The sparse problem of traffic volume data is unavoidable due to budget limits and device malfunctions in traffic systems. To address this problem, we propose a license plate recognition (LPR) data and collaborative tensor decomposition (CTD)-based method to estimate the sparse traffic volume data. The method works in two phases: first, a vehicle-time matrix is created based on LPR data, and non-negative matrix factorization is employed to analyze vehicle types; second, a road traffic volume tensor and the corresponding matrix of vehicle types are created, and people’s check-in data and point of interest information are introduced to complement the sparse tensor with CTD. Experimental results show that our method outperforms traditional estimation methods, and it can estimate traffic volume data even when the missing rate is high.
