Everyday in our cities the shipments of hazardous materials such as explosives, gases, flammable liquids, toxic substances, and radioactivematerials are demanded.

Abstract

Everyday in our cities the shipments of hazardous materials such as explosives, gases, flammable liquids, toxic substances, and radioactivematerials are demanded. These shipments are indispensable to our modern way of life (to fuel vehicles, to heat buildings, to carry out hospital therapies, etc.), although they can be harmful to the people and the environment in case of an accident. While there are many possible interventions for risk mitigation, here we focus on the policies of government agencies to regulate the itineraries of the hazmat shipments. Two main research lines can be identified in the literature: i) enforce specific itineraries to vehicles; ii) prescribe a set of rules that vehicles itineraries have to respect. In the present work we propose an alternative policy tool for indirectly regulating the hazmat transport. It consists of imposing check points along the routes, so called gateways, and stating the rule that each carrier, on its route from origin to destination, must pass through a specific gateway. Each carrier will select the minimum cost detour by the assigned check point. In turn, the administrator will select the location of a given number of check points on the network, and which check point has to be assigned to which carrier, so that carrier responses will minimize total risk. We call such problem the Gateway Location Problem for multicommodity flow (GLP).
