Description

Technical Field

[0001] The present invention relates to the field of data processing, and in particular to a green wave disconnection method, device, equipment and medium. Background Art

[0002] Green wave is a technology that calculates the time it takes for vehicles to pass a certain section of road based on the average speed of vehicles on the road, and coordinates the traffic lights at each road intersection so that vehicles can get green lights all the way through. With the development of intelligent transportation systems, the density of urban road networks continues to increase, accompanied by a sharp increase in the number of road intersections, more and more vehicles on the road, and increasingly serious queuing and congestion. Setting up green waves can effectively utilize road resources, alleviate road congestion, and improve road traffic efficiency. However, the traffic volume on the road is constantly changing. On some green wave roads, the traffic volume at each turn at certain intersections is the same. The main direction of traffic at the intersection may change within a period of time. When the traffic flow of each turn at the intersection changes within a period of time, the main traffic direction of vehicles at the intersection will also change, that is, the original main traffic direction of vehicles is no longer the main traffic direction of vehicles at the intersection. The main traffic direction of vehicles is the main traffic direction. At this time, if the original green wave coordination direction is still maintained, it may affect the passage of vehicles in the main traffic direction of vehicles at the intersection, thereby reducing the traffic efficiency of the road. At this time, it is necessary to selectively disconnect the green waves of some road intersections in the green wave, and adjust more green signal ratios to the main traffic direction of vehicles, so as to improve the traffic efficiency of the road.

[0003] The existing green wave disconnection method is: when relevant technical personnel find that a road intersection corresponding to the green wave cannot continue to pass or the road intersection is seriously congested, the relevant technical personnel will change the relevant functions in the green wave coordination control system according to the actual situation to disconnect the green wave from the road intersection.

[0004] However, the above method also has the following technical problems:

[0005] The above method mainly relies on manual experience. There is a delay in the disconnection of the green wave, and it cannot reflect the actual changes in traffic flow in time. When the road intersections corresponding to the green wave are all passable or there is no congestion at the road intersections, the relevant personnel cannot perceive the changes in traffic flow in time and disconnect the green wave in advance. Therefore, when the traffic conditions deteriorate, it will cause a greater impact and reduce the traffic efficiency of the road. Summary of the invention

[0006] In view of the above technical problems, the technical solution adopted by the present invention is:

[0012] When the judgment mark corresponding to the road intersection mark in the preset time slice is mark "1", the preset time slice is used as the target time slice, and the road intersection corresponding to the road intersection mark corresponding to the judgment mark "1" in the preset time slice is used as the target road intersection corresponding to the target time slice, and the target green wave coordination system is ordered to issue a target instruction, so that the green wave control structure turns off the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice, wherein the mark "1" indicates that the green wave control function of the target green wave coordination system on the target road intersection in the main coordination direction of the target green wave needs to be turned off.

[0013] According to a second aspect of the present invention, a green wave disconnection device is provided, the device comprising:

[0014] The road intersection sign list acquisition module is used to obtain a road intersection sign list.

[0015] The vehicle travel direction list set acquisition module is used to obtain the vehicle travel direction list set corresponding to the road intersection identification list.

[0016] The total set acquisition module of the actual vehicle flow list set is used to acquire the total set of the actual vehicle flow list set corresponding to the vehicle travel direction list set.

[0017] The judgment mark list set acquisition module is used to obtain the judgment mark list set according to the total set of actual traffic flow list sets. The judgment mark list set includes the judgment mark lists corresponding to all preset time slices, and the judgment mark list includes the judgment marks corresponding to all road intersection marks in the preset time slice.

[0018] The green wave disconnection module is used to use the preset time slice as the target time slice, and the road intersection corresponding to the road intersection identifier corresponding to the judgment identifier "1" in the preset time slice as the target road intersection corresponding to the target time slice, and to make the target green wave coordination system issue a target instruction, so that the green wave control structure turns off the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice, wherein the identifier "1" indicates that the green wave control function of the target green wave coordination system on the target road intersection in the main coordination direction of the target green wave needs to be turned off.

[0019] According to a third aspect of the present invention, there is provided a non-transitory computer-readable storage medium, in which a computer program is stored. The computer program is loaded and executed by a processor to implement the aforementioned method.

[0020] According to a fourth aspect of the present invention, there is provided an electronic device, comprising: a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor implements the aforementioned method when executing the computer program.

