Research On The Route Scheme Of Shenmi Expressway From Jiaxian To Mizhi

In order to better reflect the characteristics of expressway route,the traffic forecast,the technical standard demonstration,the end point of the study,the choice of the corridor belt to the highway Route program was studied combined with "God rice line to the rice to Expressway route program".According to the historical traffic data of the proposed project,the traffic volume and traffic characteristics are analyzed.Based on the economic situation of the relevant areas in Yulin,the socioeconomic indicators of the project area are forecasted.According to the dynamic link between economic development and transportation,the traffic occurrence volume and the traffic suction volume are forecasted.Based on the gravity model,the distribution of the induced traffic volume in the project area is forecasted.Then results are distributed to the annual road network and the traffic distribution of the regional road network is predicted.And then from the route corridor with the line selection principle as the starting point,the corridor with the principle of line selection,Huang map plateau area selection principle was studied.Then Taking the course of the highway Jiaxian to Mizhi section as an example,the comparison is made to the corridor zone of the Huangpu Plateau.According to the function of the highway and the role of the road in northern Shaanxi to determine the technical standards and the end of the project.Finally,the K-line corridor zone and the C2-line corridor zone of the project are analyzed and compared.According to the engineering geology and the number of projects,the possible corridor scheme is analyzed.
