| Nowadays,safety is an important research topic.Among them,traffic safety is also an important part.The game behavior between pedestrians and drivers is one of the important factors that affect traffic safety.Because of the particularity of people,people can not always choose the best strategy in the selection process,so using evolutionary game theory to study the strategy selection of pedestrians and drivers through the intersection is a very suitable research method.Firstly,this paper studies the relevant literature to understand the characteristics of pedestrians and drivers passing through the intersection,as well as the related concepts and theories of evolutionary game theory,and analyzes the applicability of evolutionary game theory to pedestrians and drivers passing through the intersection.Next,starting from the current situation of pedestrians and drivers passing through the intersection,further analyze the current situation of traffic safety at the intersection in China,further understand the relevant national laws and regulations and the control strength of relevant departments,and analyze the impact of the relevant national laws and regulations and the control strength of relevant departments on the pedestrians and drivers passing through the intersection It provides a solid practical foundation for the establishment of the model.Then two models are established according to the evolutionary game theory: the first model is the evolutionary game model of two groups of pedestrians and drivers at intersections without traffic signals,and then based on this model,we can get the strategy that in most cases,two groups of pedestrians and drivers tend to choose(compete,compete)through intersections without traffic signals;the second model The model is based on the first model,adding the relevant national laws and regulations as well as the control influence of relevant departments(that is,the relevant government departments set up the control of traffic signals and the actual participation of the relevant government departments),establishing the evolutionary game model of the three groups of the government,pedestrians and drivers through the intersection with the participation of the relevant government management and control.At this time,four different situations can be obtained:(1)when the difference between the safety benefits of pedestrian cooperation is greater than that of driver cooperation,and the difference between the safety benefits of driver cooperation is greater than that of pedestrian cooperation;(2)when the difference between the safety benefits of pedestrian cooperation is greater than that of driver cooperation,and the driver cooperation is safe When the difference between the benefits is less than the safety benefits only brought by pedestrian cooperation;(3)when the difference between the benefits of pedestrian cooperation is less than the safety benefits only brought by driver cooperation,and the difference between the benefits of driver cooperation is less than the safety benefits only brought by pedestrian cooperation;(4)when the difference between the benefits of pedestrian cooperation is less than the safety benefits only brought by driver cooperation,and The difference of driver cooperation safety benefit is greater than that of pedestrian cooperation.Then the MATLAB software is used to evaluate the simulation analysis,and the influence of the change of parameters on the final evolution results is studied.Finally,through the evolutionary game results of the evolutionary game model,this paper puts forward corresponding suggestions for the development of the government,pedestrians and drivers through the intersection. |
