摘　　要：为了提高智能交通运输平台的运行效率,提升用户对路径规划、选择结果的满意度,针对当前路径选择模型中存在的路径规划时间较长、路径选择结果的可接受性较差等弊端,提出基于主客观权重的智能交通平台运输路径最优选择模型。利用层次分析法、定性分析与定量分析对用户主观偏好信息的权重进行度量,采用信息熵权法对道路的各项客观属性权重进行计算。结合归一化方法计算路径选择的主、客观组合权重,综合考虑用户对于不同路径的差异化评价指标权重,得到用户决策矩阵。将决策矩阵与非线性函数相结合,构建路径规划、选择模型,根据各规划路径的综合决策值排序获取最优路径。实验表明,所构建模型的运行效率高于实验对比方法,路径选择结果优于其它方法。In this article,a model to select the optimal route of intelligent transportation platform based on subjective weight and objective weight was presented.Firstly,the analytic hierarchy process(AHP),qualitative analysis and quantitative analysis were used to measure the weight of subjective preference information of user.Secondly,the information entropy weight method was used to calculate the weight of each objective attribute of road.Thirdly,the normalization method was used to calculate the combination weight of subjectivity and objectivity of path selection.In addition,the user decision matrix was obtained by comprehensively considering different evaluation weights for different paths.Moreover,the decision matrix was combined with the nonlinear function to build the path planning and the selection model.Finally,the optimal path was obtained based on the sorting of comprehensive decision value of each planning path.Simulations prove that the proposed model has higher efficiency and better path selection result than other methods.
