Problems solved by technology

However, the current map data only has the data of the main road and the auxiliary road, does not show the relationship between the main road and the auxiliary road, and cannot determine which main road the auxiliary road belongs to; it does not indicate whether the road intersection is a level crossing, and it is impossible to know the main road. Whether the auxiliary road needs to be guided will bring great inconvenience to the follow-up navigation and lead to misleading

Embodiment 1

[0081] According to an embodiment of the present invention, an embodiment of a navigation method for a main and auxiliary road is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0082] In some optional embodiments, a navigation method for main and auxiliary roads is provided, such as figure 1 As shown, the following S101-S105 may be included.

[0083] S101: Obtain road attribute information and traffic rules of the entry road and all exit roads;

[0084] In some optional embodiments, the currently implemented traffic rules include: left traffic rules and right traffic rules, for the matching of main and auxiliary roads of roads and the determination and guidance of...

example 1

[0139] Example 1: If image 3 In (A), A is the entry road. When there are two first-class roads directly connected to the entry road A in the direction of travel, they are numbered as B and C in the counterclockwise direction, and they are in the direction of travel with the first-class road B. The directly connected second-class roads are numbered D and E counterclockwise, and the second-class roads directly connected to the first-class road C in the direction of travel are numbered F and G counterclockwise.

example 2

[0140] Example 2: If image 3 In (B), A is the entry road. When there are three first-class roads directly connected to the entry road A in the direction of travel, they are numbered counterclockwise as B, C and D, and they are in the direction of travel with the first-class road B. The second-level roads directly connected to the upper road are numbered as E, F and G in the counterclockwise direction, and the second-level roads directly connected to the first-level road D in the direction of travel are numbered as H and I in the counter-clockwise direction. Class road C has no directly connected roads in the direction of travel.

Abstract

The invention provides a main and auxiliary road navigation method and device. The method comprises the following steps: acquiring road attribute information and traffic rules of an entrance road andall exit roads, wherein the traffic rules comprise a left side passing rule and a right side passing rule; sequentially carrying out main and auxiliary road matching on all the exit roads to obtain all the matched main roads and auxiliary roads in the exit roads based on the road attribute information and the traffic rules; judging whether the intersections where the entrance road and all the exitroads are located are main and auxiliary road level intersections or not, and if yes, determining the guide directions of all the exit roads of the entrance road according to the matched main road and auxiliary road in the exit roads respectively; and determining the guiding direction of the planned departure path according to the navigation planning path. Whether the main road and the auxiliaryroad need to be guided or not is judged by recognizing the main road to which the auxiliary road is attached in the current intersection and whether the road model is the level crossing or not so thatcorrect guiding of the main road and the auxiliary road is achieved and wrong guiding navigation is avoided.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and device for main and auxiliary roads. Background technique [0002] In map data, main roads and auxiliary roads are very important geographical information. However, the current map data only has the data of the main road and the auxiliary road, and does not show the relationship between the main road and the auxiliary road. It is impossible to determine which main road the auxiliary road belongs to; Whether the auxiliary road needs to be guided will bring great inconvenience to the follow-up navigation guidance and easily cause misleading. [0003] In the map data, auxiliary roads are small roads that are parallel and similar to the main road. Common auxiliary roads include: auxiliary roads that share the traffic flow of the main road, and those that do not share the traffic flow of the main road. They exist only as a naming; there is another situation...
