Abstract

The invention discloses a navigation information prompting method and device based on a line. The method comprises the following steps of: 1) respectively carrying out same road matching to each real-time information road section coding schedule which represents road condition and event information and the road section coding schedule of each road section in navigation map data in advance; 2) uniformly compiling the road section coding schedule of real-time information road condition and the event information into a self-defined index; 3) building an index mapping table of a direct corresponding relationship for the road section coding schedule in the map data and the self-defined index compiled in step 2); 4) according to the road section coding schedule of a line selected by a user in the map data, inquiring the index mapping table in step 3) to obtain an index for representing the real-time information of the corresponding line; and 5) according to the index obtained in step 4), obtaining the real-time information of the corresponding line, and showing to the user in a user interface (UI) widget mode.

Description

technical field [0001] The invention belongs to the technical field of navigation applications, and in particular relates to a route-based navigation information prompting method and device. Background technique [0002] Due to the increasingly congested urban traffic and the rapid increase in the number of vehicles, the public's demand for traffic information is no longer simply dragging the map to view the traffic conditions in a certain area, but directly viewing the route set by themselves during the busy driving journey The road conditions and event information along the line ahead, and you can easily locate and view the corresponding road sections of the road conditions and event information along the line. Such a method for quickly viewing and locating road conditions and event information along the road not only provides users with a novel way of viewing road conditions, but also reduces distraction while driving and improves driving safety. [0003] The existing ro...
