Abstract

The invention provides a navigation method, a navigation device, an electronic map system and a generation method, which relate to the field of electronic maps and aim to solve the technical problem that the navigation device in the prior art cannot avoid congested road sections. The navigation method comprises the following steps of: a, acquiring a starting position and a destination position; b, selecting a road section between the starting position and the destination position according to un-obstruction information, a driving speed and the time of starting from the starting position preset for the road section; and c, performing navigation according to the selected road section. The navigation method, the navigation device, the electronic map system and the generation method can be used in the field of navigation to avoid the congested road sections.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a navigation method and a navigation device in the field of electronic maps. Background technique [0002] In urban traffic, there are often congested situations that make vehicles move slowly. In the prior art, general navigation systems do not have road congestion information, so it is difficult to avoid congested road sections during navigation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a navigation method, a navigation device, an electronic map system and a generating method, which can avoid congested roads. [0004] In order to solve the above technical problems, embodiments of the present invention provide technical solutions as follows: [0005] In one aspect, a navigation method is provided, including: [0006] Step a, obtaining the starting position and the target position; [0007] Step b, selecti...
