Abstract:
In urban traffic network,when the attributes of times and costs for paths were confirmed,the path selection problems with the preferences of travelers or not were analyzed.When there were no preferences,the integrated attribute value of each path was obtained by using the information entropy theory and the multi-attribute synthetic decision method.When the preferences for different paths were given by using the reciprocal judgment matrixes,for obtaining the weight of each attribute,an optimal model of weight vectors was set up to minimize the deviations between the reciprocal judgment matrixes.The model was solved by the analytic method,the attribute weights were used to calculate the integrated values of the paths,and the path with the maximum was the optimal.Analysis result shows that for the no preference problem,path 2 is the optimal with the integrated value 0.918.Otherwise,for the preference problem,path 4 is the optimal with the integrated value 0.965.Under the two conditions,the orders of six chosen paths are different.So,the preferences of travelers have obvious effect on route choice.3 tabs,1 fig,13 refs.
