Identifying and Using Low-Cost and Quickly Implementable Ways to Address Freight-System Mobility Constraints. NCFRP Report 7

摘要

Increasing freight demand and capacity constraints present several challenges to the management and operation of the freight transportation system. Recent studies and statistics document the inadequate capacity and the resulting increasingly costly congestion--not only on the nation's highways but also in metropolitan areas, at water ports, railroads, airports, and intermodal facilities. The ability to increase freight transportation capacity to meet demand is constrained by geographic barriers, population density, and urban land use development patterns. The consequences of this increased freight demand and increased density include increased congestion, travel delay, emissions, and commercial operational costs, among others.
