The Fuzzy Evaluation of the Signalized Intersection Service Level under Ice and Snowfall Conditions

Liu Chunxiao, Zhang Yaping, Cheng Guozhua, Zhang Hong


Ice and snow is common in the south of China, the operating efficiency of the transportation network under ice and snowfall conditions is quite different from under the normal condition. On the present service level evaluation system basis, the paper establishes the index system of the fuzzy evaluation of the signalized intersection service level under ice and snowfall conditions by AHP, and establishes the evaluation model of the signalized intersection service level under ice and snowfall conditions on the basis of fuzzy evaluation. Finally, we set an intersection of Harbin as the example to make a comprehensive evaluation of the signalized intersection service level under normal and ice and snowfall conditions to validate the efficiency of the model.
