Controlling traffic tunnels is a complex task which imposes serious requirements. Tunnel safety depends largely on alerting motorists and tunnel personnel of a traffic incident in a timely manner. Such an alert must be based on a reliable and complete monitoring of tunnel activities. Highway tunnels are already equipped with basic video systems mainly for supervising by tunnel stuff and guidance of emergency activities. Effective incident management completely depends on fast incident detection and fast incident verification. Due to the huge amount of information provided by video systems, image analysis might help human operators to detect unexpected events and prevent dangerous situations. This paper summarizes our present study called VITUS-1. The feasibility study VITUS-1 defines a concept mainly based on digital video image analysis in order to accomplish the following tasks: (1) automatically recognizing alarm situations in road tunnels; (2) alerting the tunnel personnel and � if necessary � the road users; and (3) automatic storage of traffic incident video sequences.
