Currently, a driver of a vehicle can generally perform driving control of the vehicle based on driving instruction information laid on a road, such as traffic lights, lane markings, road signs, and the like.
However, in some cases, for example, since the running instruction information laid on the road is not comprehensive and the running instruction information of some roads may be lacking, the driver may not know which direction of the road can be run and which direction of the road cannot be run, so that the reliability and safety of the running of the vehicle are not high.
Therefore, it is desirable to provide a method for indicating the passing of a road intersection to improve the safety and reliability of the navigation service.
Fig. 1A is a schematic flowchart of a method for indicating the passing of a road intersection according to an embodiment of the present application, as shown in fig. 1A.
101. A road intersection through which the vehicle is to pass is determined.
102. And according to the navigation path of the vehicle, obtaining the safe passing driving information of the road intersection on the navigation path.
103. And outputting the safe passing driving information of the road intersection on the navigation path.
The safe passing information of the road intersection is used for instructing that when a vehicle passes through the road intersection, the vehicle does not have a vehicle running abnormality, such as a vehicle collision, a vehicle running error, a vehicle detour, and the like, for example, when the vehicle exits from a road corresponding to the road intersection and enters another road corresponding to the road intersection. In this way, the user can control the vehicle to safely pass through the road junction based on the output safe passing travel information of the road junction on the navigation path.
It should be noted that part or all of the execution subjects of 101 to 103 may be an application located at the local terminal, or may also be a functional unit such as a plug-in or Software Development Kit (SDK) set in the application located at the local terminal, or may also be a processing engine located in a server on the network side, or may also be a distributed system located on the network side, for example, a processing engine or a distributed system in a navigation platform on the network side, and the like, which is not particularly limited in this embodiment.
It is to be understood that the application may be a native app (native app) installed on the terminal, or may also be a web page program (webApp) of a browser on the terminal, which is not limited in this embodiment.
In this way, by determining the road intersection through which the vehicle will pass and then obtaining the safe passing driving information of the road intersection on the navigation path according to the navigation path of the vehicle, the safe passing driving information of the road intersection on the navigation path can be output, so that a user can control the vehicle to safely pass through the road intersection based on the output safe passing driving information of the road intersection on the navigation path, the technical problem of abnormal vehicle driving caused by completely depending on road network data to provide navigation service for the user can be effectively avoided, and the safety and the reliability of the navigation service are improved.
Optionally, in a possible implementation manner of this embodiment, before 102, at least two roads corresponding to the road intersection may be further determined. Specifically, the road sections corresponding to the road intersections may be obtained, and road merging processing is performed on the road sections according to the road section attributes of the road sections of the road intersections, so as to determine at least two roads corresponding to the road intersections. The road section refers to a traffic line between two adjacent road intersections on a traffic network.
For example, the road segments traveled by non-motor vehicles having a parallel relationship may be merged with the road segments traveled by motor vehicles. The parallel relationship referred to herein does not require that the directions of the two links be completely parallel, and two links can be considered to have a parallel relationship as long as the directions of the two links are substantially the same.
Alternatively, for another example, links constituting one up-down separation road having a parallel relationship may be merged. The parallel relationship referred to herein does not require that the directions of the two links be completely parallel, and two links can be considered to have a parallel relationship as long as the directions of the two links are substantially the same.
Alternatively, for another example, the secondary roads having a parallel relationship may be merged with the corresponding primary road. The parallel relationship referred to herein does not require that the directions of the two links be completely parallel, and two links can be considered to have a parallel relationship as long as the directions of the two links are substantially the same.
At this time, the road sections with the parallel relation are merged according to the road section attributes of the road sections of each road intersection, so that the processed road sections corresponding to each road intersection are simplified into the roads capable of passing in two directions, and the occupation condition of the analysis processing of the navigation service on system resources can be effectively reduced.
In an implementation manner, the at least two roads determined in the implementation manner may include, but are not limited to, a public road and/or a non-public road, for example, may include only a public road, or may further include only a non-public road, or may further include both a public road and a non-public road, for example, which is not particularly limited in this embodiment.
In the present application, the road may be a road, an urban road, a place where social motor vehicles are allowed to pass through although the place is under the jurisdiction of a unit, or the like. The public road is a road that is open to general social people and through which many unspecified vehicles and pedestrians can pass at the same time. The non-public road is a road that is open to a specific person and through which a specific small number of vehicles and pedestrians can pass.
After determining at least two roads corresponding to the road junction, the junction structure of the road junction, such as a three-way junction, a four-way junction, etc., can be determined according to the at least two roads. Then, the traffic flow of each road in the at least two roads at the road intersection can be obtained according to the intersection structure.
For example, assuming that a road intersection is determined to correspond to 4 roads, the intersection structure of the road intersection can be determined to be a four-branch intersection.
Specifically, the driving instruction information of each road at the road intersection, such as instruction type instruction information for turning left, turning right, going straight, etc., and prohibition type instruction information for prohibiting turning left, prohibiting turning around, etc., may be obtained. Furthermore, the traffic flow of each road in the at least two roads at the road intersection can be obtained according to the intersection structure and the driving instruction information.
For example, assuming that a road intersection is determined to correspond to 4 roads, the intersection structure of the road intersection can be determined to be a four-branch intersection. Then, the traffic flow of any one road of the road junction entering into other three roads and the traffic flow of other three roads entering into any one road can be analyzed according to the intersection structure of the four-way intersection and the driving indication information of each road at the road intersection.
