Vehicle environment and road context




                 A/ ROAD CONTEXT
     Généralités  Types of roads



                The road network is made up of different types of roads: main network and secondary network (departmental, municipal roads, etc.).
                These roads can be unidirectional or bidirectional.
                Accidents can occur in a straight line, in a curve, at a circular point....




                               The type of road will determine how to access the interven-
                               tion area




                               The type of road will determine the positions of the vehicles
                               and the signalling methods to be used



               Topography of the site


                 Traffic accident management will be impacted by the topographical configuration of roads (slopes, ditches, ravines...)






                                     The topography of the site will impact vehicle
                                     stabilization methods and techniques for rescuing
                                     victims







              Construction
     GUIDE OPÉRATIONNEL DÉPARTEMENTAL DE RÉFÉRENCE / INTERVENTIONS D’URGENCE SUR LES VÉHICULES

              Many constructions line the road network (tunnels, bridges, electric lines...).






                                  The constructions will impact access, immobilization
                                  techniques, lighting and victim protection.







               Weather / Period of the day





                                  Weather will impact victim protection techniques
                                  and marking methods



                                  A nocturnal intervention will require the instal-
                                  lation of lighting equipment in the area but also
                                  specific lighting (interior of the vehicle, obstacles
                                  in the area,.....)
