Overtaking Rule Method for the Cleaning of Matched License-Plate Data

摘要: In recent years automatic number plate recognition systems have been increasingly used to monitor urban link travel time. However, the set of times produced will contain erroneous records for a variety reasons including misreading licence plates by camera, vehicles stopping en-route, and taking nondirect routes between two camera sites. This paper proposes novel technique called overtaking rule, which uses serial temporal structure data filter out these time records. The methodology measure performance cleaning method, it is subsequently shown that rule outperforms existing methods.
