| 摘 要： | 为有效解决路径选择行为中的不确定性问题，采用模糊逻辑方法建立路径选择模型。用三角模糊数描述路径行驶时间，并建立一定的模糊规则，然后，用近似推理方法两两对比可选路径，在对比矩阵基础上计算各条路径的权重，即路径被选择的概率。最后，对路径选择模型进行算例应用，验证了模型的有效性。

| Abstract: | In order to effectively address uncertainties in route selection behaviors, this paper establishes a route selection model using a fuzzy logic approach. Firstly, the paper defines travel time in terms of triangular fuzzy numbers, and introduces corresponding fuzzy rules. Given these fuzzy rules, a pair of available routes are compared with each other by a heuristic approximation, yielding the probability to select a route based on the weighting of each route resulted from the comparison matrices. A numerical example is included to illustrate the application oft.he route selection model. |
