Method for inferring type of road segment

Abstract

Present invention provides a method for inferring the 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 the road network; merging the statistical features with the topological features of the target road segment, and obtaining an arrogated feature vector of the target road segment; building a logistic regression model according to the arrogated feature vector, and obtaining a first inferred type of the target road segment. The present embodiment considers both the driving trajectory data of a plurality of vehicles and the topological structure data of the road network, the accuracy of the present invention is high, and the inferred result is accurate.
