Study On Intersection Functional Area And Lane Characteristics

With the development of city construction and network density increasing,How to organize cross nodes of network traffic better is imminent.This article has focused on the intersection traffic lane on realization of functions,reasonable division,reducing interference from motor vehicles and slow traffic.Based on the analysis of the inside of the intersection traffic characteristics and the traffic conflict in the cross,this paper valued the influence of lane divided form,non-motor vehicles and pedestrians traffic organization.Besides,the principles and methods of traffic organization optimization is discussed,and put forward the design steps of the intersection traffic organization,and from the perspective of macro and micro two traffic organization at present commonly used method is introduced.Through the analysis of the relevant transportation theory and traffic problem,this paper combined with the existing traffic control method,control model,this paper proposes a new intersection turn around by setting the share of the lane and puts both of turn the car import way of the outside piece,and give the special phase,the turning vehicles and vehicle,slow down traffic for complete separation,on the one hand,to achieve the intersection of running separately,on the other hand,to eliminates the cross conflicts within the intersection.Thesis of xi 'an Cui Hua road and wild goose pagoda,example analysis and optimization of road intersection simulation to further validation of the proposed model,the intersection delay and maximum queue length is reduced,the overall intersection operation effect is the result of the improvement.In addition,this paper also researched the function of urban road intersection in detailed.Through the analysis of vehicles entering the intersection zone length,calculation model is put forward,and the function length recommended value under different design speed is gave,and to guarantee the functional areas are not destroyed in principle from all the key node of the zone length corresponding guarantee measures are put forward.
