Description

A complex traffic light device

The present invention relates to a traffic light device for crosswalks, and more specifically, to a complex traffic light device that has a design that improves aesthetics, can provide various information, and improve the safety of pedestrians.

As is well known, the number of walking deaths per 100,000 in Korea in 2012 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 that of all traffic accidents. Therefore, measures against pedestrian accidents were urgently needed.

On the other hand, traffic safety facilities refer to signs indicating cautions, regulations, instructions, etc. necessary for traffic safety, or signs, characters or lines displayed on the floor of a road. In addition, road safety facilities are facilities installed to increase road safety and protect drivers, and refer to protective fences, median separators, and shock absorption facilities. In addition, road linear design refers to designing the geometrical conditions of the road in advance and designing the mechanical and spatial relationships with the driving vehicle as safe conditions in terms of road facilities.

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

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

The front pedestrian traffic light 110a provides traffic light information to pedestrians waiting on the sidewalk, and the side pedestrian traffic light 110b provides not only the pedestrian walking on the sidewalk, but also the driver of the vehicle, especially the driver of a right-turning vehicle. Is provided so that you can check the traffic light information of,

A first lighting lamp 120 is formed on the other side of the vertical column member 100. The first lighting 120 may visually call attention to pedestrians by providing green lighting to pedestrians waiting on the sidewalk by assisting the pedestrian traffic lights 110b when the pedestrian traffic lights change from red to green. In particular, the walking signal auxiliary function by the first lighting lamp 120 is a smombie (smart phone) and a zombie walking while looking at a smartphone without staring at the walking traffic light 110a in the front. It is possible to provide useful walking signal information to It is preferable that the blinking period of the first lighting lamp 120 is synchronized with the red/green switching period of the pedestrian traffic lamp.

Meanwhile, in the case of daytime on a sunny day, it may be difficult for pedestrians to recognize the lighting provided by the first lighting lamp. To prepare for this, a mist generating unit (not shown) may be further formed in the area around the first lighting lamp 120. The lighting irradiated from the first lighting lamp 120 may be reflected/scattered by mist to improve a pedestrian recognition rate in a daytime environment on a sunny day. It is preferable that the mist generation period in the mist generation unit is synchronized with the blinking period of the first lighting lamp 120. In addition, the mist generating unit may be connected to an existing water supply and spray mist when a heat wave exceeds a certain temperature to reduce the temperature around the crosswalk.

A first display 130 for displaying various types of information is formed on the rear surface of the vertical column member 100 (a surface in the direction of India). The first display 130 is composed of a touch screen, and provides information of various categories according to a selection of a pedestrian waiting for a signal. FIG. 3 illustrates that map information is displayed through the first display 130, and FIG. 4 illustrates that weather information is displayed through the first display 130.

A speaker 140 is formed on the side of the vertical column member 100. The speaker 140 is synchronized with the pedestrian traffic light to emit a guide sound for guiding pedestrians crossing the road when the pedestrian traffic light is changed from red to green, and when it is converted from green to red, a warning sound for guiding crossing prohibition is emitted. In some cases, the auxiliary speaker 141 may be installed at a location spaced apart from the traffic light. FIG. 5 illustrates that a warning sound for guiding crossing is emitted while waiting for a crosswalk, and FIG. 6 illustrates that a pedestrian traffic light is switched from red to green to emit a guide sound for guiding pedestrians to cross the road. have.

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

The inclined column member 200 is formed to be inclined at a predetermined angle from the upper end of the vertical column member 100. A second lighting lamp 220 is formed on the inclined pillar member 200. When the pedestrian traffic light turns green, the second lighting light 220 arouses the attention of the vehicle driver on the crosswalk and irradiates a light that guides the pedestrian crossing the road. The second lighting 220 is mainly intended to draw attention of the vehicle driver, and it is preferable to irradiate white light or red light. Fig. 5 exemplifies irradiation of white light and Fig. 10 red light.

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

As described above, the complex traffic light according to an embodiment of the present invention has a design that improves aesthetics, can provide various information, and can improve the safety of pedestrians.

