Quantifying Net Social Benefits of Vehicle Trip Reduction Impacts to Make Existing Road Infrastructure Perform Better - Guidance for Customizing the TRIMMS Model to Aid Local, Regional and State Decision Makers

TRIMMS permits program managers and funding agencies like the Florida Department of Transportation (FDOT) to make informed decisions on where to spend finite transportation dollars based on a full range of benefits and costs. The model allows some regions to use local data or opt to use defaults from national research findings, select the benefits and costs of interest, and calculate the costs and benefits of a given program. A key strength of this model is its wide range of benefits and costs that can be selected for the analysis. The model's flexibility and robustness allows it to be adopted by agencies throughout the country. The objective of this study is twofold. First, a collection effort will be conducted to obtain cost and benefit parameters to allow model customization at a regional level. In addition to this data collection effort, the model will be updated and refined to allow the incorporation of regional parameters. Finally, this project will provide the research and documentation necessary to help professionals to use the model by selecting the appropriate cost parameters, providing a reference to sources where o such parameters can be obtained, and by offering general guidance on how to incorporate data already at their disposal.
