Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In some of the flows described in the specification and claims of this application and in the above figures, a number of operations are included that occur in a particular order, but it should be clearly understood that these operations may be performed out of order or in parallel as they occur herein, the order of the operations being 101, 102, etc. merely to distinguish between various operations, the order of which does not itself denote any order of performance. Additionally, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different.

In combination with the background art, for the reasons of traffic safety and maintaining traffic order, some types of roads set road driving requirements, such as only allowing one-way driving, or driving speed lower than a limit speed. However, if the driver does not notice the road running requirements, or the driver mistakenly enters a road having a specific running requirement due to confusion caused by complex terrain, an illegal running phenomenon against the road running requirements is easy to occur, which endangers the road safety and is very likely to cause traffic accidents, thereby causing great harm.

Still taking the one-way road requiring one-way driving as an example, in the prior art, a sensor is usually deployed on the road, a retrograde vehicle is identified through the sensor, or a camera is adopted, the retrograde vehicle is identified through an image identification mode, and then a retrograde prompt is given to the driver or corresponding punishment measures are taken to encourage the driver to comply with the traffic rules. Then, the detection mode depends on hardware equipment, the problem of equipment aging exists, the detection accuracy is low, the vehicle can be only reminded under the condition that the vehicle is in violation, the potential safety hazard of the road cannot be effectively solved, and the phenomenon of illegal driving can occur on some roads due to objective reasons such as unobtrusiveness of road notice boards, so that the inventor thinks that if the roads in which the phenomenon of illegal driving easily occurs can be found, the potential safety hazard of the road can be solved to a certain extent by adopting corresponding safety measures.

The inventor finds that if the illegal vehicles are still identified by adopting a sensor or a camera, the detection accuracy is still low and the like when the number of the illegal vehicles is counted to determine whether the illegal vehicles are roads with high illegal driving phenomena.

In order to realize effective and accurate road detection, the inventor provides the technical scheme of the application through a series of researches, in the embodiment of the application, a running track set can be obtained, the running track set comprises more than one running track, then roads related to the running tracks are determined, and whether the running tracks are non-compliant running tracks on the matched roads is determined according to the matching degree of the running tracks and the related roads and the road running requirements; and then, acquiring a road with a matched running track meeting set conditions through statistical analysis. The road with the matched running track meeting the set conditions is the road with the high violation phenomenon, so that corresponding safety measures can be adopted for the road. According to the embodiment of the application, the road network information in any region can be subjected to statistical processing by carrying out statistical processing on a large number of running tracks, the coverage rate is high, hardware equipment is not relied on, the accuracy rate is high, and effective and accurate road detection is realized.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a flowchart of an embodiment of a detection method provided in an embodiment of the present application, where the method may include the following steps:

101: and acquiring a running track set.

Wherein the travel track set comprises more than one travel track; the driving track can be obtained by positioning of the client.

The client may be an on-board device disposed in a vehicle or a portable user terminal, such as a mobile phone, disposed in a vehicle and carried by a driver of the vehicle. The client may detect a travel track using a Global Positioning System (GPS), where the travel track may refer to a track point sequence formed by track points arranged in time sequence, the track points correspond to GPS coordinates, and a time interval between adjacent track points is within a predetermined time range. The client moves along with the vehicle, the driving track obtained by positioning the client means the driving track of the vehicle, and the vehicle can be a non-motor vehicle or a motor vehicle and the like.

In practical applications, the client may refer to a client that can run an electronic map or implement a navigation function or an early warning function based on the electronic map. The client may be when detecting that it is in a driving state. And obtaining the driving track by using GPS positioning. The client can be considered to be in a driving state when detecting that the driving speed is greater than a certain numerical value; or in the case where a navigation instruction is detected, it can be considered that the vehicle is in a traveling state, and thus a traveling locus can be obtained by positioning. Alternatively, the client may first output a notification message before locating the travel track to prompt the user to allow using the travel track, and after receiving a user confirmation request, the client may locate the travel track and upload the travel track to the server, and the like.

The server side can obtain a large number of driving tracks uploaded by the client sides and obtained by positioning, each client side can upload at least one driving track, and the like, and the driving tracks corresponding to different client sides form crowdsourcing driving tracks.

In the embodiment of the application, the travel track set may be a plurality of travel tracks collected within a predetermined time range, and may be obtained by positioning a plurality of clients, where the predetermined time range may be, for example, within 1 month or within 3 months, so that processing may be performed based on the travel tracks within a certain time range, and the detection accuracy is improved.

