Right Turn Vehicles And Pedestrians Conflict Analysis And The Design Optimization

In the overall urban road,there may be conflicts between vehicles and pedestrians,which will lead to traffic accidents and bring negative impact on the safety of life and property of relevant personnel.At the same time,pedestrians and vehicles will not give way to each other,which may also cause adverse consequences such as traffic delay of the above two.This paper studies the design optimization of conflicting right turn traffic flow and pedestrian traffic.This paper first analyzes the impact of vehicle traffic changes caused by pedestrians passing through the intersection,and analyzes the possible traffic accidents caused by pedestrians passing through the intersection.The intersection of Weiyang road and Fengcheng No.7 road in Xi’an city is selected to analyze the basic pedestrian speed,vehicle turning time and headway,and then record the specific traffic situation of the above intersection by using video detection method.The tracker software is used as the data extraction software of traffic survey,so that the characteristics of pedestrian vehicle conflict at the intersection can be analyzed by fixed time and location Finally,a framework for conflict analysis between vehicle turn and pedestrian traffic is proposed.Based on the severity classification of pedestrian vehicle conflict and the number of impact indicators brought by the conflict,this paper starts with the establishment of risk assessment of Road intersection traffic,analyzes the related behaviors of pedestrians and vehicles,and obtains the relevant risk assessment under the condition of pedestrian vehicle conflict through computer software simulation and mathematical modeling Price value and the risk degree of conflict between people and vehicles.According to the impact of pedestrian vehicle conflict on intersection safety under different scenarios,four classifications of pedestrian crossing are proposed and verified by simulation.In this paper,the simulation software VISSIM is redeveloped by python,and through the comparison with the actual traffic situation,the relevant traffic conflict risk degree evaluation value is obtained,and the conflict risk degree proposed in this paper is demonstrated.Finally,according to the distance between the sidewalk and the parking line,the width of the sidewalk,and the related signal light group adjustment,the optimization scheme of reducing the pedestrian vehicle conflict at the intersection is obtained.
