Abstract

The present invention relates to a road-embedded traffic signal that can be installed on a road used by vehicles to provide safety and convenience to drivers. The present invention provides a road-embedded traffic signal that improves driving convenience and safety by implementing a new type of traffic signal that provides traffic signal information to drivers by embedding a signal light linked to an existing signal system on one side of a road used by vehicles, for example, on a road lane adjacent to a vehicle stop line at an intersection, thereby enabling signal confirmation even in situations where forward visibility is obstructed, such as when the signal light is not visible, and providing accurate signal system information. Furthermore, it promotes safe driving and prevents traffic accidents by linking the traffic light embedded in the road with the weather system of the Korea Meteorological Administration and installing heating cables on the road around the signal light to prevent traffic accidents during inclement weather.

In claim 1, A road-embedded traffic signal, characterized by including a receiver (16) installed on one side of the above-mentioned traffic light (11) and electrically connected to the PCB (12) side to receive weather information from the weather system (15) of the meteorological agency, and a heating wire (17) installed parallel to both sides of the width of the above-mentioned traffic light (11) and capable of generating heat, and capable of melting snow accumulated on the road surface around the traffic light through the heating function of the heating wire (17) according to the snow forecast received from the weather system (15).
In claim 1, A road-embedded traffic signal, characterized by including a receiver (16) installed on one side of the traffic signal (11) and electrically connected to the PCB (12) side to receive weather information from a weather system (15) of a meteorological agency, and a heating wire (17) capable of generating heat installed parallel to both sides of the width of the traffic signal (11), a method of operating the heating wire (17) by using a step of setting a temperature for operating the heating wire (17), and a step of comparing the current temperature of the area where the traffic signal (11) is installed with the set temperature, turning the heating wire (17) OFF when the current temperature exceeds the set temperature, and supplying power to the heating wire (17) to turn the heating wire (17) ON when the current temperature is less than the set temperature.
In claim 1, The above traffic light (11) is a road-embedded traffic light characterized by being able to adjust the amount of light brightness during daytime and nighttime.
In claim 1, The above traffic light (11) is a road-embedded traffic light characterized by operating in a manner that flashes on and off until the traffic signal is switched according to the remaining time of the current traffic signal.

Description

Embedded traffic light The present invention relates to a road-embedded traffic signal, and more specifically, to a road-embedded traffic signal that is installed on a road where vehicles travel and can provide safety and convenience to drivers. Generally, traffic lights are installed on roads where vehicles travel to control the flow of vehicles, and through these traffic lights, stop and go signals are alternately turned on and off according to traffic conditions, thereby encouraging safe driving of vehicles. Traffic lights designed to control the flow of vehicles are positioned in the air above intersections or crosswalks so that drivers can easily see them, and are installed in a structure supported by a traffic light installation structure consisting of vertical posts and horizontal support beams. Traffic lights, designed to ensure safe traffic order on roads where vehicles typically operate, are configured to form a single lighting unit by combining basic signals such as red (Red, R), yellow (Yellow, Y), green (Green, G), and arrow (A), and lighting control is performed to suit the road environment through a traffic signal controller installed near the signal light. However, existing traffic lights have the following disadvantages. 1) When a vehicle is stopped behind a large vehicle, such as a bus or truck, to wait for a signal at an intersection, it is often difficult to see the traffic light ahead, making it difficult to check the signal. 2) There is difficulty in distinguishing signals due to the increasingly complex signaling systems of traffic lights. 3) It is difficult to check the signal when stopping past the stop line or before the stop line. 4) It is difficult to check the lane in rainy weather and difficult to stop at the stop line in heavy snow. 5) Drivers have difficulty recognizing traffic lights due to backlighting at sunrise or sunset. 6) Since the stop line is a point where it is difficult to recognize traffic lights, drivers may fail to recognize the signal and cause pedestrian accidents. 7) Since a traffic light of one color is lit for a set period of time and then suddenly changes to a different color when the time is up, drivers cannot know when the green light, which is the signal to proceed, will change. As a result, when the signal changes suddenly, drivers often become flustered and suffer unexpected accidents. 8) When vehicles pass through an intersection while the green light is on, they cannot check when the yellow and red lights will turn on, and this can lead to tailgating or sudden braking, which may result in a rear-end collision. FIGS. 1 and FIGS. 2 are perspective views showing a road-embedded traffic signal light according to an embodiment of the present invention. FIG. 3 is a cross-sectional view and a plan view showing the installation state of a heating wire in a road-embedded traffic signal light according to an embodiment of the present invention. FIG. 4 is a flowchart showing the operating state of a heating element in a road-embedded traffic signal light according to an embodiment of the present invention. FIG. 5 is a plan view showing the usage state of a road-embedded traffic signal light according to an embodiment of the present invention. The present invention will be described in detail below with reference to the attached drawings. FIGS. 1 and FIGS. 2 are perspective views showing a road-embedded traffic signal light according to one embodiment of the present invention, and FIG. 3 is a cross-sectional view and a plan view showing the installation state of a heating wire in a road-embedded traffic signal light according to one embodiment of the present invention. As illustrated in FIGS. 1 to 3, the road embedded traffic signal is installed on the road surface and allows the driver to check the current traffic signal in situations where the forward view is obstructed by buses, trucks, etc., thereby providing safety and convenience to the driver. To this end, the above-mentioned road embedded traffic signal includes a signal light (11) that is embedded in the road surface, and this signal light (11) is linked with a normal general traffic signal light (reference numeral 21 of FIG. 5) installed in the air above the road and turns on and off as a red, green, or yellow light to instruct passing vehicles to stop or proceed, that is, it performs the function of a traffic signal light that provides information about the current traffic signal, such as stopping or proceeding, to the driver of a passing vehicle. For example, when the red light of the general traffic signal (21) is turned on, the red light of the signal light (11) embedded in the road surface is turned on, and when the green light of the general traffic signal (21) is turned on, the green light of the signal light (11) embedded in the road surface is turned on, and when the yellow light of the general traffic signal (21) is turned on, the yellow light of the signal light (11) embedded in the road su
