Abstract:The Moving Ahead for Progress in the 21st Century Act includes a number of provisions advocating
improving the condition and performance of the national freight network through targeted investments and
policies by the Department of Transportation and state agencies. Critical to this network are freight
corridors which serve as major trade gateways connecting multiple cities and regions. However,
transportation planners and policy makers are limited by the number of tools available to assess the
performance and condition of these corridors. Most current tools and models require data which is either
unavailable, outdated or insufficient for analysis. To address this need, a truck-rail intermodal toolkit was
developed for multimodal corridor analysis and enables planners and other stakeholders examine freight
movement along corridors based on mode and route characteristics. The toolkit includes techniques to
acquire data for simulating line-haul movements, and models to evaluate multiple freight movement
scenarios along corridors. Example analyses examining truck and rail movements along 5 mode-competitive corridors are presented in addition to a case study of the Gulf Coast Megaregion. The
methodology described herein can be used in other multistate corridors and serve as an initial assessment
of the condition and performance of the national freight network.
