Description

The invention relates to the field of traffic regulation of automobile traffic flows, in particular to traffic regulation in reverse lanes, pedestrian crossings, as well as intersections equipped and not equipped with traffic lights, to indicate the direction and signaling of traffic safety.

Known technical solution "Design of the marking of roads", RF patent for utility model No. 99013, IPC E01C23 / 16, publ. November 10, 2010. The essence of the claimed design of the marking of roads is that a transparent guide is placed on the axial line of the road, a flexible LED cord is laid in its axial slot, a groove is made on the edge line of the road, in which a flexible LED cord is laid and fixed which is powered by a DC or AC power source.

The disadvantage of this technical solution is that this marking is equally visible to all road users, and does not provide accurate visual information to vehicle drivers, namely, an indication of the direction and lane of traffic flow.

Known technical solution "System and method of traffic regulation", RF patent for the invention No. 2432616, IPC G08G 1/09, G08G 1/07, publ. 10/27/2011 The system contains road signaling devices made in the form of green light sources located along a section of a highway with the possibility of creating a green light line along a given section of a highway, visually informing car drivers about the need to start the simultaneous movement of cars on a given section of the automobile roads and providing the possibility of the simultaneous start of the movement of standing cars on this section of the road.

The disadvantage of this technical solution is that informing drivers of vehicles occurs with the help of signaling devices located along sections of roads, while it is not possible to inform drivers who drive in one direction, but on different lanes of the roadway. Each lane has its own permitted and prohibited directions, in this case, the driver is not clearly allowed direction of movement. Also, in this case, the driver receives information from the edge of the road, and in the conditions of the city this alarm is lost in a large number of advertising stands, monitors and signs.

An object of the invention is the regulation of traffic using light signals located on the surface of the roadway controlled differentiated road markers. Obtaining a light alarm directly from the surface of the road surface (where the driver’s greatest attention is directed) allows to simplify the recognition of the traffic light signal and the direction of movement, differentiated for each lane, and other road users.

The technical result is achieved by a device controlled by a differentiated road marker, which is installed in the surface of the roadway. Managed differentiated road marker consists of a housing in which a battery is installed, a control unit, a geolocation beacon, the upper part of the housing is made in the form of a solar battery and several light sources with lenses for refracting light rays, each light source being made in the form of light sources, red , green and yellow emission spectrum.

In fact, a controlled differentiated road marker is a light signaling device installed on the surface of the road surface and operating in the light signaling mode for four directions (or two, or three), and for each direction, corresponding to the traffic light mode of operation, or respectively allowing or prohibition signs. Despite the fact that the light fluxes do not intersect, and from each direction of movement only the signal that is intended for it is visible.

The control unit is connected to an external control center, by transmitting an encrypted radio signal, designed to switch and synchronize the operation of the entire chain of controlled road markers or a matrix of markers of a traffic light object.

The geo-positional beacon is intended for transmission to vehicles, over a short distance (not more than 1-1.5 m), the exact coordinates and the number of the strip on which it is installed. It is a radio transmitter operating at GPS and GLONASS frequencies, and transmitting only the exact coordinates and the number of the strip on which it is located.

The battery is designed to ensure the operation of the device at night.

The invention is illustrated by drawings, where in Fig.1 shows a structural diagram of a traffic light object with controlled road markers, Fig.2 shows the appearance of a controlled road marker (top view), and in Fig. Figure 3 shows an example of the location of guided road markers in lanes.

Managed differentiated road marker consists of a housing 1, the lower part of which has a battery 2, a control unit 3, a geo-location beacon 4, the upper part of the housing consists of a solar battery 5 and several lenses 7 for refracting light rays, light sources 6 located inside the housing, for example, in the form of red, green and yellow LEDs.

Battery 2– accumulates the received energy from the solar battery 5 and energizes the control unit 3, the geo-positional beacon 4 and the light sources 6.

The control unit 3 transmits commands from an external control center, or from a traffic light controller, directly to the light sources, for which side this or that light signal should turn on.

Geoposition beacon 4 is intended for transmission to vehicles, over a short distance (not more than 1.5 m), the exact coordinates and the number of the strip on which it is installed. It is a radio transmitter operating at GPS and GLONASS frequencies, and transmitting only the exact coordinates and the number of the strip on which it is located.

The solar battery 5 and lenses 7 are resistant to external influences, in particular to scratches and protected from moisture.

The light source 6 is located at the opposite end of the tube from the lens 7. The light source 6 consists of three components of different colors, red, green and yellow. As an example - LEDs. For each direction, on a command from the center, red lights up on one side, green on the other, or yellow at the same time. The tube is the body of the light source 6, at one end the light source, and ends with the lens 7. In the case of the case 1 having a rectangular shape, partitions (vertically) are installed in it to prevent light scattering to the sides and to strengthen the body 1. The sectional lens 7 is a trapezoid, where the base is the upper and lower part of the light flux tube, and the sides are the outer side of the lens (surface of the roadway) and the inner side is facing the light sources. Lens 7 itself, this is the extreme widest part of a flat-concave scattering lens. The function is to redirect the light flux with a minimum angle from the road surface, thereby obtaining the maximum distance of perception of the light flux.

