Abstract: FIELD: automated energy-saving control of lighting methods. 
     SUBSTANCE: invention relates to methods for automated energy-saving control of lighting of road sections powered by a centralized three-phase AC network or from renewable energy sources. The claimed method of energy-saving control of lighting of road sections consists in monitoring the level of natural illumination using light sensors installed at a certain distance on both sides of the illuminated section of the road, monitoring, using other light sensors, the approach to the illuminated section of the road of the vehicle with the devices turned on lighting, determining the direction of movement of the vehicle, at a level of natural illumination equal to or below the minimum set value at which it is necessary to turn on the lighting system of the illuminated section of the road, and, if the vehicle is moving towards the illuminated section of the road, turning on the lighting devices of the lighting system of the illuminated section highway, counting the specified time required for the vehicle to leave the illuminated section, control, using third light sensors, the vehicle's exit from the illuminated section of the road, including when it turns on the illuminated section and exits in the direction from which it entered, and, if the vehicle leaves the illuminated section of the road before the end of the specified time countdown required for its departure from the illuminated section, then the lighting devices of the lighting system of the illuminated section of the road are turned off, without waiting for the end of the specified time. If the vehicle does not leave the illuminated area for a given time, then after the end of the countdown of this time, it is concluded that the vehicle has stopped for a long parking in the controlled area or left it with the lighting devices turned off and the lighting devices of the lighting system of the illuminated automotive area are turned off roads, if, after a long parking in a controlled area, the vehicle turns on lighting devices, then the fact of this is determined using light sensors, installed in the area of ​​the illuminated section and, at the same time, if the level of natural illumination is equal to or below the minimum set value at which it is necessary to turn on the lighting system of the illuminated section of the road, turn on the lighting devices of the lighting system of the illuminated section of the road and again start the countdown of the time required for the vehicle to leave from the illuminated area, after the countdown of which or after the vehicle leaves the illuminated area before the end of the countdown of this time, the lighting devices are turned off. 
     EFFECT: increasing the functionality of the method due to the fact that the lighting equipment is turned on only if necessary, taking into account the possibility of stopping the vehicle in the illuminated area for a long parking, leaving it from the illuminated area with the lighting devices turned off and the situation when the vehicle makes a U-turn on the illuminated area and leaves for the direction from which it entered.
