Simulation Of Mixed Two Wheels Traffic Flow Model Based On Cellular Automata

Two wheeled vehicle in this paper includes human bicycle and electric bicycle and motorcycle. In some city, in order to reduce the friction interference and accident after two wheeled vehicles and motor vehicles mixed, the relevant departments set up two wheeled vehicle lanes in the vehicle lanes on both sides. Due to human bicycle and electric bicycle and motorcycle have different basic characteristics such as driving behavior and speed. The mixed two wheeled vehicle traffic not only brings some problems to traffic management and control, but also may casr accidents. So, build a suitable traffic flow model to study the traffic characters of two wheeled vehicle flow and to analyze the reason of the generation of the traffic problem and put forward improvement measures is important.In this paper, the main research content is:Firstly, this paper studied the basic parameters of the two wheels, including two rounds of two wheeled vehicle’ size, speed, parameters such as proportion of travel, acceleration, braking distance.Then the two rounds of car cyclists ride characteristics and two rounds of mixed traffic flow characteristics are analyzed. On the basis of them, the introduction of the two wheels are the general rules of lane changing, honking lane changing rules of radical, lane changing rules, and coupled with the improved NS model, set up two rounds of mixed traffic flow cellular automata model car.At the same time, the proportions, the variables of the proportion of three kind of car has carried on the quantitative characterization.Studied the mixing coefficient and honking lane-changing behavior, radical lane-changing behavior on two rounds of the influence of the mixed traffic flow.Secondly, this paper establishes a kind of mixed with retrograde two-wheelers cellular automata model of vehicle basis on the two wheeled vehicle’s characters after retrograde vehicles mixed and considering the retrograde and forward vehicle follow different lane changing rules. Study the infulence of mixed traffic flow of the proportion of the retrograde car, and lane changing probability.Lastly to the phenomenon of people often across some place of the two wheeled vehicle, after analysis the characters of two wheeled vehicle and people in the conflict place, we build the mixed two wheels traffic flow cellular automata model model considering people across.Finally, through the virtual coil method of traffic investigation, and we use the traffic survey results of two rounds of traffic flow density-related data to compared with the above three kinds of model simulation data. the comparison of the results demonstrates the accuracy of the model.
