Abstract

In this paper, we investigate toll setting as a policy tool to regulate the use of roads for dangerous goods shipments. We propose a mathematical formulation as well as a solution method for the hazardous materials toll problem. Based on a comparative analysis of proposed mathematical models, we show that toll policies can be more effective than the popular network design policies that identify road segments to be closed for vehicles carrying hazardous materials. We present a summary of computational experiments on a problem instance from Western Ontario, Canada.
