Description

Complex traffic light system {A complex traffic light}

The present invention relates to a traffic light device for a pedestrian crossing, more specifically, to a composite traffic light device that has a design that enhances aesthetic sense, can provide a variety of information, and can improve pedestrian safety.

As is well known, as of 2012, the number of deaths per 100,000 people walking in Korea was 4.1, four times higher than the OECD average of 1.1. In particular, 4 out of 10 deaths in traffic accidents are pedestrians, and the fatality rate of pedestrian accidents is twice as high as that of all traffic accidents. Therefore, measures for pedestrian accidents were desperately needed.

On the other hand, a traffic safety facility means a sign indicating a caution, regulation, or instruction necessary for traffic safety, or a sign, text, or line displayed on the floor of a road. In addition, the road safety facility is a facility installed to increase the safety of the road and protect the driver. It refers to a protective fence, a median, and a shock absorbing facility. In addition, road linear design refers to the task of designing the geometric conditions of the road in advance and designing the mechanical and spatial relationship with the driving vehicle in a safe condition in terms of road facilities.

The upgraded recent technology of the above-mentioned conventional facility is as follows.

In other words, in pedestrian crossings in some areas, infrared sensors are used at the borders of crossings to provide warnings and announcements when pedestrians approach by car. In addition, on roads with wide lanes (e.g., 8 lanes), for the safe crossing of pedestrians, the remaining time is displayed on traffic lights to induce safe crossing. In addition, in order to protect pedestrians at night, some areas are taking measures to increase pedestrian awareness from drivers by lighting crosswalks with lights.

In some cases, the auxiliary speaker 141 may be installed at a location spaced from the traffic light. FIG. 5 exemplifies emitting a warning sound guiding a ban on crossing while waiting for a crosswalk, and FIG. 6 illustrates that a pedestrian traffic light turns from red to green to emit a guide sound for guiding pedestrian crossing. have.

Meanwhile, as illustrated in FIGS. 7 and 8, at a predetermined height inside the vertical pillar member 100, a traffic light post 110c and a set of walking traffic lights 110: 110a and 110b are accommodated. The traffic light post 110c is shaped, for example, in a cylindrical shape, and the case of the walking traffic light 110: 110a, 110b is formed to contact the outer surface of the traffic light post 110c. The case of the pedestrian traffic lights (110: 110a, 110b) is fastened by a fastening means at the contact portion and is coupled to the traffic light post (110c). Each walking traffic light case is formed in a shape that one side is in contact with each other, it is possible to improve the coupling force between the traffic light pole (110c) and the walking traffic light (110a, 110b).

The inclined pillar member 200 is formed to be inclined at a predetermined angle from the top of the vertical pillar member 100. The second lamp 220 is formed on the inclined pillar member 200. The second light 220 illuminates the driver's attention on the pedestrian crossing and illuminates the pedestrian's road crossing when the pedestrian traffic light turns green. The second illumination lamp 220 is mainly intended to alert the driver of the vehicle, and is preferably irradiated with white light or red light. 5 illustrates white light and FIG. 10 illustrates red light.

The horizontal pillar member 300 is formed to extend in the horizontal direction from the end of the inclined pillar member 200. A traffic light 310 for the vehicle and a second display 320 are formed on a side surface of the horizontal pillar member 300 (a surface facing the driving vehicle). The second display 320 may transmit useful information to the vehicle driver. A third lighting lamp (see FIGS. 9 and 330) is formed on a lower surface (a surface facing the road surface) of the horizontal pillar member 300. As shown in FIG. 11, the third lighting lamp 330 irradiates red light toward the stop line of the road to call attention of the vehicle driver. The third lighting lamp 330 may be irradiated in the form of a letter pattern of “observing the stop line”.

As described above, the composite traffic light according to the embodiment of the present invention has a design for improving aesthetic sense, can provide various information, and can improve pedestrian safety.

Next, a composite traffic light device according to a second embodiment of the present invention will be described with reference to FIGS. 12 and 13. 12 is a perspective view showing that the composite traffic light device according to the second embodiment of the present invention is installed on the side of a road where a pedestrian crossing is formed, and FIG. 13 is a composite traffic light device according to the second embodiment of the present invention. Side view.

12 and 13, the composite traffic light device according to the second embodiment of the present invention includes a vertical pillar member 100, an inclined pillar member 200, and a horizontal pillar member 300. . The vertical pillar member 100, the inclined pillar member 200, and the horizontal pillar member 300 are substantially the same as the first embodiment described above.

However, in the second embodiment, the vertical pillar member 100 further includes a sensor unit 150 and a blocking bar 160, and a control unit (not shown) speeds the vehicle sensed by the sensor unit 150. And calculates the distance, and when the calculated vehicle distance-to-vehicle speed is greater than a predetermined reference value, the warning bar is emitted through the speaker 140 and the blocking bar 160 is controlled to descend. The preset reference value can be set using empirical, experimental, and statistical data.

