Analysis of road incidents collected by EDR

Résumé

The French government (DSCR) sponsored the S_VRAI project (Saving Lives through Road Incident Analysis Feedback) to answer the question: Can incident (namely dangerous driving situation) collection and analysis help to avoid accidents? A recording device designed by IFSTTAR-LMA, called EMMA, was used to detect situations during which the vehicle reaches high dynamics demands in longitudinal, lateral or combined directions. 50 EMMA were deployed for one year from autumn 2012 on public fleets in the North, Center and South of France. EMMA acquires data from internal accelerometers and gyro-meters, GPS trajectory and speed, and data available on vehicle CAN bus. The data are analyzed in real-time to detect when acceleration signals exceed some thresholds, modulated by vehicle speed. The data acquired 30s before and 15s after the trigger are then stored and sent automatically to a secured server. The data collection comprises also the itinerary paths and information illustrating the dynamic demands for each travel. All legal conditions to implement EDR were respected in accordance to European regulations. The whole data collection produced 3052 itineraries and 339 incidents (one every 340 km or 5 hours). 25% of the incidents concern longitudinal accelerations and 70% lateral, including 70% on right hand turns.
