Developing Detailed Freight Routing Model for U.S. Transportation Network

Review of a high-level regional routing model for estimating annual origin-to-destination freight movements, assigning them to the U.S. transportation network, and analyzing impacts of demand and supply changes. The presentation includes macroeconomic and mesoeconomic modeling components and specific investment feedback levels. Key topics covered: Database Development, Multimodal Freight Routing Model, and Scenario Analysis.

  2. High-level Regional Routing Model Objectives: Develop a model to: Estimate the annual, geographically detailed origin-to-destination movements of freight of interest to the Corps, by mode and by commodity Assign these movements to the U.S multimodal transportation network and Estimate the effects of changes in demand and network-based supply on these flows and their costs
