| 摘 要： | 研究了收费情形下多用户类随机交通分配网络中,随机用户均衡相对系统最优的效率损失问题,运用变分不等式方法得到它的上界。研究发现,无论采用时间度量准则还是费用度量准则,相对于系统最优的效率损失上界都与路段出行时间函数类、出行者的社会经济特性、道路收费、网络复杂程度、网络总出行需求以及出行者对网络的熟悉程度相关。

| Abstract: | The efficiency losses of multiclass stochastic user equilibrium traffic assignment under road pricing against system optimization(SO) was investigated.The upper bounds of efficiency losses were analytically derived by variational inequality method.It is shown that whether using the time-based or monetary-based measures for decision making,the upper bound against SO always depends on the class of link travel time functions,the users' socio-economic characteristics,the road pricing scheme,the network complexi... |
