The Research Of Road Traffic Fatal Accidents In Kunming Based On PC-Crash

In This study,about 41632 cases of road traffic fatal accidents was collected through Google,CNKI and other academic search engines,and about 998882 cases of road traffic fatal accidents was obtained on the official website of National Bureau of statistics(http://data.stats.gov.cn).Based on the analysis of the death cases of road traffic accidents in China,the general situation of the dead,the time of accident,the type of injury,the cause of death,the relationship between the cause of death and vehicle type,vehicle type,road type and accident type were statistically analyzed by SPSS 23.0 software.Also,through a large number of field investigations,the data of traffic fatal accident cases in Kunming were collected and analyzed,and the real human-vehicle collision database in Kunming area was established.The collision morphology and location of the accident,the characteristics of driver,vehicle and pedestrian in the pedestrian vehicle collision accident,the pedestrian injury mechanism and pedestrian injury evaluation index were studied.About 15 cases of road traffic accidents are reproduced by PC-Crash,and the collision model between pedestrians and the vehicles is established to simulate the real process of accidents.Through a large number of road traffic accident case studies,this study found that the time of accident,the type of injury,the cause of death,the type of vehicle,the type of road surface and the type of accident have certain characteristics.It further clarifies the law of road traffic accidents,which can improve the efficiency of forensic traffic accident prevention and identification and reduce the incidence of accidents students have an important reference role,but also provide a direction for the prevention of road traffic accidents and forensic research.The research shows that the road traffic accident virtual reappearance technology based on PC-Crash software has the characteristics of simple modeling,short simulation time,high reproduction accuracy,vivid simulation interface and easy extraction of analysis results.The application of PC crash software can reconstruct the road traffic accident caused by human vehicle collision,reproduce the scene of road traffic accident,determine the accident speed,and the location,degree and mode of injury were further clarified,which can provide new solutions to the problems of speed identification,injury mechanism and traffic mode for forensic expert.
