Evaluating Operational Resilience of Highway Corridor, using GIS-based Freight Network
Track: Transportation
Authors: KAUSHIK BEKKEM

Various transportation systems face unplanned emergencies, disruptions and disasters. Such disruptions, like the severe winter storm in February 2008 along I90/94 corridor in Wisconsin, affect the overall economy by constraining the flow of commodities, and have a significant impact on travelers. This research provides operational resilience information and identifies top high-risk segments that will help ensure reliable function of an Interstate Highway Corridor in Wisconsin
The research uses GIS to model the freight flows obtained from the commodity flow database Transearch®. The GIS network framework built uses ArcGIS Network Analyst® and spatial analysis capabilities for finding alternative routes to disruptions, assessing operational resilience by considering the operational and service level impacts on travel distances and travel times. The assessed vulnerabilities of infrastructure elements along with evaluation metrics and alternate route analysis are used to determine an overall resiliency rating for each corridor segment, thus resulting in prioritization of corridor segments.
