Abstract
Disclosed herein is a method and apparatus for providing traffic information of public transportation means, such as a bus, and utilizing the provided information. A method of encoding public traffic information according to the present invention creates an identifier of bus information system, an ID of bus route, and travel time on each section wherein the section is link between neighboring two stops among bus stops pertaining to the bus route. The created information is organized to status information that is in turn incorporated into a transfer message. A sequence of transfer messages, each being constructed as described above, is wirelessly transmitted.
