Description

Technical Field

[0001] The present application relates to, but is not limited to, the technical field of traffic light control, and in particular to a method, device, electronic device, and medium for controlling a traffic light. Background Art

[0002] Currently, pole-mounted traffic lights are commonly deployed at intersections. These lights include a vehicle-directed signal light for vehicles and a pedestrian-directed signal light for pedestrians. These lights display traffic signals according to pre-set rules, instructing vehicles and pedestrians at the intersection to proceed or wait, allowing for orderly passage. During each traffic signal cycle, a signal controller controls the lights to display traffic signals according to a pre-set sequence of traffic signal phases. A traffic signal cycle can include multiple traffic signal phases, each of which indicates a passable lane and a non-passable lane. When a queued vehicle sees that the traffic signal indicates their lane is passable, the vehicle owner can proceed through the intersection. However, the pedestrian-directed signal lights are typically synchronized with the motor vehicle-directed signal lights, requiring a full red light for both the straight and left turn signals on an entrance lane. This can lead to pedestrians waiting too long and potentially running red lights, resulting in conflicts between pedestrians and vehicles, posing a safety hazard. Summary of the Invention

By introducing a ground signal light, all first ground signal lights, second ground signal lights, and pole-type pedestrian signal lights can be collaboratively controlled based on target signal light instructions to reduce safety hazards.

[0028] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0029] It is understood that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and the like in the specification, claims, or accompanying drawings are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0030] Currently, pole-type traffic lights are usually deployed at road intersections. Pole-type traffic lights include vehicle traffic lights and pedestrian traffic lights. Pole-type traffic lights display traffic signals according to preset rules to instruct vehicles and pedestrians at the road intersection to pass or wait, so that vehicles and pedestrians at the road intersection can pass in an orderly manner.

[0031] In each traffic signal cycle, the signal controller controls the traffic lights to display traffic signals according to the preset operating sequence of each traffic signal phase, wherein a traffic signal cycle may include multiple traffic signal phases. A traffic signal phase is a state in which the traffic signal does not change, and is used to indicate passable lanes and non-passable lanes. When the owner of the queuing vehicle observes that the traffic signal indicates that the lane where his vehicle is located is a passable lane, the owner can drive the vehicle through the road intersection.

[0032] However, the pole-mounted signal lights that instruct pedestrians to cross the sidewalk are usually synchronized with the pole-mounted signal lights for motor vehicles. Pedestrians can only pass when the straight-ahead and left-turn signals on a certain entrance are all red. This causes pedestrians to wait too long and run red lights, leading to conflicts between pedestrians and vehicles, thus posing a safety hazard.

[0033] To solve the above-mentioned problems, an embodiment of the present application provides a signal light control method, which can introduce ground signal lights and coordinately control all first ground signal lights, second ground signal lights and pole-type pedestrian signal lights based on target signal light instructions to reduce safety hazards.

[0034] The signal light control method of an embodiment of the present application is applied to a signal light control system, which is communicatively connected to a first ground signal light, a second ground signal light, and a pole-type pedestrian signal light located at an intersection. The first ground signal light is located on both sides of the sidewalk at the intersection, and the second ground signal light is located in a left-turn waiting area near the sidewalk.

[0035] Reference Figure 1 A flowchart of a method for controlling a signal light according to an embodiment of the present application is provided. The method includes but is not limited to the following steps:

[0036] Step S101, determining multiple target phases corresponding to a signal light control system, and determining reference signal light information of pole-type pedestrian signal lights of different traffic directions corresponding to each target phase;

[0037] Step S102, determining target signal light information of the first ground signal light and the second ground signal light corresponding to each target phase based on the reference signal light information;

[0038] Step S103: For any target phase, the reference signal light information is associated with the target signal light information to obtain a target signal light instruction, and the first ground signal light, the second ground signal light and the pole-type pedestrian signal light are collaboratively controlled based on the target signal light instruction.

[0039] Therefore, the embodiment of the present application determines multiple target phases corresponding to the signal light control system, and determines the reference signal light information of the pole-type pedestrian signal lights of different traffic directions corresponding to each target phase, and determines the target signal light information of the first ground signal light and the second ground signal light corresponding to each target phase based on the reference signal light information. For any target phase, the reference signal light information is associated with the target signal light information to obtain the target signal light instruction, and all the first ground signal lights, the second ground signal lights and the pole-type pedestrian signal lights are collaboratively controlled based on the target signal light instruction. The present application can introduce ground signal lights and collaboratively control all the first ground signal lights, the second ground signal lights and the pole-type pedestrian signal lights based on the target signal light instruction, so that when a vehicle enters the left-turn waiting area, it can determine whether the lane is passable through the first ground signal lights and the second ground signal lights, thereby improving the recognition of the operating rules of the left-turn waiting area and reducing safety hazards.

