The invention discloses a heuristic rule-based vehicle lane changing track identification method, which comprises the following steps of: sorting original track data according to global time, and judging whether an original data set separately records observation data in different time periods or not; classifying and storing the original data set according to different recording time periods; carrying out smoothing processing on the track coordinate information in the data set; identifying a changing track by using a heuristic track, and obtaining a starting point and an ending point of a track changing action; and carrying out final lane changing model five-vehicle data matching, and completing calculation of high-order data. According to data features of a common vehicle track data set, details and rules of various aspects extracted by vehicle lane changing track recognition are detailed, data support is provided for a subsequent model algorithm based on lane changing behavior details, and a foundation is laid for innovative development of a lane changing model.
