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.
