Vehicle-to-everything (V2X) is communication between a vehicle and any entity that may affect, or may be affected by, the vehicle. It is a vehicular communication system that incorporates other more specific types of communication as V2I (vehicle-to-infrastructure), V2N (vehicle-to-network), V2V (vehicle-to-vehicle), V2P (vehicle-to-pedestrian), V2D (vehicle-to-device).

V2X can be grouped into two supergroups, V2X using common communication technologies like bluetooth or mobile networks and V2X using a dedicated special communication technology. The main motivations for the dedicated V2X technology are road safety, traffic efficiency, energy savings, and mass surveillance. The U.S. NHTSA estimates a minimum of 13% reduction in traffic accidents if a V2V system were implemented, resulting in 439,000 fewer crashes per year. Equally, V2X technology is already used in countries such as China, where different safety information is being communicated between vehicles to reduce road accidents. There are two standards for dedicated V2X communication depending on the underlying technology being used: (1) WLAN-based, and (2) cellular-based.

In the present book, ten typical literatures about Vehicle-to-everything (V2X) published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Vehicle-to-everything (V2X). We hope this book can demonstrate advances in Vehicle-to-everything (V2X) as well as give references to the researchers, students and other related people.
