V2X (Vehicle-to-Everything) applications refer to the communication between vehicles and other entities such as infrastructure, pedestrians, and other vehicles. This research area focuses on developing technologies and systems that enable vehicles to share real-time information with their surroundings to improve safety, efficiency, and convenience on the roads. Some common V2X applications include vehicle-to-vehicle (V2V) communication for collision avoidance, vehicle-to-infrastructure (V2I) communication for traffic management, and vehicle-to-pedestrian (V2P) communication for pedestrian safety. Researchers in this area work on developing communication protocols, algorithms, and systems to enable seamless and secure communication between vehicles and their surrounding environment. Overall, V2X applications aim to enhance the overall driving experience, reduce traffic congestion, and improve road safety through the use of advanced communication technologies.
