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.

Project UCARE: Uniform Commuter Assistance Reporting and Evaluation for TDM Programs

Moving Ahead for Progress in the 21st Century Act (MAP-21) places emphasis upon results and better management of programs for effective and efficient service delivery. With an increased focus on measuring performance, the transportation demand management (TDM) industry lags other areas of transportation. Without consistent methods of evaluating performance and calculating those benefits, the TDM community is at a distinct disadvantage when transportation investments are being considered at the local, state, and federal levels. This project sought to develop an accurate and sustainable online system to record data and use a consistent and defensible method for calculating the impacts of TDM programs. A literature review and a survey of TDM professionals were used to identify the key outputs and outcomes used today by commuter assistance programs. The data collection tool was pilot tested. The data from the survey … Read entire article »

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

(Center Identification Number: 77932) The objective of this research is to extend the evaluation of transit emission reduction strategies to provide a methodology for assessing the full benefits and costs associated with the implementation of the ozone reduction strategies and to account for a broad spectrum of emission pollutants. … Read entire article »

Developing a Technique that Predicts the Impacts of Transportation Demand Management (TDM) on a Transportation System

(Center Identification Number: 77809) Given declining resources, pressing problems, and environmental constraints, state departments of transportation (DOTs) are increasingly motivated to manage peak demand of vehicle trips as a way to mitigate congestion and improve overall performance of the highway system. … Read entire article »
