How does V2X technology work?

Vehicles can “talk” with the road and other vehicles by using the V2X technology which stands for Vehicle-to-Everything. V2X allows vehicles to exchange data in real time with other vehicles and the road infrastructure.

Vehicles connected to an automatic traffic control system are provided with up-to-date information about all incidents occurring on their route. This enables drivers to better navigate through traffic, which increases traffic safety, reduces the road occupancy, and decreases the number and severity of accidents. Additionally, the development and expansion of V2X technology creates the technological and infrastructural basis required for the safe and comfortable traffic of autonomous vehicles.

What opportunities does V2X offer?

First of all, V2X informs drivers about the possible risk of collisions, traffic jams, roadworks, and other obstacles on the road, including about pedestrians and foreign objects on the road.

Also, the technology is able to manage a mixed traffic stream consisting of vehicles with or without V2X equipment, including managing a column of heavy vehicles, such as trucks or road sweepers. For autonomous vehicles, commands for maneuvering or stopping can be given.

This technology enables the high-priority passage of emergency services (ambulances, fire trucks, police cars, and emergency responders) and public transportation. When necessary, it chooses optimal routes to reduce travel time.

How it works?

A wireless on-board unit (OBU) is installed in the vehicle, which receives information on various incidents and maneuvering commands (in case of an autonomous vehicle). Additionally, OBU transfers information about the condition of the vehicle to a traffic control center.

The roadside units (RSUs) link the traffic control system and the vehicles. RSUs are an element of the road infrastructure and are put, for example, on light poles along the road thus forming a network which connects all vehicles that have OBUs.

V2X in Russia

V2X technology is actively being developed in Russia. In July 2022, Telematika Corporation tested a Russian V2X OBU (developed by M-Telematika, a part of Telematika Corporation) on the Central Ring Road (CRR). Today, CRR is not only the most technologically advanced highway in Russia, but it is also unique thanks to the next-generation automatic traffic control system installed by Telematika on the PK-3 section of CRR and the V2X technology for the interaction with connected and autonomous vehicles.

This case is the first tryout of Russian V2X equipment on public roads in Russia. The experiment tested the system in various situations, including accidents, detecting people on the road, traffic jams, roadworks, poor visibility, and slippery roads (a total of 14 scenarios).

The V2X OBU was officially certified and all required conformity certificates were obtained, which permits using the OBU on public roads. It employs the dedicated short-range communications (DSRC) technology, which is optimal for vehicles in motion. This ensures a practically instant connection and data transfer at high speeds up to 250 kmh. In addition, this standard is more resistant to cyber-attacks and guarantees a stable communication.

The national project Safe Quality Roads will help promote the widespread implementing of V2X in Russia. As part of this project, intelligent transport systems are being installed in big cities with a population of 300 thousand and more. The project provides for the stage-by-stage outfitting with intelligent elements, including creating traffic control centers for vehicles and public transportation, monitoring traffic flows, weather monitoring, priority-passage, etc.

To achieve the maximum 5th level (full maturity), the city needs a well-functioning V2X system.

It is envisaged to have intelligent transport systems operating in 82 city agglomerations. These cities will be the ones to first develop V2X technology that can be linked to other systems, such as Safe City and municipal housing and utilities systems. This enables creating a unified smart city system, which will be controlled and exchange information with the system from various domains, such as transportation, infrastructure, municipal housing and utilities, safety, and healthcare.
