Vehicle-to-everything (V2X) is a communication technology that allows vehicles to connect and share information with various entities, including other vehicles, infrastructure, and even pedestrians. This technology enhances road safety, traffic efficiency, and overall driving experience by enabling real-time data exchange. V2X encompasses several types of communication, such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P). By facilitating these interactions, V2X can help reduce accidents, improve traffic flow, and support the development of smart cities, ultimately leading to a more connected and efficient transportation system.
