System and method for estimating drive elapsed time using road traffic condition information
First Claim
1. A method for estimating a drive elapsed time using road traffic condition information, the method comprising:
- (a) when destination information is inputted from a user, receiving search path information from a present location to a destination;
(b) determining whether a car is in a real time traffic information collection section for each link from the present location to the destination using the search path information, and estimating passing time for each link using information on whether to collect real time traffic information;
(c) determining whether a waiting time is applied according to each of the links using the search path information, and estimating additional elapsed time; and
(d) estimating a total drive elapsed time by summing the passing time for each link and additional elapsed time.

10. A system for estimating a drive elapsed time using road traffic condition information, comprising:
-
a GPS unit for providing present location information of a car;
a path search server for providing search path information from a present location to a destination with reference to destination information inputted by a user; and
a CNS (car navigation system) for obtaining a passing time for each link from a present location to a destination and an additional elapsed time using real time search path information transmitted from the path search server or stored search path information, and then obtaining a total drive elapsed time by summing the obtained passing time for each link and the obtained additional elapsed time. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
