The main goals of this research project are to implement a Variable Speed Limit (VSL) system to improve safety and reduce closure frequency and durations on the Elk Mountain corridor. A draft decision support system has been created to effectively and consistently implement the Elk Mountain VSL system. The decision support system was created to reduce the speed variability in the corridor during adverse weather conditions, which should result in fewer crashes and shorter road closures over the long term. The Elk Mountain corridor is located in southeastern Wyoming on Interstate 80 between Laramie and Rawlins. The corridor carries approximately 11,000 vehicles per day. On average, approximately half or more of those vehicles are trucks carrying freight. |
