Abstract

Provided are a route guidance system and method for emergency vehicle using telematics. The route guidance system includes an instruction station, a vehicle telematics and a traffic signal controller. The instruction station sends destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance. The vehicle telematics is attached to the emergency vehicle, and searches a plurality of travel routes on the basis of the destination information to provide the shortest travel route. The traffic signal controller controls a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.

Claims

1. A route guidance system for an emergency vehicle using telematics, the route guidance system comprising:

an instruction station sending destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance;

a vehicle telematics, which is attached to the emergency vehicle, searching a plurality of travel routes on the basis of the destination information to provide the shortest travel route; and

a traffic signal controller controlling a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.

2. The route guidance system of claim 1, wherein the destination information comprises GPS coordinates for a determination of a corresponding position, a phone number and an address.

3. The route guidance system of claim 1, wherein the travel information comprises moving directions of the emergency vehicle including left turn, straight, and right turn information.

4. The route guidance system of claim 3, wherein the travel information further comprises emergency-vehicle registration information.

5. The route guidance system of claim 1, wherein the vehicle telematics sends the travel information as wireless information or RFID tag information to the traffic signal controller of a corresponding traffic signal.

6. The route guidance system of claim 1, wherein the vehicle telematics searches and sets the shortest travel route according to Transport Protocol Expert Group (TPEG).

7. The route guidance system of claim 6, wherein the vehicle telematics searches again and sets the shortest travel route at a changing point when changing the travel route according to the TPEG.

8. The route guidance system of claim 1, wherein the traffic signal controller controls traffic lights according to whether the travel information comprises emergency-vehicle registration information.

9. A route guidance method for emergency vehicle using telematics, the route guidance method comprising:

checking if destination information comprising a dispatch request for an emergency vehicle is received, or if destination information is inputted from a driver, due to an occurrence of an emergency circumstance;

searching a plurality of travel routes on the basis of the destination information according to Transport Protocol Expert Group (TPEG) to send travel information comprising the shortest travel route when the destination information is received or inputted; and

controlling a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of the travel information.

10. The route guidance method of claim 9, wherein the destination information comprises GPS coordinates for a determination of a corresponding position, a phone number and an address.

11. The route guidance method of claim 9, wherein the travel information comprises moving directions of the emergency vehicle including left turn, straight, and right turn information.

12. The route guidance method of claim 11, wherein the travel information further comprises emergency-vehicle registration information.

13. The route guidance method of claim 9, wherein the sending of the travel information comprises again searching and setting the shortest travel route at a change point when changing the travel route, according to the TPEG.

14. The route guidance method of claim 9, wherein the sending of travel information comprises sending the travel information as wireless information or RFID tag information to a traffic signal controller of a corresponding traffic signal.

15. The route guidance method of claim 9, wherein the controlling of a corresponding traffic signal comprises controlling traffic lights according to whether the travel information comprises emergency-vehicle registration information.
