| Abstract: | In the traffic system,because of the incomplete information,each of the road users will measure the real traffic with random deviation inevitably,and select path with random.So it＇s more appropriate to use logit dynamic to describe the evolution of traffic flow.In this article we established a joint optimization model of road tolls and capacities using the optimal control theory based on logit dynamic,which can optimize transportation system by controlling the level of time-varying road pricing and capacity.Through a simple example,we give analysis and prediction to traffic flow based on logit dynamic,and provide theoretic support for guidance strategy. |

| Keywords: | congested road-use pricing Logit dynamic optimal control theory road capacity |
