为解决动态不确定性交通网络中的路径选择问题,面向交通网络的不确定性特点,提出了一种考虑驾驶人个性化需求的路径选择方法。研究了不确定型多属性决策方法;在不确定型多属性决策框架下,构建路径综合评价指标体系;考虑驾驶人个性化需求的复杂性和模糊性特点,引入模糊分析方法进行指标权重的个性化确定;针对路网信息的不确定性,采用不确定型多属性决策方法对可行路径进行排序,从而得到最优路径。结果表明:该方法获得的最优路径既考虑了交通网络的不确定性因素,又充分体现了驾驶人的出行意愿。
In order to solve route selection under dynamic uncertain traffic network condition, a route selection method with personalized demands of the drivers considered was proposed for the uncertainty of traffic network. The uncertain multi-attribute decision-making method was studied, and the comprehensive evaluation index system of the route was constructed under the framework of uncertain multi-attribute decision-making. The personalization of index weight was defined by fuzzy analysis and with the complexity and fuzziness of the drivers' personalized demands considered. The optimal route was achieved, according to sequencing feasible routes by uncertain multi-attribute decision-making method for the uncertainty of traffic network information. The results show that the selected optimal route with this method considers the uncertain factors of the traffic network, and fully reflects the drivers' travel wishes.
