PURPOSE: A system for collecting traffic information is provided to collect traffic information including the occupancy, the speed, and the lengths of vehicles by analyzing a sensor outputted signal from a sensor node embedded in traffic roads. CONSTITUTION: A sensor node(110) includes a multi sensor module including a terrestrial magnet for detecting vehicles, and a sensor communication module-A. The sensor communication module-A transmits a sensor outputted signal for vehicles which is detected by the multi sensor module. A gateway(120) includes a sensor communication module-B and a complex wireless communication module. The sensor communication module-B receives the sensor outputted signal. A main server(130) includes a wireless communication module receiving effective data, and an outputting unit. The outputting unit displays traffic information on a screen. |