102: and determining a road associated with the driving track.

The road may be represented by a shape point sequence composed of a plurality of shape points, each shape point being a GPS point and corresponding to a GPS coordinate. The road network information stores information related to roads, such as road types, road signs, road driving requirements, shape point sequences, and the like. The road associated with the travel track may be determined in combination with the track point position and the road shape point position of the travel track.

As an alternative, a tile map associated with each driving track may be determined first; and screening the roads which are positioned on the tile map and have the preset road types as the roads associated with the driving track.

The tile map may be a grid map obtained by grid splitting an electronic map, and may be obtained by splitting a spatial index algorithm such as a TMS (tile map service) algorithm, an R-tree (R tree) algorithm, or an H3 (open source hexagonal hierarchical index grid algorithm), for example, which is not specifically limited in this application.

The tile map can be used for establishing an index relation between the preset type of roads and the driving track, and the driving track is necessarily attributed to the same tile map under the condition of being matched with the preset type of roads, so that the roads which are attributed to the same tile map with the driving track can be firstly screened and taken as the roads associated with the driving track, only the roads associated with the driving track are subjected to subsequent judgment, the calculated amount can be reduced, and the calculation efficiency is improved.

The predetermined type of road refers to a road having a certain type of road travel requirement, for example, a road allowing only one-way travel is referred to as a one-way road, and a road having a travel speed lower than a limit speed is referred to as a speed limit road.

Optionally, the tile map associated with each driving track may specifically be:

and taking the tile map in which the track point falls as the tile map associated with the driving track. It is known that each driving trajectory may be associated with a plurality of tile maps.

103: and determining whether the driving track is an unconventional driving track on the road matched with the driving track according to the matching degree of the driving track and the associated road and the road driving requirement.

The matching of the travel track with the associated road may be considered to be caused by the travel of the travel track on the road, and the non-compliant travel track may be a travel track against a road travel request, which may specify, for example, a travel direction, a travel speed, and the like, and may be a non-compliant travel track if the travel characteristics of the travel track do not comply with the road travel request.

The matching degree of the driving track and the associated road can be determined by judging the distance between the driving track and the road, and the matching degree can be determined by combining an angle and the like. For example, the minimum distance from each track point to the road in the driving track may be calculated, if the number of track points whose minimum distance is less than a certain distance meets a certain number requirement, if the minimum distance is greater than a certain numerical value or the ratio is greater than a certain proportion, the driving track may be considered to be matched with a predetermined type of road, otherwise, the driving track may not be matched, or an included angle between the driving track and the road may also be calculated, and if the included angle is less than a predetermined angle, the driving track may also be considered to be matched with the road, and the like. Since the driving track and the road may be formed by points, whether the track position is matched with the road position may be determined by converting the driving track and the road into a point or line form, determining whether the point or the line is matched with the line, and the like.

The road can be obtained from road network information, and the road network information can refer to road network information corresponding to a specific area, so that the purpose of detecting the road in the specific area can be realized by adopting the technical scheme of the application, and the specific area can refer to an area where a certain country is located, an area where a certain city is located, an area where a certain province is located, and the like.

104: and acquiring a road with the matched running track of the irregular running meeting the set condition.

Alternatively, the setting condition may refer to that the number of running trajectories of the matched irregular running is more than a predetermined number of times or the like. The matched road with the running track meeting the set conditions in the irregular running can be provided with a plurality of roads.

In the embodiment of the application, road excavation is realized aiming at the driving track in the driving track set. And determining whether the running track is an unconventional running track on the road matched with the running track according to the matching degree of the running track and the associated road and the road running requirement, and counting the unconventional running track to obtain the road with the matched running track meeting the set conditions, namely the road with the high-incidence illegal running phenomenon.

On the basis of the road on which the matched running track of the irregular running meets the set conditions, corresponding processing can be carried out, for example, related personnel are informed, corresponding road improvement measures can be made, and the like.

In addition, when the vehicle runs, the running position of the vehicle can be acquired, and when the running position meets the prompting condition, corresponding prompting information can be output.

In addition, as another embodiment, a road with a running track meeting a set condition of the matched irregular running may be specifically marked in the electronic map, so that when the client runs the electronic map and detects that the running position meets the prompt condition, the client may output prompt information corresponding to a target predetermined type road to prompt the user that the target predetermined type road is a road with a high violation phenomenon, thereby implementing an early warning effect.

