Research on route selection of Jinrentong Expressway based on mathematical statistic methods
Expressway route selection is a highly technical,comprehensive,and complex task,and the traditional route selection methods heavily rely on the experience of professional route designers.This article studies the route selection process of the Shajiao Bridge section of the Jinrentong Expressway.Firstly,the traditional route selection method is used to compare the schemes,and it is concluded that the K-line scheme is superior to the B-line scheme.Then,two mathematical statistical methods,i.e.,BP neural network and grey correlation degree,are used to compare the route schemes,and the comparison results are consistent with the traditional route selection method.The results indicate that:1)Mathematical statistical methods have certain practical and validation value in express-way route selection,providing a new method and approach for the comprehensive comparison and selection of expre-ssway route schemes;2)Mathematical statistical methods can be used to assist in the selection and design of expre-ssway routes.
