Abstract
In this paper, we proposed a vehicle travel trajectory completion algorithm based on license plate recognition data. Firstly, a processing method for redundant license plate data is proposed. Secondly, the abnormal travel trajectory is extracted based on the travel time threshold between adjacent nodes. Then, the alternative trajectory was obtained through the K shortest path algorithm. The combined algorithm of AHP and EWM was used to calculate the weight of multi- objective attribute indexes. The Hierarchical-Entropy-TOPSIS method for determining vehicle travel trajectory was constructed to complete vehicle travel trajectory decision-making. Finally, the reliability of the algorithm is verified by the license plate data of Yicheng County, Linfen City.
