Vehicle 5G: Revolutionising road safety?

One of the most promising developments in future mobility is Vehicle-to-Vehicle (V2V) communication via 5G networks.  

By leveraging these networks, the automotive industry is undoubtedly undergoing a transformative shift towards greater connectivity and intelligent automated systems. The technology holds immense potential to revolutionise road safety and enhance the overall driving experience. 

V2V communication refers to the exchange of information between vehicles in real time. Through this technology, vehicles will communicate with each other, constantly sharing data about their position, speed, direction, and other relevant parameters. This information is then processed, and actions determined, ultimately improving road safety by preventing collisions and optimising traffic flows. 

At the heart of V2V communication is the 5G network. Compared to its predecessor, 5G boasts significantly faster speeds, lower latency, and increased bandwidth – meaning a greater volume of devices are able to communicate at a much faster rate. 

V2V communication enables vehicles to exchange data regarding their position and speed, using this to predict intentions and act in tandem to achieve the most efficient and safe outcome. This information is used to determine potential hazards, such as sudden braking or lane changes, allowing vehicles to proactively respond and avoid possible collisions. This technology, combined with smart infrastructure has the potential to save countless lives on the road. According to Kia, “Autonomous vehicles can be trained to be safer than human-controlled cars. With sensors and cameras, they can enhance the safety of a driver as well as pedestrians by eliminating human error.” 

Sharing real-time traffic information, V2V communication helps to optimise traffic flows reducing congestion. Vehicles will collectively adjust their speed and routes based on the shared data, minimising delays and improving overall transport efficiency.  

Commutes become smoother, benefiting both individuals and the environment through reduced fuel consumption and emissions. 

Leveraging V2V communication, adaptive cruise control systems can synchronise with nearby vehicles. This feature further enables a smooth and coordinated flow of traffic, again reducing the risk of disruption whilst enhancing fuel efficiency. 

While V2V communication over the 5G network holds immense promise, its widespread implementation faces a few challenges. These include ensuring standardised protocols, addressing cybersecurity concerns, and establishing robust maintenance and infrastructure. However, ongoing research, collaboration between industry stakeholders, and regulatory support are steadily overcoming these hurdles. 

5G currently stands as a battleground between mobile phone operators and manufacturers, and vehicle manufacturers. Phones are now ubiquitous – especially in Western society – so a debate is fuelled by how much control should be relinquished to the driver’s phone: when driving, will V2V communication come from the vehicle or the mobile phone? 

Looking ahead, the future of V2V communication is bright. As 5G networks continue to expand and mature, we can anticipate further advancements and refinements in V2V systems. Additionally, the integration of V2V communication with emerging technologies like autonomous vehicles and smart city infrastructure will unlock unprecedented possibilities for safer, more efficient transportation. 

Vehicle-to-Vehicle communication facilitated by the 5G network is poised to revolutionise road safety and transform the way we navigate our streets. By enabling seamless data exchange between vehicles, V2V communication looks to enhance safety, optimise traffic flow and pave the way for a smarter, more connected transportation ecosystem.  

As this technology continues to evolve, we can anticipate a future where accidents are minimised, traffic congestion is reduced, and the joy of driving is seamlessly intertwined with cutting-edge connectivity.
