as described above, the present inventors have found that in the conventional traffic information prompting method, traffic information is usually displayed to a passing vehicle by using a portal frame display screen disposed on a road, or is broadcast to a listening audience by using traffic broadcasting. However, the construction cost of the portal frames is high, the interval distance between two adjacent portal frames is too long, the prompt of traffic information cannot effectively cover vehicles running on all road sections, and the mode of adopting traffic broadcasting prompt is low in cost and wide in coverage, but cannot prompt information for users driving vehicles on specific road sections.
In view of the above-mentioned research findings of the inventor, embodiments of the present application provide a traffic information prompting method, apparatus, device, and computer readable storage medium, which can solve the technical problem in the prior art that it is impossible to implement comprehensive monitoring of each road section of a vehicle driving road at a lower cost, and send traffic information prompts to a target user.
The following first describes a traffic information prompting method provided by the embodiment of the present application.

Specifically, manufacturers of the geographic information system are docked in an interface mode, analysis of link data of the first road, road modeling and rendering of a base layer are completed, digital superposition of road attribute data such as kilometers piles and video bayonets in the first road base data is achieved, meanwhile, base station data of operators are coupled, and according to sectors effectively covered by base station signaling data, an association mapping table of the kilometers piles of the first road and base stations along the line is obtained, so that base station cells corresponding to different road segments on the first road are determined.
S103, according to the base station cell corresponding to the target road section, determining the user terminal which establishes connection with the base station cell corresponding to the target road section. The target road segment is a road segment of different road segments on the first road.
Specifically, according to the association mapping table of the first road kilometer pile and the base stations along the road, a plurality of base station cells corresponding to the target road section on the first road can be determined, and according to the base station data of the operator, all user terminals which are connected with the plurality of base station cells corresponding to the target road section can be determined.
S104, according to the real-time position data of the user terminal, the target user terminal meeting the preset condition is screened out from the user terminals.
Specifically, the real-time position data of the user terminal may be obtained through a positioning system such as a GPS installed on the user terminal, and the real-time position data of the user terminal may include, but is not limited to, a position, a movement rate, a movement direction, and the like of the user terminal. According to the real-time position data of the user terminal, the moving condition of the user terminal among a plurality of base station cells corresponding to the target road section can be determined, and accordingly whether the user terminal is a target user terminal meeting preset conditions, namely a service object of traffic information prompt can be judged.
And S105, when the traffic information is received, the traffic information is sent to the target user terminal so as to prompt the user of the target user terminal.
Specifically, when the command center receives the information about the first road traffic condition, the command center sends corresponding traffic information to the target user terminal to prompt the current road traffic condition of the user of the target user terminal.
According to the traffic information prompting method provided by the embodiment of the application, the target user terminal is determined based on the association relation between the base station cells covering different road sections and the user terminal, and the target user is prompted in a mode of sending traffic information to the target user terminal, so that the comprehensive monitoring of each road section of the vehicle driving road can be realized, the coverage of the information is improved, investment construction of hardware equipment is not needed, and the cost of information prompting is reduced.
In one example, selecting a target user terminal satisfying a preset condition from the user terminals according to the real-time location data of the user terminals includes: according to the real-time position data of the user terminal, determining the moving speed and moving direction of the user terminal between the base station cells corresponding to the target road section; when the moving speed is greater than a preset speed threshold, determining the user terminal as a quasi-target user terminal; and determining the target user terminal according to the quasi-target user terminal.
Specifically, according to the real-time position data of the user terminal, a plurality of different base station cells continuously connected with the user terminal when the user runs on the first road can be determined, and the moving speed and moving direction of the user terminal when the user terminal moves among the plurality of different base station cells connected with the user terminal can be determined through the real-time position data of the user terminal recorded by the positioning system. When the moving speed of the user terminal is greater than the preset speed threshold, the user of the user terminal is currently running on the first road, and the user terminal can be determined to be the quasi-target user terminal, so that the target user terminal is further screened out from the range of the quasi-target user terminal. The preset speed threshold may be set according to a specific condition of the first road, which is not limited in this embodiment.
Through the embodiment, the user currently traveling on the first road can be primarily screened according to the moving speed of the user terminal, and the analysis range of the target user terminal is reduced, so that the final target user terminal can be determined according to the quasi-target user terminal.
