ROUTE PLANNING SYSTEM, ROUTE PLANNING METHOD AND TRAFFIC INFORMATION UPDATE METHOD
First Claim
1. A route planning system comprising:
- a network server comprising a plurality of road section data, wherein each road section data comprises a distance and a plurality of average speed rate data corresponding to a plurality of time intervals;
wherein the route planning system calculates at least one possible route according to a departure time, a departure point, and a destination point;
wherein the at least one possible route comprises a plurality of possible road sections from the departure point to the destination point, and the route planning system dynamically searches the average speed rate data of the corresponding time intervals of a plurality of estimated passing time according to the possible road sections and the distances respectively to receive at least one total travel time of the at least one possible route;
wherein dynamically searching the average speed rate data of corresponding time intervals according to the possible road sections and the distances comprises searching the time intervals of each estimated passing time of the possible road sections starting from the departure time sequentially to receive the average speed rate data of the possible road sections at each estimated passing time.

Abstract
A route planning system includes a network server. The network server includes a plurality of road section data, in which each road section data includes a distance and a plurality of average speed rate data corresponding to a plurality of time intervals. The route planning system calculates at least one possible route according to a departure time, a departure point, and a destination point. The possible route includes a plurality of possible road sections from the departure point to the destination point. The route planning system dynamically searches the average speed rate data of the estimated passing time intervals according to the possible road sections and the distances respectively to calculate the travel time of each possible road section and adds them to receive a total travel time of the possible route.