The device operates as follows. Installed on the surface of the road lane, a controlled differentiated road marker on a traffic light object is switched synchronously with traffic lights, and operates accordingly to permitting signs separately for each lane. Thus, we obtain the differentiation of traffic flow control through the control of lanes.

Consider the option of an intersection with three lanes with traffic lights, and allowed from one road to turn right to the side D (Figure 3). From side A: the rightmost lane is only to the right, the middle lane is only forward, the leftmost is forward and to the left. From B: extreme right only to the right, middle stripe forward and to the right, extreme left only forward. The option when the traffic light is turned on for sides A and B is green, for C and D it is red. The controlled road marker has 4 directions of light signaling, and 3 types of light signals - red, yellow, green.

For an intersection lane with only forward movement, the marker works with a green light. On the other hand, if there are no intersections with minor flows, only the red light signal works.

From the side of A: AD - green.

BD - green (except for the far right lane).

 AU - red.

 BC - green or yellow warning of interference on the right.

From side B: BC - green.

AC - green (except for the far right lane).

VD and AD - red.

From side D: AC and AD - red.

BD - red except for the right edge (from the rightmost strip D to the far right B).

Sun - green.

From side C: AC and AD - red

BD and BC - red.

(figure 3)

Marker management comes from a traffic control center.

Light signals of controlled road markers work simultaneously with traffic lights and with each other.

The red signal works in a blinking mode, where the interval for switching off the light signal “t” is very small, and the glow of red light is “3t” or “4t”.

The yellow signal works in blinking mode, where the shutdown interval is “t”, and the yellow light is “6t” or “8t”.

Green signal in constant light mode.

At intersections of roads without traffic control, markers operate in the green signal mode for the main road and yellow for the secondary, towards the oncoming lane red, at the intersection of special lanes for turning, where it is allowed, but there is interference - yellow, the end of the strip is red.

At roundabouts, in a lane. The right direction is green, the wrong direction is red, the rest is yellow.

At pedestrian crossings, without traffic lights - in the blinking mode in all directions a yellow signal, with a traffic light - respectively a traffic light, by analogy with an intersection.

A controlled differentiated road marker is set along the line of movement (strip), along the central axial line at a distance of 25 cm, if two, and on the center line if one.

The distance between the markers on the track increases according to the allowed speed.

At intersections, they are installed at the intersection of the central axial lines of the strips, or the central axial line with the border of the intersecting strip. At the intersection of the central center lines, 4 markers, or 2, can be set, depending on the priority. In case of narrowing of the road, on the strip that ends, markers are set in two, right yellow, left green, at the end of the strip the last row is red. By the same type, markers are installed at the junction of secondary roads. Right yellow flashing light as a warning of possible interference on the right side.

If the lane is occupied by emergency transport or repair work, controlled road markers in the occupied lane are switched to the yellow signal in advance from the emergency place, and to the red one at the nearest distance.

On roads with reverse traffic, markers are set from the initial intersection to the final, including the intersection area. Green on the allowed side, red on the forbidden side. The other is yellow flashing.

If for a certain time the controlled differentiated road marker does not receive direct sunlight or signals from the control center, the marker goes into standby mode, a yellow flashing signal in all directions. That is, in the case of markers covered with snow or other force majeure situations.

An advantage of the claimed invention is that at complex intersections with many intersecting lanes, it is possible to simplify the recognition of a traffic signal and direction specifically for each lane for drivers. Managed differentiated road markers installed at a certain distance from each other create a visual chain along which you can safely continue driving. In the case of installation on lanes with reverse traffic, it is possible to control traffic flow with switching traffic in any direction, without the risk of emergency situations.

The claimed invention will allow to use the maximum benefit of the entire plane of the roadway, without expanding the road, which is currently a very urgent topic.

In all cities there are many secondary roads, between the main routes, setting multidirectional markers on them and making them reversible, allows you to distribute traffic flows. Prompt “switching” of such roads is the easiest way to redirect vehicles from those routes where traffic is “planned”.

A multi-lane road equipped with controlled differentiated road markers will reduce the bottleneck effect if the lane is occupied by emergency transport or repair work, the markers switch to a yellow flashing signal in advance, which allows drivers to leave the busy lane in advance.

Also controlled differentiated road markers, will duplicate warning signs - light signals. The red and yellow spectrum light signals operating in the blinking mode, directly shining in the eyes, intuitively affect the human consciousness and guide road users along a safe path.

At intersections at night, severe accidents occur, where the drivers become inattentive. Due to the small number of vehicles, the driver relaxes and allows you to increase speed and sometimes does not notice traffic signals, since no one is standing at the intersection, and he can go to the traffic signal barring signal, and the presence of controlled differentiated road markers will increase the driver’s attention to the light signaling.
