| 摘 要： | 系统地讨论了混合交通均衡（ＵＥ，Ｕｓｅｒ’ｓ Ｅｑｕｉｌｉｂｒｉｕｍ）配流问题．对于阻抗边际贡献对称型混合交通，笔者建立了与相应的Ｗａｒｄｒｏｐ均衡原则等价的极有小值模型，证明了极小值模型的等价性、解的唯一存在性，并讨论了具体求解算法；对于非对称型混合交通，直接给出了其均衡求解算法。最后，实现了一个简单网络的混合交通均衡分配。

| Abstract: | In this paper, the problem of mixed traffic equilibrium(UE, User'sEquilibrium) assignment is discussed systepeatically. In the case of the symmetricmarginal contributions to link travel times, a corresponding minimum program-ming model (equaling to the principle of Wardropian Equilibrium) is developed.The equality and uniquesness of the programming model are proved and thealgorithm is also derived. When the marginal contributions are asymmetric, wepresent a UE searching procedure directly. Finally, the equilibrium assignment ofa simple transportation network which contains vehicle and nonvehicle traffic isanalysized. |