[0021] The present invention has at least the following beneficial effects:

The target road intersection corresponding to the target time slice is detected and the target green wave coordination system is ordered to issue a target instruction, so that the green wave control structure closes the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice. It can be seen that the present invention can automatically realize the green wave disconnection according to the actual vehicle flow corresponding to the vehicle travel direction of the road intersection corresponding to the target green wave. There is no need to manually realize the green wave disconnection and the green wave can be disconnected in time. The green wave disconnection can enable the intersection with a large change in flow ratio to switch the main coordination direction in time and adjust the green-signal ratio, thereby improving the traffic efficiency of the road.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] Embodiment 1 of the present invention provides a green wave disconnection method, wherein the target green wave is disconnected by shutting down the green wave control function of the target green wave coordination system on the target road intersection in the main coordination direction of the target green wave, wherein the target green wave coordination system includes a traffic signal control device, wherein the traffic signal control device includes a green wave control structure, wherein the green wave control structure can shut down or start the green wave control function of the target green wave coordination system on any one road intersection corresponding to the target green wave in the main coordination direction of the target green wave, wherein the method includes the following steps: Figure 1 As shown:

[0031] S1. Obtain a list of road intersection signs, where the list of road intersection signs includes road intersection signs of several road intersections corresponding to the target green wave; that is, obtain a list of road intersection signs A={A 1 , A 2 , ..., A i , ..., A m}, where A iis the road intersection identifier of the i-th road intersection corresponding to the target green wave, the value of i ranges from 1 to m, and m is the number of road intersections corresponding to the target green wave.

[0032] Specifically, the road intersection identifier is a unique identification identifier of the road intersection.

[0033] Specifically, the target green wave coordination system is a control system for controlling the target green wave.

[0034] Specifically, green wave refers to the technology of calculating the time it takes for vehicles to pass through a certain section of road, and then coordinating the traffic lights at various road intersections so that vehicles can get green lights all the way through. It can be understood as: on a designated traffic route, after the vehicle speed of the section is specified, the traffic signal control device will make corresponding adjustments to the green light start time of each intersection passed by the traffic flow according to the distance of the section, to ensure that when the traffic flow arrives at each traffic light intersection, the traffic lights all show green lights.

[0035] Specifically, the main coordination direction of the target green wave is the vehicle travel direction selected when setting the target green wave, which enables the vehicle flow to pass through multiple road intersections continuously and obtain the best travel efficiency at the designed speed; for example, within a certain period of time, the vehicle flow in the vehicle travel direction of straight from west to east in the target green wave is relatively concentrated and stable, then it is possible to set the straight from west to east as the main coordination direction of the target green wave, that is, in this direction, the signal change time of the traffic lights at each road intersection is accurately adjusted through the target green wave coordination system to ensure that the vehicle can encounter green lights along the way to the maximum extent when traveling at the recommended speed, thereby achieving the purpose of continuously and quickly passing through the entire road section.

[0036] Specifically, the traffic signal lights at the road intersection corresponding to the target green wave are communicatively connected with the traffic signal control device in the target green wave coordination system.

[0037] S2. Obtain a set of vehicle travel direction lists corresponding to the road intersection identification list, wherein the vehicle travel direction list set includes vehicle travel direction lists corresponding to all road intersection identifications, and the vehicle travel direction list includes several vehicle travel directions corresponding to the road intersection identifications; that is, obtain a set of vehicle travel direction lists corresponding to A = {B 1 , B 2 , ..., B i , ..., B m}, B i ={B i1 , B i2 , ..., B ij , ..., B in}, where B i A i The corresponding vehicle traffic direction list, Bij A i The corresponding j-th vehicle travel direction, j takes a value from 1 to n, n is the number of vehicle travel directions corresponding to the road intersection mark, and the vehicle travel direction corresponding to the road intersection mark is the direction in which the vehicle travels through the road intersection. For example: going straight from east to west can be understood as: the vehicle enters the road intersection from the east side of the road intersection and then exits the road intersection from the west side of the road intersection; going straight from west to east can be understood as: the vehicle enters the road intersection from the west side of the road intersection and then exits the road intersection from the east side of the road intersection; turning right from east to north can be understood as: the vehicle enters the road intersection from the east side of the road intersection and then exits the road intersection from the north side of the road intersection; turning left from east to south can be understood as: the vehicle enters the road intersection from the east side of the road intersection and then exits the road intersection from the south side of the road intersection.

