An optimal variable speed limits system to ameliorate traffic safety risk
A proactive traffic safety improvement variable speed limits control algorithm is proposed. A real-time crash risk evaluation model is adopted along with the extension of METANET traffic flow model. The control algorithm was tested for a mountainous freeway bottleneck area through VISSIM. Improved traffic safety has been concluded under high and moderate driver compliance levels.
