Research And Improvement Of Traffic Accident Reproduction Technology In China's Traffic Environment

Traffic accidents are often happened in daily life,because each traffic accident has its own characteristics,therefore,in the traffic accident investigation shall be conducted according to the characteristics of crime scene investigation and related investigation and collection of evidence,the policemen will commonly use field exploration tool traces of traffic accident scene,collision vehicle bodywork traces of exploration,and then according to the results of the survey analysis of traffic accident causation,again on the parties,and the sources for questioning and inquiries,determined the final responsibility for the accident.As the complexity of traffic accidents increases,the difficulty of investigation and measurement error will increase correspondingly.In order to improve the accuracy of case investigation,both at home and abroad attach great importance to it,and have developed some special software tools to assist the investigation of traffic accidents,namely the reproduction technology to simulate traffic accidents,such as PC-crash.At present,the domestic research and development in this field is relatively late.According to the practicalapplication results,the reproduction simulation error is large and the vehicle model is not fully equipped,which is still far from the accuracy over 95% of such software in foreign countries.As a teacher of the police college,I found in the teaching process of this kind of software that there was no corresponding model for the domestic model,Chinese special model,Chinese special road traffic environment and other elements in the software,which led to the replacement of other similar models in the simulation process and increased the simulation error.In order to solve this problem and reduce simulation error,this paper,through a large number of actual data collection and research,adopts the method of combining increasing field data exploration and model design,adjusts the software model data to be basically consistent with the corresponding model,and conducts simulation comparative analysis through actual cases.Through the test of practical application,the expected effect of error reduction is achieved.At the same time,good results are obtained in practical teaching,which has great practical significance.
