中文摘要：
利用基于路段的元胞传输模型进行模拟，给出了一种计算实际路段出行阻抗的方法，并在此基础上构造了基于路段变量的动态用户最优变分不等式模型．模型采用针对迄节点的路段变量，在每一个小时段都能给出路段流入率、流出率、路段流量和实际路段阻抗，为用户提供较为全面的诱导信息打下了较好的理论基础．采用，修正投影算法来进行求解．数值算例表明模型具有的实用性和优越性，使道路交通流宏观模型与动态网络交通配流问题得到较好的结合．
英文摘要：
This paper develops a method for estimating the link travel time by using the cell transmission model （CTM） and formulates a variational inequality problem of dynamic user optimal （DUO） based on the link variables. In our DUO formulation, the variables are towards the destinations, which, at each interval, can provide the link inflow rates, the link outflow rates, the link flows and actual travel times, consequently providing complete inducing information for travelers. To get the solutions, we employ a modified projection method for the problem based on link variables. Our DUO formulation is a good combination of the road traffic flow model and the network traffic assignment problem. Its practicability and advantages are confirmed by numerical simulation.