[0040] In some embodiments, the traffic light control system can collect traffic data such as traffic flow, vehicle speed, and queue length through sensors at the intersection (such as geomagnetic sensors, video surveillance equipment, microwave radar, etc.); determine the selected target phase based on the traffic data; associate the reference traffic light information with the target traffic light information based on the target phase to obtain the target traffic light instruction, and coordinately control all ground traffic lights and pole-type traffic lights based on the target traffic light instruction. In other embodiments, when the traffic light control system detects an abnormal situation (such as a traffic light failure, increased traffic congestion, etc.), the traffic light control system will issue an alarm and adjust the target traffic light control instructions for the ground traffic lights and pole-type traffic lights according to a preset emergency plan. Those skilled in the art can choose the specific implementation of the traffic light control system according to actual needs.

[0041] It is understandable that in the prior art, traffic lights indicating vehicle traffic are typically pole-mounted. In rainy and foggy weather, it is difficult to distinguish between distant pole-mounted traffic lights and those indicating pedestrian traffic, causing vehicles to misjudge traffic lights, thereby posing a safety hazard. The present embodiment introduces ground-mounted traffic lights on both sides of the sidewalk, placing them closer than pole-mounted traffic lights. This reduces the likelihood of vehicles misjudging traffic lights, thereby alleviating safety hazards.

[0042] It should be understood that in the embodiments of the present application, the reference signal light information and target signal light information are signal light status information used as a control basis in the signal light control system. The reference signal light information and target signal light information may include phase duration, phase sequence, etc. Those skilled in the art may customize the reference signal light information and target signal light information based on actual needs. In other embodiments, the reference signal light information may be obtained through various methods, such as historical data, prediction rules, or traffic monitoring.

[0043] It is understood that in embodiments of the present application, a target signal light instruction can be input into a signal light controller to obtain a signal light voltage and current drive signal and a timing control signal. Based on the drive signal and timing control signal, the display state, phase duration, and phase switching sequence of the ground signal light and the pole signal light can be controlled. For example, if the target signal light instruction sets the state of the east-bound through signal light to green for 30 seconds, the target signal light instruction is input into the signal light controller of the east-bound through signal light, causing the east-bound through signal light to switch to green and set a timer for 30 seconds. When 30 seconds have passed, control is performed according to the target signal light control instruction corresponding to the phase sequence in the target signal light instruction.

[0044] In some embodiments, the intersection includes an eastbound entrance road, an eastbound exit road, a westbound entrance road, a westbound exit road, a southbound entrance road, a southbound exit road, a northbound entrance road, and a northbound exit road. The eastbound entrance road corresponds to a first left-turn waiting area, the westbound entrance road corresponds to a second left-turn waiting area, the southbound entrance road corresponds to a third left-turn waiting area, and the northbound entrance road corresponds to a fourth left-turn waiting area. When the target phase is that the straight lanes of the eastbound entrance road and the westbound entrance road are passable, the sidewalks of the eastbound entrance road and the westbound entrance road are prohibited from passing, left-turning vehicles in the eastbound entrance road can enter the first left-turn waiting area, left-turning vehicles in the westbound entrance road can enter the second left-turn waiting area, all lanes of the southbound entrance road and the northbound entrance road are prohibited from passing, and the sidewalks of the southbound entrance road and the northbound entrance road are passable, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are cooperatively controlled based on the target signal light instruction, including:

[0045] The pole-type pedestrian signal lights corresponding to the eastbound entrance, eastbound exit, westbound entrance and westbound exit are red;

[0046] The first ground signal lights corresponding to the eastbound entrance and the westbound entrance are green;

[0047] The second ground signal light controlling the first left-turn waiting area and the second left-turn waiting area is red;

[0048] The pole-type pedestrian signal lights corresponding to the southbound entrance lane, southbound exit lane, northbound entrance lane and northbound exit lane are green;

[0049] The first ground signal lights corresponding to the southbound entrance and northbound entrance are red;

[0050] The second ground signal light controlling the third left-turn waiting area and the fourth left-turn waiting area is red.

