Demonstration of first German A9 motorway safety project

In the first project of the ‘digital A9 motorway test bed’ to show how vehicles on a motorway can share hazard information, Continental, Deutsche Telekom, Fraunhofer ESK and Nokia Networks have carried out a real-time demonstration of communication between vehicles via the Deutsche Telecom LTE cell network.

In the first project of the ‘digital A9 motorway test bed’ to show how vehicles on a motorway can share hazard information, 260 Continental, 4194 Deutsche Telekom, Fraunhofer ESK and Nokia Networks have carried out a real-time demonstration of communication between vehicles via the Deutsche Telecom LTE cell network.

The project, which aims to improve road safety and traffic management, involved upgrading Deutsche Telekom's existing LTE network at sections of the A9 motorway test bed with Nokia Networks’ mobile edge computing technology. The LTE base stations were upgraded with plug-in modules known as cloudlets, which ensure that information is directly routed within the cells, instead of transporting data through the mobile network via the cloud, reducing end to end latency.

The test vehicles contain an on-board unit, connected to the vehicle systems and communicate with the LTE network via a wireless module. Continental supplies the interface to the cars' on-board systems via the CAN bus and the tablet application software. Fraunhofer ESK developed the GeoService software, which ensures that the vehicles' position data is recorded and processed directly at the LTE base station. The geo service at the mobile base stations allows that incident warnings can be sent practically in real-time to all vehicles in the relevant area.

Alexander Dobrindt, the German Federal Minister of Transport and Digital Infrastructure, commented: "With the 'digital A9 motorway test bed', we have created a technology-neutral offering for industry and research. Innovative companies can trial automated and networked driving in real-life conditions on the motorway. We are, in a very real sense, bringing the laboratory to the road. This is the first demonstration of car-to-car communication via a high-speed cellular connection with near-5G performance. With it, we are taking the leap into the digital real-time age on the road. This will make traffic more predictable for drivers and will help prevent traffic jams and accidents. The project highlights the fact that Germany is paving the way for Mobility 4.0 in the digital world. Our ambition is to make the rating 'tested on German Autobahn' internationally recognised as a standard."

    Mercedes-Benz is expanding its research activities in the US, now that it has received a licence permitting it to test autonomous vehicles on public roads in California. The company says it now plans to take autonomous driving to a new level in the US, despite the differences between US and German traffic systems, which it says are vast. While motoring in Germany commonly takes place on narrow roads, the roads in the USA are frequently wider and may have more than six or even eight lanes. Traffic lights

    Wireless transmission of data and control information is making smarter traffic management easier and cheaper to install. It has long been known that connectivity is the key to improving traffic management and many cost-benefit studies prove that investment in new technology can be justified in terms of reduced congestion, shorter travel times, improved safety and air quality. However, many authorities’ cap-ex budgets only cover urgent matters, not improvements, making it difficult, if not impossible to
