Abstract
Description
Technical Field
[0001] The present application relates to the technical field of traffic equipment and road markings, and in particular to a traffic signal light system and a control method. Background Art
[0002] A major feature of urban road traffic is the large number of intersections, where vehicles need to frequently stop and wait for clearance, and road intersections have become a bottleneck for urban traffic. At present, at intersections controlled by traffic lights, vehicles need to stop at the entrance stop line of the intersection and wait for the traffic light of that phase to be released before passing through the intersection in turn. It takes a while for vehicles at the intersection to go from the parking state to the start and then to the normal driving stage. Generally speaking, for at least 5 seconds after the green light is released, the intersection is basically in an inefficient operating state, that is, the transition state from parking to normal driving of vehicles. This process seriously affects the traffic volume of vehicles at the intersection.
[0003] In order to improve the traffic efficiency of vehicles at road intersections, the national standard GB 51038-2015 "Specifications for the Setting of Traffic Signs and Markings on Urban Roads" stipulates: If the intersection is large and there are many left-turning vehicles, left-turning vehicles enter the waiting area to wait for left turns during the straight-ahead period, and a left-turn waiting area line should be set. If the intersection is large and there are many straight-ahead lanes and vehicles, straight-ahead vehicles enter the waiting area to wait for straight-ahead when turning left on the transverse road, and a straight-ahead waiting area line should be set. By setting up left-turn waiting areas and straight-ahead waiting areas, the travel distance of vehicles during the signal release period of this phase is shortened, thereby shortening the travel time, increasing the number of vehicles passing per unit time, and thus improving the traffic efficiency of vehicles at road intersections.
[0004] However, although the left-turn waiting area and the straight-ahead waiting area are set up, in practice there are still motor vehicle drivers who do not understand the usage rules of the left-turn waiting area and the straight-ahead waiting area, or are unsure whether they can enter the left-turn waiting area and the straight-ahead waiting area, thus failing to fully utilize the vehicle passage function of the left-turn waiting area and the straight-ahead waiting area.
[0005] Therefore, in the prior art, a signboard is generally added next to the traffic light, and auxiliary text is displayed on the signboard to provide prompts for the left turn signal and the straight go signal. The signboard needs to be installed on the mounting frame for installing the indicator light, which increases the load-bearing capacity of the mounting frame and shortens the service life of the traffic light system.

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are 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 also fall within the scope of protection of the present application.
[0024] In the prior art, in order to improve the traffic efficiency at road intersections, left-turn waiting areas and straight-ahead waiting areas are set at road intersections so that vehicles can enter the left-turn waiting areas and straight-ahead waiting areas in advance, thereby shortening the travel time.
[0025] However, although the left-turn waiting area and the straight-ahead waiting area have been set up, in practice there are still motor vehicle drivers who do not understand the usage rules of the left-turn waiting area and the straight-ahead waiting area, or are unsure whether they can enter the left-turn waiting area and the straight-ahead waiting area, thus failing to fully utilize the vehicle passage function of the left-turn waiting area and the straight-ahead waiting area.
[0026] Therefore, in the prior art, a signboard is generally added next to the traffic light, and auxiliary text is displayed on the signboard to provide prompts for the left turn signal and the straight go signal. When installing the signboard, it is necessary to install it on the mounting frame for mounting the indicator light, which increases the load-bearing capacity of the mounting frame and shortens the service life of the traffic light system.
[0027] Therefore, in order to solve the technical problems in the above-mentioned prior art, the present application proposes a traffic light system and a control method. On the basis of the existing traffic light system, the colors and shapes of the signal lights in the straight signal light group and the left turn signal light group when they are on are rearranged and displayed, so as to intuitively guide vehicles into the left turn waiting area and the straight waiting area. There is no need to add or replace new signal lights, nor is there any need to install signboards on the mounting frame. The impact on the service life of the traffic light system is extremely small, and it is easy to implement, thereby contributing to popularization and application. In addition, the color and shape of the signal lights when they are on remind the driver, which helps the driver understand the meaning of the signal lights, thereby driving the vehicle into the left turn waiting area and the straight waiting area, thereby improving the traffic efficiency of road intersections.
[0028] Figure 1 A combined schematic diagram of a traffic light system indicating a left turn is provided in an embodiment of the present application. Figure 2 A combined schematic diagram of a traffic light system indicating going straight or waiting for going provided in an embodiment of the present application, Figure 3 A schematic diagram of a road intersection where a traffic light system indicates a left turn is provided in an embodiment of the present application. Figure 4 A schematic diagram of a road intersection indicating straight ahead or waiting for travel by a traffic light system provided in an embodiment of the present application.
