摘　　要：在传统随机均衡配流模型的基础上,提出了一种增广的随机用户均衡配流模型及其求解算法。在此基础上构造了一个双层规划模型,用以描述基于随机用户均衡原则的从路段观测流量估计O-D交通量的问题,并给出了相应的求解算法。该模型及其求解算法对于解决O-D估计问题是可行有效的。In this paper, an augmented stochastic user equilibrium traffic flow distribution model and its solving algorithm are proposed based on the traditional stochastic equilibrium traffic flow distribution model and also a bi-level programming model is structured which is used to describe O-D traffic volume problem from the road segment observation flow estimation based on stochastic user equilibrium principle, and a corresponding solving algorithm is given. The new algorithm will be shown to be valid to solve O-D estimation problem by analysis some questions.
