Abstract

A method and apparatus for collecting traffic data in real time are disclosed. When a mobile terminal having received real time traffic data generates a position registration message including the real time traffic data, and then transmits the generated position registration message, a regional traffic server, which manages regional traffic information within a predetermined area, receives the position registration message, and extracts the traffic data from the position registration message. Further, the regional traffic server stores the extracted traffic data in a regional traffic information management database, and then transmits regional traffic information to a central traffic server, thereby enabling the central traffic server to synthetically manage national traffic information. Because messages transmitted/received when a mobile terminal of a mobile communication system, which has been already installed and spread, registers its position, are utilized, the initial investment cost and maintenance cost for collecting traffic data in real time are minimized. Further, because traffic data of corresponding positions from an unspecified plurality of mobile terminals cooperating with a navigation terminal are collected, traffic data can be collected more accurately in real time.
