Abstract

A traffic information management method and apparatus is provided. The traffic information management method using light communication includes: receiving an optical signal transmitted from a signal system; acquiring traffic information contained in the light signal; and providing the traffic information to a user terminal.

Claims

1. A traffic information management method using light communication, comprising:

receiving an optical signal transmitted from a signal system;

acquiring traffic information contained in the light signal; and

providing the traffic information to a user terminal.

2. The traffic information management method of claim 1, further comprising:

generating vehicle control information using the traffic information; and

providing the vehicle control information to a vehicle.

3. The traffic information management method of claim 2, wherein the vehicle control information comprises economical speed information for economical driving of the vehicle.

4. The traffic information management method of claim 2, wherein said generating vehicle control information using the traffic information comprises:

when the optical signal is a stop signal, acquiring duration information of the stop signal contained in the traffic information; and

generating the vehicle control information containing an engine control command by using the duration information of the stop signal.

5. The traffic information management method of claim 2, wherein said generating vehicle control information using the traffic information comprises:

when the optical signal is a preliminary signal, determining whether to accelerate or stop the vehicle; and

generating the vehicle control information containing an acceleration command or stop command, depending on the result of said determining whether to accelerate or stop the vehicle.

6. A traffic information management apparatus using light communication, comprising:

a reception unit configured to receive an optical signal transmitted from a signal system;

a control unit configured to acquire traffic information contained in the optical signal; and

a transmission unit configured to provide the traffic information to a user terminal.

7. The traffic information management apparatus of claim 6, wherein the control unit generates vehicle control information using the traffic information, and the reception unit provides the vehicle control information to a vehicle.

8. The traffic information management apparatus of claim 7, wherein the vehicle control information comprises economical speed information for economical driving of the vehicle.

9. The traffic information management apparatus of claim 7, wherein the control unit acquires duration information of the stop signal contained in the traffic information when the optical signal is a stop signal, and generates vehicle control information containing an engine control command by using the duration information of the stop signal.

10. The traffic information management apparatus of claim 7, wherein the control unit determines whether to accelerate or stop the vehicle when the optical signal is a preliminary signal, and generates vehicle control information containing an acceleration command or stop command depending on the determination result.
