Abstract:
The main consumer properties of the road are the ability to drive a vehicle at high speed, safety, and comfortable
traffic movement. The general trends in the automotive industry are such that the performance of the passenger car fleet
increases approximately every 7-8 years. At the same time, roads are modernized only every 20-30 years, while in Russia
this period is even longer for most public roads. It is important to determine what needs to be done on the roads in order to
increase the speed of modern passenger cars while maintaining safe driving conditions. From statistical data, it is known
that approximately 22-25% of the total number of road accidents are associated with unintentional exits of cars from the
roadway. The consequences of such accidents are particularly severe, accounting for 20% of deaths and a large number of
injuries, while the material damage is characterized by a significant deterioration of vehicles and goods transported. One of
the main ways to reduce the severity of these consequences and improve traffic safety is the installation of fencing devices,
which could retain the car, which has lost the driver's control, on the carriageway, and not just to retain the vehicle, but also
to exclude departure on an oncoming lane, reduce consequences from a road accident, and exclude fatal cases.
