The objective of this project is to advance routing methods in hazardous materials (hazmat) transportation to mitigate the risk of hazmat accidents and provide fundamental building blocks to bring the current research and practice up to the next level. This project will provide essential theory and algorithms of Spectral Risk Measures (SRM) applied in hazmat transportation, which have the potential to radically change current research and practice in government planning for safer management of infrastructure. This project will deliver routing methods based on the SRM concept under data uncertainty and time dependency. SRM will be shown to be effective in low-probability, high-consequence applications. If successful, this project will provide the most advanced risk mitigation methods for hazmat routing.
