FLOW IMPROVEMENT BY PROVIDING PARTIAL TRAFFIC INFORMATION FOR ROAD USERS

摘要

In this paper, we investigate two two-route tra±c models, i.e. asymmetric and symmetric tworoutentra±c models, with mean velocity information feedback strategy. The simulation resultsnshow that, for asymmetric two-route model, average °ux can be signi¯cantly improved if onlynpartial road information is provided for road users. However, for symmetric two-route model,naverage °ux of the two routes adopting information feedback cannot outweigh the °ux of twonroutes chosen completely at random. We explain the results by studying the vehicle number onntwo routes. We hope the study may provide a good suggestion to the design of AdvancednTraveler Information Systems.
