[0017] The embodiment of the present invention provides a data processing system for enabling a dedicated lane, the system comprising: a key road section list A = {A1, A2, ..., A i , ..., A m}、A corresponding lane indicator screen list B={B1,B2,……,B i , ..., B m}, a processor and a memory storing a computer program, wherein A i is the i-th key section, B i A i The corresponding lane indicator screen, i = 1, 2, ..., m, m is the number of key sections, and the key section is any section in a plurality of key paths from the first target location to the second target location where the historical traffic flow meets the preset traffic flow threshold. When the computer program is executed by the processor, the following steps are implemented, such as Figure 1 As shown:

[0018] S100, when A i The corresponding real-time vehicle average speed is lower than A i The corresponding preset critical average speed, and there is a target vehicle in A within the preset time. i When passing through A i The first dedicated lane is activated and the activated first dedicated lane is displayed in A i In the corresponding lane indicator screen, it can be understood that if the preset dedicated lane is already enabled at this time, the enabled state of the preset dedicated lane will be maintained.

[0019] Specifically, the lane indicator screen refers to an LED electronic indicator screen pre-set for each key section; for example: based on the direction from the first target location to the second target location, a corresponding lane indicator screen is set at the starting point of each key section, and can also be set on a traffic light frame, and multiple lane indicator screens can also be set on one side of each key section.

[0020] Specifically, the LED electronic indicator screen refers to an indicator screen used to display several lanes of the corresponding key section, and to indicate whether vehicles and personnel can pass through the preset special lanes in the key section; for example: the LED electronic indicator screen displays "Specially for target vehicles in this period" or "Social vehicles are allowed to be borrowed in this period" at the corresponding preset special lane, and switches between the two modes according to the conditions, wherein the target vehicle refers to the vehicle used by the personnel participating in this meeting or this event when going to the second target location.

[0021] Specifically, the preset dedicated lane refers to a lane that is pre-set according to the instructions of the lane indicator screen and is only used for the target vehicle to travel when enabled.

[0022] Specifically, the first dedicated lane refers to a lane that is pre-set according to the indication of the lane indication screen, is enabled with first priority, and is only used for the target vehicle to travel when enabled.

[0023] The first target location is a preset starting point, and the second target location is a preset end point; it can be understood that: when holding a competition event or a large-scale conference, the preset starting point refers to the residence of the participants of the event or conference, and the preset end point is the competition venue or conference place.

[0024] Specifically, several key paths from the first target location to the second target location are obtained through the road network matching model and the A-star algorithm, and the key paths refer to several paths that can be used for travel from the first target location to the second target location; those skilled in the art are aware of the specific implementation methods of the road network matching model and the A-star algorithm, which will not be repeated here.

[0025] In a specific embodiment, A is determined by the following specific steps: i :

[0026] S1, obtain a first section list set C corresponding to a number of key paths = {C1, C2, ..., C j , ..., C n}, C j ={C j1 , C j2 , ..., C jp , ..., C jq(j)}, where C jp is the pth first section corresponding to the jth critical path, j=1, 2, ..., n, n is the number of critical paths, p=1, 2, ..., q(j), q(j) is the number of first sections corresponding to the jth critical path.

[0027] Specifically, the first road section is any road section in any key path; wherein a road section can be understood as: a road section is between an intersection and the nearest intersection.

[0028] S2, according to C and C j , perform deduplication processing on all first road sections, and obtain the second road section list D = {D1, D2, ..., D e , ..., D f}, where D e is the e-th second section, e=1, 2, ..., f; f is the number of second sections.

[0029] Specifically, the second road section refers to any remaining first road section obtained after deduplication processing is performed on all first road sections; for example: there are two key paths in total, the first key path consists of section one, section two and section five, and the second key path consists of section three, section four and section five. When deduplication processing is performed, one of the sections five is deleted, and the second road section list obtained consists of section one, section two, section three, section four and section five.

[0030] S3, get D e The corresponding traffic flow R in the preset historical time period e ; For example: the preset historical time period can be the past seven days before the event starts.

[0031] S4, when R e ≥R0, R e Confirmed as A i , where R0 is a preset traffic flow threshold; for example, the preset traffic flow threshold may be set based on statistical historical traffic flow data.

