HERE, Porsche, Vodafone develop 5G real-time traffic warning system
HERE Technologies, Porsche and Vodafone Germany are testing how 5G technology and high-precision localisation can make traffic safer and reduce the number of traffic accidents. Together, the companies are working on a real-time warning system. Specifically, vehicles and their occupants are to receive hazard reports immediately and without delay so that they can react to them directly. In the Vodafone 5G Mobility Lab near Aachen, the partners are now testing the real-time warning system under conditions similar to everyday life.
The development focuses on dangerous situations that are not visible or difficult to see for the occupants, for example because the view is blocked by vehicles in front. Captured by camera and sensor systems using artificial intelligence and precisely localised with high-precision mapping and positioning technology, the data obtained will in future be processed and evaluated directly at the edge of the road, in Multiaccess Edge Computing (MEC). Subsequently, they will be transmitted to the following road users without delay in the form of dedicated warnings via 5G mobile communications technology and an intelligent MQTT message broker.
In addition to HD maps and positioning technology, the Live Sense SDK from HERE Technologies is also used to detect dangerous situations. Integrated into devices with front cameras, it uses computer vision and artificial intelligence to identify objects, changes in the behaviour of other road users and road conditions that could lead to critical situations. Based on this, Live Sense SDK creates appropriate warnings for drivers in real time.
In many cases, data processing takes place in central data centres. With Multiaccess Edge Computing (MEC), the computing power moves closer to the customer – in this case to the vehicles – instead of to a central cloud infrastructure. This saves time and enables data exchange in real time. The paths that the data must take to reach the recipient are significantly shortened. Thanks to 5G, no time is lost in the actual data transmission either, so that danger warnings arrive in the vehicles with latency times of less than ten milliseconds, i.e. practically in real time. In addition, with these low turn-around times, data can also be processed outside in the future that was previously processed directly in the vehicle.
Following the first tests in Aldenhoven, the development partners want to further optimise the real-time warning system and test its use in everyday life. Further tests at different locations and under variable conditions are to follow.