In one example, determining a target user terminal from a quasi-target user terminal includes: after the quasi-target user terminal establishes connection with the first base station, recording the connection duration; when the connection time length is smaller than the preset time length, determining the quasi-target user terminal as a final target user terminal; when the connection time length is longer than the preset time length, obtaining connection information of the quasi-target user terminal and the first base station in a historical time period, and determining that the quasi-target user terminal is a non-target user terminal when the connection information indicates that the connection frequency of the quasi-target user terminal and the first base station is greater than the preset connection frequency; after the quasi-target user terminal establishes connection with the first base station and does not establish connection with the base station after the moving direction, determining the quasi-target user terminal as a non-target user terminal; the first base station is any base station in base station data corresponding to the first road.
Specifically, any base station in the base station data corresponding to the first road is selected as the first base station, and the connection duration after the quasi-target user terminal is connected with the first base station is recorded. When the connection time is smaller than the preset time, the user of the quasi-target user terminal is indicated to be currently running on the first road and not stay for a long time, belongs to a service object of traffic information prompt, and is determined to be a final target user terminal. When the connection time length is longer than the preset time length, the user of the quasi-target user terminal is indicated to stay on the road section corresponding to the first base station for a long time, connection information of the quasi-target user terminal and the first base station in a historical time period needs to be further acquired at the moment, if the connection information indicates that the connection frequency of the quasi-target user terminal and the first base station is greater than the preset connection frequency, the quasi-target user terminal is indicated to stay on the road section corresponding to the first base station frequently, and the quasi-target user terminal belongs to resident users or staff under the first base station and is determined to be a non-target user terminal. If the quasi-target user terminal is connected with the first base station, the connection with the base station behind the current moving direction is not established any more, the fact that the user of the quasi-target user terminal has driven off the first road is indicated, and the quasi-target user terminal is determined to be a non-target user terminal.
Through the embodiment, the users continuously driving on the first road or only staying briefly can be further screened according to the connection time of the quasi-target user terminal and the first base station, so that the final target user terminal is determined, and finer distinction is made between the users of the non-target user terminals.
In one example, selecting a target user terminal satisfying a preset condition from the user terminals according to the real-time location data of the user terminals includes: acquiring road driving video data of a target vehicle passing through a plurality of target position points of a first road; the base station cells covering the plurality of target position points are a plurality of target base station cells; according to the road driving video data, determining the vehicle information of a target vehicle passing through each target position point at the same time, and according to the communication signaling data of the user terminal and the target base station cell, determining a first user terminal which is connected with each target base station cell at the same time; and determining the target user terminal according to the first user terminal when the target vehicle is one or only one.
Specifically, a plurality of target location points on the first road are selected, and the plurality of target location points respectively correspond to different target base station cells. And acquiring road driving video data of all target vehicles passing through the first target position point at the first time node along the driving direction of the vehicle, analyzing vehicle information of all target vehicles according to the road driving video data of the target vehicles, and determining all user terminals connected with the target base station cell covering the first target position point at the first time node according to communication signaling data of the user terminals and the target base station cell. And acquiring respective second time nodes of all the target vehicles when passing through the second target position point, wherein the second time nodes of different target vehicles may be different, and determining all user terminals which establish connection between the respective second time nodes of different target vehicles and the target base station cell covering the second target position point. This step is performed sequentially downwards until there is one and only one target vehicle passing through the same target position point at the same time node, and the user terminal determined under the time node is the first user terminal associated with the target vehicle.
The plurality of target location points of the first road may be a plurality of video clips on the first road, the cameras of the video clips may capture the passing vehicles in real time, and the collected road driving video data is analyzed in real time in a form of a message queue to obtain data such as a running speed, a driving lane, vehicle information and the like of the vehicles, and the vehicle information may include, but is not limited to, license plate numbers, vehicle colors and vehicle types.
Through the embodiment, the road driving video data is analyzed in real time, the target vehicle passing through the same target position point and the time node of the target vehicle passing through the same target position point are determined, and the first user terminal is determined from the user terminals connected with the target base station cell at the same time node, so that the association between the target vehicle and the user terminals is realized.
In one example, determining a target user terminal from a first user terminal includes: when the first user terminal is plural, any one of the plural is selected as the target user terminal.
Specifically, there may be a plurality of first user terminals associated with the same target vehicle, and when a plurality of first user terminals are present, any one of the first user terminals may be selected as the target user terminal corresponding to the target vehicle, so as to reduce the data volume of communication interaction between the target user terminal and the base station cell.
In one example, the plurality of target location points satisfy the following condition: a plurality of target base station cells covering a plurality of target position points are different base station cells; when the target vehicles are one and only one, the user terminals which are connected with the target base station cells covering the current target position point comprise first user terminals which are connected with all the target base station cells; when there is one target vehicle and only one target vehicle, the average value of the similarity between the vehicle tracks of all the target vehicles passing through the current target position point and the moving track of the first user terminal is larger than a preset average value threshold value of the similarity.