[0038] S3, obtaining the total set of actual vehicle flow list sets corresponding to the vehicle travel direction list set, the total set of actual vehicle flow list sets including actual vehicle flow list sets corresponding to several preset time slices, the actual vehicle flow list set including actual vehicle flow lists corresponding to all vehicle travel direction lists in the preset time slice, the actual vehicle flow list including actual vehicle flow corresponding to all vehicle travel directions in the vehicle travel direction list in the preset time slice, the actual vehicle flow equals the number of vehicles passing through the road intersection corresponding to the vehicle travel direction in the preset time slice divided by the length of the preset time slice; that is, according to B, obtaining the total set C of the actual vehicle flow list set = {C 1 , C 2 , ..., C r , ..., C s}, C r ={C r 1 , C r 2 , ..., C r i , ..., C r m}, C r i ={C r i1 , C r i2 , ..., C r ij , ..., C r in}, where C r is the actual traffic flow list set corresponding to the rth preset time slice, r ranges from 1 to s, s is the number of preset time slices, C r i B in the rth preset time slicei The corresponding actual traffic flow list, C r ij B in the rth preset time slice ij The corresponding actual traffic flow, C r ij Meet the following conditions:

[0039] C r ij =C 0r ij / t,C 0r ij For the rth preset time slice, follow B ij By A i The number of vehicles at the corresponding road intersection, t is the length of the preset time slice; for example, if the number of vehicles passing through the i-th road intersection from east to west in the r-th preset time slice is 5, and the j-th vehicle traffic direction corresponding to the i-th road intersection is marked as straight from east to west, then C 0 ij =5.

[0040] Optionally, starting from the first signal control period corresponding to the target green wave in a single time period, the signal control periods corresponding to every three target green waves are divided into a preset time slice. It can be understood that: the first, second, and third signal control periods corresponding to the target green wave in a single time period are the first preset time slice, the fourth, fifth, and sixth signal control periods corresponding to the target green wave in a single time period are the second preset time slice, and so on.

[0041] Specifically, a single time period is one day; it can be understood that the length of a single time period is 24 hours and the start time point is 00:00:00 and the end time point is 24:00:00.

[0042] Specifically, the signal control period corresponding to the target green wave is the length of time from when the traffic lights at each road intersection start turning on a green light to when the next green light turns on in the same direction on the road section corresponding to the target green wave.

[0043] Through the above steps, since the traffic flow has a certain randomness, the randomness of the traffic flow refers to the uncertainty of the number of vehicles on the road at different times and locations. Therefore, the time of a day is divided into slices according to the signal control cycle corresponding to the target green wave to obtain preset time slices, and the actual traffic flow is calculated based on every three signal control cycles as a preset time slice. This can minimize the interference of the randomness of the traffic flow and help improve the accuracy of obtaining the actual traffic flow.

[0044] S4. Obtain a judgment mark list set according to the total set of actual traffic flow list sets, wherein the judgment mark list set includes judgment mark lists corresponding to all preset time slices, and the judgment mark list includes judgment marks corresponding to all road intersection marks in the preset time slice; that is, obtain a judgment mark list set U={U 1 , U 2 , ..., U r , ..., U s},U r ={U r 1 , U r 2 , ..., U r i , ..., U r m},U r is the judgment identification list corresponding to the rth preset time slice, U r i A in the rth preset time slice i The corresponding judgment mark.

[0045] Specifically, step S4 also includes the following steps: Figure 2 As shown:

[0046] S41, obtaining a flow ratio list corresponding to the actual vehicle flow list, wherein the flow ratio list includes flow ratios corresponding to all actual vehicle flows in the actual vehicle flow list, and the flow ratio corresponding to the actual vehicle flow is equal to the actual vehicle flow divided by the sum of all actual vehicle flows in the actual vehicle flow list; that is, obtaining C r i Corresponding flow ratio table D r ij ={D r i1 , D r i2 , ..., D r ij , ..., D r in}, D r ij C r ij The corresponding flow ratio, D r ij Meet the following conditions:

[0047] D r ij =C r ij / ∑ n j=1 C r ij.

