Fuzzy user equilibrium traffic assignment model based on credibility measure

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.
