Description

Pedestrian traffic light to prevent pedestrian accidents caused by vehicles turning right}

The present invention relates to a traffic light installed for pedestrians crossing a crosswalk. In more detail, the driver of a vehicle turning right at a crosswalk indirectly checks the signal status of the pedestrian traffic light, thereby protecting pedestrians on the crosswalk and safely. This is about a pedestrian traffic light that prevents pedestrian accidents by allowing right turns.

In general, it is known that approximately one in two traffic accidents occur at or near intersections and are often caused by unreasonable signal systems.

In particular, traffic accidents between pedestrians and vehicles frequently occur at crosswalks installed around intersections as right-turning vehicles are allowed to pass.

In the current traffic signal system, right-turning vehicles must stop at a red light, and if there are no pedestrians on the crosswalk, they can turn right while driving slowly so as not to disturb other vehicles.

However, currently, pedestrian traffic lights generally installed at crosswalks have red and green lamps arranged up and down toward the front to facilitate pedestrian identification, and the red and green lamps are each covered with a shade to block rainwater. Therefore, there is a problem that it is difficult for the driver of a right-turning vehicle to recognize the pedestrian signal in advance.

In particular, since right turns are made in the rightmost lane, there is a problem in that it is difficult to check the status of the pedestrian traffic light on the opposite side when a large bus or truck is waiting at the signal in the left turn lane and straight lane.

In the end, the driver of a right-turning vehicle checks the walk signal and makes an abrupt stop only when he approaches the crosswalk very close or when a pedestrian begins to cross the crosswalk, and this process often leads to traffic accidents. .

First, the pedestrian traffic light for preventing pedestrian accidents caused by right-turning vehicles according to an embodiment of the present invention is largely installed on a sidewalk with a crosswalk and includes a traffic light body that operates red and green lights for pedestrians, and a traffic light body. It is divided into a control unit that operates the red and green lights, and a beam generator that is linked to the operation of the red and green lights and emits an indicator beam to the floor around the crosswalk so that the driver of the right-turning vehicle can determine the operation status of the traffic light. It can be, and each configuration will be looked at in more detail with reference to the illustrated drawings below.

First, the traffic light body 100 is,

It is installed on a sidewalk where a crosswalk is installed, and is installed to face each other around the crosswalk, and is installed by hanging on the prop 200 while a prop 200 is installed on the sidewalk.

The traffic light body 100 is equipped with a red light 110 that emits red light through a light emitting means such as an AD module and a green light 120 that emits green light on the upper and lower sides of the front, and the traffic light body ( On the front of 100), a visor 102 is provided to prevent surface contamination of the red light 110 and green light 120 and to enable pedestrians to accurately recognize the operation of the red light 110 and green light 120 during the day. are installed above the red light 110 and above the green light 120, respectively.

The red light 110 and green light 120 of the traffic light body 100 receive signals from the traffic signal controller and are operated alternately through the control unit, and the operating status of the green light 120 and red light 110 is monitored by pedestrians. After checking, you can safely cross the road using the crosswalk.

A beam generator is provided inside the traffic light body 100, and the beam generator can be in the form of a beam projector, which is equipment that projects a slide or video onto a screen using light passing through a lens.

Here, a beam projector using a cathode ray tube (CRT) method, a liquid crystal display (LCD) method, a digital light processing (DLP) method, or a liquid crystal on silicon (LCos) method may be used.

The present invention is designed to generate a right turn prohibition indicator beam 140 and a right turn possible indicator beam 150, which indicate a right turn prohibited state or a right turn possible state of a right turning vehicle, through this beam generator, and this right turn prohibited indicator beam 140 ) and the right turn possible indicator beam 150 can be illuminated to the outside of the traffic light body 100.

Accordingly, a beam passing hole 130 of a predetermined size is formed on the side of the traffic light body 100, and a right turn prohibition indicator beam 140 or a right turn generated from the beam generator installed inside the traffic light body 100 is formed. The possible display beam 150 may pass through the beam passage hole 130 and be irradiated to the outside of the traffic light body 100.

The right turn prohibition indicator beam 140 or the right turn possible indicator beam 150 projected to the outside of the traffic light body 100 is illuminated downward on the floor around the crosswalk, and the right turn prohibition indicator beam 140 or the right turn possible indicator beam ( 150) It is desirable that the floor surface to be irradiated is configured to be irradiated between the crosswalk and the temporary stop line on the side where the right-turning vehicle approaches so that the driver of the right-turning vehicle can check before entering the crosswalk.

Here, when the beam passing hole 130 is formed on the side of the traffic light body, the installation angle of the beam generator located inside is adjusted to create a right turn prohibition indicator beam 140 or a right turn possible indicator passing through the beam passing hole 130. The beam 150 can be illuminated on the floor between the temporary stop line and the crosswalk, which is clearly visible to the driver of a right-turning vehicle. An inclined protrusion is formed on the side of the traffic light body, and the beam is beamed through this protrusion. When the through hole 130 is formed, the right turn prohibition indicator beam 140 or the right turn possible indicator beam 150 passing through the beam through hole 130 is clearly visible in the driver's field of view of the right turning vehicle between the temporary stop line and the crosswalk. The bottom surface can be surveyed more accurately.

Meanwhile, the beam generator is connected to and controlled by a control unit that operates the red light 110 and green light 120 of the traffic light main body 100, and the green light 120 of the traffic light main body 100 is operated by the control unit. In this case, the right turn prohibition indicator beam 140 may be radiated from the beam generator to the outside of the traffic light body 100 and onto the floor before the crosswalk on the side where the right-turning vehicle approaches, and the traffic light body 100 may be illuminated by the control unit. ) When the red light 110 is activated, the right turn possible indicator beam 150 is projected from the beam generator to the outside of the traffic light body 100 and can be illuminated on the floor before the crosswalk on the side where the right turn vehicle approaches. there is.

