Description

Technical Field

[0001] The present invention belongs to the technical field of urban road traffic signal control, and in particular relates to a traffic signal control method and device for controlling a non-motor vehicle waiting area. Background Art

[0002] my country's urban road traffic signal control has gone through two main stages. In the 1970s, my country's traffic signals were in the manual control stage. The traffic signal controller was a mechanical device. The traffic lights were controlled by the police in the booth turning the switch on the controller to control the switching of the traffic lights. In the 1980s, with the introduction of internationally advanced traffic signal control systems such as SCOOT and SCATS in some large cities in my country, my country's road traffic entered the stage of traffic signal control systems with coordinated control of points, lines and surfaces. By the end of 2007, the number of signal-controlled intersections in the country was about 42,000; by the end of 2022, the number of signal-controlled intersections had reached more than 300,000. At present, traffic management departments across my country are actively carrying out the construction of intelligent signal timing. In combination with actual traffic control needs, they use a variety of detection equipment such as video and radar, explore the application of cloud computing, edge computing, traffic operation big data and other methods, optimize signal control solutions, and enhance the ability to control the traffic operation of the entire city.

[0003] At present, urban road traffic signal control is mainly carried out in the following ways: 1. Stop and give way control and slow down and give way control: Both methods use specific traffic signs to control the passage of branch road vehicles through the intersection. Stop and give way control requires the driver of the branch road vehicle to stop and wait outside the stop line and confirm that it is safe before passing. This control method is mainly used in the following situations: (1) The traffic flow on the branch road is much lower than the traffic flow on the main road; (2) From the perspective of the vehicles on the branch road, the sight distance and vision are not very good; (3) The traffic flow on the main road is complex, with many lanes or many turning vehicles. Slow down and give way control requires the driver of the branch road vehicle to slow down and give way, observe the driving conditions of the main road, and continue driving only when it is considered safe on the premise of ensuring that the main road vehicles have priority. 2. Signal control: The urban traffic signal control system uses traffic lights to control the passage of vehicles and pedestrians in all directions through the intersection. 3. Traffic police command and control: In some cases, traffic police will also conduct on-site command at the intersection to control the passage of vehicles and pedestrians in all directions through the intersection.

[0004] However, the prior art still has the following defects: most cities do not have non-motor vehicle lights, and most non-motor vehicles drive according to the motor vehicle lights. In the single-phase, there will be conflicts between left-turning non-motor vehicles and motor vehicles. At the same time, there are no dedicated lanes for non-motor vehicles while non-motor vehicles are waiting at intersections, which can easily cause the outermost motor vehicle lane to be occupied, reducing lane utilization, and also posing a major safety hazard. Summary of the invention

[0005] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a traffic signal control method and device for controlling a non-motor vehicle waiting area. In view of the asymmetry or mixed lanes existing in the signal-controlled intersection, when only a single phase can be used at the intersection, a non-motor vehicle waiting area is added and an LED screen is added to guide the non-motor vehicle to enter the waiting area by pressing the light, thereby avoiding conflicts between left-turning non-motor vehicles and straight-moving motor vehicles and improving intersection safety.

[0018] When there are left-turning vehicles at the intersection that affect the release of the next phase, the counterclockwise release method is adopted.

[0019] As a preferred technical solution, the phase sequence of the intersection is redesigned as follows:

[0020] Phase 1: The west entrance is open to traffic, and non-motor vehicles entering the east and north entrances are allowed to enter the waiting area. Non-motor vehicles entering the south entrance conflict with pedestrians crossing the street on the south side and are prohibited from entering the waiting area.

[0021] Phase 2: The north entrance is open to traffic, and non-motor vehicles entering the east and south entrances are allowed to enter the waiting area. Non-motor vehicles entering the west entrance conflict with pedestrians crossing the street on the west side and are prohibited from entering the waiting area.

[0022] Phase 3: The east entrance is open to traffic, non-motor vehicles entering the south and west entrances are allowed to enter the waiting area, and non-motor vehicles entering the north entrance are prohibited from entering the waiting area because they conflict with pedestrians crossing the street;

[0023] Phase 4: The south entrance is released at a single entrance, non-motor vehicles entering the west and north entrances are allowed to enter the waiting area, and non-motor vehicles entering the east entrance conflict with pedestrians and are prohibited from entering the waiting area.

[0024] As a preferred technical solution, the device for prompting non-motor vehicles to enter the waiting area includes an LED screen and a prompt sign.

[0025] In a second aspect, the present invention provides a traffic signal control system for non-motor vehicle waiting area control, which is applied to the traffic signal control method for non-motor vehicle waiting area control, including a road intersection analysis module, a first calculation module, a first execution module, a second calculation module and a second execution module;

[0052] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0053] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0054] See also Figure 1 The present embodiment provides a traffic signal control method for controlling a non-motor vehicle waiting area, comprising the following steps:

[0055] S1. Determine whether there is a conflict between a left-turning non-motor vehicle and a straight-moving motor vehicle at the intersection. If there is a conflict, execute step S2.

[0056] like Figure 2 As shown in the figure, the intersection adopts a single-port round-robin mode for traffic, which results in serious conflicts between left-turning non-motor vehicles and straight-moving motor vehicles. Therefore, before optimizing the intersection conditions, it is necessary to collect data on the real-time conditions of the intersection to determine whether there is a conflict at the current intersection.

[0057] S2. Obtain the channelization information of the intersection, and analyze whether the channelization information of the intersection meets the conditions for setting a non-motor vehicle waiting area. If so, execute step S3.

[0058] The waiting area is an area that will not conflict with motor vehicles in other directions after the waiting area is added. Under this premise, the present embodiment sets a road intersection information channelization condition, that is, there is space to set the waiting area before the zebra crossing at the current intersection.

