Research on Traffic Data Recovery Based on Tensor Filling and Tensor Matrix Association Analysis

摘要

Traffic data is the data foundation for smart transportation construction. However, due to inclement weather and equipment damage, there are often data missing during the collection of traffic data, which severely restricts smart transportation construction progress. Therefore, traffic data recovery has become an urgent problem in the field of intelligent transportation. Aiming at the problem that the recovery accuracy of existing traffic data recovery methods declines sharply under extreme missing conditions, this paper proposes a traffic data recovery model based on tensor filling and tensor matrix association analysis. The experimental results combined with real taxi GPS positioning data and point of interesting (POI) data of Kunming show that the traffic data recovery model proposed in this paper can significantly improve the recovery accuracy of missing data and maintain good stability in the case of extreme data missing.
