PERFORMANCE OF DRGS IN DIFFERENT SIZE NETWORKS

The Dynamic Route Guidance System (DRGS) concept is one method available to improve the efficiency of the road traffic network. The need for developing a DRGS evaluation model has been identified and the structure of theframework has been reported earlier. The evaluation model adopts simulation techniques using an event update microscopic simulation method. The model accounts for guided and unguided motorists as two distinct types of road users and their route selection process has been modelled to reflect the behaviour with or without dynamic route guidance information. Unguidedmotorists have been further classified as passive and active motorists toallow for modification behaviour of some unguided motorists. In the research presented here, an attempt has been made to investigate the application of the DRGS concept on different size networks. The model has been applied to study three networks referred to as small, medium and large. Eachnetwork has been investigated under varying proportions of guided motorists. The preliminary investigations suggest that the DRGS concept could bemore effective in relatively large networks. The findings also suggest that DRGS can be an effective measure to reduce the network-wide congestion. (a) For the covering entry of this conference, see IRRD abstract no 861490.