The presentation condition may be, for example, that the traveling position is close to the road satisfying the setting condition, and the traveling position is considered to be close to the road when the traveling position close to the road is judged to be within a predetermined distance range from the road or when the road on which the traveling position is located is adjacent to the road. When the road is a one-way road, the distance between the driving position and the one-way road may be a distance between the driving position and an end shape point of the one-way road. Therefore, the road can be reminded when the vehicle does not drive into the road, a better early warning effect is realized, the violation phenomenon is avoided, and the road safety is further improved.

In one practical application, the predetermined type may refer to a one-way road, and therefore, the screening, as the road associated with the driving track, the road located on the tile map and having the predetermined type of road may include:

The road library may be pre-created, and thus, in some embodiments, the method may further comprise:

The road information may include related information such as road identifiers, shape point sequences, and road driving requirements.

The driving track and the one-way road belonging to the same tile map can be quickly searched based on the tile identification.

Optionally, for the unidirectional road, an index relationship between the road information of the unidirectional road and the identifier of the tile map to which the end shape point belongs may be specifically established. Therefore, in a case that the predetermined type of road is a one-way road, the indexing, from the road library, the one-way road located on the tile map as the road associated with the driving track according to the identifier of the tile map associated with each driving track may include:

and according to the identification of the tile map associated with each driving track, indexing a one-way road with the tail end shape point positioned on the tile map from a road library as the road associated with the driving track.

For a one-way road, in some embodiments, determining whether the driving track is an irregular driving track on the road matched with the driving track according to the matching degree of the driving track and the associated road and the road driving requirement may include:

and determining whether the track driving direction is consistent with the driving direction of the matched road so as to determine whether the driving track is an irregular driving track on the matched road.

The minimum distance from each track point in the driving track to each associated road may be calculated, and if the number of track points of which the minimum distance is smaller than the predetermined distance threshold satisfies the condition of sufficient number, the associated road is the road matched with the driving track.

Because the shape points of the associated road form a straight line or a curve, the minimum distance from the track point to the associated road can be calculated according to a calculation formula from point to straight line or from point to curve, and the description is omitted here.

The number condition may be, for example, that the number of track points whose minimum distance is smaller than the predetermined distance threshold is greater than the predetermined number, or that the ratio of the number of track points whose minimum distance is smaller than the predetermined distance threshold to the total number is greater than a predetermined ratio, such as 80%, and the like, the travel track may be considered to be matched with the associated road, otherwise, the travel track is not matched.

Of course, as another implementation manner, an included angle between the driving track and the associated road may also be calculated, and if the included angle is smaller than a predetermined angle, and/or the number of track points whose distance is smaller than a predetermined distance satisfies a number condition, the driving track is considered to be matched with the associated road.

In some embodiments, determining the distance of a track point in the travel track to the associated road may include:

for each associated road, intercepting a section of track from the driving track;

determining the distance from the track point in the track segment to the corresponding associated road

One driving track may be associated with a plurality of roads, and for each road, a section of track corresponding to the road may be intercepted from the driving track, and the specific intercepting manner may be, for example: and taking the track points belonging to the same tile map with the road as initial track points, and intercepting a certain number of track points backwards from the initial track points to form a section of track corresponding to the road, wherein the certain number can be preset or determined by combining the length of the road and the like.

When the one-way road has the illegal driving phenomenon, namely when the one-way road is driven reversely, the one-way road is driven in from the tail end of the road, and optionally, a track point which belongs to the same tile map as the tail end shape point of the one-way road can be specifically used as an initial track point.

As can be known from the foregoing description, in an actual application, the technical solution of the present application may be applicable to detection of a one-way road, and the following describes the technical solution of the present application by taking the detection of the one-way road as an example, as shown in fig. 2, a flowchart of another embodiment of a detection method provided in an embodiment of the present application may include the following steps:

201: the method comprises the steps of obtaining a running track set, wherein the running track set comprises more than one running track.

202: and determining a one-way road associated with the driving track.

203: and determining whether the running track is an unconventional running track on the road matched with the running track according to the matching degree of the running track and the associated one-way road and the running direction of the road.

204: and acquiring the one-way road with the matched running track meeting the set conditions.

