Introduction to the vehicle-to-everything communications service V2X feature in 3GPP release 14

The expectation with an established intelligent transportation system is to avoid traffic congestion and increase overall traffic efficiency. End-to-end digitization, starting from the single vehicle through all elements of the transportation system from road infrastructure to backend server, provides the general basis for continuous control and management of traffic flow. This white paper introduces the V2X feature in release 14 and also details the earlier IEEE 802.11p based intelligent transportation system.
