RLOMM: An Efficient and Robust Online Map Matching Framework with Reinforcement Learning
Summary: Online map matching framed as an Online MDP for efficient, incremental fusion of historical and streaming data. RL with a novel learning process and reward design, graph/RNN encodings for trajectory–road heterogeneity, and contrastive learning to align latent spaces, achieving state-of-the-art accuracy, speed, and robustness on three real datasets.
