The LED signaling device is mounted on the L-shaped support - 7 to a height of 4.0 to 7 meters or more (depending on the conditions and requirements of the carriageway), is installed on both sides of the carriageway within the boundaries of one pedestrian crossing. The direction of the optical axis of radiation of the main element of the device - LED signal board - 1, parallel to the axis of the roadway. For maximum efficiency, the LED signal board - 1 has a two-way signal indication (in opposite directions of cars on the road), which provides drivers of opposite directions visibility of the board over the road, or one-way signal indication (for one-way cars on the road).

The LED signaling device has two operating modes: 1.) standby mode (static); 2.) response mode (dynamic).

1) Standby mode (static): in which the device is in standby mode of an object or objects (pedestrians) intending to cross the carriageway in the area of unregulated pedestrian crossing. At the same time, the elements: LED signal board - 1, sound emitter - 3, and LED projector - 5 are not active (i.e. they are in standby mode for activation signal). In contrast, in static mode, the following elements are active: a passive detector - 2, which continuously monitors the detection zone of the object in the area of the supposed pedestrian (pedestrians) carriageway, according to the parameters of the pedestrian crossing (width of the pedestrian crossing, configuration of the sidewalk and carriageway junction). The control unit - 4 - is active in both modes of operation of the device, because is one of the main elements of the operation of the entire device, it implements (control) the interconnection of the elements of the device according to the programming parameters. The photovoltaic solar module - 6 - is active, it is the main (additional) power installation of the device. In parallel with the accumulation of charge in a high-capacity battery during daylight hours, in static mode it feeds the control unit - 4 and passive detector - 2. In the dark - the elements of the device are powered by a rechargeable battery, or from a traditional source of energy (electric networks) depending from the embodiment of the LED signaling device - (the photovoltaic solar module is the main or additional power source of the LED signaling device).

2) Response mode (dynamic): an object or objects (pedestrians) intending to cross the carriageway in the unregulated pedestrian crossing zone fall into the control zone of the passive detector - 2. The signal from the passive detector - 2 is fed to the control unit - 4, which, in In accordance with a given program, it sends an activation signal to the LED signal board - 1, the sound emitter - 3, the LED spotlight - 5. These elements: the LED signal board - 1, the sound emitter - 3, the LED searchlight - 5 are activated in correspondence with the program of the control unit - 4 and the time determined by the settings works. The activation time (first cycle) of the elements: LED signal board - 1, sound emitter - 3, LED spotlight - 5, calculated by the time the roadway intersects in the unregulated pedestrian crossing area by an object (pedestrian) or a group of objects simultaneously in one direction, perpendicular to the axis of the roadway , at a speed of 0.3 m / s, with an additional margin of activation time of elements equal to 30 s (to exclude a critical transition point, when object A (pedestrian), completing the intersection of the carriageway, at the same time he is in the control zone of the passive detector - 2, with object B (pedestrian) intending to cross the carriageway in the opposite direction to the movement of object A). In the case when at the moment of activation (first cycle) of the device elements the LED signal board is 1, the sound emitter is 3, the LED spotlight is 5 (i.e. at the moment of crossing the object (pedestrian), or a group of roadway objects in the area of unregulated pedestrian transition), passive detector - 2 additionally detects one or a group of pedestrians in the detection zone of the object (intending to cross the carriageway in any direction perpendicular to the axis of the carriageway in the pedestrian crossing zone), then the element activation mode This is the LED signal board - 1, the sound emitter - 3, the LED spotlight - 5 is extended, and the countdown of the additional activation time (second, third ... etc. cycles) of these elements is taken from the moment the passive detector - 2 of the last from objects (pedestrian) or a group of objects. The duration of activation subsequent to the first cycle is similar to the activation time of the first cycle. After the last activation cycle, the LED signaling device enters the standby mode of the object. The control zone of the passive detector - 2 is selected according to the parameters of adjoining the sidewalk to the carriageway (to exclude accidental operations), and is regulated by the internal settings of the passive detector - 2.

The LED signal board - 1 at the time of activation, according to the signal from the control unit - 4, works in the mode of cyclic inclusion of light indication (1 on / 0.7 sec.). Light indication ATTENTION! PEDESTRIAN, made in the form of two lowercase inscriptions from the letters of the Russian alphabet consisting of superbright wide-angle yellow LEDs. The height of one letter of the inscription is from 150 to 220 mm (depending on the category of road, visibility and other conditions on the roadway). The advantages of LED indication allow using the LED signal board - 1, especially efficiently, in difficult weather conditions (fog, snowfall, rain, etc.) and in the dark. Sun visors allow you to minimize glare from the sun during daylight hours.

Sound emitter - 3 at the time of activation by a signal from the control unit - 4, operates in the mode of cyclic inclusion of sound radiation (1 on / 0.7 sec.). Sound emitter - 3 is designed to attract the attention of a pedestrian (pedestrians) when crossing the roadway in the area of unregulated pedestrian crossing. It signals a pedestrian or group of pedestrians about being in the danger zone of the carriageway.

LED spotlight - 5 at the time of activation by a signal from the control unit - 4, operates in a constant mode for a full cycle (cycles) of activity of the device. LED floodlight - 5 is highly effective in conditions of insufficient visibility (fog, snow, rain) and in the dark.

The main advantages of using an LED signaling device are:

- informative: the LED warning device informs the driver approaching the unregulated pedestrian crossing not only about the presence of a pedestrian (pedestrians) on the carriageway, but also about the intention of the pedestrian (pedestrians) to cross the carriageway in the unregulated pedestrian crossing zone.

- economic component: (the creation and installation of an LED signaling device will cost on average 40-50% cheaper than installing and installing a traffic light object, with comparable device efficiency), which will provide the possibility of mass application;

- environmental component: the operation of the LED signaling device (in contrast to the traffic light object) is carried out in the standby mode of activation, which, in the absence of pedestrians, reduces the likelihood of unreasonably slowing down traffic flows in urban conditions (traffic jams) and, as a result, reducing the amount of polluting emissions into the atmosphere ;

- psychological factor: (a device installed on sections of roads in the area of unregulated pedestrian crossings will attract the attention of road users by reducing the "addiction effect" to the road situation, and also increase the information content of the road, and as a result, reduce the risk of accidents) ;

- resource component: activation of the carriageway at the moment of a pedestrian crossing will ensure minimum energy costs when powering the device from the mains, and the use of solar panels, both in suburban routes and in urban conditions, eliminates the consumption of electricity from traditional sources;

- universality: the device can be used in conjunction with other safety features for arranging unregulated pedestrian crossings (artificial roughness, LED road signs 5.19.1 and 5.19.2, reflective elements, etc.), and is also suitable for use by visually impaired pedestrians;

- all-weather operation of the device;

- autonomy of the device (when using solar panels, it is effective to install on suburban roads with the lack of traditional power sources, as well as the operation of the device in the absence of electricity in the mains);

- the use of the device on the most dangerous section of the road will make it possible to evaluate the effectiveness of the complex in the shortest possible time (3-6 months).

The LED signaling device can be successfully used: at unregulated pedestrian crossings of public highways, at unregulated pedestrian crossings of suburban routes, with an intensity of 600 to 2400 units / hour; near schools and kindergartens, in the area of shopping centers and in other places of crowded people and cars (markets, squares, etc.); - on poorly lit sections of city roads and country roads and in difficult weather conditions (fog, rain, snowfall), as well as in conditions with insufficient visibility of the carriageway due to terrain elements (artificial road structures); at highly emergency unregulated pedestrian crossings.