[0029] like Figure 1-Figure 4 As shown, the traffic signal light system includes: a straight signal light group, a left turn signal light group and a mounting frame, the straight signal light group includes: a straight forbidden signal light, a straight waiting signal light and a straight passing signal light, the left turn signal light group includes: a left turn forbidden signal light, a left turn waiting signal light and a left turn passing signal light, and the straight signal light group and the left turn signal light group are installed on the mounting frame; like Figure 1As shown, when the straight-through signal light corresponding to the direction is on, the left-turn waiting signal light corresponding to the direction is switched to the left-turn waiting signal light, so that the left-turn waiting signal light displays the first mark 100, and the first mark 100 is used to indicate that the left-turning vehicle corresponding to the direction enters the left-turn waiting area 300; like Figure 2 As shown, when the left turn signal light corresponding to the transverse road is on, the straight waiting signal light corresponding to this direction is switched to the straight waiting signal light, so that the straight waiting signal light displays the second mark 200, and the second mark 200 is used to indicate that the straight vehicles corresponding to this direction enter the straight waiting area 400.
[0030] In this embodiment, the direction refers to that the straight-moving vehicle and the left-turning vehicle are located in the same direction, for example, the straight-moving vehicle and the left-turning vehicle are both located on the road in the east-west direction.
[0031] The transverse road is relative to the current direction. For example, the vehicle going straight is on the road in the east-west direction, and the vehicle turning left is on the road in the north-south direction.
[0032] like Figure 1 and Figure 3 As shown, Figure 1 The left side shows a state diagram of the traffic light system when it is not in use, and the right side shows a state diagram of the traffic light system indicating a left turn is pending.
[0033] like Figure 2 and Figure 4 As shown, Figure 2 The left side shows the status diagram when the traffic light system is not in use, the upper right side shows the status diagram of the left-turn traffic light corresponding to the transverse road indicating a left turn, and the lower right side shows the status diagram of the traffic light system in this direction indicating going straight.
[0034] Among them, the no-going-straight signal light, the straight-waiting signal light and the straight-through signal light are used to display the colors of the three signal lights, red, yellow and green, respectively. When the no-going-straight signal light is on and shows red, the straight-waiting signal light and the straight-through signal light are off, indicating that straight-going vehicles are prohibited from passing at this time; when the straight-waiting signal light is on and shows yellow, the no-going-straight signal light and the straight-through signal light are off, indicating that straight-going vehicles are waiting to pass at this time; when the straight-through signal light is on and shows green, the no-going-straight signal light and the straight-waiting signal light are off, indicating that straight-going vehicles can pass at this time.
[0035] The left-turn prohibited signal light, the left-turn waiting signal light and the left-turn passing signal light are used to display the colors of red, yellow and green signal lights respectively. When the left-turn prohibited signal light is red, the left-turn waiting signal light and the left-turn passing signal light are off, indicating that left-turning vehicles are prohibited from passing at this time; when the left-turn waiting signal light is yellow, the left-turn prohibited signal light and the left-turn passing signal light are off, indicating that left-turning vehicles are waiting to pass at this time; when the left-turn passing signal light is green, the left-turn prohibited signal light and the left-turn waiting signal light are off, indicating that left-turning vehicles can pass at this time.
[0036] On this basis, if Figure 1 and Figure 3 As shown, when the straight-through traffic signal light is on and displays green, the left-turn waiting signal light in this direction is switched to the left-turn waiting signal light, wherein the display of the left-turn waiting signal light is different from the left-turn waiting signal light being on and displaying yellow, and is also different from the left-turn prohibited signal light being on and displaying red and the left-turn traffic signal light being on and displaying green. The left-turn waiting signal light displays a first mark 100, which is distinguished from the left-turn waiting signal light being on and displaying yellow to indicate that the left-turning vehicle in this direction enters the left-turn waiting area. For example, the first mark 100 may be an exclamation mark "!", or the first mark 100 may be a triangle, wherein the exclamation mark "!" and the triangle are formed by turning on and off the light-emitting units at different positions in the left-turn waiting signal light, and the light-emitting units corresponding to the exclamation mark "!" and the triangle are in an on state.
[0037] Similarly, if Figure 2 and Figure 4 As shown, when the left turn signal light corresponding to the transverse lane is green, the straight waiting signal light in this direction is switched to the straight waiting signal light. The straight waiting signal light is different from the straight waiting signal light being yellow, the straight forbidden signal light being red, and the straight pass signal light being green. The straight waiting signal light displays a second mark 200, which may be the same as or different from the first mark 100, to indicate that the straight vehicles in this direction enter the straight waiting area.