The right turn prohibition indicator beam 140 or the right turn possible indicator beam 150 emitted from such a beam generator may be configured in various forms without having to be determined by any one form, and may be displayed as letters or symbols. For example, in the case of the no right turn indicator beam 140, the letter " It may be configured in an overlapping form.

In addition, the right turn prohibition display beam 140 or the right turn possible display beam 150 may be expressed in black and white or color. Preferably, the right turn prohibition display beam 140 is configured in red, and the right turn possible display beam 150 is It may also consist of green.

On the other hand, external foreign substances such as dust or rainwater can easily enter the beam passage hole 130 formed in the traffic light body 100, and if it enters, the traffic light may malfunction due to failure of internal components, etc. Since a failure may occur, it is preferable that a transparent lens is installed in the beam passing hole 130, for example.

As another example, a magnifying lens may be installed in the beam passing hole 130. In this way, when the magnifying lens is installed in the beam passing hole 130, the inflow of foreign substances such as dust or rainwater through the beam passing hole 130 is prevented. At the same time, the right turn prohibition indicator beam 140 or the right turn possible indicator beam 150 generated from the beam generator is magnified by the magnifying lens and illuminated on the floor before the crosswalk on the side where the right turn vehicle approaches. Accordingly, the driver of a right-turning vehicle can more accurately and quickly recognize the right-turn prohibition indicator beam 140 or the right-turn possible indicator beam 150.

Meanwhile, the driver of a vehicle making a right turn can easily check the side of the traffic light body 100 installed at the crosswalk, so there is a right turn prohibition light 160 that lights in red on the side of the traffic light body 100 and a right turn light that lights in green. Each indicator light 170 is installed, and when the right turn prohibition indicator light 160 and the right turn possible indicator light 170 are controlled by the control unit, the green light 120 located in the front of the traffic light body 100 is activated. The red right turn prohibition indicator light 160 located on the side of the traffic light body 100 operates together, and when the red light 110 located in the front of the traffic light body 100 is activated, the red right turn indicator light 160 located on the side of the traffic light body 100 operates. By configuring the green right turn possible indicator light 170 to operate together, the driver can see the right turn prohibited indicator beam 140 or the right turn possible indicator beam 150 illuminated on the floor around the crosswalk and the side of the traffic light body 100. After determining whether the right turn prohibition light 160 or the right turn possible light 170 is activated, a right turn is made, thereby effectively preventing accidents with pedestrians using the crosswalk.

In addition, in some cases, the driver of a vehicle turning right may use a right turn prohibition indicator beam 140 or a right turn possible indicator beam 150 illuminated on the floor around the crosswalk, and a right turn prohibition indicator light operated on the side of the traffic light body 100. By approaching a crosswalk where the green light 120 of the traffic light body 100 is activated without checking both the (160) and the right turn indicator light (170), pedestrians using the crosswalk may be exposed to danger. .

Therefore, the speaker 180 is installed on either surface of the traffic light body 100, and when the green light 120 of the traffic light body 100 is turned on through the control unit, the control unit uses the speaker 180 to By having a voice informing that entry is prohibited be transmitted to the outside of the traffic light body 100, the driver of a vehicle trying to turn right can use the right turn prohibition indicator beam 140 illuminated on the floor around the crosswalk or the side of the traffic light body 100. If you continue to enter the crosswalk without checking the right turn prohibition light (160) that is activated, you will hear a voice informing you that right turn vehicles are prohibited from entering through the speaker (180) and will be able to stop, so pedestrians using the crosswalk will be able to stop. It is possible to effectively prevent accidents.

Here, the point at which a voice informing that entry of right-turning vehicles is prohibited is transmitted through the speaker 180 is when a sensor connected to the control unit is placed on the side of the traffic light body 100, and a green light ( When a right-turning vehicle approaches within a certain range of the crosswalk while 120) is activated, it is desirable to repeatedly transmit a voice through the speaker 180 informing that the right-turning vehicle is prohibited from entering once or several times.

Meanwhile, in another embodiment of the present invention, various shapes of signs indicating that right turns are prohibited or right turns are possible are displayed on the visor 102 of the traffic light body 100 using lighting means such as LEDs or means such as reflective sheets, so that right turning vehicles Drivers can also check whether right turns are prohibited or possible.

That is, for example, as shown in (a) of FIG. 4, there is a right turn possible auxiliary light 192 and a right turn prohibited auxiliary light 191 on the side of the visor 102, which have a shape corresponding to the overall shape of the side of the visor 102. Each may be installed, and a circular right-turning auxiliary light 192 and a right-turning prohibited auxiliary light 191 may be installed on the side of the visor 102, as shown in (b) of FIG. 4, respectively, and (c) of FIG. 4 ), a right turn arrow-shaped right turn enabled auxiliary light 192 and an A right turn enabled auxiliary light 192 and a right turn prohibited auxiliary light 191 each having a shape corresponding to the partial shape of the side of the visor 102 may be installed on the side of the visor 102).

In addition, as shown in (e) of FIG. 4, the shape of the visor 102 deviates from the existing triangular shape and is composed of a square, etc., and the visor 102 is equipped with a circular right-turn auxiliary light 192 and a right-turn prohibition auxiliary light. Lights 191 may be installed respectively.

Here, the above-mentioned right turn possible auxiliary light 192 and right turn prohibited auxiliary light 191 are also under the control of the control unit, and when the red light 110 of the traffic light body 100 is activated, the right turn possible auxiliary light 192 is connected to this. is activated, and conversely, when the green light 120 is activated, the right turn prohibition auxiliary light 191 may be activated in connection with this.
