Abstract

The invention provides a display method and a display device for planned roads. The display method includes displaying the planned roads on the navigation interface by the aid of a linear scale with preset graduation according to the length of the planned roads; periodically detecting road conditions and / or traffic accidents, and indicating the road conditions and / or the traffic accidents on the planned roads displayed if the road conditions and / or the traffic accidents are detected on the planned roads. By displaying the planned roads by the aid of the scale and displaying the detected road conditions and traffic accidents on the planned roads and the scale, the display method and the display device for planned roads have the advantages that displaying all the road conditions on the navigation interface is avoided, system resources are saved, and road conditions, directions of the roads and traffic accidents on the planned roads can be displayed at the same time.

Description

[0001] This application claims the priority of the Chinese application filed on December 31, 2011 with the application number 201110458422.X and the title of the invention "A Display Method and Device for Planned Route", the entire content of which is incorporated in this application by reference middle. technical field [0002] The invention provides a method and device for displaying a planned route, belonging to the technical field of navigation. Background technique [0003] The existing TMC (Traffic Message Channel, real-time traffic information) generally uses three colors of red, yellow and green to identify road conditions, that is, red indicates severe congestion, yellow indicates slow driving (driving speed below 15 kilometers per hour), and green indicates smooth traffic. . However, this road condition marking method has the following defects: [0004] 1. All road networks are covered by TMC information signs, affecting users' observation of road networks; [0...
