Abstract

Disclosed are a method and a traffic routing system for controlling traffic flows in which hazardous or special material is transported through safety-critical traffic zones such as tunnels, bridges or locks. In the method and traffic routing system, safety-relevant data is read with the help of a signal transmitter disposed on the transported hazardous or special material and is transmitted to a central computer unit when said vehicle passes reading devices located in the safety-critical traffic zone. The central computer unit determines a safety risk in the safety-critical traffic zone on the basis of the safety-relevant data of all transported hazardous or special material located in the safety-critical traffic zone and sets traffic routing signals.
