Abstract
Description
Technical Field
[0001] The present application relates to the technical field of traffic control equipment, and in particular to a traffic signal control device. Background Art
[0002] Traffic lights are a category of traffic safety products, serving as a crucial tool for strengthening road traffic management, reducing traffic accidents, improving road efficiency, and improving traffic conditions. They are used at intersections such as crosses and T-junctions, controlled by traffic signal controllers to guide vehicles and pedestrians through the intersection in a safe and orderly manner. The timing of the different colored lights in traffic lights is primarily determined by factors such as local traffic volume and road conditions. These factors are primarily based on an analysis of historical data, often prioritizing the needs of motor vehicles over pedestrians. Consequently, the green light duration for the roadway is often significantly longer than that for the sidewalk. When there are many pedestrians crossing the road but little or no traffic on the roadway, pedestrians still have to wait for the traffic light to turn red before the sidewalk light turns green, which can affect intersection efficiency. In addition, in order to ensure the safety of pedestrians on urban roads, pedestrian waiting areas are usually located in special safety islands. Greening facilities are set up on both sides of the safety islands. On the one hand, they can beautify the road, and on the other hand, they can protect pedestrians on the safety islands. When there are many pedestrians waiting on the safety islands, some pedestrians may not wait for the sidewalk signal to turn green and cross the intersection. If a car passes by at this time, a traffic accident is likely to occur. Utility Model Content

[0017] This application provides an intelligent passenger flow camera on each side of the traffic light set in the pedestrian waiting area, and one of the two intelligent passenger flow cameras faces the zebra crossing of the driving lane, and the other faces the pedestrian waiting area. When pedestrians walk into the pedestrian waiting area, they will be captured by the intelligent passenger flow camera facing the pedestrian waiting area.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.
[0023] like Figure 1 and Figure 2 FIG. 1 shows a traffic signal control device disclosed in the present application, comprising a vertical pole 1, which is vertically arranged on the ground. A horizontal crossbar 2 is fixedly connected to one side of the middle position of the vertical pole 1, and the axis of the horizontal crossbar 2 is parallel to the roadway in front of the pedestrian waiting area 11. A traffic light 3 is hung in the middle position of the horizontal crossbar 2, and the traffic light 3 faces the pedestrian waiting area 11 on the opposite side.
[0024] An intelligent passenger flow camera 4 is respectively provided on one opposite side of the traffic light 3 along the axis direction of the horizontal crossbar 2. The two intelligent passenger flow cameras 4 are fixedly mounted on the horizontal crossbar 2, and the two intelligent passenger flow cameras 4 are electrically connected to the control system of the traffic light 3; the lens end of one of the intelligent passenger flow cameras 4 is facing the pedestrian waiting area 11 at the installation position of the vertical pole 1, and the lens end of the other intelligent passenger flow camera 4 is facing the zebra crossing on the road ahead.
[0025] In the above embodiments, to ensure pedestrian safety at intersections, special safety islands are typically set up on both sides of the roadway. The pedestrian waiting area 11 is located on the safety islands, and a signal light for observing pedestrians on the opposite side is erected on the safety island (the function of the traffic light 3 in this application is the same as that of the traffic light 3). The control systems of these signal lights are arranged together with the control system of the signal lights for observing vehicles on the roadway, so that they can work together when in use. That is, when the traffic light turns red, the pedestrian waiting area 11 will turn green, and when the pedestrian waiting area 11 turns red, the traffic light will turn green. The intelligent passenger flow camera 4 of this application is electrically connected to the control system of the traffic light 3 in the pedestrian waiting area 11. Therefore, when the intelligent passenger flow camera 4 transmits a light change signal to the traffic light 3 in the pedestrian waiting area 11, the signal light for observing vehicles on the roadway will also change synchronously.
[0026] In addition to the traditional snapshot monitoring function, the intelligent passenger flow camera 4 can also count and statistically analyze the monitored people and vehicles through visual recognition technology. For example, Hikvision's multi-dimensional passenger flow cylindrical camera can realize these functions. The specific principle of this device is a prior art and will not be described in detail. The vertical pole 1 of the present application can be installed on one side of the pedestrian waiting area 11 when in use, so that the traffic light 3 in the middle position of the horizontal crossbar 2 on the vertical pole 1 that is close to the width of the pedestrian waiting area 11 can be better observed by pedestrians when in use. One of the intelligent passenger flow cameras 4 set on the horizontal crossbar 2 faces the pedestrian waiting area 11, which is convenient for it to observe and count the number of pedestrians in the pedestrian waiting area 11 in real time. The other intelligent passenger flow camera 4 set on the horizontal crossbar 2 faces the zebra crossing on the driving lane, which is convenient for it to observe and count the real-time traffic flow at the intersection and the passage of pedestrians on the zebra crossing.
