Patent ID: 8290694

Claim:
A method for sensing by a user terminal a traveling state based on a speed, the method comprising: outputting by the user terminal a mean speed C for each link with respect to a number of total traversing times of a predetermined path, and updating a reference speed B with the outputted mean speed C; measuring by the user terminal a speed A while traversing the predetermined path, and comparing the measured speed A with the updated reference speed B, thereby displaying the traveling state; wherein the outputting by the user terminal of the mean speed C includes: determining by the user terminal in advance a path frequently used by a user; measuring by the user terminal a speed A for each link for each time the predetermine predetermined path is traversed; outputting by the user terminal the mean speed C of the measured speed A with respect to the number of total traversing times of the predetermined path; storing by the user terminal the measured speed A each time the predetermined path is traversed; and outputting by the user terminal the mean speed C of remaining speeds excluding a maximum speed and a minimum speed from among the stored speeds A.
