VERKEHRSBEEINFLUSSUNG DURCH WECHSELVERKEHRSZEICHEN (TRAFFIC CONTROL BY MEANS OF VARIABLE MESSAGE SIGNS)

In urban areas it is generally not possible to increase the amount of space available to traffic, and there are limits to the way in which traffic can be controlled with light signals. At periods when the system is overloaded, with the attendant increased risk of accidents and increased air pollution, other traffic control measures must be taken to relieve or redistribute the traffic flow. For this purpose one can use variable traffic signs which are switched on only in the rush hours. Thus, detours can be avoided during off-peak periods. The theoretical considerations are clarified by means of examples. The system is applied to the town of Aachen in an attempt to see what extent the individual measures are sensible and can help to reduce the weak points shown by the analyses. Within the framework of a partial strategy in a section of the network data obtained in 'before and after' measurements are used to check the effects of the control measures. The most important results are that the degree of compliance could be calculated as 7.1% and the journey time saved on the alternative as compared with the standard route was 24%. It appears that also in urban networks and with relatively simple means recommendations can produce successful results.
