Using Feature Interaction among GPS Data for Road Intersection Detection

Abstract

Road intersection plays a vital role in road network construction, automatic drive, and intelligent transportation systems. Most methods detect road intersections only using geometrical features without spatio-temporal features, leading to insufficient precision. In addition, the existing methods do not consider the impact of feature interaction. For the issue, this paper proposes a novel way to detect road intersections based on GPS trajectory by extracting spatio-temporal features and using the interaction of the features to enhance the precision of the detection. The proposed method is implemented on DIDI's GPS data in Chengdu. The performance shows that the proposed method can effectively improve the precision of road intersection detection compared with the existing method, which is beneficial for road network construction and makes up for the deficiency of existing methods.
