Hybrid Car-Following Model with LSTM and RF in Driver Behavior
摘要
Urban traffic congestion severely restricts lane change and overtaking opportunities, making the study of car follower behavior essential for improving traffic flow and safety. This research leverages large-scale vehicle trajectory data and machine learning techniques to develop high-precision vehicle follow-up models tailored to different driving styles. A data set of 100 vehicle trajectories is preprocessed using double exponential smoothing to mitigate measurement noise. While traditional models like IDM [1] and Gipps’ model [2] have laid foundational principles, their reliance on instantaneous parameters limits adaptability to dynamic scenarios. Recent advancements in hybrid machine learning architectures [3, 4] and deep temporal models [5, 6] offer promising solutions. This research leverages these innovations to develop a hybrid LSTM-RF framework, combining the robustness of ensemble learning [7] with the sequential modeling power of LSTM [8].