The difference between the operations in step 201 to step 203 and the operations in step 101 to step 103 in the embodiment shown in fig. 1 is that the road is specifically a unidirectional road, and other identical or similar steps can be detailed as shown in the embodiment shown in fig. 1 and are not described herein again.

In some embodiments, the method may further comprise:

and marking the road with the matched running track meeting the set conditions in the electronic map so as to output prompt information when the electronic map runs and detects that the running position is close to the road, thereby realizing the aim of reminding the user.

The prompt information can comprise sub prompt information in the forms of characters, images and/or sounds and the like, so that the purpose of remarkably reminding a user is achieved, and the early warning effectiveness is improved.

As shown in fig. 3, an embodiment of the present application further provides a prompting method, where the technical solution of the present embodiment is executed by a client, and may include the following steps:

301: and acquiring a driving position.

302: it is determined whether the driving location is close to the road determined based on the detection method of the embodiment shown in fig. 1, if so, step 303 is performed.

The road determined by the detection method according to the embodiment shown in fig. 1 means a road whose driving track meets the set conditions, and the driving track meets the set conditions, and is matched with the driving track in the non-compliant driving according to the technical scheme of the embodiment shown in fig. 1. The specific determination method can be detailed in the foregoing embodiments, and is not described herein again.

303: and outputting corresponding prompt information.

In addition, the client can also obtain the driving track in a positioning mode and upload the driving track to the server, so that the server can use the driving track as one of crowdsourcing driving tracks, participate in road detection according to the technical scheme of the embodiment of the application and determine the target preset type road.

Wherein, outputting the corresponding prompt information may include: and displaying the prompt information corresponding to the road by using characters and/or images. Such as displaying the prompt message in a display interface of the electronic map.

In addition, the acquisition of the driving position can be realized by outputting an electronic map at the client and detecting and acquiring the driving position when the electronic map is in a navigation state, the prompt information can be correspondingly displayed in a navigation interface, and the like,

whether the travel position is close to the road determined based on the detection method of the embodiment shown in fig. 1 may be determined according to whether the travel position is within a predetermined distance range from the road, or whether the road on which the travel position is located is adjacent to the road, or the like. When the road is a one-way road, the distance between the driving position and the road may be a distance between the driving position and an end shape point of the road. Therefore, the road can be reminded before the vehicle enters the road, a better early warning effect is realized, the violation phenomenon is avoided, and the road safety is further improved.

When the road is a one-way road, the one-way road with the high-occurrence retrograde motion phenomenon can be effectively and accurately excavated by adopting the technical scheme of the application, and the aim of the retrograde high-occurrence early warning is fulfilled

For convenience of understanding, a one-way road is taken as an example, and the technical solution of the present application is introduced in conjunction with the scene interaction diagram shown in fig. 4, assuming that road detection is performed on a target area, first, the server 401 may collect crowdsourcing driving tracks, that is, driving tracks uploaded by a plurality of clients 402. The client 402 may be a client capable of running an electronic map, and certainly may also be a client capable of performing GPS detection, and the client may be configured on a vehicle-mounted device in a vehicle, or may be configured on a portable mobile terminal of a user, so as to achieve the purpose of detecting a driving track of the vehicle in the driving process of the vehicle.

The server side can screen out the one-way road from the road network information of the electronic map of the target area, determine the tile map tile to which the tail end shape point of the one-way road belongs, establish the index relation with the road information based on the identification tile of the tile map tile to which the one-way road belongs, and store the index relation in the one-way road library.

Then, determining a driving track set in a preset time range, namely crowdsourcing driving tracks collected in the preset time range, determining a tile map in which each track point falls for the position of each track point in each driving track, taking the tile map as a driving track-associated tile map, and indexing a one-way road located in the tile map from a one-way road library based on tileids of the driving track-associated tile map to serve as the one-way road associated with the driving track; then, the track driving direction can be determined based on the track points of the driving track; determining the distance from the track points to the associated one-way road, and if the number of the track points with the distance smaller than a preset distance threshold value meets a number condition, taking the one-way road associated with the driving track as a road matched with the driving track; and then determining whether the track driving direction is consistent with the road driving direction of the matched one-way road, if not, determining that the driving track is an unconventional driving track on the matched road, otherwise, determining that the driving track is a compliant driving track.

And then, acquiring the matched one-way road with the running track meeting the set condition, so that based on the one-way road meeting the set condition, when the running position is detected to be close to the one-way road in the running process of the vehicle, the corresponding prompt information is output to realize the early warning purpose.
