摘　　要：针对实际交通网络中交通配流不仅考虑路径的选择,还要考虑交通方式选择的问题,研究了单起点时的动态交通私家车与公交车的方式划分与配流模型,证明了该模型一阶条件等价于瞬时的DUO条件和方式划分logit函数。To deal with the problem that not only the choice of path but also the choice of transport modal need to be considered in a traffic assignment of an actual traffic net, the model of mode split and assignment of dynamic traffic for single staring point family vehicles and buses is put forward. It is proved that the one-order conditions of the model are equivalent to transient DUO conditions and mode split LOGIT function

关 键 词：动态交通 方式划分 用户平衡
