摘　　要：Ｗａｒｄｒｏｐ用户均衡ＵＥ交通分配方法是城市交通规划实践中广泛应用的交通分配方法，然而，该法并不适用于我国机动车与非机动车混合行驶的城市交通规划。因此，根据机动车与自行车交通流之间作用机制的解释，建立了混合式ＵＥ分配模型及其算法。这个模型，已证明等价于ＷａｒｄｒｏｐＵＥ原则，其解又具唯一存在性，对于混合交通情况，是正常ＵＥ模型的扩展。最后，介绍了仅有两个路段的简单交通网络的混合均衡分配程序。The Wardropian UE(User'S Equilibrium)traffic assignment method is a predominant one used in urban road network planning practiaces, however, it is not suitable for Chinese mixed urban traffic networks containing vehicle and non-vehicle traffic flows. Therefore, a mixed deterministic UE assignment model and its algorithms are developed based on the interpretation of the reacting mechanism between vehicle and bicycle traffic flows in this paper. This model, whose uniqueness and equivalance to the Wardropian Principle of UB are also proved, is an extension of the normal UE programming model to the case of mixed traffic. Finally, the mixed equilibrium assignment procedure of a simple traffic network which contains only two links is presented.
