In order to enhance the level of traffic information perception in highway tunnels and meet the needs of digital and intelligent development of highway tunnels,a traffic control system based on radar-video fusion perception technology has been established.This system realizes radar-video fusion perception by a process of spatiotemporal matching,ROI(Region of Interest)target fusion,and distance fusion.The system architecture comprises five layers:equipment,communication,data,application,and user.Driven by key technologies such as radar-video fusion and digital twin,four major application platforms have been established:3D real-world control,data analysis and judgement,emergency linkage control,and information sharing.These platforms enable functions such as holographic perception,multi-source fusion,event research and judgement,auxiliary decision-making,intelligent control,and fine management.An exemplar case of the Jilai Expressway tunnel group illustrates that the highway tunnel traffic control system,based on radar-video fusion,can precisely perceive tunnel operating conditions.Consequently,this system provides substantial technical support for information perception and intelligent management and control of highway tunnels.
