Evaluation of Freight Vehicles in Short-Haul Intermodel Lanes

| 摘要： | The further development of intermodal truck-rail freight services is a leading strategy in the mitigation of growing highway congestion. Unfortunately, the effectiveness of this policy alternative is limited by the dominance of "short-haul" truck movements that cannot be economically diverted to intermodal service under current business models and practices. A chief impediment to the development of short-haul intermodal services lies in the characteristics of freight vehicles - primarily truck trailers and containers. Current practices rely on lift-on / lift-off technologies that depend on high-volume mechanized terminal facilities. The high fixed costs of these facilities must be averaged over relatively long shipment distances for intermodal freight to compete with traditional trucking. Therefore, most short-haul movements are not currently candidates for intermodal carriage. In response to this need, the University of Tennessee's Center for Transportation Research (CTR) is performing a comprehensive evaluation of rail-truck intermodal equipment that examines current capabilities and costs and identifies vehicle characteristics required to extend intermodal services to shorter-haul markets. This analysis includes (1) the development of a thorough and robust costing model that allows simultaneous variations in intermodal vehicles, accompanying equipment suites (cranes, drayage vehicles, etc.), intermodal operating practices, and lane specific traffic volumes; (2) a careful description of the characteristics and usage patterns of currently available intermodal vehicles; (3) an evaluation of emerging intermodal equipment alternatives; and (4) an evaluation of the economic conditions that would be necessary for any foreseeable intermodal technology to compete effectively in freight markets that are currently dominated by all-truck movements. |
