Setting Position And Main Line Of Linear Indicators Research On Highway Main Line Toll Station

At present,with the improvement of the expressway network and the connection of expressway management,the main expressway toll station mainly set on the inter-provincial main line,and part of the main expressway toll station set on manage independent sections.Because of our province-based investment and business management model exists,the main expressway charges will be long-term existence.China's norms about the main expressway toll station were less and were short of the guidance theory in the engineering practice,so it is significant to study the main expressway toll station location and the main line of linear indicators.Based on the analysis of the relevant data,the paper summarizes the research status about domestic and foreign highway main line toll station,and analyzes the factors about boundary division;the technical indicators of main line;the minimum clearance of the structure;terrain;objects;the pricing model of development trend and other factors,finally summarized the flow chart for determining the location of the main line toll station.Based on the study of the location of the main line toll station,according to the basic theory of safety line of sight and vehicle dynamics,the linear index of the main toll station is analyzed,and the author establish the main line toll station at the level,vertical and horizontal indicators of the calculation model based on the existing basic model,finally,proposes the main line toll station line indicators recommended value.Based on the temperature rise model of the truck brake on the long section of the long section,the safety problem of the main toll station in the continuous downhill section is studied.The restriction condition,setting position and setting method of the main line toll station are put forward.Through the analysis of drivers between the mainline toll stations with the structure of the driving behavior,and fully considered the judgment and decision about driver driving process,according to the net distance factor and the basic model,the distance between the main line toll stations and the buildings,the distance of the road,the distance of the driver,the distance of the sign recognition process and so on were studied.Then establish minimum net distance calculation model between the main line toll stations and tunnels,interchange,service area,parking area and other structures.Finally,according to the calculation model proposed under different combinations of the main station and the construction of the minimum distance between the recommended distances.