[0051] Therefore, refer to Figure 2 As shown, the embodiment of the present application controls the first ground signal light 11, the third ground signal light 111, the fourth ground signal light 112, the second ground signal light 12, and the pole-type pedestrian signal light 20 corresponding to the eastbound entrance road to green lights while controlling the first left-turn waiting area to red lights, thereby guiding vehicles in the left-turn lane of the eastbound entrance road into the first left-turn waiting area, so that the sidewalk in the first left-turn waiting area is blocked by vehicles, reducing the situation where pedestrians ignore traffic rules and cross the sidewalk, thereby reducing safety hazards.

[0052] It can be understood that the embodiment of the present application controls the first ground signal light 11, the third ground signal light 111, the fourth ground signal light 112, the second ground signal light 12, and the pole-type pedestrian signal light 20 corresponding to the eastbound entrance lane to be green, while controlling the second ground signal light in the first left-turn waiting area to be red, thereby guiding vehicles in the left-turn lane to the left-turn waiting area, avoiding the vehicles in the left-turn lane from randomly parking or queuing on the sidewalk, thereby reducing the possibility of pedestrians crossing the sidewalk and colliding with vehicles. After the left-turning vehicle enters the left waiting area, the passage space of the sidewalk is clearer, and pedestrians can more intuitively judge the safe passage area, reducing the risk of line of sight obstruction and misjudgment caused by vehicles occupying the road, and reducing safety hazards.

[0053] In some embodiments, the first ground signal light includes a third ground signal light and a fourth ground signal light, the third ground signal light is located on both sides of the sidewalk away from the left-turn waiting area, and the fourth ground signal light is located on both sides of the sidewalk close to the left-turn waiting area. When the target phase is that the through lane of the eastbound entrance road and the through lane of the westbound entrance road are passable, the left-turn lane of the eastbound entrance road and the left-turn lane of the westbound entrance road are prohibited from passing, the sidewalk of the eastbound entrance road in the area of the first left-turn waiting area is passable, and the sidewalk of the westbound entrance road is passable in the area of the second left-turn waiting area, all lanes of the southbound entrance road and the northbound entrance road are prohibited from passing, and the sidewalks of the southbound entrance road and the northbound entrance road are passable, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are cooperatively controlled based on the target signal light instruction, including:

[0054] The pole-type pedestrian signal lights corresponding to the eastbound and westbound entrances are yellow;

[0055] The pole-type pedestrian signal lights corresponding to the eastbound and westbound exits are red;

[0056] The third ground signal light corresponding to the eastbound entrance lane and the westbound entrance lane is green, and the fourth ground signal light is red;

[0057] Control the second ground signal lights corresponding to the first left waiting area and the second left waiting area to be red;

[0058] The pole-type pedestrian signal lights corresponding to the southbound entrance lane, southbound exit lane, northbound entrance lane and northbound exit lane are green;

[0059] The first ground signal light and the second ground signal light corresponding to the southbound entrance lane and the northbound entrance lane are red.

[0060] It is understandable that, referring to Figure 3 As shown, in the embodiment of the present application, the pole-type pedestrian signal light 20 corresponding to the eastbound entrance road is controlled to be a yellow light while the fourth ground signal light 112 corresponding to the eastbound entrance road is controlled to be a red light, so that the sidewalk of the eastbound entrance road can pass through the left turn waiting area. Compared with the prior art that requires the vehicle's straight and left turn indicators to be red at the same time before passing, the waiting time for pedestrians is reduced, the probability of pedestrians running red lights is reduced, and thus safety hazards are reduced. Therefore, the embodiment of the present application controls the pole-type pedestrian signal light 20 corresponding to the eastbound entrance road to be a yellow light while the fourth ground signal light 112 corresponding to the eastbound exit road is controlled to be red light, so that the sidewalk of the eastbound entrance road can pass through the first left turn waiting area, reducing the waiting time for pedestrians to cross the sidewalk and the probability of pedestrians running red lights, thereby reducing safety hazards.

