Studying the Impact of a Distance Constraint and Inspection Points on Hazmat Transportation Risk

There has been much recent interest in controlling risk of hazmat transport via road bans and curfews and the use of tolls. The purpose of this thesis is to explore a new method of controlling hazmat transport risk by placement of inspection points. Our method strategically places inspection stations while requiring that each hazmat truck visit an inspection station after driving a given specific distance. A tradeoff is sought between total driving distance and risk. An exact solution is presented to the problem, followed by the development of a greedy heuristic solution that attempts to reduce the number of inspection stations and risk. This solution procedure is then applied to a real-world case study problem of Revenna (Italy). Computational results are discussed with a comparison of risk with the distance constraint and number of inspection stations.