[0027] When the traffic light on the driving lane is green and the traffic light 3 in the pedestrian waiting area 11 is red, the intelligent passenger flow camera 4 facing the driving lane monitors that the traffic volume passing through the intersection is decreasing (the intelligent passenger flow camera 4 calculates the traffic volume of the driving lane by counting the number of vehicles passing through its monitoring area per unit time, and this technology is part of its function), and the intelligent passenger flow camera 4 facing the pedestrian waiting area 11 monitors that the number of pedestrians in the pedestrian waiting area 11 increases to a specific value (such as when there are more than ten pedestrians waiting in the pedestrian waiting areas 11 on both sides of the driving lane) or the pedestrian waiting time in the pedestrian waiting area 11 reaches a specific value (such as when the pedestrian waiting time is less than the remaining time of the green light on the driving lane but greater than five seconds), the intelligent passenger flow camera 4 will simultaneously transmit the information they obtain to the control system of the traffic light 3. At this time, the control system of the traffic light 3 can send the information to the traffic light and The traffic light 3 in the pedestrian waiting area 11 transmits a light-changing signal at the same time. The traffic light on the driving lane will change from green to yellow and then to red. The traffic light 3 in the pedestrian waiting area 11 will change from red to yellow and then to green (in actual application, a few seconds can be added before the traffic light on the driving lane changes from green to yellow, so as to give car drivers on the driving lane a certain buffer time). At this time, pedestrians can pass through the intersection under the guidance of the traffic light 3. During this process, the intelligent passenger flow camera 4 of this application can also monitor the situation of pedestrians crossing the road. If there are continuous pedestrians crossing the road, the traffic light on the driving lane can remain red, and the traffic light 3 in the pedestrian waiting area 11 can remain green to ensure that pedestrians can pass through the intersection safely. In this way, pedestrians do not have to wait for the green light signal in the pedestrian waiting area 11 when there are not many vehicles on the driving lane, thereby effectively improving the traffic efficiency of the intersection. Since pedestrians can efficiently cross the intersection after reaching the pedestrian waiting area 11, the risk of traffic accidents caused by pedestrians crossing the road prematurely without waiting for the traffic light to change due to insufficient traffic in the lane can be effectively reduced. Furthermore, pedestrians do not need to come into contact with the equipment during the entire process, which not only reduces the risk of human damage to the equipment but also improves hygiene by preventing cross-infection of viruses from contact between different people and the equipment.
[0028] When the intelligent passenger flow camera 4 facing the driving lane detects a high volume of vehicles on the driving lane and the intelligent passenger flow camera 4 facing the pedestrian waiting area 11 detects no pedestrians, it transmits a signal to the traffic light 3, causing the traffic light on the driving lane to remain green and the traffic light 3 in the pedestrian waiting area 11 to remain red, effectively alleviating road congestion. In other situations, the changing timing of the traffic lights on the driving lane and the traffic light 3 in the pedestrian waiting area 11 can be operated according to the normal settings.
[0029] The intelligent passenger flow camera 4 of the present application can also capture and record some uncivilized behaviors or accidents during use, so that the traffic police can better collect evidence when handling them.
[0030] Furthermore, if Figure 1 and Figure 2 As shown, an interception device 5 is provided on one side of the lower end of the pole 1. The interception device 5 is electrically connected to the control system of the traffic light 3. The interception device 5 can adjust its own state according to the changes of the traffic light 3 to realize the control of pedestrians in the pedestrian waiting area 11.
[0031] In the above embodiments, if a vehicle fails to obey traffic lights while driving on the road, the driver faces the risk of fines and driver's license deduction points. Therefore, vehicles rarely run red lights at intersections. However, in reality, the cost of running a red light for pedestrians and non-motor vehicles is relatively low. Especially at intersections without traffic police, some pedestrians or non-motor vehicles often fail to obey traffic lights 3 and cross the road recklessly, ultimately causing traffic accidents. To this end, the present application provides an interception device 5 at the pedestrian waiting area 11 in the above manner. When the traffic light 3 is red, the interception device 5 closes the passageway of the pedestrian waiting area 11, thereby preventing pedestrians or non-motor vehicles from entering the driving lane. When the traffic light 3 is green, the interception device 5 reopens the passageway of the pedestrian waiting area 11 to allow pedestrians and non-motor vehicles to pass normally. This effectively reduces the risk of traffic accidents caused by pedestrians or non-motor vehicles failing to obey traffic rules at intersections.
[0032] Furthermore, if Figure 1 and Figure 2 As shown, the interception device 5 is a fence gate.
[0033] In the above embodiment, the gate is a channel entrance and exit management interception device 5 specifically used for restricting the travel of vehicles or pedestrians on the road. Generally, the gate is divided into a straight-bar gate, a curved-arm gate and a fence gate. The straight-bar gate and the curved-arm gate will put their gate poles in a horizontal state when intercepting. Although this can intercept non-motor vehicles, there is still a certain height between the gate pole and the ground, which makes some pedestrians, especially minors of short stature, still have the risk of passing under the gate pole. The fence gate is composed of multiple horizontal bars and vertical bars. In addition to intercepting non-motor vehicles, it can also intercept pedestrians well when in use. Therefore, the interception device 5 of the present application selects the fence gate among the gates, and the control system of the fence gate is connected to the control system of the traffic light 3. When the traffic light 3 is green, a signal can be transmitted to the fence gate to make it raise the fence. When the traffic light 3 is red, a signal is transmitted to the fence gate to make it lower the fence, which can further reduce the risk of accidents at the intersection.
