摘要：	The National Commission on Intermodal Transportation indicated that "the national intermodal transportation system should ensure funding of projects of national or regional significance" (National Commission on Intermodal Transportation 1994). Defining "projects of national significance" in a way useful to funding agencies and planners is not easy. Experience under the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) indicates that even the long-standing process of designating and prioritizing traditional passenger projects is awkward at best and that meritorious freight projects can come in many shapes and sizes. In this paper several candidate projects are examined to illustrate the range that may be encountered and the issues involved in attempting to define and locate others. The primary objective of a working definition is not theoretical or political correctness but usefulness in helping to find and support the most cost-effective freight transportation projects. Practicality is crucial. A successful working definition must also be broadly applicable, must aid planners in locating candidates, and must facilitate prioritization. We need a robust definition that can serve us well in unfamiliar and ambiguous territory. This paper discusses several of the issues faced in locating such projects and measuring their significance. Key barriers and needs are identified. Two basic approaches are described and compared. Finally, conclusions concerning the existence of other freight projects of national significance and the outlook for locating, describing, and justifying them are offered.
