Automatic incident detection in Hindhead Tunnel, UK
This paper presents details of a tunnel radar incident detection system that has been deployed by the UK Highways Agency, in Hindhead Tunnel on the A3, a dual carriageway truck road that runs from London to Portsmouth. The process that was followed when choosing a radar based system is described, along with the main end user requirements. Finally, examples of real incident events are shown, detected by ClearWay during normal operation of the highway.
