![]() The length of the skids established that the Toyota driver applied maximum braking for only about half a second before impact. Combining the physical evidence from the site inspection, the EDR data from the Scion, and the simulation results, the speed of the Toyota at impact was found to be approximately 18 mph.įactoring in the skid marks leading to impact, the Toyota was traveling at about 30 mph when the driver started braking. Vehicle Accident Simulation Software Just last week, someone asked me, how do you draw an accident report Then today, my brother asked me, how do you sketch a road traffic accident Is there any accident reconstruction app available out there It seems people are getting into car crashes and need to look for car accident diagram templates. The simulation calculates the motion of the vehicles using mathematical models of vehicle dynamics and impact mechanics. ![]() The Scion was completely stopped for about 0.5 seconds before impact.Ī computer simulation of the crash was prepared to establish the impact speed of the Toyota. The driver had the brake applied, and therefore the brake lights illuminated, for at least 5 seconds before the crash. Delta-V is the vehicle’s cumulative change in velocity over the short duration of the collision and is a quantitative measure of the crash severity.Īnalysis of the data established that the Scion slowed normally and came to a stop from an initial speed of about 20 mph over the 5 seconds prior to the crash. ![]() The data also included the delta-V measured by the vehicle’s ACM. The EDR data from the Scion started approximately 5 seconds prior to the crash, detailing the vehicle’s speed and driver inputs leading up to the impact. ![]()
