In-depth Analysis Of Collision Accident Of Vehicle And Two-wheelers And Research On The Influence Weight Of Accident Reconstruction's Parameters

With the rapid development of China's economy and the improvement of people's income level,our auto industry obtained the rapid development.Meanwhile,the traffic jam is getting more and more serious and the road traffic accident rate keeps rising because of the sharp increase of the number of automobiles.Two-wheeled vehicles(including motorcycles,electric bicycles and bicycles)are very popular among mass people in China because they are flexible,convenient,economical and energy-saving.However,the collision accident rate of two-wheelers has increased greatly in the mixed traffic mode.Riders on two-wheelers are the vulnerable persons in accident.In this case,researches on how to protect the riders on two-wheelers and on collision accident reconstruction of vehicle and two-wheelers have become research hotspots both at home and abroad.This paper adopts the research method of combining the analysis of the accident scene and computer software simulation.The research on collision accident reconstruction of vehicle and two-wheelers can be carried out in terms of accident scene survey,the calculation of collision speed,the influence weight of collision system's parameters and the computer simulation.Meanwhile,through in-depth analysis of the collected sample data,the statistical law of collision accident of vehicle and two-wheelers can be obtained.At first,this paper summarizes the research status of the traffic accident identification both at home and abroad in terms of accident scene survey,accident process reconstrcution and analysis of reconstruction result.Then this paper analyses the existing problems at present,and presents the main content and the technical route.Besides,this paper does some research on the investigation method of collision accident of vehicle and two-wheelers,designs a complete investigation process about accident scene and describes the investigate step detailedly combined with the actual accident case.By means of the method of logistic regression,this paper makes an in-depth analysis of the collected sample cases and thus obtains the correlation between information parameters of accident characteristics and injury severity of riders on two-wheelers.Additionally,this paper researches the application of uncertainty theory in collision speed calculation of vehicle and two-wheelers,and then the calculation and evaluation of the collision speed of vehicle and two-wheelers are made in a real collision accident case of vehicle and two-wheelers.Moreover,the influence weight of the collision accident reconstruction's parameters is ranked by means of PC-Crash;By reference to the influence weight order,we can adjust the input of information parameters in PC-Crash so as to obtain more accurate rescontruction results.Finally,by rescontructing three real collision accident cases of vehicle and two-wheelers,this paper verifies the validity of the accident reconstruction method of combining the accident site analysis and computer software simulation.The research result has guiding significance for treatment of collision accident of vehicle and two-wheelers and research on how to protect riders on two-wheelers from injury.
