    Trip Reduction Impacts of Mobility Management Strategies (TRIMMS)

    10am, October 02nd, 2015

    Trip Reduction Impacts of Mobility Management Strategies (TRIMMS) is a visual basic 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.

    TRIMMS evaluates strategies directly affecting the cost of travel, like public transportation subsidies, parking pricing, pay-as-you-go pricing, and other financial incentives. TRIMMS also evaluates the impact of strategies affecting access and travel times and a host of employer-based program support strategies, such as: alternative work schedules, telework and flexible work hours, and worksite amenities.

    Key questions addressed:

    • What is the impact of transportation demand initiatives?

    Sample data inputs:

    • Program costs
    • Duration
    • Total employees or commuters affected

    Sample quantitative outputs:

    • Changes in mode share, trips, and vehicle miles of travel
    • Changes in all relevant cost externalities (i.e., air pollution, congestion, fuel consumption, climate change, health and safety, noise pollution)
