The invention provides a trajectory fitting method and device, electronic equipment and a storage medium, and relates to the field of path data processing of traffic management. The trajectory fittingmethod comprises the steps of preprocessing trajectory data of a target vehicle to obtain a to-be-processed trajectory point set; acquiring first road grabbing information of the first track point set according to the road network mapping data of the monitoring area; obtaining a target path combination through which the target vehicle passes according to the first road grabbing information, wherein the target path combination comprises at least one road; and fitting the to-be-processed track point set in the target path combination to obtain a fitting track of the target vehicle in the monitoring area. By using the trajectory fitting method provided by the embodiment of the invention, the dense trajectory points of the vehicle can be removed, and the road network mapping data of the monitoring area can be called, so that the fitting of the vehicle trajectory is realized, and the trajectory fitting efficiency is improved.
