena model is consistent in form and function with standard travel forecasting models used in transportation planning. The model includes a land use/trip generation module, a gravity-based trip distribution model, and a capacity-restrained equilibrium traffic assignment process. The travel model utilizes Version 5.0 (Build 1515) of the TransCAD Transportation GIS software, which is consistent with many of the models used by local jurisdictions in California and throughout the nation. The Southern California Association of Governments (SCAG), the metropolitan planning organization (MPO) for Southern California, maintains their current regional travel demand model in TransCAD.
