Description

Traffic signal system for pedestrian crossings linked with traffic lights {A INFORMATION SYSTEM FOR STREET CROSSING}

The present invention relates to a traffic signal system of a crosswalk associated with a traffic light to operate in conjunction with the intersection traffic light is installed in the crosswalk and installed at the intersection.

In more detail, it is installed before and after the pedestrian crossing (entry and exit) to operate in conjunction with the pedestrian traffic lights and vehicle traffic lights that are usually installed in the pedestrian crossing, but the pedestrian is crossing the crosswalk or at the crosswalk When an approaching vehicle is detected, the situation of the crosswalk (pedestrian crossing the crosswalk or no pedestrian) is indicated by the image of the signboard on the side of the access road entering the crosswalk, and the vehicle traffic light is red. When the pedestrian crosses the crosswalk completely, the traffic lights turn red and at the same time turn the traffic light into green so that the car can cross the crosswalk and when the car crosses the crosswalk, Linked with traffic lights that detect and blink vehicle traffic lights in yellow It is intended to provide a transportation system of pedestrian crossing signals.

In general, crosswalks are installed on roads where vehicles travel to allow pedestrians to cross.

As described above, the pedestrian crossing installed on the road includes a pedestrian traffic light that generates a light signal to allow the pedestrian to recognize whether the crossing is possible, and a driver traffic light that allows the driver to recognize whether the pedestrian crossing is a walking situation. It is provided.

However, conventional pedestrian crossings are equipped only with a signal function that allows the pedestrian and the driver to recognize the situation of the crosswalk, so that the driver cannot accurately grasp the situation of the crosswalk, so that even if the pedestrian enters the crosswalk, In this case, the vehicle stops suddenly at a distance close to the crosswalk and a safety accident occurs.

In addition, since the signal device of the crosswalk that is equipped with only a signal function is a conventional signal device that is automatically turned on periodically even when a pedestrian does not enter the crosswalk, drivers may unknowingly ignore the signal device and drive a safety accident. do.

As a proposal to solve the above conventional problem, a pedestrian protection device of Korean Patent Registration No. 10-982966 has been proposed.

It is equipped with a vehicle detector installed at the side of the road before entering the crosswalk, an alarm at the entrance of the crosswalk of the road, and an alarm equipped with a pedestrian detection unit that detects the pedestrian's motion and an alarm to warn the driver or pedestrian. It is.

In particular, the lighting lamp is a first light that provides different illumination to the driver according to the pedestrian's motion near the crosswalk, and the first light that crosses the crosswalk so that the pedestrian can be identified according to whether the pedestrian crossing the crosswalk. It is designed to prevent accidents by being alerted to vehicles approaching crosswalks in individual situations where pedestrians are crossing with two lights.

However, when the vehicle is detected in the vehicle detection unit installed at the side of the road before entering the crosswalk, the pedestrian detection unit of the alarm installed at the entrance of the crosswalk detects whether there is a pedestrian and turns on the first light. When crossing the pedestrian crossing, the second light is to be turned on.Therefore, there is a limitation of obtaining information that the driver must visually check the pedestrian approaching the pedestrian crossing or crossing the pedestrian crossing. Information on whether or not to cross the street can not be confirmed before approaching the crosswalk and the distance is too short to threaten the safety of pedestrians and can lead to safety accidents.

In particular, the conventional pedestrian traffic lights and warning devices (pedestrian protection devices) are used to be installed at intersections of urban areas where vehicle traffic (traffic) is frequent, and crosswalks on roads with limited vehicle traffic such as surrounding roads and rural roads. There is a limit to the possibility that it is not applicable and used effectively.

The present invention is to provide a traffic signal system of a crosswalk associated with a traffic light, characterized in that it can be operated in conjunction with the intersection traffic light is installed in the crosswalk so as to solve the above problems. .

The present invention is installed in the front and rear (entry and exit) of the crosswalk to operate in conjunction with the pedestrian traffic lights and vehicle traffic lights that are usually installed in the crosswalk, the pedestrian crossing the crosswalk or approach the crosswalk When it is detected, the situation of the crosswalk (pedestrian crossing the crosswalk or no pedestrians) is known by the image using the signboard on the side of the access road that enters the crosswalk, and the traffic light turns on red at the same time. When the pedestrian crosses the crosswalk completely, the pedestrian signal turns red and at the same time turns the traffic light into green so that the car can cross the crosswalk and detects when the car passes the crosswalk and detects it. Blinking yellow and the traffic light and characterized in that the linkage Provide traffic signal system at the crosswalk haryeoneunde has its purpose.

Another object of the present invention is to operate in conjunction with the existing pedestrian traffic lights and vehicle traffic lights installed on the crosswalk, pedestrians do not normally cross the crosswalk, induces the car to cross the crosswalk, pedestrian crossing By operating the existing pedestrian traffic light and vehicle traffic light only when crossing the sidewalk, it is possible to protect the pedestrians and induce the safe driving of cars. I'm trying to provide.

Another object of the present invention, when the pedestrian does not cross the pedestrian crossing, the traffic lights flash green or yellow, usually pay attention when the driver of the vehicle passes the crosswalk, when the pedestrian crosses the crosswalk By displaying the traffic lights in red and visualizing that the pedestrian is crossing the crosswalk by the signboard, pay attention when approaching the crosswalk and stop at the stop line to protect the pedestrian and induce safe driving of the car. The purpose of the present invention is to provide a traffic signal system of a pedestrian crossing associated with traffic lights.

Another object of the present invention is to keep the traffic lights in flashing lights, especially at night from sunset to the next sunrise, so that the car can be guided through the vehicle while recognizing the pedestrian crossing ahead. The purpose of the present invention is to provide a traffic signal system of a crosswalk associated with a traffic light.
