1. A method for inferring a type of a road segment, comprising the steps of:

  • collecting historical driving trajectory data of a plurality of vehicles for a target road segment, performing a statistic on the historical driving trajectory data, and obtaining statistical features of the target road segment;

    extracting topological features of the target road segment from topological structure data of a road network in which the target road segment locates ;

    merging the statistical features with the topological features of the target road segment and obtaining an arrogated feature vector of the target road segment; and

    building a logistic regression model according to the arrogated feature vector and obtaining a first inferred type of the target road segment.
