Digital Guardian Angel makes Urban Road Traffic in Hamburg Safer

Collaboration between Continental, Deutsche Telekom, Vitronic and the City of Hamburg to develop the system.

Visitors to the ITS World Congress 2021 will experience first- hand – how a collision warning system from Continental will act as a digital guardian angel, providing efficient protection for vulnerable road users in the future. The system, which is being further developed in collaboration with technology company Continental, Deutsche Telekom, Vitronic Dr. Ing. Stein Bildverarbeitungs GmbH and the City of Hamburg, warns of collisions in real time using a smartphone. For this, the Continental solution calculates the route over the next five seconds using GPS and speed data from cars and smartphones in a Telekom cloud computer in the immediate vicinity.

The application does not require dedicated hardware; therefore it can easily be integrated into apps from Deutsche Telekom or urban mobile applications, such as municipal transport providers. The collision warning is integrated into the vehicle functions, so that drivers are warned immediately of imminent accidents.

“A system like this needs a high degree of interconnectivity and information processing speed to function,” says Oliver Bahns, who is responsible for connected mobility at T-Systems. Cars and cyclists transmit their position and acceleration to Telekom’s cloud computers. These then calculate the paths for the next five seconds and send a warning of any impending collision to the car and the cyclist’s terminal device in the event. To ensure that this information reaches both road users as quickly as possible, the cloud computer is always active in the mobile network closest to the possible collision. Multi-Access Edge computing processes the GPS signal in combination with other position and navigation data to locate the road users’ smartphones with an accuracy of less than one meter. Everyone who might be involved in an accident is notified in less than a second. This is done either by a warning on the assistance system in the car or by a visual and acoustic message with a vibration alarm on the smartphone, which is also forwarded to smartwatches. This enables users to respond quickly to prevent an accident.
