考虑出行行为选择的模糊性以及可信性测度，同时兼顾可能性与必要性的优势，采用三角模糊数作为路段阻抗，建立了基于可信性的模糊多路径分配模型以及模糊用户平衡分配模型．以期望最短路为参照，提出了模糊有效路径的概念，给出了模糊多路径分配算法．在此基础上构建了模糊用户平衡分配的MSA算法．运用一简单算例进行了仿真试验，试验结果证明了模型与算法的有效性．

Considering the fuzziness of trip choice and advantage of credibility measure in dealing with the possibility and necessity simultaneously, the fuzzy multi-path and fuzzy user equilibrium traffic assignment model which take the triangular fuzzy number as impedance based on credibility measure are established separately. Using the expected shortest path as a reference, a concept of fuzzy efficient route is defined to design an algorithm which can solve fuzzy multi-path assignment problem, and a MSA algorithm is applied to solve the fuzzy user equilibrium model . Using a simple example, a simulation test is made and the result shows the efficiency of the model and algorithm.
