ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a traffic information servicing method, and more particularly, to a traffic information servicing method for providing traffic information. The present application is based upon Korean Application No. 98-42435, which is incorporated herein by reference.
2. Description of the Related Art
In general, a terminal in a car receives general traffic information from a traffic information providing system. For example, a traffic information providing system such as the VICS (vehicle information and communication system) and the DARC (data radio channel) is not for a specific car, and transmits previously collected traffic information of an unspecific area to an unspecific car by voice and data.
FIG. 1
shows a traffic information service system using a conventional VICS.
A first VICS center
130
of area A and a second VICS center
120
of area B exists in a VICS area
110
. The first VICS center
130
transmits traffic information collected in the area A in the form of data to a car navigation terminal
140
built in a car through a FM broadcast. The car navigation terminal
140
receives the information of the area A through the FM broadcast and can use the received information as visible information.
As mentioned above, the VICS transmits the collected traffic information of the specific area in the form of data to a general user through the FM broadcast. A user who has the system can use the traffic information of the relevant area.
However, only unidirectional communication can be performed in the VICS. Enormous expenses and much installation time are spent on collecting the traffic information, establishing the VICS center, respective terminal manufacturers and VICS center managers, and establishing a VICS data format. It is difficult for a car in the area A to obtain the traffic information of the area B since only the traffic information of the specific area is provided.
SUMMARY OF THE INVENTION
It is an objective of the present invention to provide a traffic information servicing method for conveniently receiving desired traffic information by a user by transmitting and receiving data between a navigation device installed in a car and an information center.
Accordingly, to achieve the above objective, there is provided a traffic information servicing method including a car navigation device communicating with an information center for providing traffic information according to received car information, a radio telephone, and an adaptor for controlling the radio telephone comprising transmitting the car information from the car navigation device to the information center; analyzing the car information received from the car navigation device; determining a predetermined number and order of map areas corresponding to the analyzed car information; and transmitting the predetermined number and order of map areas as traffic information to the car navigation device.
