The Mechanism Of Lane Change And Its Influence On Intersection Capacity

The lane change is a common driving behavior in the process of driving on the road.It is influenced by driver factors,driving behavior,road conditions and natural environment.At the same time,lane change will affect the operation of traffic flow.The study shows that the lane change has a great influence on the traffic on the road.When the traffic density on the road is too large or too small,the behavior of the vehicle transformation will occur,but the frequency of the transformation is not high,and when the traffic is moderate More prone to lane change.In today's increasingly severe traffic pressure,it is necessary to analyze the relationship between lane change and road capacity,qualitatively analyze the traffic capacity at the intersection,thereby enhancing the traffic control measures and improving the smoothness and service capability of the road.Based on traffic flow theory,the factors influencing the driver's driving,traffic design theories and methods,etc,to study the driveway transform and cause relationship between traffic congestion,the concrete content just as follows:(1)Based on the driveway transform as a starting point,this paper analyzes the driveway transform conditions occur,and presents the transformation conditions,road conditions,driving conditions and gap establishes a minimum variable lane clearance,constructs the calculation model of the minimum variable clearance,analyzes the order of magnitude relationship between traffic flow and lane change,thus the happening of the driveway transform maximum probability was born in the condition of unsteady flow between free flow and the crowded flow,made clear the driver drive transformation driver factors,including gender,driving experience,age and psychological characteristics,etc.(2)The establishment of the evaluation index of drivers lane change,from the universality,controllability and risk analysis in three aspects,studies show that in illegal behavior,the greatest impact on road traffic safety,the need to establish the lane change behavior and main influence factors,it analyzes the formation mechanism for the driver that is established for road and replaced the game between evolution model,from the point of view of earnings,setting a Nash equilibrium solution,using the angle of economic analysis in the game result of payment(3)For driving people in crowded conditions,different lane-changing behavior were analyzed,and puts forward three types of lane changing conflict,namely inclined plug type,extrusion type and parallel type,established under different congestion pressure coefficient,the proportion of the driveway transform,the qualitative analysis of lane changing type and congestion of quadratic linear relation between pressure coefficient,different traffic conditions are given,taking in the best behavior.(4)Research on the calculation model was established at the intersection of the vehicle to change the road capacity,the basic data in the full investigation of road information,traffic signal timing,etc.,through the calculation,the error comparison between data and the actual capacity of the theoretical model,to verify the validity of the model,and through VISSIM simulation.The delay data generation based on the queuing probability of intersection saturation and vehicle were calculated based on intersection capacity were analyzed.