[0061] In some embodiments, when the target phase is that the through lane of the eastbound entrance road and the through lane of the westbound entrance road are prohibited from passing, the left turn lane of the eastbound entrance road and the left turn lane of the westbound entrance road are passable, the sidewalk of the eastbound entrance road and the sidewalk of the westbound entrance road in the through lane area are passable, all lanes of the southbound entrance road and the northbound entrance road are prohibited from passing, and the sidewalks of the southbound entrance road and the northbound entrance road are passable, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are coordinated and controlled based on the target signal light instruction, including:

[0062] The pole-type pedestrian signal lights corresponding to the eastbound and westbound entrances are yellow;

[0063] The pole-type pedestrian signal lights corresponding to the eastbound and westbound exits are green;

[0064] The second and fourth ground signal lights corresponding to the eastbound and westbound entrances are controlled to be green;

[0065] The third ground signal light corresponding to the eastbound entrance lane and the westbound entrance lane is red;

[0066] The pole-type pedestrian signal lights corresponding to the southbound entrance and northbound entrance are green;

[0067] The pole-type pedestrian signal lights corresponding to the southbound and northbound exits are red;

[0068] The first ground signal light and the second ground signal light corresponding to the southbound entrance lane and the northbound entrance lane are red.

[0069] Therefore, the embodiment of the present application controls the second and fourth ground signal lights corresponding to the eastbound entrance lane to green lights, and controls the third ground signal light corresponding to the eastbound entrance lane to red lights, so that vehicles in the left-turn lane will not be interfered with by vehicles in the straight lane when turning left, thereby reducing safety hazards.

[0070] It is understandable that, referring to Figure 4 As shown, the embodiment of the present application controls the pole-type pedestrian signal light 20 corresponding to the eastbound entrance road to yellow light while controlling the third ground signal light 111 corresponding to the eastbound entrance road to red light, so that pedestrians in the eastbound entrance road can pass through the sidewalk of the straight lane. Compared with the prior art, which requires pedestrians to pass only when the straight and left turn indicators of the vehicle are red at the same time, the waiting time of pedestrians is reduced, the probability of pedestrians running red lights is reduced, and thus safety hazards are reduced.

[0071] In some embodiments, when the target phase is that all lanes of the eastbound entrance road and all lanes of the westbound entrance road are prohibited from passing, the sidewalks of the eastbound entrance road and the westbound entrance road are passable, the through lanes of the southbound entrance road and the northbound entrance road are passable, left-turning vehicles at the southbound entrance road can enter the third left-turn waiting area, north-turning vehicles at the northbound entrance road can enter the fourth left-turn waiting area, and the sidewalks of the southbound entrance road and the northbound entrance road are prohibited from passing, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are coordinated and controlled based on the target signal light instruction, including:

[0072] The pole-type pedestrian signal lights corresponding to the eastbound entrance, eastbound exit, westbound entrance and westbound exit are green;

[0073] The first and second ground traffic lights corresponding to the eastbound and westbound entrances are both red;

[0074] The pole-type pedestrian signal lights corresponding to the southbound entrance lane, southbound exit lane, northbound exit lane and northbound entrance lane are red;

[0075] The first ground signal lights corresponding to the southbound entrance and the northbound entrance are green;

[0076] The second ground signal light corresponding to the third left-turn waiting area and the fourth left-turn waiting area is red.

[0077] Therefore, the embodiment of the present application controls the pole-type pedestrian signal lights corresponding to the east-bound entrance road and the east-bound exit road to green lights while controlling the first ground signal light and the second ground signal light corresponding to the east-bound entrance road to red lights, so that when vehicles are prohibited from passing through the east-bound entrance road and the east-bound exit road, the sidewalk of the east-bound entrance road can be used, thereby reducing conflicts between vehicles and pedestrians when passing through the sidewalk and reducing safety hazards.

[0078] It is understandable that, referring to Figure 5 As shown, the embodiment of the present application controls the pole-type pedestrian signal lights 20 corresponding to the eastbound entrance road and the eastbound exit road to be green lights while controlling the first ground signal light 11 and the second ground signal light 12 corresponding to the eastbound entrance road to be red lights, thereby reducing the probability of collision between vehicles and pedestrians in all lanes of the eastbound entrance road when passing through the sidewalk, thereby reducing safety hazards.