[0032] As mentioned above, by performing road section screening, a list of all non-repetitive key road sections containing several paths can be obtained, so as to count the historical traffic flow of each key road section, making the traffic flow statistics of each key road section more accurate, so as to screen out the road sections with a traffic flow not less than a preset traffic flow threshold, and provide a basis for the installation position of the lane indicator screen.

[0033] In a specific embodiment, in S100, the following steps are performed to determine whether there is a target vehicle in A within a preset time period: i Access:

[0034] S101, according to the pre-collected target vehicle identification corresponding to each target vehicle and the pre-travel path corresponding to each target vehicle identification, a plurality of first vehicle identifications are obtained; the first vehicle identification refers to the vehicle identification included in the pre-travel path. i The target vehicle identifier corresponding to the target vehicle.

[0035] Specifically, the target vehicle identifier is a unique identifier corresponding to the target vehicle: for example, a license plate number.

[0036] S102, obtaining position information of the first vehicle corresponding to each first vehicle identification in real time.

[0037] Specifically, the position information of the first vehicle includes the position and direction of the first vehicle; for example: the position can be obtained through a GPS chip and a satellite, and the movement state and direction of the vehicle can be obtained through sensors such as an accelerometer and a gyroscope; the method for obtaining the vehicle position and direction is existing technology and will not be repeated here.

[0038] S103, according to the position information of each first vehicle, a second vehicle identification list K={K1, K2, . . . , K g , ..., K h}, where K g is the g-th second vehicle identification, g=1, 2, ..., h, h is the number of second vehicle identifications, and the second vehicle identification refers to the vehicle that has not yet been in A i The first vehicle identifier corresponding to the first vehicle traveling on A can be understood as: in the process of traveling from the first target location to the second target location, i The first vehicle on the vehicle serves as the second vehicle.

[0039] S104, according to K g The corresponding position information of the second vehicle and the data information of the map server are obtained to obtain K g The corresponding second vehicle arrives at A i The target duration T of the starting point gi ; It can be understood as: K is predicted by the map server g The corresponding second vehicle arrives at A i The target duration of the starting point, where A i The starting point is when traveling from the first target location to the second target location at A i The starting point of the travel; those skilled in the art know the specific method of predicting the time it takes for a vehicle to reach a certain location based on the vehicle's location information and the map server, which will not be repeated here.

[0040] S105, when there is at least one T gi ≤T0, it is determined that there is a target vehicle in A within the preset time. i Where T0 is the preset duration, for example, ten minutes.

[0041] As mentioned above, by obtaining the second vehicle that has not yet reached a certain key section and the position information of the second vehicle, the driving distance of the second vehicle to the key section can be calculated, and the time to reach the key section can be predicted, so as to predict whether there is a target vehicle traveling on the key section within a preset time period, and dynamically adjust the state of the preset dedicated lane according to the prediction result, so as to reasonably plan the travel of the second vehicle and social vehicles.

[0042] In another specific embodiment, the system is further used to implement the following steps:

[0043] S11, according to T0, obtain the third vehicle identification list K from K 0 ={K 0 1. K 0 2, ..., K 0 α , ..., K 0 β}, where K 0 α is the αth third vehicle identification, α=1, 2, ..., β, β is the number of third vehicle identifications, and the third vehicle identification refers to the second vehicle identification corresponding to any target duration not greater than T0; it can be understood as: obtaining the second vehicle identification whose target duration meets the requirements from the h target durations corresponding to K.

[0044] S12, when β ≥ ζ, determine that there are at least a target number of target vehicles in A within the preset time. i The above is passed, where ζ is the target number.

[0045] Specifically, A i The corresponding preset key average speed is based on A i The corresponding historical average vehicle speed or A i The corresponding road types are pre-set; for example, the main roads in the urban area are divided into low-grade sections, and the elevated expressways are divided into high-grade sections.

[0046] In a specific embodiment, S100 also includes the following steps to determine A i The corresponding preset key average speed is:

[0047] S111, when A i When the road section is the preset first type, the first key average speed is obtained and the first key average speed is determined as A i The corresponding preset key average speed.

