Research On The Right-turn Traffic Organization Optimization At The Major-minor Intersection

With the development of social economy，more and more practitioners to realizethat traffic must rely on traffic organization to improve the accessibility and thesecurity of urban road network. The intersection is the key to influence the clear onthe network nodes. From the finest point，this paper does the research on themajor-minor intersection, which is one kind of small and medium-sized intersectionwith less study，by means of the intersection traffic organization optimization toimprove road traffic capacity，so as to achieve the aim of improving clear on thewhole urban road network.In this paper，the traffic turning process at major-minor intersection is as themain research object，especially for the right-turn traffic flow analysis. The entropymodel is established on the basis of the state discrimination of the right traffic of themain road, and then the corresponding method of right-turn traffic optimization is putforward. The main contents of paper are as follows:(1) Through literature reading，summarizes the commonly used at present theintersection of the contents，methods and steps of traffic organization，and put forwardwhat methods can be applied to the major-minor intersection traffic organization.(2) Respectively，from the left，right-turn traffic intersection highly channelizingmethod，set the lanes，etc to carry out the review analysis，the commonly used left，right-turn traffic organization method of the system，has been clear about the nextright-turn on the traffic flow of traffic organization study goals.(3) The research of traffic state about turn right traffic on the intersection of themain branch. By comparing the urban road traffic system and thermodynamic systems,the paper apply entropy to the field of traffic flow, and on the basis of the theory oftraffic flow to establish a fluid entropy production model. The paper analysis thenegative entropy and determine its significance injected designated state, andestablish a master-the total entropy model slip interchanges traffic system, to obtaintraffic state identification entropy model and need to inject negative entropy conditions. The results show that the entropy value, the higher the level of roadservice.(4) On the basis of traffic state discrimination about turn right traffic, the paperresearches turn-right traffic for traffic optimization organization. This paper base onthe pluggable car gap theory to make the model, comparative analysis of trafficcapacity, delay and other aspects about turn right, turn-right way ahead traffic. And itdraw a right turn is an effective measure in advance of the main branch of intersectiontraffic organization conclusions.
