Intersection decision making for autonomous vehicles based on improved PPO algorithm
IET Intelligent Transport Systems, Volume 18, Issue S1, Page 2921-2938, December 2024.In this article, we improve the proximal policy optimisation (PPO) algorithm in deep reinforcement learning and propose an MSA‐PPO algorithm, which adopts the self‐attention mechanism for input data processing, effectively identifies and focuses on the most important information in the interaction between vehicles to improve the overall performance of ...

Evaluation of automated driving safety in urban mixed traffic environments
IET Intelligent Transport Systems, Volume 18, Issue S1, Page 2963-2976, December 2024.The research process consisted of four steps. Step 1: The driving behaviour of an MV following an AV was analysed via DS. Step 2: The driving behaviour of the MVs in each section was implemented by adjusting the parameters of the IDM, a microscopic vehicle following the model.
