Method for Sensing Covering State According to Velocity and System for Providing Traffic Information Using the Same Method

Abstract

Disclosed is a method for sensing a traveling state based on a speed. The method for sensing the traveling state based on the speed includes outputting 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, and measuring 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.

         18 . A system for guiding a path, the system comprising:
 a storage unit configured to:
 store road map data and path guide data related to the road map data; 
   a controller configured to:
 ascertain a current position of a vehicle using Global Positioning System (GPS) signals received via a GPS receiver, and the path searching unit configured to search for a path from the current position to a destination using the road map data in the storage unit; 
 provide a path guide based on the path; 
 request for speed information of each link to another device, the link indicating a unit section on a road map related to the path, and 
 receive the speed information from the another device; 
 measure a current speed for each link, compare the current speed with the speed information and determine a current traveling state of the vehicle; and 
   a display unit configured to:
 display the determined traveling state of the vehicle. 
   
     
     
         19 . The system of  claim 18 , wherein the controller further configured to collect a link speed from a user terminal.