[0048] Specifically, the first type of road section refers to a low-grade road section pre-classified by technicians in this field according to the road grade; for example, the main roads in the urban area are classified as first-type road sections; it can be understood that the first-type road section is a low-speed road section.

[0049] Specifically, the first key average speed meets the following conditions:

[0050] V1=V 0 1×θ1, where V1 is the first critical average speed, V 0 1 is the historical average vehicle speed corresponding to the first type of road section, and θ1 is a preset first proportional value.

[0051] Furthermore, the value range of θ1 is 0.75-0.85; by setting the first proportional value within this range, the first key average speed is smaller than the historical vehicle average speed corresponding to the first type of road section and is at a reasonable value, that is, when the real-time vehicle average speed drops to a certain threshold, the road section is considered to be blocked, so as to cope with the situation where the real-time vehicle average speed changes slightly due to uneven vehicle speeds, thereby improving the rationality of road condition judgment.

[0052] S112, when A i When the road section is the preset second type, the second key average speed is obtained and the second key average speed is determined as A i The corresponding preset key average speed; the second type of road section and the first type of road section are two types of road sections divided according to road types.

[0053] Specifically, the second type of road section refers to a high-grade road section pre-classified by technical personnel in this field according to the road grade; for example, an elevated expressway is classified as a second type of road section; it can be understood that the second type of road section is a high-speed road section.

[0054] Specifically, the second key average speed meets the following conditions:

[0055] V2=V 0 2×θ2, where V2 is the second critical average speed, V 0 2 is the historical average vehicle speed corresponding to the second type of road section, and θ2 is a preset second proportional value.

[0056] Furthermore, the value range of θ2 is 0.8-0.9; by fine-tuning the value range upward based on θ1, it can cope with the situation that the second type of road sections are generally longer and have more vehicles, which will cause the real-time vehicle average speed to decrease more slowly. Therefore, when the real-time vehicle average speed is lower than the second critical average speed, it is considered that congestion occurs in the section, thereby improving the rationality of road condition judgment.

[0057] The following examples are used as illustration:

[0058] A i After cleaning, screening and analyzing the historical vehicle speeds in the city (for example, Hangzhou), the historical average speed on the main roads is 31.16km / h, and the historical average speed on the elevated expressways is 57.17km / h.

[0059] If A i For ground roads, when A i When the corresponding real-time average vehicle speed is less than 25km / h and there will be a race vehicle passing on the road within 10 minutes, A is activated. i The corresponding dedicated lane; when the average speed is not less than 25km / h, and there are more than 15 race vehicles passing through the road within 10 minutes, A lane is activated. i The corresponding dedicated lane.

[0060] If A i For elevated expressway, when A i When the corresponding real-time average vehicle speed is less than 50km / h and there will be a race vehicle passing on the road within 10 minutes, A is activated. i The corresponding dedicated lane; when the average speed is not less than 50km / h, and there are more than 15 race vehicles passing through the road within 10 minutes, A lane is activated. i The corresponding dedicated lane.

[0061] In addition, when a racing vehicle encounters an emergency, several dedicated lanes that the racing vehicle is to pass through are opened in real time according to the request for opening dedicated lanes sent by the racing vehicle.

[0062] S200, every preset period, obtain the preset time length within A i The target fleet list W corresponding to all target vehicles passing through is W = {W1, W2, ..., W u , ..., W s}, where W u is the u-th target fleet, u = 1, 2, ..., s, s is the number of target fleets.

[0063] Specifically, the target vehicle fleet refers to a pre-collected vehicle fleet including one target vehicle or multiple target vehicles.

[0064] As mentioned above, as the position of the target vehicle moves, the number of target vehicles passing through the key section will change at any time. Therefore, the target fleet list needs to be updated every preset period to improve the accuracy of target fleet acquisition and the time overlap of each target fleet.

[0065] S300, when W is an empty set, in A i Close the first dedicated lane and display the status of the first dedicated lane in A i The corresponding lane indicator screen.

[0066] As mentioned above, when the target fleet list is an empty set, it indicates that there is no target vehicle traveling on the key road section, so the first dedicated lane is closed and updated to a common lane, so that social vehicles can enter the lane to drive, thereby improving the utilization rate of road resources.