[0048] S42, according to the flow ratio list, obtain the main vehicle traffic direction of the road intersection in the preset time slice, wherein the vehicle traffic direction list corresponding to the road intersection in the preset time slice corresponds to the actual vehicle flow list corresponding to the flow ratio list corresponding to the largest flow ratio in the list as the main vehicle traffic direction of the road intersection in the preset time slice; that is, when D r ij =max(D r i1 , D r i2 , ..., D r ij , ..., D r in ),D r ij The corresponding B ij As A in the rth preset time slice i The main traffic direction of vehicles at the corresponding road intersection E r i , where max() is the maximum value acquisition function.

[0049] Specifically, when D r ij =max(D r i1 , D r i2 , ..., D r ij , ..., D r in ) can be understood as when D r ij D r i1 , D r i2 , ..., D r ij , ..., D r in When the maximum value in .

[0050] S43. When the main traffic direction of vehicles at the road intersection in the preset time slice is the same as the main coordination direction of the target green wave at the road intersection in the preset time slice, set the judgment mark corresponding to the road intersection mark in the preset time slice to mark "0", otherwise, obtain the preset flow ratio corresponding to the road intersection in the preset time slice, wherein the judgment mark includes mark "0" and mark "1", mark "0" indicates that there is no need to turn off the green wave control function of the target green wave coordination system for the target road intersection in the main coordination direction of the target green wave, and mark "1" indicates that the green wave control function of the target green wave coordination system for the target road intersection in the main coordination direction of the target green wave needs to be turned off; the judgment mark can be understood as a mark for judging whether it is necessary to turn off the green wave control function of the target green wave coordination system for the target road intersection in the main coordination direction of the target green wave; that is, when E r i With H r i If the same, set U r i To mark "0", when E r i With H r i If they are different, get F r i , F r i A in the rth preset time slice i The corresponding preset flow ratio, where H r i is the target green wave in A in the rth preset time slice i The main coordination direction in the corresponding road intersection, F r i Meet the following conditions:

[0051] F r i =F 0 / ∑ n j=1 C r ij , F 0 It is a preset traffic flow, wherein those skilled in the art know that the specific value of the preset traffic flow is set by those skilled in the art according to actual needs and will not be repeated here.

[0052] S44, according to the vehicle travel direction and the main coordination direction of the target green wave in the preset time slice at the road intersection, obtain the specified flow ratio corresponding to the road intersection in the preset time slice, wherein, when B ij With H r i If the same, ij The corresponding D rij As G r i , G r i A in the rth preset time slice i The corresponding specified flow ratio.

[0053] S45, obtaining a judgment mark corresponding to the road intersection mark in the preset time slice according to the flow ratio list, the specified flow ratio and the preset flow ratio, wherein when max(D r i1 , D r i2 , ..., D r ij , ..., D r in ) / G r i >F r i When setting U r i is marked as "1"; when max(D r i1 , D r i2 , ..., D r ij , ..., D r in ) / G r i ≤F r i When setting U r i is marked as "0".

[0054] Through the above steps, the main traffic direction of vehicles corresponding to the road intersection in the preset time slice is the traffic direction of vehicles corresponding to the maximum traffic ratio in the traffic ratio list of the actual traffic flow list corresponding to the road intersection in the preset time slice, indicating that the actual traffic flow corresponding to the main traffic direction of vehicles corresponding to the road intersection in the preset time slice is the largest actual traffic flow in the actual traffic flow list corresponding to the road intersection in the preset time slice. It can be understood that the main traffic direction of vehicles is the main traffic flow direction, and the traffic flow of the road intersection corresponding to the green wave changes in real time. With the change of traffic flow, the main traffic flow direction of the road intersection corresponding to the green wave in different preset time slices may also be different. When the main traffic flow direction of the road intersection corresponding to the green wave changes and the degree of change is large, the green wave needs to be disconnected. When the main traffic direction of vehicles corresponding to the road intersection in the preset time slice is the same as the main coordination direction of the target green wave in the preset time slice at the road intersection, it means that the main traffic flow direction of the road intersection in the preset time slice has not changed. There is no need to disconnect the green wave here, otherwise, it means that the main traffic flow direction of the road intersection in the preset time slice may have changed. At this time, the flow ratio corresponding to the main coordination direction of the target green wave in the preset time slice at the road intersection is obtained, that is, the specified flow ratio. When the ratio of the maximum flow ratio in the flow ratio list corresponding to the actual traffic flow list corresponding to the road intersection in the preset time slice to the specified flow ratio is not greater than the preset flow ratio, it means that the main traffic flow direction of the road intersection in the preset time slice has changed little, and there is no need to disconnect the green wave here. Otherwise, it means that the main traffic flow direction of the road intersection in the preset time slice has changed greatly, and the green wave needs to be disconnected here. Therefore, obtaining the judgment mark through the above steps and further realizing the green wave disconnection is conducive to improving the accuracy of the obtained judgment mark, and there is no need to manually realize the green wave disconnection and the green wave can be disconnected in time. The green wave disconnection can enable the intersection where the traffic ratio changes greatly to switch the main coordination direction in time and adjust the green signal ratio, thereby improving the traffic efficiency of the road.

