Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of traffic signal control, in particular to a car yielding to pedestrian auxiliary signal lamp control system. BACKGROUND

[0002] In recent years, according to the provisions of the Road Traffic Safety Law of the People's Republic of China, through positive incentives and negative punishment measures, the "car yielding to pedestrian" is normalized to reflect the priority of pedestrian traffic and protect the safety of pedestrians.

[0003] However, the actual effect of "car yielding to pedestrian" is not ideal. On the one hand, traffic accidents still occur from time to time, and on the other hand, there are great individual differences among drivers, and the cost of illegal behavior is also different. Therefore, only public buses and taxis can strictly implement "car yielding to pedestrian", and private cars are prone to have a lucky mentality. Such differences make the traffic situation on the zebra crossing more complex. Therefore, more facilities are needed to guide and assist the implementation of the "car yielding to pedestrian" regulation.

[0004] From the perspective of pedestrians, there are a large number of zebra crossings without traffic lights in densely populated areas of cities. At these zebra crossings, there is often a large visual blind spot from the perspective of pedestrians, as shown in Figure 1 The line of sight of the pedestrian is blocked by the vehicle on lane 1. Although the vehicle on lane 1 has stopped, the pedestrian cannot determine whether the vehicles on lane 2 and lane 3 are willing to slow down for pedestrians. At this time, the pedestrian often stops on the roadside or observes on lane 1 until it is determined that all lanes are safe to pass through. However, this observation often takes a long time, which increases the speed of pedestrians passing through the sidewalk, thereby causing congestion and hindering traffic.

[0005] From the perspective of vehicles, during the rush hour, the traffic volume is very large, but pedestrians crossing the road are often scattered, and pedestrians also need to observe whether the road conditions are safe to pass through quickly.

[0006] Example 1 is a car yielding to pedestrian guidance control system disclosed in Chinese Utility Model Patent No. CN209486912U, as shown in Figure 2 The system sets up detection doors and detectors on both sides of the zebra crossing and at the center of the intersection, and sets up an alarm at the center of the intersection. When a vehicle or a pedestrian is detected, the alarm will alarm. This technical solution cannot solve the problem of more non-intersection crossings without traffic lights, and the vehicle has a speed when passing through the intersection. When the detection door detects a vehicle and a pedestrian in the intersection, it triggers the alarm, and a traffic accident has often occurred.

[0007] Example 2 is a courtesy pedestrian light blanket system based on a microlens array and a control method thereof disclosed in Chinese Invention Patent No. CN114228608A, as shown in Figure 3As shown, by sending a request to the car host by the driver, the light source module accepts and executes the lighting instruction to project on the pedestrian crossing to alert pedestrians. The technical solution has the problem of low efficiency as the traditional traffic light needs to be manually set to control the mode.

[0008] Example 3, the Chinese utility model patent with the publication number CN211578047U discloses a control system of a road surface signal lamp, like Figure 3 As shown, by setting the road surface signal lamp embedded in the ground on the road surface, the technical solution plays a guiding and warning role. However, the technical solution has the problem of needing to rely on the self-consciousness of the driver to play a warning role. Utility model content

Figure 5

[0039] Preferably, the preset distance is greater than the safe braking distance of the motor vehicle, so as to ensure that the motor vehicle has sufficient braking distance.

[0046] Figure 6 A schematic diagram of installation of a vehicle-to-pedestrian auxiliary signal lamp control system according to an embodiment of the present disclosure.

[0047] As shown in the figure, the weighing sensor 507 is arranged at the starting point of the pedestrian crossing, the second communication module 506 and the second microprocessor 505 are arranged on the pedestrian crossing, and the vehicle signal lamp 508 is arranged on the lane between the ground inductance loop speed measuring device 501 and the pedestrian crossing. Figure 6 ​As shown, the pedestrian signal lamp 504 is arranged at the position corresponding to each lane on the pedestrian crossing, and the vehicle signal lamp 508 is arranged on each lane between the ground inductive coil speed measuring device 501 and the pedestrian crossing. That is, in the embodiment, a plurality of pedestrian signal lamps are arranged on the pedestrian crossing, and the number and arrangement position of the pedestrian signal lamps correspond to the number and position of the lanes respectively, so that the vehicle on each lane can clearly observe the pedestrian situation on the pedestrian crossing through the pedestrian signal lamp arranged on the corresponding lane.

[0048] The function and working process of the vehicle-to-pedestrian auxiliary signal lamp control system provided by the embodiment of the present disclosure will be described in detail below.

[0049] The vehicle-to-pedestrian auxiliary signal lamp control system provided in the present disclosure can realize two functions:

[0050] First, guide pedestrians to pass quickly, and the implementation process is as follows Figure 7 As shown.

[0051] When a vehicle is at a distance L (L >= motor vehicle safe braking distance) from the pedestrian crossing, the ground inductive coil speed measuring device 501 under the corresponding lane obtains the current speed and state of the vehicle, and sends the current speed and state of the vehicle to the first microprocessor 502. The first microprocessor 502 analyzes the current speed and state of the vehicle to determine whether the current lane meets the safety requirements. When the safety requirements are met, the first microprocessor 502 sends a prohibition passing instruction to the first communication module 503. The first communication module 503 receives the prohibition passing instruction and sends a prohibition passing signal to the second communication module 506. The second communication module 506 receives the prohibition passing signal and sends it to the second microprocessor 505. The second microprocessor 505 receives the prohibition passing signal and controls the pedestrian signal lamp 504 to issue a prohibition passing signal. Conversely, when the vehicle meets the safety requirements or the lane is empty, the first microprocessor 502 sends an allow passing instruction to the first communication module 503. The first communication module 503 receives the allow passing instruction and sends an allow passing signal to the second communication module 506. The second communication module 506 receives the allow passing signal and sends it to the second microprocessor 505. The second microprocessor 505 receives the running passing signal and controls the pedestrian signal lamp 504 to issue an allow passing signal. In this way, the pedestrian can quickly and safely pass through the pedestrian crossing when encountering a blind area.

[0052] Second, guide vehicles to give way to pedestrians, and the implementation process is as follows Figure 8 As shown.

[0053] The mass information of the current sidewalk is obtained by the weighing sensor 507 installed in the pedestrian waiting area beside the sidewalk, and is sent to the second microprocessor 505. The second microprocessor 505 judges whether the current vehicle needs to yield to the pedestrian by analyzing the mass information. When it is determined that the vehicle needs to yield to the pedestrian, the second microprocessor 505 sends a control vehicle yielding to pedestrian instruction to the second communication module 506. The second communication module 506 sends a vehicle yielding to pedestrian signal to the first communication module 503 after receiving the control vehicle yielding to pedestrian instruction. The first communication module 503 sends the vehicle yielding to pedestrian signal to the first microprocessor 502. The first microprocessor 502 controls the vehicle signal lamp 508 to send a deceleration signal according to the vehicle yielding to pedestrian signal, so as to guide the vehicle to yield to the pedestrian. Conversely, when it is determined that the vehicle does not need to yield to the pedestrian, the second microprocessor 505 sends a control vehicle passing instruction to the second communication module 506. The second communication module 506 sends a vehicle passing signal to the first communication module 503 after receiving the control vehicle passing instruction. The first communication module 503 sends the vehicle passing signal to the first microprocessor 502. The first microprocessor 502 controls the vehicle signal lamp 508 to send a communication signal according to the vehicle passing signal, so as to guide the vehicle to pass.
