<p>The telematic device for enhancement of road-traffic safety, particularly in connection with the movement of road maintenance vehicles and/or rescue vehicles (3) on highways or motorways, comprises variable road signs (4) located along the road at a specific distance in front of the critical traffic area, said variable road signs being controllable by means of a remote switch (5) installed inside a road maintenance vehicle and/or inside a rescue vehicle (3). The remote switch (5) is designed to control the variable road signs through the use of encoded radio frequency signals. Said critical traffic stretch is a sector of a highway (1) that is intended for turning of road maintenance vehicles and/or rescue vehicles (3). The variable road signs (4) are usually placed at two different distances in front of the critical traffic area, typically in the distances of about 300 meters and 600 meters respectively.</p> |
