Abstract

The present invention relates to a system for providing real-time traffic information using a wireless network and a method thereof, particularly a system for providing real-time traffic information using a wireless network, by using a wireless network technology for preventing a traffic accident and an accident due to traffic congestion, and a method of providing real-time traffic information using a wireless network. A system for providing real-time traffic information using a wireless network according to an embodiment of the present invention includes: one or more vehicle velocity information collectors that are disposed on a road to establish a wireless network for sharing information, and collect vehicle velocity information of vehicles on the road; and a traffic information provider that receives the vehicle velocity information from the one or more vehicle velocity information collectors and provides a traffic information based on the vehicle velocity information.

Claims

1. A system for providing real-time traffic information, comprising:

one or more vehicle velocity information collectors that are disposed on a road to establish a wireless network for sharing information, collect vehicle velocity information of vehicles on the road, and correlate the vehicle velocity information; and

one or more traffic information provider that receives the correlated vehicle velocity information from the one or more vehicle velocity information collectors and provides a traffic information that is determined based on the correlated vehicle velocity information.

2. The system for providing real-time traffic information according to claim 1, further comprising:

a vehicle velocity information generator that is equipped in the vehicle to generate vehicle velocity information, and outputs the generated vehicle velocity information to the vehicle velocity information collectors.

3. The system for providing real-time traffic information according to claim 1, wherein the vehicle velocity information collector includes a sensor that measures the velocity of a vehicle positioned at a predetermined area of the road.

4. The system for providing real-time traffic information according to claim 1, wherein when the collected vehicle velocity information exceeds a predetermined velocity, the vehicle velocity information collector excludes corresponding vehicle velocity information.

5. The system for providing real-time traffic information according to claim 1, wherein the one or more traffic information provider classify the vehicle velocity information transmitted from the vehicle velocity information collectors for each collection position, and determine whether a traffic accident and traffic congestion occur at each area.

6. The system for providing real-time traffic information according to claim 1, further comprising:

a traffic information management server that checks the entire traffic condition of the road by receiving traffic information from the traffic information providers, and provides the traffic information to the traffic information providers.

7. The system for providing real-time traffic information according to claim 2, wherein when the generated vehicle velocity information exceeds a predetermined velocity, the vehicle velocity information generator excludes output of corresponding vehicle velocity information.

8. A method of providing real-time traffic information, comprising:

collecting vehicle velocity information of vehicles on a road, using one or more vehicle velocity information collectors that are disposed on the road to establish a wireless network for sharing information; and

providing traffic information by checking a traffic information condition on the basis of vehicle velocity information shared and transmitted by the vehicle velocity information collectors, using a traffic information provider.

9. The method of providing real-time traffic information according to claim 8, further comprising:

generating vehicle velocity information, by using a vehicle velocity information generator equipped in a vehicle, and outputting the generated vehicle velocity information to the vehicle velocity information collectors.

10. The method of providing real-time traffic information according to claim 8, wherein the outputting of the generated vehicle velocity information excludes corresponding vehicle velocity information, when the collected vehicle velocity information exceeds a predetermined vehicle velocity.

11. The method of providing real-time traffic information according to claim 8, wherein the providing of traffic information classifies the vehicle velocity information transmitted from the vehicle velocity information collectors for each collection position, and determines whether a traffic accident and traffic congestion occur at each area.

12. A method of providing real-time traffic information using a wireless network, comprising:

collecting vehicle velocity information of vehicles on a road, using one or more vehicle velocity information collectors that are disposed on the road to establish a wireless network for sharing information;

providing traffic information by checking a traffic information condition on the basis of vehicle velocity information shared and transmitted by the vehicle velocity information collectors, using one or more traffic information providers; and

checking the entire traffic condition of the road by receiving traffic information from the traffic information providers, and providing the traffic information to the traffic information providers, using a traffic information management server.

13. The method of providing real-time traffic information according to claim 12, further comprising:

generating vehicle velocity information, by using a vehicle velocity information generator equipped in a vehicle, and outputting the generated vehicle velocity information to the vehicle velocity information collectors.

14. The method of providing real-time traffic information according to claim 12, wherein the outputting of the generated vehicle velocity information excludes corresponding vehicle velocity information, when the collected vehicle velocity information exceeds a predetermined vehicle velocity.

15. The method of providing real-time traffic information according to claim 12, wherein the providing of traffic information classifies the vehicle velocity information transmitted from the vehicle velocity information collectors for each collection position, and determines whether a traffic accident and traffic congestion occur at each area.