Next, a complex 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 complex traffic light device according to the second embodiment of the present invention is installed on the sidewalk of a road where a crosswalk is formed, and FIG. 13 is a view showing a complex traffic light device according to a second embodiment of the present invention. It is a side view.

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

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

The sensor unit 150 detects a vehicle traveling on a road. The sensor unit 150 mainly detects a driving vehicle at a point in time when the walking traffic light changes from red to green.

The sensed sensing information is transmitted to the controller, and the controller calculates the speed of the vehicle approaching the traffic light and the distance between the traffic light and the vehicle using the sensing information. 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 returns a time and intensity of the scattered or reflected laser, a change in frequency, and a polarization state. It may be a LiDAR (Light Detection And Ranging) sensor that measures the distance and speed of the object to be measured from changes.

The control unit compares the calculated speed versus distance of the vehicle with a preset reference value at the time when the walking traffic light 110 switches from red to green, and if the calculated vehicle distance versus speed is greater than a preset reference value, the vehicle is Even if it turns green, it is highly 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 vehicle approaching the pedestrian crossing. In addition, the control unit controls the blocking bar 160 to go down, thereby providing a visual signal to the pedestrian, thereby temporarily stopping pedestrians from walking on the crosswalk to reduce the risk of an accident.

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

The control unit compares the vehicle distance-to-distance speed with a preset reference value at the time when the walking traffic light 110 is switched from red to green, and when the vehicle distance-to-distance speed is greater than a preset reference value, the pedestrian traffic light 110 is converted to green. By delaying the occurrence, it is possible to prevent an accident from occurring by a vehicle driving ignoring the signal. At this time, only the signal conversion of the pedestrian traffic light 110 is delayed, and the signal conversion of the vehicle traffic light 310 may be performed as it is.

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

Next, a complex 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 illustrating a complex 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 includes a vertical column member 100, an inclined column member 200, a horizontal column member 300, and walking It includes a signal lighting member 400. The vertical column member 100, the inclined column member 200, and the horizontal column member 300 are substantially the same as those of the first and second embodiments described above. However, in this third embodiment, it further includes a walking signal lighting member 400.

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 column member 100, the inclined column member 200, and the horizontal column member 300. ) And a floor lighting 420 that irradiates red or green light from the lower surface of the lighting bar 410 toward the floor of the sidewalk.

The floor light 420 is synchronized with the pedestrian traffic light 110 to irradiate green light toward the floor of the sidewalk when the walking traffic light 110 is green (see FIG. 14), and when the walking traffic light 110 is red, the floor of the sidewalk Red light is irradiated in the direction (see FIG. 15) so that the current signal state can be checked even through the floor.

The control unit controls the pedestrian traffic light 110, the vehicle traffic light 310, and the floor light 420 in connection with each other, and the walking signal light 110 and the floor light 420 are synchronized to switch signals.

The control unit compares the distance-to-distance speed of the vehicle with a preset reference value at the time when the walking traffic light 110 is switched from red to green, and if the speed-to-distance speed of the vehicle is greater than a preset reference value, the pedestrian traffic light 110 and the floor light ( By delaying the transition of 420 to green, it is possible to prevent an accident from occurring by a vehicle driving ignoring the signal. At this time, only the signal conversion of the pedestrian traffic light 110 and the floor light 420 is delayed, and the signal conversion of the vehicle traffic light 310 may be performed as it is.

Current floor traffic lights simply display traffic light information by switching red/green in connection with pedestrian traffic lights, and do not reflect information on vehicles approaching a crosswalk. Therefore, if the Smombi walking while looking at the smartphone checks the green signal through the floor traffic light and walks immediately, there is a very high possibility of a traffic accident caused by a vehicle approaching the crosswalk at 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 crosswalk at a high speed, a vehicle running ignoring the signal by delaying the conversion of the signal to green This can prevent accidents from occurring. In addition, since the floor lighting 420 is not buried in the ground, installation is simple and installation cost can be reduced.

In the above, embodiments of the present invention have been described, but those of ordinary skill in the art will add, change, delete or add components within the scope not departing from the spirit of the present invention described in the claims. Various modifications and changes can be made to the present invention by means of the like, and it will be said that this is also included within the scope of the present invention.
