The objective of this paper is to develop an analytical model to identify key Interstate segments at which trucks are frequently diverted because of a disruption in service and to determine an appropriate alternate route under such circumstances. Through the use of a risk-based approach, segments of the Tennessee Interstate system were selected according to histories of serious incidents, incidents with diversions, and high truck volumes. In the selection of a preferred diversion route, the shortest alternate path may not be feasible for truck use because of varying size and performance characteristics. To address this consideration, a geographic information system (GIS) was used; in the GIS, restrictions and costs were applied to candidate diversion routes to either eliminate or penalize routes undergoing evaluation. The alternate route assessment methodology illustrates the need for improvements in nationwide truck freight networks as well as the ability for GIS tools to address complex routing problems. Most alternate routes studied as part of this project were affected by these restrictions. Use of this methodology can lead to reduced congestion and increased reliability in travel time for trucks and other vehicular traffic.
