Abstract	Vehicle-to-everything (V2X) communication technology is changing the way we move. It allows vehicles, devices, and infrastructures to interact, overcoming traditional limitations, and enabling smart mobility. V2X technologies aim to enhance road safety, transportation efficiency, energy savings, and driver assistance systems, thus being an important milestone in the development of smart cities. To improve the reliability and efficiency of these technologies, researchers and practitioners are increasingly turning to Deep Reinforcement Learning (DRL). This chapter offers an introduction to DRL in V2X, and its synergy with Federated Learning (FL). It starts by explaining the principles of DRL, where vehicles learn themselves which behavior to follow. A strong focus is put on deep policy gradient and actor-critic methods. These methods are crucial in reinforcement learning and rely on using deep neural networks to find good policies and evaluate them. FL, a collaborative machine learning paradigm that promotes collective learning, is also introduced. The fusion of FL and DRL leads to Federated Deep Reinforcement Learning (FedDRL), offering scalable solutions to modern V2X challenges. Federated Deep Reinforcement Learning (FedDRL) is then applied to the use-case of access point selection for communication in Vehicle-to-Everything (V2X) technologies. These experiments demonstrate the potential of combining Deep Reinforcement Learning (DRL) and Federated Learning (FL) to advance V2X technology. This offers intelligent, adaptable, and collaborative mobility solutions for the future. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
