Description

Road traffic signal control system

The present invention relates to a road traffic signal control system in the field of traffic technology, and more specifically, an LED traffic sign is installed in front of a pedestrian crossing to indicate a sign when a pedestrian passes, causing an alert to vehicle drivers and causing an accident in a pedestrian crossing. It relates to an improved road traffic signal control system to prevent the future.

In general, the road is composed of a roadway 10, a sidewalk 20, and a pedestrian crossing 30, as shown in FIG. 1, and a vehicle traffic light 40 and a pedestrian traffic light 50 are installed to be controlled by the signal controller 60. Make up.

However, in the general road, the vehicle determines that there is no pedestrian even if the signal of the pedestrian crossing 30 turns to green, so it runs through at high speed and causes human injury. At night, the driver's grasp of the pedestrian crossing 30 is late, and more A pedestrian crossing accident is occurring.

In addition, when the road is contaminated, there is no system to periodically clean it, which wastes manpower, time, and money.

According to the present invention, it is possible to obtain an improved effect to prevent the accident of a pedestrian crossing in advance by installing an LED traffic sign in front of the pedestrian crossing to display a sign when a pedestrian passes, thereby raising awareness to the vehicle drivers.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

2 and 3, the road traffic signal control system according to the present invention includes a signal processing unit 500.

The signal processing unit 500 includes a traffic controller 550 for controlling traffic signals 510, pedestrian traffic lights 520 and LED traffic signs 540, and a detector 530 capable of detecting pedestrian traffic. do.

The signal processing unit 500 is installed on the roadway 100, the sidewalk 200, and the pedestrian crossing 300 so that the signal of the detector 530 is transmitted to the signal controller 550 when the pedestrian crossing 300 waits. When the pedestrian traffic light 520 is a red light, the LED traffic sign 540 indicates a pedestrian waiting, and when the pedestrian traffic light 520 is a green light, the LED traffic sign 540 is displayed as a pedestrian crossing. When the atmosphere is not detected by the detector 530, the LED traffic sign 540 is marked with a front pedestrian crossing to make vehicle drivers more safe, thereby preventing pedestrian crossing accidents as much as possible.

That is, according to the present invention, a detector 530 is installed to detect when 15 kg or more of each of the crosswalks 300 operate at the start and end points of the crosswalk 300, and this is displayed on the LED traffic sign 540 through the signal controller 550. By making it possible to cause the vehicle driver to be alert to the pedestrian crossing 300, to prevent the accident of the pedestrian crossing 300.

In addition, in the present invention, the signal processing unit 500 further enhances visibility while inducing the driver's awareness and induces safe driving. In particular, a warning beam is fired to further secure pedestrian safety at night crossing a pedestrian crossing. It is configured to be.

For example, as illustrated in FIG. 4, a warning beam emitter 560 is buried over a vehicle width 50 m in front of the pedestrian crossing 300.

The warning beam emitter 560 includes a plurality of triangular prisms 562 installed in an interior space excavated in the vehicle width direction, an LED 564 irradiating red light toward the triangular prism 562, and the triangular prism ( It includes a transparent reinforced plastic 566 that secures the light so that light can be transmitted while protecting the top surface of the 562).

At this time, the triangular prism 562 has a structure in which a mirror surface M is formed by depositing opposing surfaces of aluminum so that light reflection is smoothly performed.

In addition, the LED 564 is configured to be operated at the same time as the pedestrian traffic light 520 is turned on.

Therefore, when the pedestrian traffic light 520 is turned on, a strong red light column, that is, a warning beam, rises from the front of the 50m.

Because of this, the driver is tensed with a red light column, naturally reducing the speed of the car, and this will not only induce low-speed passage when passing through the pedestrian crossing 300, but also ensure more safety due to alertness and long-lasting feeling.

In addition, a plurality of cleaning nozzles 310 may be further installed at the center of the vehicle width.

The cleaning nozzle 310 is configured to be able to appear upward and downward from the floor surface of the driveway, as illustrated in FIGS. 5 and 6.

At this time, a cleaning water pipe 320 is buried in the bottom surface.

In addition, the electric communication pipe 330 in which electric wires and communication wires are wired toward the cleaning water pipe 320 is buried, and a nozzle base 340 is fitted at the top of the electric communication pipe 330, and the nozzle base 340 At the center of the circle, a discharge assembly 350 having a predetermined radius and opening and closing the cleaning nozzle 310 is installed.

In this case, if necessary, an induction lamp (LED) may be further installed in the circumferential direction of the cleaning nozzle 310. In this case, the induction light (LED) can also act as a kind of central lane.

Meanwhile, the discharge assembly 350 is integrally formed with the tubular body 352, the working rod 356 embedded in the tubular body 352 and having a through hole 354 in the center, and the working rod 356. It is fixed and has a smaller diameter than the working rod 356 and the inside of the rod is emptied, and the rod inserting pipe 358 is screwed to the upper outer circumferential surface of the tubular body 352 while supporting it through. A cap 360 that restricts the movement of the working rod 356, a lower hanger opening 362 that is fastened to the lower end of the tubular body 352, and a fastened fastened to the upper end of the rod inserting tube 358 It includes a compression spring (366) that acts to connect the upper hook (364), the lower hook (362) and the upper hook (364) so that the rod insertion tube (358) is always pulled.

In addition, the above-described cleaning nozzle 310 is fixed to the top of the rod insertion tube 358.

Thus, when the cleaning water is not supplied, because the water pressure does not act, the working rod 356 is lowered to the bottom dead center by the pulling force of the compression spring 366, so that the cleaning nozzle 310 is in close contact with the center of the circle. maintain.

Then, when the cleaning water is supplied for cleaning, as the water pressure increases, the compression force of the compression spring 366 is overcome, and as a result, when the operating rod 356 rises and then rises to the maximum dead center, the cleaning nozzle 310 is exposed to the upper part. The cleaning water is sprayed through the discharge hole TR to clean the road.
