摘要：	The Transportation Research Board's (TRB's) Committee for the Study of Freight Capacity for the Next Century was convened to examine indications that the freight transportation sector, which has in recent decades facilitated productivity growth, instead threatens to become a hindrance to the economy. Participants in the industry have noted that in some segments investment in capacity is not growing at the same rate as traffic, shifts in freight patterns are creating bottlenecks that degrade performance, and adding capacity is becoming more expensive and difficult. The committee undertook two tasks: first, to examine the trends in the sector that have been the sources of concern in order to assess the risk that efficiency gains might not continue; and second, to propose changes in government policy that will increase capacity by enhancing the efficiency of freight transportation and promoting more rational investment.
