Description

Technical Field

[0001] The present application relates to the field of intelligent transportation technology, and specifically to a non-motorized vehicle lane traffic light control system, method and storage medium. Background Art

[0002] There is a great deal of uncertainty when non-motor vehicles on non-motorized vehicle lanes cross the road. The specific manifestations include: whether the non-motorized vehicle crosses the road along the current non-motorized vehicle lane, whether the non-motorized vehicle passes when the traffic light corresponding to the current non-motorized vehicle lane indicates that the vehicle can pass, etc. In addition, with the increase in traffic pressure, the number of non-motorized vehicles passing through is also increasing. Therefore, the control of non-motorized vehicles crossing the road has become as important and necessary as the control of motor vehicle traffic.

[0003] Traditional non-motorized vehicle lane traffic light control is implemented based on the communication of motor vehicle lane traffic lights. This method relies on motor vehicle flow and motor vehicle traffic pressure. However, since non-motorized vehicle lanes are generally narrow and mostly one-way streets, non-motorized vehicle traffic pressure is more likely to increase with the increase in vehicle flow. Therefore, simply controlling non-motorized vehicle lane traffic lights synchronously with motor vehicle traffic lights is not very effective in alleviating non-motorized vehicle traffic pressure.

[0031] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] In this article, the term "comprising" is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] This embodiment discloses Figure 1 A non-motorized lane traffic light control system is shown, comprising a vehicle flow detection module, a motor vehicle lane light control module and a non-motorized lane light control module.

[0034] Specifically, the vehicle flow detection module is arranged at each non-motor vehicle lane and is configured to: monitor the non-motor vehicle flow at both ends of the corresponding non-motor vehicle lane and obtain non-motor vehicle flow data;

[0035] Specifically, the motor vehicle lane light control module is configured to: collect the light control time of the motor vehicle lane traffic light to obtain the motor vehicle lane traffic light data;

[0036] Specifically, the non-motorized vehicle lane light control module is configured to control the non-motorized vehicle lane traffic lights set at both ends of the non-motorized vehicle lane based on the non-motorized vehicle flow data and the motor vehicle lane traffic light data; wherein, when the non-motorized vehicle flow data reaches the corresponding determination threshold, the non-motorized vehicle lane light control module sends a delay instruction to the motor vehicle lane light control module and the non-motorized vehicle lane traffic light, so that the red light display time of the traffic light corresponding to the motor vehicle lane passing through the non-motorized vehicle lane is delayed, and the green light display time of the non-motorized vehicle lane traffic light is delayed. It should be noted that when the red light display time of the traffic light corresponding to the motor vehicle lane passing through the non-motorized vehicle lane is adjusted, the corresponding traffic light corresponding to the motor vehicle lane in the same direction as the non-motorized vehicle lane is adjusted synchronously with the traffic light of the non-motorized vehicle lane, for example, the traffic light corresponding to the motor vehicle lane in the same direction as the non-motorized vehicle lane corresponds to a straight-line traffic state and / or corresponds to a turning traffic state in the opposite direction to the non-motorized vehicle lane.

[0037] In this embodiment, the vehicle flow detection module includes an image acquisition unit and a vehicle flow counting unit.

[0038] Specifically, the image acquisition unit is configured to acquire images of both ends of the non-motorized vehicle lane.

[0039] Specifically, the vehicle flow counting unit is configured to count the number of non-motor vehicles based on the collected images and obtain non-motor vehicle flow data. Among them, the image acquisition unit receives the corresponding non-motor vehicle lane traffic light control time fed back by the non-motor vehicle lane light control module, and the image acquisition unit executes the image acquisition instruction to collect images during the time from the end of one green light to the next green light of the non-motor vehicle lane traffic light. Preferably, the non-motor vehicle flow data is obtained based on the image count collected at the time point of ΔT time before the next green light is on. In order to improve the accuracy of the non-motor vehicle flow data, the ΔT time can be adjusted according to the vehicle inventory of the non-motor vehicle lane. Similarly, the range of image acquisition can also be adjusted according to the normal traffic pressure of the non-motor vehicle lane. Even the non-motor vehicle flow data of the non-motor vehicle lane can be obtained through multiple image acquisition methods. For this application, all methods that can accurately obtain the non-motor vehicle flow data of the non-motor vehicle lane can be adopted, and any technical means in the prior art that can achieve this purpose can be adopted.

[0044] Furthermore, the congestion coefficient corresponding to the collected non-motor vehicle flow data is obtained by comparing the collected non-motor vehicle flow data with a preset congestion time coefficient criterion library, wherein the congestion time coefficient criterion library stores the congestion coefficient values ​​corresponding to the maximum non-motor vehicle flow that can be passed through the corresponding non-motor vehicle lane within the standard green light lighting time and the incremented non-motor vehicle flow value range, wherein when the collected non-motor vehicle flow data is less than or equal to the maximum non-motor vehicle flow, ρ is 0. For example: assuming that the maximum number of non-motor vehicle traffic that can pass within the standard green light lighting time is 20, when the detected non-motor vehicle traffic data is 15, then ρ is 0; when the detected non-motor vehicle traffic data is 25, then ρ is 1.2; when the detected non-motor vehicle traffic data is 20, then ρ is 1.5, and so on. The value of ρ can be set comprehensively based on the width of the non-motor vehicle lane, the length of the non-motor vehicle lane, the motor vehicle traffic pressure of the road section, the non-motor vehicle traffic pressure of the road section, etc. The purpose is to adaptively increase the travel time of non-motor vehicles, thereby reasonably alleviating the travel pressure of non-motor vehicles.
