A speeding vehicle on a narrow city street enters the oncoming travel lane and collides with a vehicle heading in the opposite direction and causes severe injuries to the other motorist.  This simulation is from a case reconstructed by FCS and is based on crash Event Data Recorder evidence harvested from the speeding vehicle.  This EDR data made it possible to show the vehicle’s speed and steering leading to impact on the roadway.  Photogrammetry was also used to plot roadway evidence at the scene from police lapel video footage, which shows the location of impact on the roadway.  Our work incorporating the scientific and forensic evidence blew this case wide open and proved “who hit who” on the wrong side of the road.
