多用户公交网络系统的随机平衡分配模型

本文考虑多用户情况下的公交网络系统的随机平衡分配问题，建立了与其相等价的数学规划模型，并提出有效的迭代算法．由于线路容量的限制，会导致乘客的过载延迟．在本文的模型中，乘客的过载延迟时间可由相应容量约束的拉格朗日乘子计算得到．最后，实例表明该模型和算法是合理的和有效的．

A STOCHASTIC TRANSIT ASSIGNMENT MODEL FOR MULTI-CLASS USERS

This paper proposes a stochastic user equilibrium assignment model for congested transit networks with multi class users. The corresponding equivalent mathematical programming problem is formulated, where the different perception of various user classes such as workers and shoppers on the path travel time is considered. An iterative algorithm is also put forward. Finally, an example is given to show that the proposed model and solution algorithm are rational and effective.
