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).
The main motivations for V2X 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. There are two types of V2X communication technology depending on the underlying technology being used: (1) WLAN-based, and (2) cellular-based.
The V2X contains the following sub categories:
Vehicle-to-Everything (V2X) - "communication between a vehicle and any entity that may affect, or may be affected by, the vehicle."
Vehicle-to-Device (V2D) - Bluetooth / WiFi-Direct, e.g. Apple’s CarPlay and Google’s Android Auto.
Vehicle-to-Grid (V2G) - information exchange with the smart grid to balance loads more efficiently.
Vehicle-to-Building (V2B), also known as Vehicle-to-Home (V2H)
Vehicle-to-Load (V2L)
Vehicle-to-Network (V2N) - communication based on Cellular (3GPP) / 802.11p.
Vehicle-to-Cloud (V2C) - e.g. OTA updates, remote vehicle diagnostics (DoIP).
Vehicle-to-Infrastructure (V2I) - e.g. traffic lights, lane markers and parking meters.
Vehicle-to-Pedestrian (V2P) - e.g. wheelchairs and bicycles.
Vehicle-to-Vehicle (V2V) - real-time data exchange with nearby vehicles.
The history of working on vehicle-to-vehicle communication projects to increase safety, reduce accidents and driver assistance can be traced back to the 1970s with projects such as the US Electronic Road Guidance System (ERGS) and Japan's CACS. Most milestones in the history of vehicle networks originate from the United States, Europe, and Japan.
Standardization of WLAN-based V2X supersedes that of cellular-based V2X systems.

A connected car is a car that can communicate bidirectionally with other systems outside of the car (LAN). This allows the car to share internet access, and hence data, with other devices both inside and outside the vehicle. For safety-critical applications, it is anticipated that cars will also be connected using dedicated short-range communications (DSRC) or cellular radios, operating in the FCC-granted 5.9 GHz band with very low latency. Both the U.S. and EU scenarios concentrate on 5.
An intelligent transportation system (ITS) is an advanced application which aims to provide innovative services relating to different modes of transport and traffic management and enable users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. Some of these technologies include calling for emergency services when an accident occurs, using cameras to enforce traffic laws or signs that mark speed limit changes depending on conditions.
Vehicle sharing systems (VSSs) are becoming increasingly popular, primarily due to their financial and environmental advantages. However, VSSs face many operational challenges, including inventory management of vehicles and parking spots, vehicle load bala ...
