FedTSE: Low-Cost Federated Learning for Privacy-Preserved Traffic State Estimation in IoV
Abstract
Traffic state estimation (TSE) is an important aspect of the Internet of Vehicles (IoV) for road path planning and better driving experience. In IoV, with the support of edge intelligence, real-time traffic data can be processed by edge computing (EC) servers for informed decision-making. However, collecting trajectory information from vehicles in a centralized manner may increase transmission delay and cause driver privacy leakage problems. In this paper, we firstly propose a federated learning (FL) framework for TSE, named FedTSE, with privacy preservation by jointly considering TSE accuracy, model computation, and transmission cost. Then, a TSE model is designed based on the long short-term memory (LSTM) as the local training model for joint prediction of vehicular speed and traffic flow. Considering the resource limitation of computation/communication, we further propose a deep reinforcement learning (DRL)-based algorithm for model parameter uploading/downloading decisions to improve the estimation accuracy of local models and balance the tradeoff between computation and communication cost. Simulation results show the proposed FedTSE achieves a lower cost and higher prediction training accuracy in TSE.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
