The Analysis of the Key Problems about Traffic Accident Speed Identification Based on Braking Traces
In order to improve the impartiality and objectivity of judicial expertise,the key problems about traffic accident speed identification are analyzed and the speed of vehicle is calculated by using the braking performance test report with reference to the national standard and automobile theory.The automobile dynamics of driver braking process is analyzed,all kinds of key problems such as the braking distance,braking coordination time,braking speed,longitudinal sliding coefficient of adhesion are combined with the braking performance test report,and the method of determining the longitudinal sliding coefficient of adhesion is proposed,the instantaneous velocity before the collision is calculated.Finally,the method is used to calculate the speed of an actual case,and simulated in the software of PC-Crash,the results are consistent,verifying that the speed identification method is correct.
