| Abstract: | In the case of traffic jam queuing,the method of calculating travel time based on theory of kinematic waves(TKW) is obtained and applied to the dynamic traffic assignment.On this basis,the time-discretized variational inequality model for dynamic user optimal problem is proposed,and a projection algorithm is designed to solve this model.An example was used to test the practicability of the model. |
