摘　　要：根据交通波理论导出在路段产生拥挤排队时的交通阻抗,并把该阻抗应用到动态交通流分配中,在此基础上建立离散化条件下动态用户最优配流问题的变分不等式模型,并用投影算法求解此模型,给出算例验证模型的实用性.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 algo- rithm is designed to solve this model. An example was used to test the practicability of the model.
