L'expertise des accidents routiers au sein du département véhicules de l'IRCGN

Most of the time, accident reconstruction is a transverse activity which involves different fields of forensic sciences. For instance, paint analysis establishing or not an interaction between several vehicles or street furniture, light bulbs analysis telling whether they were on or off when the accident occurred, onboard numerical data revealing the driver's last actions on the car, and so on. The accident expert oversees them all and has to interpret his colleagues' results to get factual parameters. By doing so, he is then able to propose a mathematical model to determine vehicles dynamic parameters at the time of the accident.