[0067] S400, when W is not an empty set, obtain the time information list W corresponding to W 0 = {W 0 1.W 0 2, ..., W 0 u , ..., W 0 s},W 0 u = {W 0 u1 , W 0 u2},W 0 u1 To obtain W u The first vehicle in the i The starting time, W 0 u2 To obtain W u The last vehicle in A leaves i The starting time.

[0068] S500, according to W 0 , get W 0 The corresponding total overlap time δ w .

[0069] Specifically, δ w Meet the following conditions:

[0070] δ w =∑ s u＝1 (∑ u-1 z＝1 δ z ), where δ z is the overlapping time between the u-th target convoy and the z-th target convoy.

[0071] S600, when δ w >δ0, at A i The second lane is activated and the activated second lane is displayed in A i In the corresponding lane indication screen, δ0 is the preset overlap time threshold; it can be understood that: the enabled second dedicated lane is displayed together with the first dedicated lane on A i The corresponding lane indicator screen.

[0072] Specifically, the second dedicated lane refers to a lane that is pre-set according to the instructions of the lane indicator screen, is enabled with second priority and is only used for target vehicles to travel when enabled; it can be understood that the activation priority of the second dedicated lane is lower than the activation priority of the first dedicated lane.

[0073] As described above, by obtaining the target convoys that will pass through a certain key road section within a preset time period every preset period, the total overlapping time of several target convoys is determined to predict the degree of congestion that will occur on the key road section. When the total overlapping time is relatively long, the second dedicated lane is opened on the basis of opening the first dedicated lane to alleviate the congestion of the target vehicles and ensure that the target vehicles can arrive at the corresponding locations safely and on time.

[0074] In a specific embodiment, the method further comprises the following steps:

[0075] S10, obtaining a log report for each day within a preset number of days; the log report includes B i The corresponding preset number of special lane adjustments, B i The corresponding preset dedicated lane utilization rate λ i and the average activation time ε of the preset dedicated lane.

[0076] Specifically, within the day B i The corresponding preset number of special lane adjustments refers to the number of B i The number of times the preset dedicated lane is enabled and closed can be understood as: i An operation that both activates and closes a preset dedicated lane will be recorded as one regulation. If there is only a record of activation or closure, that operation will be ignored and not counted as the number of regulations.

[0077] Specifically, i Meet the following conditions:

[0078] λ i =(L i ×T i ) / (∑ m i＝1 L i ×24), where L i For B i The length of the corresponding preset dedicated lane, T i For B i The corresponding preset dedicated lane is activated at that time of the day.

[0079] Specifically, ε meets the following conditions:

[0080] ε=(∑ m i＝1 T i) / φ, where φ is the number of preset dedicated lanes activated on that day.

[0081] S20, uploading and storing the log report into a target database.

[0082] As mentioned above, by collecting statistics on the usage of the preset dedicated lanes every day during the event and uploading them to the platform's database, the platform can record all operation logs of the lane indicator screen, ensure the safe operation of the lane indicator screen during the event or meeting, and enable the staff to conduct statistical analysis on the recorded relevant data later.

[0083] In summary, the present invention provides a data processing system for enabling a dedicated lane. When the computer program is executed by the processor, when the real-time average vehicle speed corresponding to the key section is lower than the preset critical average speed corresponding to the key section, and there is a target vehicle passing through the key section within a preset time, the first dedicated lane is enabled in the key section and the enabled first dedicated lane is displayed in the lane indicator screen corresponding to the key section, and then every preset period, the target fleet list corresponding to the target vehicle that will pass through the key section within the preset time is obtained, when there is no target fleet, the first dedicated lane is closed, when there is a target fleet, the time information of each existing target fleet is obtained, and the second dedicated lane in the key section is enabled according to the calculated total overlap time. Through the above steps, the present invention can realize the dynamic activation of the dedicated lane according to the actual road conditions and the time overlap information of the fleet, and display it in the lane indicator screen, so that the travelers can understand the traffic conditions in time, ensure that the dedicated vehicles have priority to pass and arrive safely and on time, and also realize the reasonable planning of the travel of the dedicated vehicles and the social vehicles, and improve the utilization rate of the road resources.

It will also be appreciated by those skilled in the art that various modifications may be made to the embodiments without departing from the scope and spirit of the present invention.
