Research On The Game Behavior Of Pedestrians And Motor Vehicles On Roads With Traffic Behavior Styles

With the rapid development of China's economy,the urbanization process is accelerating,and the travel needs of urban residents are also increasing.In recent years,the number of motor vehicles in our country has continued to increase,making limited road resources further occupied by motor vehicles.Under the rules of motor vehicle courtesy of pedestrians,the problem of rushing by people and vehicles has become more prominent,and the environment for pedestrians to cross the street has further deteriorated.The conflict between pedestrians and motor vehicles is becoming more and more serious.Therefore,the conflict between pedestrians and motor vehicles has become one of the hot issues in the field of urban road traffic safety in China.Considering the traffic behavior style of pedestrians crossing roads,the causes of human-vehicle conflicts are analyzed subjectively.Mathematical expression of the game behavior of motor vehicles,analysis of the evolution of the game between pedestrians and motor vehicles in road sections,and the construction of microscopic pedestrian traffic simulation models,etc.To reduce the occurrence of traffic accidents,strengthen the safety of urban residents' road traffic travel,and propose reasonable control Strategy has important practical significance.First,select representative pedestrian crossing sections to conduct on-site investigations,and conduct questionnaire surveys and video shooting investigations to grasp the traffic behavior styles of pedestrians crossing the street sections,to obtain data information such as traffic behavior styles,crossing speeds,and analyze the behavior of pedestrians crossing the street Characteristics,speed characteristics,psychological characteristics;at the same time,the driver's driving tendency investigation is conducted to analyze the characteristics of the driver's crossing behavior.Secondly,analyze the influencing factors that affect the decision-making behavior of pedestrians and drivers crossing the street.The average delays of pedestrians and drivers are obtained from the video survey data.The risk and tension parameters of pedestrians and drivers are quantified and calibrated.Finding the subjective factors that cause conflicts between pedestrians and drivers across the street provides a theoretical basis for the construction of a human-vehicle game model.Thirdly,through game theory to analyze the evolution mechanism between pedestrians and drivers on the road,based on the assumptions of the model,the utility of decision-making behaviors of pedestrians and drivers across the street is analyzed,and the payment utility income function is established to construct pedestrians and drivers across the street.Game model in the case of human first decision.Discuss the game process between pedestrians and drivers in different traffic behavior styles,and verify the reliability of the human-vehicle game model.The section of the south gate of Shandong University of Technology,Xincun West Road,Zhangdian District,Zibo City was selected as the experimental route.The relevant data required for the investigation model were carried out on the spot to complete the calibration of the game parameters of pedestrians and drivers crossing the street.Finally,it analyzes the gains and losses of the game between pedestrians and motor vehicles in the evolution process,and proposes a reasonable control strategy to reduce the safety hazards of pedestrians crossing the street,with a view to improving the efficiency of motor vehicles crossing the street,and optimizing the traffic control system.
