Safe Connected Cars, Let V2V make our roads safer

The most advanced competent drivers are always alert of vehicles braking, vehicles that are maybe 3 or 4 vehicles ahead of them, thus requiring constant focus and concentration. This can be very difficult and sometimes impossible in an age where the Internet of Things dominates and distracts. There are many distractions such as digital bill boards, advertisements and mobile devices. Having a heated conversation or eating, can at times be troublesome!

WHO - Main causes of death and injury
WHO Report – The main causes of death and injury in 1990 and predicted for the year 2020

The World Health Organisations (WHO) has reported that road traffic injuries cause an estimated 1.2 million fatalities each year. This number will continue to rise at an alarming rate if preventative measure are not taken place, road death is likely to become the third leading cause of death in 2020 from nine place in 1990.

Vehicle 2 Vehicles Communications

Now imagine a world where vehicles can communicate with one another out of sight, out of line and provide real-time feedback on braking, obstacles, danger areas, collisions and even traffic signals. This data will then allow the vehicle to either alert the driver or automatically ‘react’ to the hazard, by either slowing down or alerting other drivers. Imagine driving on a country side road with unseen hazards bought up on your heads-up display or as you approach a school or a village your vehicle automatically reduces its speed.


Vehicle 2 Vehicle (V2V) is a vehicular network that allows out of sight communication with other vehicles. V2V uses Dedicated Short-Range Communications (DSRC), typically 5.9GHz with a bandwidth of 75MHz. DSRC allows a communications distance of up-to 1600m out of sight communications. This technology allows the vehicles to effectively ‘view’ and ‘survey’ the surroundings around them. Now let’s be honest, even the best of drivers can’t see around corners!

The Internet Of Cars

Ideally the next stage along with V2V communications would be to create a vehicle infrastructure network (V2I) connecting traffic signals, traffic cameras, vehicles, emergency services, motorway infrastructure, the cloud and virtually anything, providing us with a constant feed of data that we can use not only to ensure safer travel and reduce the number of road traffic accidents but also to plan and organise our daily lives. Imagine getting into your vehicle as it informs you of the weather, your schedule and even re-routing you from the data it’s receiving from the V2V network, truly innovative concept that’s amazes me.

Some of the benefits and uses that V2V and V2I would bring include:

  • Safety – Allows instant notification of unseen hazards, for example, emergency vehicles approaching, driving in extreme weather with zero visibility, such as fog, snow and rain etc.
  • IoT, Internet of Cars – Imagine getting into your vehicle as it informs you of the weather, your schedule and even re-routing you from the data it’s receiving from the V2V network, truly amazing.
  • Congestion and Policing – Allows vehicles to travel at safe distances, reducing congestion and improving safety. Policing around airports and key buildings allows restrictions to be placed on speed and parking.
  • Speed & Parking – Automatic speed correction and parking notices and restrictions will be displayed, giving the driver options and re-routing if need be.

V2V in the future

This technology will be implemented in many areas not only vehicles but bikes, motorcycles and light aircraft. The list is endless and I feel this technology will advance further and within the next 10 years be part of our transport infrastructure making our surroundings and roads efficient and safer. What if you have a great desire to install V2V in your existing vehicle ?, not to worry, according to the NHTSA, by the year 2020, the approximate cost of implementing V2V technology per vehicle would be between $350 making it affordable for everyone.


Many vehicle manufacturers such as BMW, FORD, AUDI and others have begun implementing basic crash avoidance technology into their vehicles. V2V is however yet to be implemented and is an exciting innovative concept, so the next time you’re buying a vehicle, take V2V communications into consideration, why not make your driving experience a more safer one and always remember, even the best of drivers cannot see around corners!
