Currently,Guide lane organization planning that refers guide lane and guide arrows in this paper was accordance to relevant road's norms that Planning fixed and relatively single.It is difficult to meet the needs of different road traffic situations.Under normal circumstances when the vehicle enters the intersection,the driver want to reach their destination useing change lane,However,in the guide lanes organization,the guide lane line and the guide lane arrows area length were set unreasonblely,the vehicle was difficult to complete the change lane behavior,the driver may choose to slow down waiting for an opportunity lane change,Will lead to road clog and vehicle queues,this road conditions had a greater impact on traffic flow.This article based on cellular automata theory to establish numerical model(Road parameters: the Signal setting type was that turn left and go straight were opened at the same time,turn ringht was not control by Signal linght)which analyze the inpact of guide line organization to traffic flow.The main article working as:First,by collecting data and read a lot of literature,discovery few scholars research traffic flow which influence by guide line organization.This paper,By cellular automata model simulating two road conditions(since the vehicle on the road changing lanes safe distance factor can not complete the lane change,the driver will stay in the fornt of guide line or continue driving,this two actual road status),analyze the impact of the guide lane organization on signalized intersection traffic flow.Then Comparison of analyzed under different traffic road conditions,the guide line and the guide arrows area length(The length was between the first guide arrow which from traffic light farthest and guide lane line)to impact of Intersections traffic flow.through statistical Analysis of average density,average speed,the number of parking and number of vehicle in the guide line that can not be completed change lane etc parameters,analyzed the range that guide lane line length and the guide arrow area length to ease the traffic pressure,improve the efficiency of road.This paper through the above research,as conclusions:The driver's stop in fornt of guide lane line at waitting for change lanes behavior,this driving behavior's has seriously hindered the safe driving of road vehicles and has a greater impact on traffic flow.Under different traffic,green ratio,as well as road steering ratio traffic condi-tions,different guide lane line length and the guide arrows area length varies had greatly affect on traffic flow,by setting guide lane line length and the guide arrows area length can make the vehicle run smoothly,and traffic flow distribute balance.By Curve fitting the number of parking and the number of vehicle in the guide line that can not be completed change lane parameters,show that under different traffic,green ratio,as well as road steering ratio traffic conditions relationship between these parameters and guide lane line length and the guide arrows setting distance.By Analysis of the relationship between the above parameters,you can adjust the number of number of parking and the number of vehicle in the guide line that can not be completed change lane,to reduce the road traffic pressure that can provide some reference value for road management department.
