SELECTING ROUTE ACCORDING TO TRAFFIC INFORMATION
First Claim
Patent Images
1. A method of selecting a travel route, the method comprising:
- receiving message information that includes traffic information;
determining whether the message information includes message management information including time information for message management, status information indicating current traffic congestion status information or predicted traffic congestion status information, and location information including link identifiers assigned to road sections each indicating a location corresponding to the current traffic congestion status information or the predicted traffic congestion status information;
receiving first and second location values for searching the travel route; and
calculating travel prediction information of all road sections from a first position to a second position by applying each weight value previously set for each road section according to at least one of the current traffic congestion status information and the predicted traffic congestion status information from the first position to the second position that correspond to the first and second position values.

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.

17. An apparatus for selecting a travel route, the apparatus comprising:
-
a receiving device configured to receive message information including traffic information; a traffic information extracting unit configured to determine whether the message information includes message management information including time information for message management, status information indicating current traffic congestion status information or predicted traffic congestion status information, and location information including link identifiers assigned to road sections each indicating a location corresponding to the current traffic congestion status information or the predicted traffic congestion status information, and to extract the current traffic congestion status information or the predicted traffic congestion status information; an input unit configured to receive first and second location values for searching the travel route; and a processing device configured to calculate travel prediction information of all road sections from a first position to a second position by applying each weight value previously set for each road section according to at least one of the current traffic congestion status information and the predicted traffic congestion status information from the first position to the second position that correspond to the first and second position values. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
