METHOD OF PROVIDING DIRECTION INFORMATION ACCORDING TO REAL-TIME TRAFFIC CONDITIONS
First Claim
1. A method of providing direction information in real time, the method comprising:
- receiving path directions request information from a terminal;
generating direction information corresponding to the path directions request information;
transmitting the generated direction information to the terminal;
receiving path directions re-searching request information including remaining path directions; and
re-computing the path directions based on traffic condition reports according to the path directions re-searching request information, and if the re-computed path directions are different from the remaining path directions, re-generating direction information and transmitting the re-generated direction information to the terminal.

Abstract
A method, device and recorded medium having recorded the method, for providing directions information applied with real-time traffic condition reports are disclosed. An aspect of the present invention features a method and device that can receive traffic condition reports in real-time and provide directions information applied with the pertinent traffic condition reports. Accordingly, with the present invention, the directions information can be generated by using first real-time traffic condition reports. Then, the path directions applied with the change of traffic condition reports according to the time flow can be acquired and provided to a user.
