The invention provides a vehicle track identification method and device, identification equipment and a readable storage medium, and relates to the technical field of vehicle networks, and the method comprises the steps: obtaining first track data corresponding to a target vehicle in a target time period; based on a map matching algorithm of a hidden Markov model, correcting and supplementing the first trajectory data to obtain second trajectory data, the second trajectory data comprising vehicle information and lane information corresponding to at least one trajectory point; obtaining at least one threshold value corresponding to each track point according to the lane speed limit in the lane information corresponding to each track point; according to the vehicle information corresponding to the track point, the lane information and the threshold value, track identification is conducted on the second track data, a target track is obtained, and the target track comprises a turning track and/or a lane changing track. According to the scheme, the problem that the lane changing track and the turning track of the vehicle are difficult to accurately recognize in related technologies is solved.
