摘要
利用变分不等式方法研究了非可加路径费用的交通网络平衡问题,给出了与平衡条件等价的变分不等式模型,它包含了可加路径费用的网络平衡模型。此外,讨论了模型解的存在性和惟一性条件,这为进一步研究一般交通网络的用户平衡问题提供了条件。
A variational inequality approach is utilized to study traffic network equilibrium problem with non-additive path cost. An equivalent variational inequality model is presented, which includes the existing additive models as its special case. Existence and uniqueness of solutions to the model under some weak conditions are investigated. This study provides a powerful tool to further explore the traffic network equilibrium problem in a general situation.
