Volvo's Smart Cars Share Icy Road Alerts

Volvo looks to test a fleet of 1,000 cars that can share information about road conditions

Most drivers have to fight icy patches during bad winter weather by themselves. Swedish carmaker Volvo envisions a different world where cars share information with one another about slippery road conditions—and it’s building a roving swarm of 1000 smart cars to test the idea.

Volvo’s test fleet of cars would rely upon a cloud-based network to share information about driving conditions. If one car encounters an icy patch, it could transmit a slippery-road warning broadcast to other cars in the fleet. Another car that might have to stop and put on its hazard lights would also automatically broadcast its location to nearby vehicles. Those two features serve as first steps toward a grander vision for Volvo.

“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,” said Erik Israelsson, project leader of the Cooperative Intelligent Transport System at Volvo Cars, in a press release.

The cloud-based warning system could also alert public officials about where they need to tackle winter road maintenanceVolvo Cars is working on the new project with the Swedish Transport Administration and the Norwegian Public Roads Administration.

Part of the project involves Volvo boosting its current test fleet of 50 cars to 1000 cars. The carmaker plans to deploy the test fleet to Gothenburg in Sweden and Oslo in Norway to see how the system fares in deep winter conditions.

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.

Volvo also plans to test other concepts for communicating road safety alerts through cloud-based networks. A separate warning system aims to alert both car drivers and bicycle riders in case of impending collision so that both can take action.

That’s all well and good as long as human drivers remain behind the wheel. But Volvo, like Google, also wants to test autonomous vehicle technologies that could potentially react much faster to dangerous situations than any human. For instance, Volvo’s engineers are developing trucks that can automatically take over the steering or brakes to avoid accidents. A separate fleet of Volvo cars is also testing self-driving robot car technology on the streets of Gothenburg.

Self-Driving Cars Work Better With Smart Roads

Intelligent infrastructure makes autonomous driving safer and less expensive

A photograph shows a single car headed toward the viewer on the rightmost lane of a three-lane road that is bounded by grassy parkways, one side of which is planted with trees. In the foreground a black vertical pole is topped by a crossbeam bearing various instruments. 

This test unit, in a suburb of Shanghai, detects and tracks traffic merging from a side road onto a major road, using a camera, a lidar, a radar, a communication unit, and a computer.

Enormous efforts have been made in the past two decades to create a car that can use sensors and artificial intelligence to model its environment and plot a safe driving path. Yet even today the technology works well only in areas like campuses, which have limited roads to map and minimal traffic to master. It still can’t manage busy, unfamiliar, or unpredictable roads. For now, at least, there is only so much sensory power and intelligence that can go into a car.

To solve this problem, we must turn it around: We must put more of the smarts into the infrastructure—we must make the road smart.
