Description

The invention relates to techniques for regulating traffic and is intended for use in the construction of traffic lights on lines with heavy traffic.

The well-known "ONE-SECTION LED TRAFFIC" RU 2468444 [2], made with the possibility of radiation in a given sequence and at specified intervals of color light fluxes - red, yellow and green in the direction of the approaching vehicle or at pedestrian crossings and consisting of one equipped with sun-rain-snow-protective the visor of the radiating section, the area in the form of a circle, a square on which the sources of radiation of the indicated color light fluxes are installed in the form of two-color red + green LEDs that form when turning on the visible arrows.

The disadvantage of this device is a narrow scope.

The closest technical solution is the “LIGHT TRAFFIC” RU 2 414 753 [1], which includes a housing, an element for attaching the housing to the installation site, with a panel mounted on the housing, an electronic information unit consisting of a signaling device with an indicator of mandatory directions is installed and fixed in the housing traffic, including signs / forward, backward / main road, signs / right, left / secondary road.

A disadvantage of the known traffic light is the low information ability.

The technical result of the invention is to increase the information ability of traffic lights and, as a result, increase road safety.

The technical result is achieved by the fact that the traffic control method is characterized in that the traffic light installed at the intersection at any time with green, yellow and red arrows that are able to change their configuration within a single signal, instructs the driver in which of all possible directions of movement from this approach to the intersection can be (arrow of green color), and in which it is impossible (arrow of red and / or yellow) to move.

Information on the prohibited or permitted direction of movement, intended to be reflected in additional sections, is reflected in the main traffic light sections, which will further increase the concentration of drivers' attention, improve the overall dimensions of the traffic light and increase its reliability by reducing the number of elements, with a non-zero probability of failure.

The traffic light for implementing the traffic control method according to Claim 1, comprises a housing, an element for attaching the housing to the installation site, a control unit installed in the housing, to the output of which three traffic light sections are connected, controls movement only by signals in the form of red, yellow, green arrows , and at each moment of time the set of turned on arrows of red, yellow, green traffic signals shows the traffic pattern of the intersection with this approach to traffic participants.

The implementation of the invention

When considering the issue of improving the design of the traffic light necessary for flexible traffic control, taking into account the achievements of modern technology, arrows of various configurations were chosen as an indication symbol.

The arrow for adjusting the movement is selected as the most understandable and common symbol that does not contradict clause 6.3 of the traffic rules (Traffic signals made in the form of red, yellow and green arrows have the same meaning as round signals of the corresponding color, but their effect only applies to the direction (s) indicated by the arrows.)

The configuration of the arrows was selected according to the purpose of their use and for its perception from the maximum remote distance (at least 100 meters), the height of the arrows is 300 mm. All arrows are shown in the matrix field 31x31 with a step of 10 mm. If necessary, the configuration options of the arrows can be increased. (Fig. 1)

A distinctive feature of the advanced traffic light is the ability

1. At any moment in time, the green and red arrows that are able to change their configuration depending on the situation, show the driver in which of all possible directions of movement, from this approach to the intersection, is possible (green arrow), and in which it is not (red arrow) move,

2. At any moment in time, use the arrows of traffic signals to show the directions in which traffic is allowed (if you see a green signal) or traffic is allowed (if you see a yellow or red signal). Thus, still at the entrance, warning traffic participants about the intersection passage pattern with this approach, and in the absence of appropriate road signs, duplicating them. See FIG. 2, where:

1 - traffic light sections of green color;

2 - traffic light sections of yellow color;

3 - traffic light sections of red color.

4 - corresponding traffic signs.

The proposed mode of operation of the traffic light allows the driver, having taken the required row in advance, to make less rearrangements.

EXAMPLE

At the “T” shaped intersection of FIG. 3, where:

5 - the direction of movement of the driver H2, warned by the declared traffic light;

6 - green signal of the traffic light of the previous modification from the direction H1;

7 - green signal of the traffic light of the proposed model from the direction H1;

8 - red signal of a traffic light of the previous modification from the direction H3;

9 - red signal of the traffic light of the proposed model from the direction of H3;

10 - green signal of a traffic light of the previous modification from the H2 direction;

11 - green signal of the traffic light of the proposed model from the direction of H2.

The driver, seeing the signal of the proposed traffic light when approaching the T-junction from approach H2 (Figure 3), if possible, refrains from taking the left lane, realizing that a car can turn ahead for a U-turn. The traffic signal of the previous modification does not focus the driver's attention on the possibility of such a situation.

There are many similar situations on the roads. The more and more reliable the driver has information, the less there will be accidents and the throughput of the road will increase.

All switching from green to red and from red to green are carried out according to the usual driver scheme, through a yellow signal (as provided by GOST 52289-2004). An example is shown in FIG. 4.

If during the transition from one phase of movement to another there is a partial change (of one of two or two of three) green arrows to red, then in preparation for switching only those green arrows (one of two or two of three) that in the next phase of movement flash switch to red. See H1, H2 (F1) FIG. 5.

It should be especially noted that when using the traffic light of the proposed model with variable information of signals, for the separate regulation of traffic in the lanes (H1, H2 Fig. 5,), the use of additional sections is not required.

Comparison Options for Equivalent Traffic Signals of Traditional and Advanced Traffic Lights See FIG. 6, where the old, traditional modifications of traffic lights with additional sections are shown in the left vertical rows, and the proposed traffic light without additional sections in the right vertical rows.

The traffic signals of the proposed modification accurately indicate all the allowed and currently prohibited directions of traffic from this approach to the intersection.

As a result of the improvement of the traditional traffic light, two modifications appeared:

On. FIG. 7 to 11 versions of the traffic light of constant information;

In FIG. 8 - traffic light of variable information, in the three signal fields of which, replacing each other, any variants of signal symbols are displayed (Figure 1), which, according to the controller’s commands, can be switched on in red, yellow or green traffic signals in a certain sequence.

As a result of the above, it can be noted that the essential novelty of advanced traffic lights is the ability:

control movement only with signals in the form of arrows of red, yellow and green colors;

change the configuration of the arrows in the field of red, yellow or green signal, which is necessary when separately controlling the movement in lanes without additional sections from one of the approaches to the intersection;

absolutely precisely at any moment of time, by the totality of the included red, yellow and green traffic light arrows, inform traffic participants about the intersection passage pattern from this approach.

EFFECT: increased information ability is achieved by the fact that a traffic participant receives complete information about all possible options for the direction of traffic both when driving to a traffic light allowing signal, and in standby mode when a traffic light is forbidden, which will increase the awareness of a traffic participant, and will allow road users to be prepared and in advance to take the right actions when rebuilding, thereby improving road safety.

The claimed traffic light allows you to:

inform, at any moment of time, by signals in the form of arrows, road users about the intersection passage pattern by means of a combination of red, yellow and green traffic signals;

change the configuration of the arrows in the field of one signal, which is necessary for separate control of the movement in lanes without additional sections from one of the approaches to the intersection.

Industrial applicability. The claimed design and technical solution can be successfully used for the manufacture of traffic lights with high information ability.
