随着人们生活水平的提高,对出行过程的要求也有了新的标准,而目前在单维度基础上进行的出行路径选择研究已经逐渐偏离出行者的真实需求。为了更好的满足出行者的出行需求,本文以前景理论为基础,从费用维度与舒适维度两个层面对路径进行综合考察,即在考虑感知费用的前提下引入舒适度函数,并分别以动态修正费用函数与舒适度修正函数为参照点进行收益与损失判定,在得到相应前景值后,根据用户对出行过程的费用与舒适度偏重系数计算出路径综合前景值,并以此作为路径选择的判定基础。最后通过一个具体算例对模型进行验证与分析,结果显示相对于单维度的路径选择模型双维度判断更符合实际。
With the improvement of people’s living standards, there is a new standard for the requirements of the travel process. At present, research on travel route selection based on the single dimension has gradually deviated from the real needs of travelers. In order to meet the travel demand of travelers better, based on the theory of prospect, this paper makes a comprehensive investigation of the path from the two dimensions of cost dimension and comfort dimension, that is, the comfort function is introduced under the premise of perceived cost, After the corresponding foreground value is obtained, the comprehensive foreground of the path is calculated according to the cost and comfort bias coefficient of the user during the travel process, and the path cost is selected as the path Judgment basis. Finally, a specific example is used to verify and analyze the model. The results show that the two-dimensional model is more realistic than the one-dimensional path selection model.
