Simulation Analysis Of Human-vehicle Accident Based On Multi-information Fusion

Pedestrian-automobile traffic accidents account for a large proportion in road traffic accidents.In human-vehicle accidents,the pedestrian casualty rate accounts for a large proportion in all traffic accidents,while human-vehicle accidents are always in people's attention.The research on the reconstruction of human-vehicle accidents and the analysis of accident mechanism have always been the focus of many scholars in the field of automobile safety.The application of computer simulation technology in traffic accident reconstruction is characterized by low cost,high degree of reduction and strong objectivity.It is widely used in accident identification,automobile safety design,damage biomechanics and other research fields,and has a strong reference value.Moreover,the research on the reconstruction of human and car accidents is of great social value.This paper studies and analyzes the current situation of the in-depth investigation of human and vehicle accidents in various countries,and sorts out and analyzes the human and vehicle accidents collected in the National Automobile Accident In-depth Investigation System over the years,so as to have a relatively accurate understanding of pedestrians,such as vulnerable groups,and to analyze and introduce in detail the types of road sections that are prone to accidents.Then,the characteristics of pedestrian traffic behavior are summarized,the accident reconstruction is carried out under different investigation conditions,and two real accident cases are taken as reconstruction simulation examples to discuss the applicability and errors of EDR technology,surveillance video,on-site traces and other information.In this paper,the technical methods of reconstructing human-vehicle accidents under different conditions are put forward.Combined with real cases,the simulation method is applied to complete the reconstructing process of accidents.According to the depth of information acquisition,combined with the simulation results for analysis,by adjusting the vehicle and pedestrian parameters,many times of simulation,simulation results more accurate,to verify the feasibility of the human-vehicle accident reconstruction method.
