摘要
针对出行者路径选择时对路段行驶时间的模糊性认识 ,通过模糊统计试验得出路段的隶属函数形式 ,采用“重心法”将模糊分布隶属函数中的模糊数非模糊化 ,并应用模糊聚类分析将哈尔滨市部分干道路段分类 ,选取模糊时间修正系数 ,修正多路线概率分配模型中的路阻函数 。
According to travelers' fuzzy reorganization to travel time when selecting routes, subject function of sections of roads is obtained through fuzzy statistic experimentations. Gravity method is adopted to change fuzzy data of fuzzy distribute subject functions into nor-fuzzy data, and fuzzy cluster analyzing measures is applied to classify some of the arterial roads in Harbin, by which to choose fuzzy time revising coefficients. Consequently, correcting road blocking functions which are in multi-routes probability distribution mode can prove the practicability of fuzzy random dynamic distribution model.
