Apparatus and method for collecting traffic information using ultra wideband impulse, and system and method for controlling traffic sign using the same
First Claim
1. An apparatus for collecting/managing traffic information by using ultra wideband impulse, comprising:
- a primary wireless communication means for assigning channels upon 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 a ultra wideband impulse response signal which is transmitted from the terminal installed in the vehicle and ultra wideband impulse response signals which are transmitted from a plurality of secondary wireless communication means, and transmitting the computed traffic information to a traffic control server;
the multiple number of secondary wireless communication means for transmitting the ultra wideband impulse response signals, which are transmitted from the terminal installed in the vehicle, to the primary wireless communication means; and
the traffic control server for managing the traffic information transmitted from the primary wireless communication means in a database so that the traffic information can be applied to traffic-related systems.

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.
