The invention discloses a lane-level steering information detection method and device for a plane intersection, and the method comprises the steps: carrying out the preprocessing, track data cleaning and map matching of a road network, and achieving the connection between a track point and an affiliated road section; an intersection guiding area identification step: taking intersection track distribution characteristics and vehicle straight-going stop information at a stop line into consideration, and carrying out intersection guiding area detection; an intersection lane identification step of extracting a track related to the guide area based on an intersection guide area identification result, performing multi-angle denoising, and performing guide area lane derivation according to the multi-angle denoising; and an intersection lane-level steering information detection step of performing transverse and longitudinal statistics on the steering track of each lane in consideration of an intersection lane identification result, and performing intersection lane-level steering information detection by adopting a supervised learning method. According to the method, the intersection lane-level steering information is identified based on the public source trajectory for the first time, and the defect that existing work lacks systematic research in the aspect of lane-level steering information mining is overcome.
