双参数下的随机用户平衡分配模型及算法

Stochastic User Equilibrium Model and Algorithm Based on Two Parameters

在考虑现实生活中用户对交通信息认识程度不一致的基础上 ,研究了双参数下的随机用户平衡分配问题 ,给出了等价的数学规划模型 ,证明了模型解的等价性与惟一性 ,设计了求解算法 ,并用算例进行了计算分析 .

Considering the inconsistence of user's knowledge of traffic information in real life,this paper studies the assignment problems of stochastic user equilibrium under two parameters and presents an equivalent mathematic planning model,which proves the equivalence and uniqueness of the resolution to the model,designs a correspondent resolution algorithm and carries out computation by the algorithm.
