Abstract
Disclosed herein are a method and apparatus for providing traffic information for a public transportation means, such as a bus, and utilizing the provided information. A method of encoding traffic information according to the present invention creates information about a bus route, creates identification information for the route, identification information for respective stops belonging to the route and information about travel time, creates identification information indicating that the type of traffic information to be encoded is route-based public traffic information, and constructs a message segment including the created information. A sequence of multiple message segments constructed as described above is wirelessly transmitted.
