MONITORING TRAFFIC IN THE WHOLE MOTORWAY NETWORK: WHAT EFFECTS CAN BE EXPECTED?. SECOND INTERNATIONAL CONFERENCE ON ROAD TRAFFIC MONITORING

This article puts forward an argument for a comprehensive and co-ordinated traffic monitoring system in West Germany, and describes the functions and the design of such a system. Because it is neither necessary nor economically viable to have the same level of data collection on all road types, the roads within the road network are classified into four categories, according to the levels of traffic incidents detected upon them. The numbers of data detection points used for each road will vary according to road category. It is envisaged that about 2500 data collection points will be needed. Roadside equipment and data transmission methods would be standardized throughout the road network. Data will be preprocessed in local outstations, which will be scanned cyclically by the traffic control centres. A comprehensive update of the whole system will take place every 1-5 minutes. The graphical and textual display of data will be via a visual display unit. Data will be transmitted to drivers via the radio-data-system (RDS) on the traffic message channel (TMC). (TRRL)
