Abstract:
1. A method for controlling traffic flows having hazardous material or abnormal load transportation units through safety-critical traffic zones, comprising: reading out safety-relevant data from a signal transmitter disposed on a hazardous material or abnormal load transportation units when it passes by a read devices disposed at an entry zone of the safety-critical traffic zone; transmitting the safety-relevant data from the transportation unit at the entry zone to a central computation unit; determining a safety risk in the safety-critical traffic zone by the central computation unit, the central computation unit comparing the safety-relevant data from the transportation unit at the entry zone with the safety-relevant data of all the hazardous material or abnormal load transportation units currently present in the safety-critical traffic zone; and regulating the flow of traffic by setting traffic control signals by the central computation unit to avoid an impermissible safety risk, the traffic control signals reducing the accident risk for a hazardous material or abnormal load transportation unit in the safety-critical traffic zone.
