Developed by Sisinnio Concas, Ph.D., and Phil Winters, TDM-CP, the Trip Reduction Impacts of Mobility Management Strategies (TRIMMS) model is a visual basic (VB) application spreadsheet model that estimates the impacts of a broad range of transportation demand initiatives and provides program cost-effectiveness assessment, such as net program benefit and benefit-to-cost ratio analysis.
The U.S. Environmental Protection Agency has paired the TRIMMS model with an evaluation framework (TEAM) to develop a comprehensive tool to evaluate the impact of travel efficiency strategy geared toward curbing emissions.
The TRIMMS model is a free downloadable sketch planning tool developed by the National Center for Transit Research and the Center for Urban Transportation Research.
