Abstract

The invention provides a navigation method, a navigation apparatus and a real-time navigation system. The navigation method comprises: obtaining a programmed routine through the real-time navigation system; determining crossing guiding points on the programmed routine; determining guiding-point information for each crossing guiding point, wherein the guiding-point information at least comprises a guiding direction, a guiding-point track list and tract data corresponding to tracks; and displaying the track data about a current track and subsequent multiple tracks according to the guiding-point information before a user arrives at a destination. According to the technical scheme, the track information about the current track and the subsequent multiple tracks are displayed to a user, and relatively comprehensive road condition information is provided for the user.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a navigation method, device and real-time navigation system. Background technique [0002] The current navigation system is based on the road network model of geographic information system data GIS, and the expression of this model mainly includes: point, line and plane. In the urban road network model, it is necessary to use point models to describe expressway entry points, expressway exit points, expressway divergence points, and ordinary road intersections, and use line models to describe road information. [0003] The model is composed of nodes, roads, points of interest, etc. [0004] Among them, a node has a unique number and is the intersection of two or more roads. And information such as node type (expressway entrance, expressway exit, expressway divergence, ordinary road intersection, etc.), traffic regulations, and the list of consecutive road numbers can be recorded in the...