And finally, obtaining the safe passing driving information of the road intersection according to the traffic flow of each road at the road intersection.
Specifically, the safe passing information of the road intersection can be obtained according to a safe passing principle, such as a vehicle running proximity principle, a vehicle running collision avoidance principle, and the like.
In the present application, the safety passing driving information of the road intersection may include, but is not limited to, at least one of driving information at a lane level of the road intersection and driving information at a non-lane level of the road intersection, which is not particularly limited in the present embodiment.
In this way, by using the driving information at the lane level of the road intersection as the safe passing driving information of the road intersection, the traffic safety of driving can be further ensured.
The following will describe the technical solution provided by the present application in detail by taking the intersection structure of a road intersection as a four-way intersection as an example, as shown in fig. 1B. The roads 1, 2 and 3 are public roads, that is, the public roads 1, 2 and 3, and usually have related driving instruction information to constrain and specify them, while the road a is a non-public road, that is, a non-public road a, and usually has no related driving instruction information to constrain and specify them.
After determining that the intersection structure of the road intersection is a four-branch intersection, obtaining driving indication information of each public road (namely, the public road 1, the public road 2 and the public road 3) at the four-branch intersection, such as indication type indication information of turning left, turning right, going straight and the like, and prohibition type indication information of prohibiting turning left, turning around and the like, and further obtaining traffic flow of each road (the public road 1, the public road 2, the public road 3 and the non-public road a) at the road intersection according to the intersection structure and the driving indication information, as shown by an arrow in fig. 1B.
Finally, the travel condition of each traffic flow, for example, a normal travel traffic flow, a traffic flow in which abnormal travel may occur, or the like, may be determined from the traffic flow of each road (the public road 1, the public road 2, the public road 3, and the non-public road a) at the road intersection, and the safe passing travel information of the road intersection may be obtained based on the travel condition of each traffic flow.
For example, since the traffic flow entering the non-public road a from the public road 1 does not conflict with the traffic flows entering the public roads 2 and 3 from the public road 1, the safe-passage travel information of the road intersection may be: when the left turn signal lamp turns green, the public road 1 can safely go straight into the non-public road A.
Alternatively, for another example, since the traffic flow entering the non-public road a from the public road 2 conflicts with the traffic flow entering the public road 2 from the public road 3, the safe passage travel information of the road intersection may be: when the straight traffic light turns green, the non-public road a cannot be safely entered by the left turn of the public road 2.
Alternatively, for another example, since the traffic flow entering the non-public road a from the public road 3 does not conflict with other traffic flows, the safe passage travel information at the road intersection may be: the user can confirm to observe well and safely turn right from the public road 3 to enter the non-public road A.
Alternatively, for another example, since the traffic flow entering the non-public road a from the public road 1 does not conflict with the traffic flows entering the public roads 2 and 3 from the public road 1, the safe passage travel information of the road intersection may be: when the left turn signal light turns green, the non-public road A can be safely entered straight from the public road 1 through the rightmost left turn lane. In this way, it can be further ensured that no collision occurs in the lane level.
Optionally, in a possible implementation manner of this embodiment, in 102, it may be specifically determined that the vehicle is going to exit from a first road corresponding to the road intersection and enter a second road corresponding to the road intersection according to the navigation path of the vehicle, and further, safe passing driving information that the vehicle is going to exit from the first road and enter the second road may be obtained based on the safe passing driving information of the road intersection obtained in advance.
According to the method and the device, various existing output modes, such as a voice mode, an indication icon mode, a character mode and the like, can be adopted to output the safe passing driving information of the road intersection on the navigation path.
According to the method and the device, the relation between the traffic streams of the roads at the road junction can be comprehensively judged according to the existing driving indication information of the roads at the road junction in the real world, and one piece of safe passing driving information can be obtained for each direction of the roads at the road junction, so that a user is guided to control the vehicle to safely pass through the road junction.
In this embodiment, by determining a road intersection through which a vehicle will pass and then obtaining safe passing driving information of the road intersection on the navigation path according to the navigation path of the vehicle, the safe passing driving information of the road intersection on the navigation path can be output, so that a user can control the vehicle to safely pass through the road intersection based on the output safe passing driving information of the road intersection on the navigation path, and the technical problem of abnormal vehicle driving caused by completely depending on road network data to provide navigation service for the user can be effectively avoided, thereby improving the safety and reliability of the navigation service.
In addition, by adopting the technical scheme provided by the application, the safe passing driving information of each road intersection can be obtained in advance by considering the intersection structure of the road intersection and the traffic flow of each public road and non-public road corresponding to the road intersection, so that the safe passing driving information of the road intersection which is about to be passed by a user on a navigation path can be obtained in time in the navigation process and provided for the user for reference, and the timeliness of the navigation service can be effectively improved.
In addition, by adopting the technical scheme provided by the application, the road sections with the parallel relation are merged according to the road section attributes of the road sections of the road intersections, so that the processed road sections corresponding to the road intersections are simplified into the roads capable of passing in two directions, and the occupation condition of the analysis processing of the navigation service on the system resources can be effectively reduced.
In addition, by adopting the technical scheme provided by the application, the traffic flow of each road at the road intersection is obtained based on the driving indication information of each road at the road intersection provided by the traffic control department, and the accuracy of the navigation service can be effectively improved.
In addition, by adopting the technical scheme provided by the application, the driving information of the lane level of the road intersection is used as the safe passing driving information of the road intersection, so that the driving traffic safety can be further ensured.
In addition, by adopting the technical scheme provided by the application, the user experience can be effectively improved.
