(57) The invention deals with the field of systems for detecting the position in which
a road accident occurred along ordinary roads, and in particular along motorways.
The system provides for the installation, along guard-rails or barriers made of reinforced
concrete (1), of an electric circuit or a circuit for emitting a signal (2) placed
in order to be easily interrupted by a motor vehicle impact. The circuit interruption
activates a processor (3) that processes electric data to determine the accident position
and transfers these data to signalling circuits.
The signalling circuits can be of two types: signalling circuits (4) along the road
route being surveyed, signalling circuits (5) located in assistance departments such
as Traffic Police Stations, Fire Brigade Stations, First Aid Stations, etc.
