Description

The utility model relates to traffic control devices and can be used to increase the efficiency of traffic control, especially in cases of limited visibility in adverse weather conditions.

A traffic light is known that contains a section with the possibility of forming colored light fluxes, into which a blue source interacting with red and green is introduced into the colored light fluxes to create a flicker effect (US 6707393, G08G 1/095, 2002).

A disadvantage of the known technical solution is the narrow functionality, because, for example, it does not emphasize the geometric shape of the section, which significantly limits its functions.

The prototype is a traffic light containing sections of the main signals placed one below the other with radiation sources of three standard color streams (SU 1377889, G08G 1/095, 1988,02,28).

A disadvantage of the known traffic light is that its technical capabilities do not correspond to the physical abilities of all road users, especially with visual deviations from normal when driving at night, even when there are no factors that limit visibility. Drivers with normal vision determine the traffic light by color. Persons suffering from color deficiency distinguish signals by the location of the included section. In the case of limited visibility, the greatest difficulties in determining the signal are in persons suffering from color deficiency, when it is necessary to see each section of the traffic light. The same difficulties can arise in people with normal vision, since in such conditions twilight vision predominates. A situation is possible when the light signals of a traffic light are difficult to distinguish at all.

The purpose of creating a utility model was to expand the functionality while maintaining the basic cost of the product.

The technical result is achieved by installing part of the elements of the radiation sources of contrasting colors in the section of red and yellow light fluxes, respectively forming a horizontal rectangle and an equilateral triangle against the background of the main color streams, and the green light stream section is equipped with a sound signal source.

The proposed system uses four human response schemes, i.e. within the framework of existing traffic lights, a form and an audio signal are additionally created. Unlike the current 2-position system: color-arrangement, a 4-position signal system is proposed: color-arrangement-form-sound signal.

Description of the improvement: in addition to color and location, additional information regarding the form, i.e. in the red traffic light, a “brick” appears in the same color, but in a contrasting shade; and in the yellow traffic light - a contrast signal of the same color "triangle" or the sign "give way". The green signal can be left unchanged, just a green circle plus a sound signal.

The fundamental difference between the above-described signal system is that it uses not two standard human response schemes (color-location), but four human response schemes (color-location-shape-sound signal), which allows to increase the readability of the signal and, accordingly, the response by at least 50 % The signal perception is facilitated for color blind people, in conditions of poor visibility (fog, smog, etc.), for people with low vision. This extends the functionality of the product.

The new system reads like this: light red horizontal line - the path is closed; light yellow triangle - give way, warning; green circle plus a sound signal - the path is clear, open.

This goal is achieved by the fact that in a traffic light containing sections of the main signals placed one below the other with radiation sources of three standard light fluxes of red, yellow and green colors, according to the claimed utility model, some of the elements of red and yellow radiation sources are made in contrasting colors to display geometric figures of different configurations, and the green light section is provided with a sound signal source. The contrasting color of the elements of the radiation source of the section with the red light flux is made light red to form a horizontal rectangle. The contrasting color of the elements of the radiation source of the section with a yellow luminous flux is made light yellow to form an equilateral triangle.

The utility model is illustrated by the drawing, where in Fig.1 is a traffic light (view from the side of the review) with an example of the formation of geometric shapes.

The traffic light contains sections 1, 2, 3 of the main signals placed one below the other with sources of elemental radiation of red, yellow and green colors representing standard light fluxes.

Some of the elements 4 of the dark red radiation source are made in contrasting light red and depict a horizontal rectangle 5.

Some of the elements 6 of the dark yellow radiation source are made in contrasting light yellow color and depicts an equilateral triangle 7.

Section 3 of the green light flux is provided with an audio signal source 8.

The traffic light works as follows:

When the “forbidden” signal is turned on in the upper section 1, a horizontal rectangle 5 (“brick”) is formed in light red in the background of dark red color.

When you turn on the signal "attention" in the second section 2 against the background of dark yellow is formed an equilateral triangle 7 of light yellow.

When the "enabled" signal is turned on, the green light lights up and at the same time a sound signal sounds.

The utility model will find its application as a device for regulating the movement of traffic flows and pedestrians.

This system can also be effectively used as tags in computer information.