[0038] In this embodiment, when the straight-through traffic signal light corresponding to the direction is on, the left-turn waiting signal light corresponding to the direction is switched to the left-turn waiting signal light, and the left-turn waiting signal light displays a first mark 100, and the first mark 100 is used to indicate that the left-turning vehicles corresponding to the direction enter the left-turn waiting area; when the left-turn traffic signal light corresponding to the transverse road is on, the straight-through waiting signal light corresponding to the direction is switched to the straight-through waiting signal light, and the straight-through waiting signal light displays a second mark 200, and the second mark 200 is used to indicate that the straight-through vehicles corresponding to the direction enter the straight-through waiting area. On the basis of the existing traffic signal light system, the display function of the left turn waiting signal light and the straight going waiting signal light is added to indicate left-turning vehicles to enter the left turn waiting area and straight going vehicles to enter the straight going waiting area. There is no need to add or replace new signal lights, nor is there any need to install signboards on the mounting frame. It has little impact on the service life of the traffic signal light system and is easy to implement, which is helpful for promotion and application. It also serves as a reminder for drivers, helping them to understand the meaning of the signal lights, so that they can drive the vehicles into the left turn waiting area and the straight going waiting area, thereby improving the traffic efficiency of road intersections.
[0039] Figure 5-Figure 12 They are combined schematic diagrams of the traffic light system indicating left turn and waiting for turn provided in this application. Figure 13-Figure 20 They are combined schematic diagrams of the traffic signal light system provided in this application indicating going straight or waiting. Figure 9-12 In the figure, the upper part shows the state diagram of the traffic light system when it is not in use, and the lower part shows the state diagram of the traffic light system when it indicates that a left turn is pending. Figure 17-Figure 20 In the figure, the upper part shows the state diagram when the traffic light system is not in use, the middle part shows the state diagram when the left-turn traffic light corresponding to the transverse road indicates left turn, and the lower part shows the state diagram when the traffic light system in this direction indicates going straight and waiting.
[0040] like Figure 1-Figure 20 As shown in the figure, the straight-ahead prohibited signal light, the straight-ahead waiting signal light and the straight-ahead passing signal light can be represented by an upward arrow, and the left-turn prohibited signal light, the left-turn waiting signal light and the left-turn passing signal light can be represented by an arrow pointing to the left. Alternatively, the straight-ahead prohibited signal light, the straight-ahead waiting signal light and the straight-ahead passing signal light are represented by a circle, and the left-turn prohibited signal light, the left-turn waiting signal light and the left-turn passing signal light are represented by an arrow pointing to the left.
[0041] It should also be noted that if Figure 1-Figure 20 As shown, the straight-ahead no-go signal light, the straight-ahead waiting signal light and the straight-ahead passing signal light, as well as the left-turn no-go signal light, the left-turn waiting signal light and the left-turn passing signal light can be arranged vertically, or the straight-ahead no-go signal light, the straight-ahead waiting signal light and the straight-ahead passing signal light, as well as the left-turn no-go signal light, the left-turn waiting signal light and the left-turn passing signal light can be arranged horizontally.
[0042] It should also be noted that if Figure 1-Figure 20 As shown, the number of straight signal light groups corresponds to the number of straight lanes, and the number of left turn signal light groups corresponds to the number of left turn lanes. For example, when there are two lanes in one direction, the left lane is used for left turn, which corresponds to the left turn signal light group, and the right lane is used for straight and right turn, which corresponds to the straight signal light group.
[0043] It should also be noted that if Figure 1-Figure 20 As shown, the traffic light system may also include a right turn signal light group, which controls the passage of right-turn vehicles by setting a right turn no-go signal light, a right turn wait signal light and a right turn pass signal light.
[0044] Optional, such as Figure 5-Figure 12 As shown, the first identification 100 includes: a first red display area 110 and a first green display area 120. The first red display area 110 and the first green display area 120 are combined to overlap with the display area of the left-turn waiting signal light.
[0045] Specifically, when the left turn waiting signal light is on, a circle is displayed, that is, the first mark 100 is a circle, which is divided into a first red display area 110 and a first green display area 120, that is, when the left turn waiting signal light is on, red and green lights are displayed at the same time. Among them, the red color of the left turn waiting signal light and the red color of the left turn prohibited signal light can remind the driver that left turn is prohibited at this time, and the green color of the left turn waiting signal light is used to remind the driver that it is possible to go forward and enter the left turn waiting area to wait. In addition, the first mark 100 is designed to include two colors, which can better attract the driver's attention, so that the driver sees that the left turn waiting signal light is on, thereby playing a good reminder role.