Specifically, when selecting a target location point, the target location points corresponding to different base station cells are typically sequentially selected from the starting end of the first road. When one target vehicle passes through the same target position point at the same time, the target position point is taken as the last target position point selected on the first road, when all target vehicles pass through the target position point, all first user terminals which are determined to be associated with all target vehicles comprise all user terminals of all target users which are determined to establish connection with the target base station cell corresponding to the first target position point when all target vehicles pass through the first target position point at the first time point, namely the next target position point of each selected target position point, and when all target vehicles pass through the next target position point, all user terminals of all target users which are connected with the target base station cell corresponding to the next target position point comprise all user terminals of all target users which are connected with the target base station cell corresponding to the previous target position point when all target vehicles pass through the previous target position point. When all the target vehicles pass through the last target position point, the respective vehicle track of the target vehicles and the moving track of all the first user terminals associated with each target vehicle must have a similarity average value greater than a preset similarity average value threshold, that is, the vehicle track of the same target vehicle and the moving track of the first user terminal associated with the target vehicle should have higher similarity.
Through the embodiment, the selection conditions of the target position points are set, so that the proper target position points are determined according to the selection conditions to perform relationship matching between the target vehicle and the user terminal, and the problem that when a target base station cell radiates a plurality of road sections simultaneously, the filtering matching of the human-vehicle relationship is difficult to perform due to more user terminal signaling data received at the same time, and the accuracy of relationship matching between the target vehicle and the user terminal is affected is solved.
In one example, prior to acquiring the road travel video data of the target vehicle passing through the plurality of target location points of the first road, the method further comprises: acquiring road driving video data of a target vehicle passing through a plurality of position points of a first road and real-time position data of a user terminal connected with a base station cell covering the plurality of position points; determining a vehicle track of the target vehicle and a movement track of the user terminal according to the road running video data of the target vehicle and the real-time position data of the user terminal; calculating the average value of the similarity of the vehicle track and the moving track; and determining the position point as the target position point when the average value of the similarity of each position point is larger than the average value of the similarity of the previous position point in the running direction of the target vehicle.
Specifically, a first position point is selected from the starting end of a first road, road driving video data of all target vehicles passing through the first position point is obtained through shooting of a video bayonet or recording of a vehicle-mounted system, and the road driving video data is analyzed to determine real-time position data of all the target vehicles. And acquiring the real-time position data of all the user terminals in the base station cell corresponding to the target position point through the user terminal signaling data received by the base station cell. The vehicle track of each target vehicle can be determined according to the real-time position data of all the target vehicles, and the moving track of each user terminal can be determined according to the real-time position data of all the user terminals. Because the number of the target vehicles and the number of the user terminals are different, track clustering can be firstly performed on the vehicle tracks of the target vehicles and the moving tracks of the user terminals respectively. The method comprises the steps of aggregating vehicle tracks of all target vehicles into N track paths according to track similarity to obtain a path set A, and aggregating moving tracks of all user terminals into N track paths according to track similarity to obtain a path set B; and then sequentially selecting paths in any path set and all paths in the other path set to calculate the path similarity respectively, and calculating the average value of the path similarity as the similarity average value of the first position point.
And acquiring user terminal signaling data received by the next base station cell of the base station cell corresponding to the first position point along the running direction of the target vehicle, judging whether all user terminal data in the next base station cell comprises all user terminal data in the base station cell corresponding to the first position point, if so, determining the position point corresponding to the next base station cell as the next position point of the first position point, and if not, continuing to acquire the user terminal signaling data received by the new next base station cell until all user terminal data in the new base station cell comprises all user terminal data in the base station cell corresponding to the first position point.
After determining the next position point of the first position point, calculating the average value of the similarity of the next position point again according to the steps, judging whether the average value of the similarity of the next position point is larger than the average value of the similarity of the first position point, if so, taking the first position point and the next position point as the final selected target position point to match the relationship between the subsequent target vehicle and the user terminal, and if so, taking the next position point as a new first position point, and re-executing the steps until the new next position point meeting the conditions is selected.
Through the embodiment, the target position points meeting the conditions can be automatically determined according to the road running video data of the target vehicle and the real-time position data of the user terminal, so that the situation that the road change condition cannot be flexibly adapted when the number of the target position points is small or the position is fixed is avoided, and the accurate matching between the target vehicle and the user terminal is realized.
