摘　　要：考虑城市交通中有多类出行者的一般情况,在ATIS等交通信息系统的影响下,不同类型的出行者对路径出行时间有不同理解,用不同的参数来反映.在此基础上,给出考虑路径选择、方式选择、讫点选择及是否出行的多类型随机用户出行决策模型,证明了模型的一阶条件满足路径选择、方式选择、讫点选择及是否出行的条件,最后给出模型算法.This paper considers multiple classes of travelers in general. But different travelers have different views on travel time for ATIS and other traffic information systems. It can be reflected by different parameters. On this basis, a stochastic user equilibrium model is presented. Travelers are grouped into different classes and they make decisions after taking lots of factors into consideration, such as routing choice, mode choice, destination choice and whether make a trip or not. Finally it is proved that the first-order conditions for this model satisfy them and an algorithm is given to solve the problem.

关 键 词：随机用户平衡(SUE) 路径选择 方式选择 讫点选择.
