A laser system that projects fans of blue, red, and green beams into the night sky is being tested on the M-4 Don highway near Krasnodar. The installation is designed to attract drivers' attention and help them maintain concentration behind the wheel. According to stated data, the light is visible from a distance of more than 3 km.
The idea is to highlight a section of the road with an unusual visual signal. At night, when monotonous surroundings can reduce vigilance, bright beams should make the driver pay attention to what is happening around and focus on driving.
Currently, the system is being tested on a limited section near Krasnodar. If the experiment shows a positive result, similar installations may appear on other federal highways. However, there is no data yet on how much laser signals actually reduce accident rates.