The sensor unit 150 detects a vehicle driving on the road. The sensor unit 150 mainly detects a driving vehicle at a time when the pedestrian traffic light is switched from red to green.

The sensed sensing information is transmitted to the control unit, and the control unit uses the sensing information to calculate the speed of the vehicle approaching the traffic light and the distance between the traffic light and the vehicle. The sensor unit 150 may use various sensors, such as a laser sensor and an ultrasonic sensor. For example, the sensor unit 150 emits a laser, and changes the time and intensity, frequency, and polarization state of the returned or scattered laser. It may be a LiDAR (Light Detection And Ranging) sensor that measures the distance and speed of a measurement object from changes.

When the pedestrian traffic light 110 is changed from red to green, the vehicle compares the calculated distance and speed of the vehicle with a preset reference value, and if the calculated vehicle distance and speed is greater than the preset reference value, the corresponding vehicle is a pedestrian traffic light. Even if it turns green, it is likely to pass without stopping. Accordingly, the controller provides an audible signal such as a warning sound to the pedestrian through the speaker 140 to call attention to the pedestrian crossing approaching vehicle. In addition, the control unit controls the blocking bar 160 to go down, thereby providing a visual signal to the pedestrian to temporarily stop the pedestrian's pedestrian crossing to reduce the risk of an accident.

On the other hand, the control unit may control the signal switching of the pedestrian traffic light 110 to reduce the risk of an accident.

When the pedestrian traffic light 110 is switched from red to green, the vehicle's distance-to-vehicle speed is greater than a preset reference value and the vehicle's distance-to-vehicle speed is greater than the preset reference value. By delaying the signal, an accident can be prevented by a vehicle driving while ignoring the signal. At this time, only the signal switching of the pedestrian traffic light 110 is delayed, and the signal switching of the vehicle traffic light 310 can be performed as it is.

The control of the signal switching of the walking traffic light 110 of the control unit may be performed together with the emission of a warning sound or the lowering of a blocking bar, or may be performed separately from these.

Next, a composite traffic light device according to a third embodiment of the present invention will be described with reference to FIGS. 14 and 15. 14 and 15 are perspective views showing a composite traffic light device according to a third embodiment of the present invention.

14 and 15, the composite traffic light device according to the third embodiment of the present invention, the vertical pillar member 100, the inclined pillar member 200, the horizontal pillar member 300, and walking It includes a signal lighting member 400. The vertical pillar member 100, the inclined pillar member 200, and the horizontal pillar member 300 are substantially the same as the first and second embodiments described above. However, in the third embodiment, the walking signal lighting member 400 is further included.

The walking signal lighting member 400 is a lighting bar 410 extending in a horizontal direction parallel to the road surface from the side of any one of the vertical pillar member 100, the inclined pillar member 200, and the horizontal pillar member 300. ) And the floor lighting 420 irradiating red or green light from the lower surface of the lighting bar 410 toward the floor of the side of the sidewalk.

The floor lighting 420 is synchronized with the pedestrian traffic light 110 to irradiate green light toward the floor of the side of the sidewalk when the pedestrian traffic light 110 is green (see FIG. 14), and the floor of the sidewalk when the pedestrian traffic light 110 is red. By irradiating red light in the direction (see FIG. 15), the current signal state can be checked through the floor.

The control unit controls the walking traffic light 110, the vehicle traffic light 310, and the floor light 420, and the walking traffic light 110 and the floor light 420 are synchronized to switch signals.

When the pedestrian traffic light 110 is switched from red to green, the vehicle's distance-to-vehicle speed is greater than a preset reference value and the vehicle's distance-to-vehicle speed is greater than a preset reference value. By delaying the 420) from turning green, an accident can be prevented by a vehicle driving while ignoring the signal. At this time, only the signal switching of the pedestrian traffic light 110 and the floor light 420 may be delayed, and the signal switching of the vehicle traffic light 310 may be performed as it is.

Current floor traffic lights simply turn red/green in connection with pedestrian traffic lights to display traffic light information, and do not reflect information about vehicles approaching pedestrian crossings. Therefore, when a smokin walking with a smartphone checks a green signal through a floor traffic light and walks immediately, it is very likely that a traffic accident is caused by a vehicle approaching a pedestrian crossing at a high speed.

However, in the case of the pedestrian traffic light 110 and the floor light 420 according to the present embodiment, when there is a vehicle approaching the pedestrian crossing at a high speed, the vehicle traveling by ignoring the signal by delaying the signal from turning green. This can prevent an accident from occurring. In addition, since the floor light 420 is not embedded in the ground, there is an advantage that installation is simple and installation cost can be reduced.

The embodiments of the present invention have been described above, but those skilled in the art can add, change, delete, or add components within the scope of the present invention as set forth in the claims. It will be said that the present invention can be variously modified and changed by the like, and this is also included within the scope of the present invention.
