MOBILE NAVIGATION METHOD AND DEVICE FOR ROUTE PLANNING
First Claim
1. A mobile navigation method, applied to a mobile device using a Global Positioning System (GPS) navigation program, wherein the mobile device receives a destination, and is used to plan a main vehicle driving route according to the destination, and the main vehicle driving route comprises a plurality of road sections, and the mobile navigation method comprises:
- determining whether the main vehicle driving route comprises at least one congestion-prone road section or not;
if the determination is that the main vehicle driving route comprises the at least one congestion-prone road section, planning a backup vehicle driving route on a road section leading to the congestion-prone road section for bypassing the congestion-prone road section to arrive at the destination; and
following the main vehicle driving route, and deciding, before reaching the congestion-prone road section, whether to switch to following the backup vehicle driving route as a substitute for the main vehicle driving route according to an actual obtained traffic condition of the congestion-prone road section.

Abstract
A mobile navigation method and device of route planning are provided. The method and the device enable a user to drive on a backup vehicle driving route in advance when discovering a congestion-prone road section is in poor condition. The method includes the following steps. Firstly, it is determined whether the main vehicle driving route includes at least one congestion-prone road section or not. If the main vehicle driving route includes at least one congestion-prone road section, a backup vehicle driving route is planned in a road section ahead of the congestion-prone road section. Then, it is determined whether the backup vehicle driving route is substituted for the main vehicle driving route according to an actual obtained traffic condition of the congestion-prone road section.

11. A mobile navigation device, using a Global Positioning System (GPS) module, wherein the Global Positioning System module is used to plan a main vehicle driving route according to a destination, and the main vehicle driving route comprises a plurality of road sections, and the mobile navigation device comprises:
-
a storage module, for storing information about at least one congestion-prone road section; a determining unit, for determining whether or not the main vehicle driving route comprises said at least one congestion-prone road section whose information is stored in the storage module; a receiving module, for receiving real-time broadcast messages and obtaining information about an actually congested road section accordingly; and a route generator, for generating a backup vehicle driving route if it'"'"'s determined that the main vehicle driving route comprises said at least one congestion-prone road section, and substituting the backup vehicle driving route for the main vehicle driving route if the actually congested road section matches the congestion-prone road section. - View Dependent Claims (12, 13, 14, 15)