[0034] Furthermore, if Figure 1 and Figure 2 As shown, the lower end of the upright pole 1 is installed on the top of the chassis of the fence gate.
[0035] In the above embodiments, the upright pole 1 of the present application is installed on the top of the barrier gate chassis, which can make the entire device more compact and reduce the space occupied by the pedestrian waiting area 11.
[0036] Furthermore, if Figure 1 and Figure 2 As shown, an auxiliary support rod 6 is provided at intervals on one side of the vertical pole 1, and a horizontal beam 7 is fixedly connected between the vertical pole 1 and the auxiliary support rod 6. A rain shelter 8 is connected to the side of the horizontal beam 7 facing the horizontal crossbar 2, and the rain shelter 8 is located directly above the pedestrian waiting area 11.
[0037] In the above embodiment, the auxiliary support rod 6 and the vertical pole 1 can provide an installation basis for the rain shelter 8 through the horizontal beam 7. The rain shelter 8 is located directly above the pedestrian waiting area 11, which can shield the pedestrians in the pedestrian waiting area 11 from rain, snow and scorching sun, thereby improving the comfort of pedestrians while waiting for passage.
[0038] Furthermore, if Figure 1 and Figure 2 As shown, the upper sides of the horizontal beam 7 and the rain shield 8 are fixedly connected through a plurality of traction wires 9 and the upper ends of the vertical poles 1 and the auxiliary support poles 6.
[0039] In the above embodiment, the upper ends of the auxiliary support rods 6 and the vertical rods 1 are connected to the rain shelter 8 and the horizontal beam 7 through multiple traction wires 9. This can improve the stability of the entire equipment during use and prevent the rain shelter 8 from overturning and hitting pedestrians in rainy, snowy or windy weather.
[0040] Furthermore, if Figure 1 and Figure 2 As shown, the vertical heights of the intelligent passenger flow camera 4 and the traffic light 3 are both lower than the rain shield 8 , and the projections of the intelligent passenger flow camera 4 and the traffic light 3 on the horizontal plane both fall within the projection of the rain shield 8 on the horizontal plane.
[0041] In the above embodiments, the rain shelter 8 of the present application is set up in the above manner. During use, in addition to shielding pedestrians in the pedestrian waiting area 11 from rain, snow and sun, it can also protect the smart passenger flow camera 4 and the traffic light 3, preventing rain and snow from adhering to the smart passenger flow camera 4 and the traffic light 3 and affecting the use effect, and it can also prevent the smart passenger flow camera 4 and the traffic light 3 from being exposed to the sun for a long time and reducing their service life.
[0042] Furthermore, if Figure 1 and Figure 2 As shown, a solar panel 10 is provided on the upper side of the rain shield 8 .
[0043] In the above embodiment, the upper space of the awning 8 is utilized to lay the solar power generation panel 10, which can effectively utilize the sunlight irradiated thereon during use and convert it into electrical energy. The generated electrical energy is not only clean and environmentally friendly, but also can effectively save electricity costs after being utilized.
[0044] The working principle of this embodiment is as follows: When the device of this application is used at an intersection, if the intelligent passenger flow camera 4 monitors that the traffic flow in the driving lane is low, while the traffic flow in the pedestrian waiting area 11 is high or the pedestrian waiting time is long, the intelligent passenger flow camera 4 will send a signal to the traffic light 3, causing the traffic light 3 on the horizontal crossbar 2 to turn green in advance. At the same time, the intelligent passenger flow camera 4 will control the barrier gate to raise the barrier to guide pedestrians through the intersection. The traffic light on the driving lane will simultaneously turn red, suspending the traffic in the driving lane. When pedestrians cross the zebra crossing on the driving lane, the intelligent passenger flow camera 4 facing the driving lane will continue to monitor the pedestrian situation on the zebra crossing. After all pedestrians have passed the driving lane, it will send a signal to the traffic light 3 again, causing the traffic light 3 in the pedestrian waiting area 11 to turn red and the traffic light on the driving lane to turn green. When the intelligent passenger flow camera 4 facing the driving lane detects a high volume of vehicles on the driving lane, and the intelligent passenger flow camera 4 facing the pedestrian waiting area 11 detects no pedestrians, it can transmit a signal to the traffic light 3, causing the traffic light on the driving lane to remain green and the traffic light 3 in the pedestrian waiting area 11 to remain red, effectively alleviating road congestion. In other cases, the change time of the traffic light on the driving lane and the traffic light 3 in the pedestrian waiting area 11 can be operated according to the normal setting value. The traffic light 3 of the present application can adjust the duration of the red and green lights in real time according to the actual situation of the intersection, effectively improving the traffic efficiency of the intersection.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
