Abstract
A method for generating a track file that contains notification information includes obtaining a raw track file and a road network data, determining whether each of consecutive two of recorded locations of the track file is on or off road segments of the road network data, generating a notification of change in road status when the consecutive two of the recorded locations are determined to be respectively on and off the road segments, calculating an included angle between two line segments which connect in sequence consecutive three of the recorded locations, determining whether the included angle is greater than a threshold value, and generating a notification of turning when the included angle is determined to be greater than the threshold value.
