• the central processing unit 3 can be located in spatial proximity to the safety-critical traffic area 1, such as in the monitoring center of a tunnel, or also spatially far away, for example in a central traffic control center, which monitors several sections of the road. Based on the safety-relevant data of all dangerous goods or special transports 7.n, the central processing unit 3 determines a safety risk in the safety-critical traffic area 1 and uses traffic guidance signals to avoid an inadmissible safety risk, which are the accident risk of dangerous goods or special transports 7.n in the safety-critical traffic area 1 reduce.

The central processing unit 3 is thus informed that the dangerous goods or special transport 7.1 has left the safety-critical traffic area 1. Since there is no further dangerous goods or special transport 7.n in the safety-critical traffic area 1, the passage for the dangerous goods or special transport 7.2 is released (FIG. 4).
