RESEARCH ON DETERMINATION THE SPEED OF VEHICLES BEFORE AND AFTER CRASH USING PC-CRASH SOFTWARE

Abstract

In Vietnam, the method of determining the vehicle’s speed before crash on the basis of tyre tracks at the accident scene is applied. This method is presented a shortcoming when the tyre marks are changed due to the weather conditions or other external impacts that will result in incorrect results. This article presents the method of determning the speed of vehicles before and after crash according to the PC-CRASH software. The calculation model is built in the software with setting the vehicle's technical parameters in the case of oblique impact. Calculation results help to verify the effectiveness of the method which help the investigators to add methods to determine the speed of vehicles before and after crash in oder to improve the accuracy of the results.
