%X The recent hazardous material (hazmat) shipment ban in Washington, D.C., has led to debates, legal challenges, and considerations by other major cities to pursue similar actions. This article presents a methodology for evaluating hazmat shipment routing options on railroad networks under situations such as the shipment ban. A case study involving three alternatives is presented. Population and other vulnerable people within a 0.8 km (or 0.5 mile) radius buffer zone along the rail line are used to evaluate the potential risk associated with ultra-hazardous material (i.e., explosives, flammable gasses, poisonous gasses, and poisonous materials) shipments. Based on this study, it is concluded that moderate increases in ton-km, and subsequently time in transit, will be a result from the rerouting. On the other hand, the overall population at risk will see a reduction. The population-at-risk burden, however, is simply shifted from one location to other locations. This article also identifies areas for potential follow-up efforts.  Keywords: hazardous materials (hazmat); railroad; transportation security; freight movement; terrorism; routing; transportation cost<p />