[0079] In some embodiments, when the target phase is that all lanes of the eastbound entrance road and all lanes of the westbound entrance road are prohibited from passing, the sidewalks of the eastbound entrance road and the westbound entrance road are passable, the through lanes of the southbound entrance road and the northbound entrance road are passable, the left turn lanes of the southbound entrance road and the northbound entrance road are prohibited from passing, the sidewalk of the southbound entrance road is passable in the third left waiting area, and the sidewalk of the northbound entrance road is passable in the fourth left turn waiting area, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are coordinated and controlled based on the target signal light instruction, including:

[0080] The pole-type pedestrian signal lights corresponding to the eastbound entrance, eastbound exit, westbound entrance and westbound exit are green;

[0081] The first and second ground traffic lights corresponding to the eastbound and westbound entrances are both red;

[0082] The pole-type pedestrian signal lights corresponding to the southbound entrance and northbound entrance are yellow;

[0083] The pole-type pedestrian signal lights corresponding to the southbound and northbound exits are red;

[0084] The third ground signal lights corresponding to the southbound entrance and northbound entrance are green;

[0085] The second ground signal light corresponding to the southbound entrance lane and the northbound entrance lane is green and the fourth ground signal light is red.

[0086] It is understandable that, referring to Figure 6 As shown, the embodiment of the present application controls the pole-type pedestrian signal light 20 corresponding to the southbound entrance road to be a yellow light while controlling the second ground signal light 12 corresponding to the southbound entrance road to be a green light and the fourth ground signal light 112 to be a red light, so that the sidewalk of the southbound entrance road can pass through the left turn waiting area, reducing the waiting time for pedestrians to pass through the sidewalk and reducing the probability of pedestrians running a red light, thereby reducing safety hazards.

[0087] In some embodiments, when the target phase is that all lanes of the eastbound entrance road and the westbound entrance road are prohibited from passing, the sidewalks of the eastbound entrance road and the westbound entrance road are passable, the through lanes of the southbound entrance road and the northbound entrance road are prohibited from passing, the left turn lanes of the southbound entrance road and the northbound entrance road are passable, and the sidewalks of the southbound entrance road and the northbound entrance road in the through lane area are passable, the first ground signal light, the second ground signal light, and the pole-type pedestrian signal light are coordinated and controlled based on the target signal light instruction, including:

[0088] The pole-type pedestrian signal lights corresponding to the eastbound entrance and westbound entrance are green;

[0089] The pole-type pedestrian signal lights corresponding to the eastbound and westbound exits are red;

[0090] The first and second ground signal lights corresponding to the eastbound and westbound entrances are red.

[0091] The pole-type pedestrian signal lights corresponding to the southbound entrance and northbound entrance are yellow;

[0092] The pole-type pedestrian signal lights corresponding to the southbound and northbound exits are green;

[0093] The second and fourth ground signal lights corresponding to the southbound and northbound entrance lanes are controlled to be green;

[0094] The third ground signal light corresponding to the southbound entrance lane and the northbound entrance lane is red.

[0095] Therefore, the embodiment of the present application controls the third ground signal light corresponding to the southbound entrance road to red light while controlling the second ground signal light and the fourth ground signal light of the southbound entrance road to green light, so that the sidewalk of the southbound entrance road can be passed in the straight lane area, reducing the waiting time for pedestrians to pass through the sidewalk and reducing the probability of pedestrians running red lights, thereby reducing safety hazards.

[0096] It is understandable that, referring to Figure 7 As shown, in the embodiment of the present application, the third ground signal light 111 corresponding to the southbound entrance road is set to be a red light, while the second ground signal light 12 and the fourth ground signal light 112 corresponding to the southbound entrance road are controlled to be green lights, so that the sidewalk of the southbound entrance road can be passed in the straight lane area. Compared with the existing technology that requires the vehicle's straight and left turn indicators to be red at the same time before passing, the waiting time of pedestrians is reduced, the probability of pedestrians running red lights is reduced, and thus safety hazards are reduced.

[0097] In some embodiments, a signal light control device includes:

[0098] a data acquisition module, configured to determine a plurality of target phases corresponding to the signal light control system, and to determine reference signal light information of a first through signal light, a first left turn signal light, and a first pedestrian signal light for different traffic directions corresponding to each target phase;

[0099] A data processing module determines target signal light information of the second through signal light, the second left turn signal light, and the second left-turn intermediate signal light corresponding to each target phase based on the reference signal light information;

[0100] The signal light control module associates the reference signal light information with the target signal light information for any target phase to obtain the target signal light instruction, and coordinately controls all ground signal lights and pole-mounted signal lights based on the target signal light instruction.