[0046] Optional, such as Figure 5-Figure 12 As shown, the area of the first red display region 110 is greater than the area of the first green display region 120 .
[0047] Specifically, the area of the first red display area 110 is designed to be larger than the area of the first green display area 120. In this way, when the left turn signal light is on, a visual conflict is formed, thereby attracting the driver's attention, so that the driver can quickly see the left turn signal light.
[0048] Optional, such as Figure 5-Figure 12 As shown, the line segment corresponding to the connection between the first red display area 110 and the first green display area is tilted, and the tilt direction points to the left.
[0049] Specifically, the connection between the first red display area 110 and the first green display area 120 is a line segment, and the line segment is inclined by setting the positional relationship between the first red display area 110 and the first green display area 120, wherein the left-turn waiting signal light is used to remind the driver to enter the left-turn waiting area. Therefore, the line segment is a line segment from the lower left to the upper right. In this way, when the driver sees the left-turn waiting signal light, the driver can be guided to enter the left-turn waiting area.
[0050] Optional, such as Figure 5-Figure 12 As shown, the first red display area 110 is always on, and the first green display area 120 flashes.
[0051] Specifically, by controlling the light-emitting units corresponding to the first red display area 110 and the first green display area 120, the first red display area 110 is always on and the first green display area 120 flashes, further forming a visual conflict, reminding the driver that it is time to enter the left turn waiting area.
[0052] Optional, such as Figure 13-Figure 20 As shown, the second identification 200 includes: a second red display area 210 and a second green display area 220. The second red display area 210 and the second green display area 220 are combined to overlap with the display area of the straight waiting signal light.
[0053] Specifically, when the straight waiting signal light is on, it is displayed as a circle, that is, the second mark 200 is a circle, which is divided into a second red display area 210 and a second green display area 220, that is, when the straight waiting signal light is on, it displays red and green at the same time. Among them, the straight waiting signal light displays red and the straight forbidden signal light displays red together to remind the driver that straight driving is prohibited at this time, and the straight waiting signal light displays green to remind the driver that it is possible to go forward and enter the straight waiting area to wait. In addition, the second mark 200 is designed to include two colors, which can better attract the driver's attention, so that the driver sees that the left turn waiting signal light is on, thereby playing a good reminder role.
[0054] Optional, such as Figure 13-Figure 20 As shown, the area of the second red display region 210 is greater than the area of the second green display region 220 .
[0055] Specifically, the area of the second red display area 210 is designed to be larger than the area of the second green display area 220. In this way, when the straight-ahead signal light is on, a visual conflict is formed, thereby attracting the driver's attention, so that the driver can quickly see the left-turn signal light.
[0056] Optional, such as Figure 13-Figure 20As shown, the line segment corresponding to the connection between the second red display area 210 and the second green display area 220 is set horizontally.
[0057] Specifically, the connection between the second red display area 210 and the second green display area 220 is a line segment, and the direction of the line segment is controlled by setting the positional relationship between the second red display area 210 and the second green display area 220. The straight-ahead waiting signal light is used to remind the driver to enter the straight-ahead waiting area, so the line segment is set horizontally, so that when the driver sees the straight-ahead waiting signal light, the driver can be guided to enter the straight-ahead waiting area. In addition, by setting the line segment at the connection between the second red display area 210 and the second green display area 220 horizontally, it is also distinguished from the line segment corresponding to the connection between the first red display area 110 and the first green display area 120 to avoid confusion for the driver.
[0058] Optional, such as Figure 13-Figure 20 As shown, the second red display area 210 is always on, and the second green display area 220 flashes.
[0059] Specifically, by controlling the light-emitting units corresponding to the second red display area 210 and the second green display area 220, the second red display area 210 is always on and the second green display area 220 flashes, further forming a visual conflict, reminding the driver that he can enter the straight-ahead waiting area at this time.

Fig.21 As shown, the execution subject of this embodiment may be a PLC controller, and the method includes: S211. When the straight traffic signal light corresponding to the current direction is on, the left turn waiting signal light corresponding to the current direction is controlled to switch to a left turn waiting signal light, so that the left turn waiting signal light displays a first mark.
[0061] Among them, the first mark is used to indicate that the left-turning vehicles corresponding to this direction enter the left-turn waiting area.
[0062] S212: When the left-turn traffic signal light corresponding to the transverse road is on, control the straight-ahead traffic signal light corresponding to the current direction to switch to a straight-ahead traffic signal light, so that the straight-ahead traffic signal light displays a second mark.
