Claim 0:
1. A computer-implemented method for tracking the route trajectory of a traveling object comprising:
obtaining positioning data from a positioning device carried on a traveling object traveling on an overall route including a first route segment in a first direction, a second route segment in a second direction, the second route segment being different from the first route segment;
mapping the positioning data into a plurality of points on a digital map, the digital map including a stored route trajectory of the overall route along the first route segment and the second route segment;
identifying points of the plurality of points on the digital map that are unmatched to the stored route trajectory of the overall route along the first route segment and the second route segment;
obtaining candidate transition points corresponding to the traveling object travelling on a third route segment transitioning between the first route segment and the second route segment from the plurality of unmatched points on the digital map, the candidate transition points being between the first and second route segments and in directions different from the first and second directions;
aggregating the plurality of candidate transition points by applying a clustering algorithm;
classifying a first cluster of points from the aggregated cluster of points as being transition points corresponding to the traveling object travelling on the third route segment transitioning between the first route segment and the second route segment based on a confidence level being above a first threshold; and
automatically adjusting the stored route trajectory of the overall route based on the classification of the first cluster of points as transition points corresponding to the traveling object travelling on the third route segment transitioning between the first route segment and the second route segment.
