TY - JOUR PY - 2015// TI - Traffic speed data imputation method based on tensor completion JO - Computational intelligence and neuroscience A1 - Ran, Bin A1 - Tan, Huachun A1 - Feng, Jianshuai A1 - Liu, Yunbo A1 - Wang, Wuhong SP - 364089 EP - 364089 VL - 2015 IS - N2 - Traffic speed data plays a key role in Intelligent Transportation Systems (ITS); however, missing traffic data would affect the performance of ITS as well as Advanced Traveler Information Systems (ATIS). In this paper, we handle this issue by a novel tensor-based imputation approach. Specifically, tensor pattern is adopted for modeling traffic speed data and then High accurate Low Rank Tensor Completion (HaLRTC), an efficient tensor completion method, is employed to estimate the missing traffic speed data. This proposed method is able to recover missing entries from given entries, which may be noisy, considering severe fluctuation of traffic speed data compared with traffic volume. The proposed method is evaluated on Performance Measurement System (PeMS) database, and the experimental results show the superiority of the proposed approach over state-of-the-art baseline approaches.
