Freight-Demand Modeling to Support Public-Sector Decision Making NCFRP Report 8

摘要

Although the private sector is mostly responsible for developing and managing the nation's freight-flow system, public agencies often make investment and policy decisions that can affect the flows. To understand the shifts of traffic in the nation's freight flows, many state, regional, and federal agencies have begun to create freight demand models; however, these agencies need more capability to analyze freight demand. The authors explore possible ways to improve freight demand models and other analysis tools.