[0055] S5. When the judgment mark corresponding to the road intersection mark in the preset time slice is mark "1", the preset time slice is used as the target time slice, and the road intersection corresponding to the road intersection mark corresponding to the judgment mark "1" in the preset time slice is used as the target road intersection corresponding to the target time slice, and the target green wave coordination system is instructed to issue a target instruction, so that the green wave control structure turns off the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice, and the target instruction is an instruction for the green wave control structure to turn off the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice; that is, when U r iWhen the mark is "1", U r i The corresponding preset time slice is used as the target time slice, and U r i The corresponding A i The corresponding road intersection serves as the target road intersection corresponding to the target time slice and instructs the target green wave coordination system to issue a target instruction, so that the green wave control structure closes the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice. The target instruction is an instruction for the green wave control structure to close the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice.

[0056] Specifically, when the target green wave coordination system issues the target instruction, it will also issue an associated instruction corresponding to the target instruction, so that the green wave control structure starts the green wave control function of the target green wave coordination system for the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the end time point of the target time slice, so that the green wave control function of the target green wave coordination system for the target road intersection in the main coordination direction of the target green wave is in a closed state within the target time slice corresponding to the target road intersection.

[0057] Through the above steps, the total set of actual vehicle flow list sets corresponding to the vehicle travel direction list sets is obtained, and the judgment mark list set is obtained according to the total set of actual vehicle flow list sets, the judgment mark list set includes the judgment mark lists corresponding to all preset time slices, and the judgment mark list includes the judgment marks corresponding to all road intersection marks in the preset time slice. When the judgment mark corresponding to the road intersection mark in the preset time slice is mark "1", the preset time slice is used as the target time slice, the road intersection corresponding to the road intersection mark is used as the target road intersection corresponding to the target time slice, and the target green wave coordination system is instructed to issue a target instruction, so that the green wave control structure closes the green wave control function of the target green wave coordination system on the target road intersection corresponding to the target time slice in the main coordination direction of the target green wave at the starting time point of the target time slice, and can automatically realize the green wave disconnection according to the actual vehicle flow corresponding to the vehicle travel direction of the road intersection corresponding to the target green wave, without manually realizing the green wave disconnection and can disconnect the green wave in time, and the green wave disconnection can make the intersection with a large change in flow ratio switch the main coordination direction in time, adjust the green signal ratio, thereby improving the traffic efficiency of the road.

It can be understood as: on a designated traffic route, after the vehicle speed of the section is specified, the traffic signal control device will make corresponding adjustments to the green light start time of each intersection passed by the traffic flow according to the distance of the section, to ensure that when the traffic flow arrives at each traffic light intersection, the traffic lights all show green lights.

[0064] Specifically, the main coordination direction of the target green wave is the vehicle travel direction selected when setting the target green wave, which enables the vehicle flow to pass through multiple road intersections continuously and obtain the best travel efficiency at the designed speed; for example, within a certain period of time, the vehicle flow in the vehicle travel direction of straight from west to east in the target green wave is relatively concentrated and stable, then it is possible to set the straight from west to east as the main coordination direction of the target green wave, that is, in this direction, the signal change time of the traffic lights at each road intersection is accurately adjusted through the target green wave coordination system to ensure that the vehicle can encounter green lights along the way to the maximum extent when traveling at the recommended speed, thereby achieving the purpose of continuously and quickly passing through the entire road section.

[0065] Specifically, the traffic signal lights at the road intersection corresponding to the target green wave are communicatively connected with the traffic signal control device in the target green wave coordination system.
