Road safety is monitored along the year with feedback information transmitted by the police to the Prefectures concerning the number of injury and fatal accidents.
On the other hand, the analyses must be based on individualised files of injury accidents, known as Bulletins d'Analyse des Accidents Corporels (BAAC), consolidated each year by the local road safety observatories with the support of Cerema, ONISR publishes accident monitoring barometers throughout the year, and produces annually with the support of Cerema global, territorial or thematic analyses in the form of a compilation, the "Annual Road Safety Report".
