1. A method of selecting a travel route, the method comprising:
- receiving message information, the message information comprising location information including link identifiers assigned to road sections, and traffic information including current traffic status information and predicted traffic status information, the current traffic status information comprising at least one of an average speed, a travel time and a congestion type for each road section, the predicted traffic status information comprising at least one of a predicted speed, a predicted travel time and congestion tendency information;
obtaining a weight value for each road section based on the congestion type and the congestion tendency information for a corresponding road section;
receiving first and second location values for searching a travel route;
calculating travel prediction information of the entire road sections from a first position to a second position by applying each weight value for each road section from the first position to the second position; and
selecting an optimum route according to the travel prediction information calculated for each possible route from the first position to the second position.

Abstract
A method and apparatus for selecting a travel route in which first and second positions values for searching a travel route are received, and travel prediction information of all road sections from a first position to a second position are calculated by applying a pre-set weight value to each road section according to at least one of current traffic congestion status information and predicted traffic congestion status information from the first position to the second position that correspond to the first and second position values.

11. An apparatus for selecting a travel route comprising:
-
a receiving device configured to receive message information, the message information comprising location information including link identifiers assigned to road sections, and traffic information including current status information and predicted traffic status information, the current traffic status information comprising at least one of an average speed, a travel time and a congestion type for each road section, the predicted traffic status information comprising at least one of a predicted speed, a predicted travel time and congestion tendency information; the receiving device further configured to obtain a weight value for each road section based on the congestion type and the congestion tendency information for a corresponding road section; an input configured to receive first and second location values for searching a travel route; and a processing device configured to calculate travel prediction information of the entire road sections from a first position to a second position by applying each weight value for each road section from the first position to the second position and to select an optimum route according to the travel prediction information calculated for each possible route from the first position to the second position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 22)
