摘要

Active traffic management consists of a series of integrated congestion management strategies including speed harmonization, queue warning, hard shoulder running, dynamic rerouting, travel time signs, ramp meter control, managed lanes, etc. This study aims to provide a comprehensive review and comparative analysis on various active traffic management strategies and their application. The detailed analyses of the key technologies are provided, and the system benefit, safety, and equity concerns are addressed in this paper. The findings of this study indicate active traffic management systems demonstrate the great potential for freeway congestion mitigation and safety enhancement.
