Vehicle-to-everything (V2X) describes wireless communication between a vehicle and any entity that may affect, or may be affected by, the vehicle. Sometimes called C-V2X, it is a vehicular communication system that is intended to improve road safety and traffic efficiency while reducing pollution and saving energy.
IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to add wireless access in vehicular environments (WAVE), a vehicular communication system. It defines enhancements to 802.11 (the basis of products marketed as Wi-Fi ) required to support intelligent transportation systems (ITS) applications.
The science of telecommunications and informatics applied in wireless technologies and computational systems. 802.11p, the IEEE standard in the 802.11 family and also referred to as Wireless Access for the Vehicular Environment (WAVE), is the primary standard that addresses and enhances Intelligent Transport System.
Components of an access control system include: An access control panel (also known as a controller) An access-controlled entry, such as a door, turnstile, parking gate, elevator, or other physical barrier; A reader installed near the entry. (In cases where the exit is also controlled, a second reader is used on the opposite side of the entry.)
In the US, the systems could use a region of the 5.9 GHz band set aside by the United States Congress, the unlicensed frequency also used by Wi-Fi. The US V2V standard, commonly known as WAVE ("Wireless Access for Vehicular Environments"), builds upon the lower-level IEEE 802.11p standard, as early as 2004.
An automated driving system is defined in a proposed amendment to Article 1 of the Vienna Convention on Road Traffic: (ab) "Automated driving system" refers to a vehicle system that uses both hardware and software to exercise dynamic control of a vehicle on a sustained basis.

FCW systems will send an alert to the driver of a possible impending collision if gets too close to the vehicle in front of it. [21] These systems do not take control of the vehicle, as currently, FCW systems only send an alert signal to the driver in the form of an audio alert, visual pop-up display, or other warning alert.
