Abstract
A freight route resiliency indicator is developed in this paper. Basic characteristics of connected vehicle technology (CVT) which can provide advance traffic information is used to develop the indicator. The indicator is sensitive to route changes that might occur due to detour from an unforeseen congestion downstream of the path of the freight truck. The truck can detour at an appropriate exit on its route. This could be done to maximize the route resiliency. Application of the indicator is shown with a 20-mile stretch of I-710 (interstate 710) freeway of the multimodal freight transportation network in the Southern California Region. I-710 is considered as one of the most important truck routes connecting Ports of Long Beach and Los Angeles to other multimodal terminals of California and elsewhere in the United States. It is found that the truck route resilience is maximized if the truck detour occurs at approximately 7th, 6th and 4th exit-ramps downstream from the truck location with probability 0.75, 0.5 and 0.25, respectively. This indicates trucks ability to avoid the downstream congested point with these three probabilities. The resilience indicator developed in this research is extremely useful for resiliency improvements of freight operations in urban regions where congestion occurrence is quite frequent and random. © 2020 The Authors.
