An optimization model for improving highway safety
This paper developed a traffic safety management system (TSMS) for improving safety on county paved roads in Wyoming. TSMS is a strategic and systematic process to improve safety of roadway network. When funding is limited, it is important to identify the best combination of safety improvement proje...
