Vehicle environment and road context
A/ ROAD CONTEXT
Generalities 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,.....)
