该文通过构造特殊形式的有效集来逼近KKT点处的有效集,给出了一个任意初始点下的序列线性方程组新算法,并证明了该算法在没有严格互补松驰条件的情况下具有全局收敛性和一步超线性收敛性。

This paper studies how to generate the reasonable information of travelers' decision in real network. This problem is very complex because the travelers' decision is constrained by different human behavior. The network conditions can be predicted by using the advanced dynamic OD(Origin-Destination, OD) estimation techniques. Based on the improved mesoscopic traffic model, the predictable dynamic traffic guidance information can be obtained accurately.A consistency algorithm is designed to investigate the travelers' decision by simulating the dynamic response to guidance information. The simulation results show that the proposed method can provide the best guidance information. Further,a case study is conducted to verify the theoretical results and to draw managerial insights into the potential of dynamic guidance strategy in improving traffic performance. 相似文献

基于Greenshields模型,描述了瓶颈路段上流量的演化过程,并计算每个时刻出行者的出行费用。通过出行费用与流量的关系调整每个时刻流量的分配,直至达到用户平衡状态。文中在拥挤时段设置了一定水平的收费,并分析了收费后路段上的流量分配情况和拥挤状况。在现象分析后得到了较好的收费水平和收费时段,以及收费对缓解交通拥挤的作用。 相似文献