[0059] It needs to be explained that "before the zebra crossing" means, Figure 3 and Figure 4 As shown in FIG. 1 , on the other side of the zebra crossing relative to the intersection exit, the driving track direction is consistent with the intersection exit. If there is a right-turn channelization island next to the waiting area set at the intersection exit, then the waiting area is the most preferred, because there is sufficient space to set up the waiting area and install a prompt device. Figure 3 In the shaded area shown, the intersection meets the conditions for setting up non-motor vehicle waiting areas in four directions, and there is a right-turn channelization island on its side, which is large and is conducive to waiting for left-turn non-motor vehicles when the light is red. After completing the analysis and determination of the waiting area, the design of non-motor vehicle channelization at the intersection is executed, as shown in step S3.

[0060] S3. Redesign the non-motor vehicle channelization at intersections and add devices to remind non-motor vehicles to enter the waiting area.

[0061] According to the non-motor vehicle waiting area selected in step S2, road data from four directions of the intersection are collected, and the possibility of adding non-motor vehicle lanes is determined based on the width of each motor road at the intersection. If the width of each motor road meets the set requirements, the width of the motor vehicle lane is compressed, a non-motor vehicle lane is added, and a device is provided to prompt non-motor vehicles to enter the waiting area.

[0062] In the lane design specifications, the minimum length of a motor vehicle lane can be set at 3 meters for the entrance lane and 3.25 meters for the exit lane. Figure 4 As shown, if it is necessary to compress the width of the current road and add a non-motorized vehicle lane of 2 meters or more, and meet the lane design specifications, add an LED screen to prompt non-motorized vehicles to enter the waiting area.

[0063] LED screen prompting non-motor vehicles to enter the waiting area, such as Figure 5 The intersection meets the requirements of re-channeling the non-motor vehicle waiting area and non-motor vehicle lane. At the same time, an LED display screen is added on the right-turn channelization island (green light allows entry into the waiting area, red light prohibits entry into the waiting area), and an auxiliary sign is added (left-turning electric motorcycles please follow the signal to enter the waiting area).

[0064] S4. Calculate the clearing time of each phase of the intersection according to the conflict point of the intersection, as follows:

[0065]

[0066] Among them, S represents the intersection clearing time, L1 represents the distance from the stop line to the conflict point, L2 represents the vehicle length, and V represents the vehicle speed on the entrance road.

[0067] like Figure 6 The vehicle clearing process shown in the figure can be calculated according to the above formula to know the maximum clearing time (full red time) required for each entrance lane from entry to dissipation.

[0068] S5. Control left-turning non-motor vehicles, redesign the phase sequence of intersections, and reduce the time it takes to clear intersections.

[0069] According to the maximum clearing time calculated above, this embodiment can select the following release methods according to actual conditions, thereby reducing the clearing time (full red time):

[0070] (1) When there is a slow dissipation speed of through traffic at the intersection, which affects the release of the next phase, the clockwise release method is adopted;

[0071] (2) When there are left-turning vehicles at the intersection that affect the next phase of release, the counterclockwise release method is adopted.

[0072] Among them, Figure 7 As shown, the redesigned intersection phase sequence is as follows:

[0073] Phase 1: The west entrance is open to traffic, and non-motor vehicles entering the east and north entrances are allowed to enter the waiting area. Non-motor vehicles entering the south entrance conflict with pedestrians crossing the street on the south side and are prohibited from entering the waiting area.

[0074] Phase 2: The north entrance is open to traffic, and non-motor vehicles entering the east and south entrances are allowed to enter the waiting area. Non-motor vehicles entering the west entrance conflict with pedestrians crossing the street on the west side and are prohibited from entering the waiting area.

[0075] Phase 3: The east entrance is open to traffic, non-motor vehicles entering the south and west entrances are allowed to enter the waiting area, and non-motor vehicles entering the north entrance are prohibited from entering the waiting area because they conflict with pedestrians crossing the street;

[0076] Phase 4: The south entrance is released at a single entrance, non-motor vehicles entering the west and north entrances are allowed to enter the waiting area, and non-motor vehicles entering the east entrance conflict with pedestrians and are prohibited from entering the waiting area.

[0077] It should be noted that Figure 7 Part (a) is the solution before optimization, and part (b) is the solution after optimization. Part (b) uses solid and dashed boxes to represent the waiting area. The solid box represents "green light allows entry into the waiting area", and the dashed box represents "red light prohibits entry into the waiting area".

[0078] By adjusting the release method of the intersection, according to the optimized release method, the clearing time for each phase is 3s.

[0079] Table 1

[0080]

[0081] The data comparison before and after the intersection phase optimization is shown in Table 1. After optimization, the conflict between left-turning non-motor vehicles and straight-moving motor vehicles in the single-release phase of the intersection was solved, the traffic order and safety of the intersection were significantly improved, and the overall efficiency was also improved.

[0082] It should be noted that, for the sake of convenience, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present invention is not limited to the described order of actions, because according to the present invention, certain steps can be performed in other orders or simultaneously.

[0085] The intersection analysis module 11 is used to determine whether there is a conflict between a left-turning non-motor vehicle and a straight-moving motor vehicle at the intersection, and if there is a conflict, execute step S2;

[0086] The first calculation module 12 is used to obtain the channelization information of the intersection and analyze whether the channelization information of the intersection meets the conditions for setting the non-motor vehicle waiting area. If so, step S3 is executed;

[0087] The first execution module 13 is used to redesign the non-motor vehicle channelization at the intersection and add a device to prompt non-motor vehicles to enter the waiting area;
