Abstract: Provided are a traffic information collecting/managing apparatus using ultra wideband impulse, a method thereof, a traffic light control system using the method and a method therefor. The traffic information collecting/managing apparatus includes: a primary wireless communication unit for assigning channels upon receipt of a channel assignment request from a terminal installed in a vehicle, computing location information and speed information, which will be referred to as traffic information, based on time by using ultra wideband impulse response signals transmitted from the terminal and a plurality of secondary wireless communication means, and Transmitting the traffic information to a traffic control server, the wireless communication means for transmitting the ultra wideband impulse response signals transmitted from the terminal to the primary wireless communication unit; and the traffic control server for managing the traffic information transmitted from the primary wireless communication unit in a database so that the traffic information can be applied to traffic-related systems.
