The embodiments of the present application disclose a license plate correction method and apparatus. A to-be-corrected license plate and a corresponding to-be-corrected vehicle-passing record are first determined. Similar license plates of the to-be-corrected license plate are determined. The vehicle-passing record for each similar license plate is matched with the to-be-corrected vehicle-passing record, thereby determining a matching probability of each similar license plate and the to-be-corrected license plate. A similar license plate is determined as a corrected license plate, wherein the matching probability between this similar license plate and the to-be-corrected license plate is highest. Therefore, a license plate that was incorrectly recognized can be corrected.

Method and device for correcting license plate

A speed prediction method and apparatus are disclosed. The method includes: obtaining traffic-effecting parameter information of a first road segment in a current time period (S), wherein the traffic-effecting parameter information comprises at least one of a parameter of the effect of the current weather on the traffic, a parameter of the effect of an attribute of the current date on the traffic and a parameter of the effect of a special event on the traffic; determining a similarity between the traffic-effecting parameter information and historical traffic-effecting parameter information of the first road segment stored in a historical traffic database (S), and determining target historical traffic-effecting parameter information according to the determined similarity (S); and predicting a first speed of a vehicle on the first road segment in the next time period, according to a speed of a vehicle in a next time period of a time period corresponding to the target historical traffic-effecting parameter information, stored in the historical traffic database (S).

Speed prediction method and apparatus

A method and device of processing vehicle passing records, which increase the accuracy of vehicle stop point analysis. The method includes: obtaining a plurality of vehicle passing records of a preset target object during a first preset time period (S), wherein, the vehicle passing records include a gate number of a gate that the preset target object passes and vehicle passing time when passing the gate; obtaining a plurality of vehicle trajectories of the preset target object based on the plurality of vehicle passing records (S); performing stop point pre-processing on the vehicle trajectories to obtain pre-processed results (S); obtaining pre-processed records that meet a first preset condition from the pre-processed results (S); performing clustering processing on the pre-processed records to obtain clustering processing results; outputting the clustering processing results (S).
