IoT for traffic safety

Make vehicles talk!

– open systems for the vehicles and the traffic environment of the future.

Communication between individuals is a great advantage for an art in nature, it’s a way to show warning, to inform and protect each other as a group. Together with others we can see challenges, find new solutions and development can excel. We should see this as an obvious way to build the future of vehicle communication, when we together drive the development forward and can reach further when it comes to a safer traffic environment.

For a long time, vehicles have had technique to help the driver avoid or minimize damage during an accident, from seatbelts to ABS and traction control. We trust our vehicles own systems and that they will help us when needed, but now it’s time for vehicles to start talking to others and each other. When vehicles start communicating new opportunities are created. For example, in the event of an accident, your vehicle is informed by the vehicle in front that you must brake, train accidents at crossings can largely be eliminated. The systems can not only warn other vehicles about slippery roads, but also notify others who are responsible for eg. plowing/sanding/salting the roads.

During 2018 Volvo Cars together with Volvo Trucks initiated a collaboration where new cars and trucks will warn each other of dangers, which is good. All the steps we take together to create a safer traffic environment is good but, if we are going to secure our traffic situation, all vehicles must talk to each other and the world around them.

Toyota uses DSRC which basically is Wifi technology, a free standard that is available today and is relatively easy to implement. Ford build their technique with C-V2X which is based on LTE. Creating a standardized system that can talk to each other is a prerequisite for it to work long-term and become a sustainable solution when building future vehicles and cities. We need to make sure that we speak the same language and find ways to both secure and share information which creates opportunities to further develop the technology.

Working together with others to find these standards facilitates implementation both of internal systems and V2V/V2I. We, here at Fältcom, are for example strategic members of ITxPT and work together with Telia and other companies in Europe to create a common standard for ITS systems within public transportation. This makes it easier for our customers to take the step to implement the technology and the pace of innovation increases.

Now that vehicles begin to feel and observe their surroundings to a greater extent, it is everyone's shared responsibility to create systems that contribute to a safer traffic environment. We therefore want to challenge all vehicle manufacturers to open up their APIs so they can integrate and communicate with other devices. And in the long run, this doesn’t only apply to vehicles – a great opportunity is when intelligent infrastructure in the smart city emerges. Already now, in many cities you can get a text message when the bus will arrive. And today, several examples of smart infrastructure are being implemented such as the thinking bus stop in Finland.

We think it is high time that we give everyone's vehicles something to talk about, for the sake of the future.
