Road safety - A new approach to assist road infrastructure managers

The S_VRAI project, sponsored by the DSCR, consisted in implementing 50 data loggers on public fleet vehicles, for a 12-month data collection. The purpose is to detect road incidents (potentially dangerous driving situations) from the main parameters characterizing vehicle dynamics. This research project allowed to: Develop a whole package to collect and analyze road incidents: industrialized material, database, data processing tools; Create an appropriate 'legal toolkit', including solutions to protect the personal data of drivers and obtain the CNIL authorization; Collect 3500 itineraries / 100000 km traveled, 1500 events, including 350 incidents; Identify risky areas on a road network; Show that road infrastructure played a part in 56 % of incidents in rural areas. S_VRAI benefited from the implication of the Departmental Council of Seine-Maritime. The relevant and operational character of this approach for a road manager is thus validated. Partnerships with new local authorities will allow the analysis of incidents on a larger scale.
