Estimating Costs and Benefits of Emissions Reduction Strategies for Transit by Extending the TRIMMS Model

(Center Identification Number: 77932)

This study details the development of a series of improvements to the Trip Reduction Impacts of Mobility Management Strategies (TRIMMS™) model. TRIMMS now estimates a wider range of emission pollutants and incorporates a new module that evaluates the impact of land use strategies on transit patronage. TRIMMS uses the emission inventory of the Environmental Protection Agency Motor Vehicle Emission Simulator (MOVES2010a), which makes it suitable to run official State implementation air quality plan (SIP) and regional emissions analyses for transportation conformity purposes. This model enables the Florida Department of Transportation (FDOT), transit agencies, Metropolitan Planning Organizations (MPO) and local communities to conduct cost‐benefit assessments for most of the strategies identified in the FDOT‐sponsored Transit Ozone‐Reduction Strategies Toolbox, without the cost and expertise required by more sophisticated models.
