Embodiment Construction

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0037] The embodiment of the present invention aims at the problem that the navigation data model in the prior art uses a one-dimensional line segment to represent the road, which cannot well describe various attribute information related to the lane, so that it cannot provide accurate guidance for drivers, and provides a A navigation implementation method and device can accurately guide drivers based on lanes.

[0038] figure 1 It is a schematic flow diagram of the navigation implementation method of the embodiment of the present invention, such as figure 1 As shown, this embodiment includes:

[0039] Step 101: Establish the connectivity relationship between lanes of different roads according to the electronic map containing lane in...

Abstract

The invention provides a navigation implementation method and a navigation implementation apparatus, and belongs to the navigation field. The navigation implementation method comprises the steps of establishing connective relationships among traffic lanes in different roads according to an electronic map containing traffic lane information; acquiring path planning of a user and the traffic lane that the user is in at present; determining an exit traffic lane according to the connective relationships and the path planning; displaying the exit traffic lane on a navigation terminal of the user so as to realize the navigation for the user. Technical solution provided by the invention can provide accurate guidance to a driving personnel based on the traffic lanes.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a navigation realization method and device. Background technique [0002] Traditional navigation data models use one-dimensional line segments to represent roads, which cannot describe various attribute information related to lanes well. Because the road in the real world is not a simple one-dimensional line segment, but a surface entity with a certain width, which is a complex object composed of multiple lanes. In vehicle navigation or network analysis, the characteristics of the road are not equivalent to the lanes. The characteristics include: different directions of the same road, lanes have different traffic characteristics; lanes in different directions of the same road and adjacent lanes often have different topological relationships; Part is for driveways. [0003] Therefore, it is very important for motorists to know the specific information of each lane. Lane-based road gui...
