考虑一个被路径诱导系统支持的交通网络,装有ATIS的出行者接受交通中心的指挥、按照系统最优的原则选择路径,没有该装置的出行者根据个人成本最小的原则择路,建立了刻画这种混合交通行为的变分不等式模型,推导了混合交通行为网络的效率损失上界,并以多项式路段成本函数为例给出了一些上界的特殊值.研究表明,效率损失上界与具体被研究的网络结构和交通需求水平有关,只有在特殊情况下,才可以得到与网络需求和网络结构无关的上界值.
Consider a transportation network supported by a route guidance system. Travelers with ATIS receive the command of a traffic center and choose the route according to the optimal system principle. Travelers without this route choose the route according to the principle of minimizing personal cost, and establish a portrayal This variational inequality model of mixed traffic behavior deduces the upper bound of efficiency loss of hybrid traffic behavior network and gives some special values of the upper bound with the polynomial cost function as an example.The results show that the upper bound of efficiency loss and the specific The structure of the network under study is related to the level of traffic demand. Only under exceptional circumstances can we get the upper bound that is independent of network requirements and network structure.
