Scandinavian cloud-based project for sharing road-condition information becomes a reality

12 February 2015

Volvo Cars, the Swedish Transport Administration and the Norwegian Public Roads Administration are working together on a project to enable cars to share information about conditions that relate to road friction (such as icy patches).

The information will be shared through a cloud-based network – a revolutionary approach to improving traffic safety. And with the test fleet now expanding from about 50 cars to 1000, the project is moving rapidly towards its goal of making the technology available to customers within a few years’ time.

“The more information that can be shared on the road, the fewer surprises there are. And when you’re driving, surprises are what you most want to avoid,” says Erik Israelsson, Project Leader Cooperative ITS (Intelligent Transport System) at Volvo Cars.

“In light of that, we’ve developed a slippery-road alert, which notifies drivers about icy patches and contributes to making winter road maintenance more efficient. We’re also adding a hazard-light alert, which will tell drivers if another vehicle in the area has its hazard lights on. With these first two features, we have a great platform for developing additional safety features. This is just the beginning,” Erik Israelsson continues.

Project nears completion
And the research project is getting closer to real-world implementation: with the technology in place, the testing and validation phase is now about to begin. In this phase, Volvo Cars will both expand the test fleet 20-fold and broaden the test area to include two big Scandinavian cities: Gothenburg and Oslo. Together, these measures will provide a more complete picture of how the system will work in real winter traffic conditions.

Improved winter road maintenance
The slippery-road alert also sends information about icy patches to road administrators as a complement to existing measurement stations along the road. The data can help road administrators and their contracted entrepreneurs to better plan and execute winter road maintenance and quickly address changed conditions. In addition, the Norwegian Public Roads Administration will conduct an independent assessment of the system to identify additional uses for the data in aiding future winter road maintenance.

Ambitious connectivity strategy
Volvo Cars strategically invests in and initiates partnerships to create cloud-based solutions. The hazard-light and slippery-road alerts are the first safety features in the Volvo cloud. The development of sophisticated communication via the mobile network is part of the company’s aim to offer customers a fully connected experience.

“In the future we will have increased the exchange of vital information between vehicles, as well as between vehicles and infrastructure,” says Erik Israelsson. “There is considerable potential in this area, including safer traffic, a more comfortable drive and improved traffic flow,” he adds.

“This will bring us closer to our safety vision that by 2020 no one should be killed or seriously injured in a new Volvo car. And it’s another way in which the ‘Designed around you’ philosophy improves the driving experience,” concludes Erik Israelsson.

Slippery road warning shared with other cars
Volvo Cars is joining forces with road administrators in a pilot project in which road friction information from individual cars is shared within a cloud-based system. When the test car detects an icy or slippery road patch, the information is relayed via Volvo Cars’ database to other vehicles that are approaching the slippery area. The information is also sent to the road administrator. This helps the administrator and contracted entrepreneurs to quickly address changed conditions.

Car2Car communication
Enabling vehicles to communicate with each other and with the traffic environment opens up fantastic possibilities. Vital information can be shared and exchanged – creating a more comfortable and safer drive. The technology is based on communication between transmitters in vehicles and the road infrastructure, such as road signs and traffic lights. The technology makes it possible to transmit information about local icy or slippery road patches from one car to other vehicles.
