ITS World Congress 2021 - Real-time collision warning!

Visitors to the ITS World Congress 2021 will experience first hand how a collision warning system from Continental, as a digital guardian angel, will ensure efficient protection of endangered road users in the future. The system, which was developed in cooperation with the technology company Continental, Deutsche Telekom, Vitronic Dr. Ing.Stein Bildververarbeitung GmbH and the City of Hamburg, warns of collisions in real time via smartphone. To do this, the Continental solution calculates the traffic route for the next five seconds from GPS and speed data from cars and smartphones in a Telekom cloud computer in the immediate vicinity.

ITS World Congress 2021

• Real-time collision warning protects particularly vulnerable road users such as pedestrians, cyclists and scooter drivers
• Cloud application does not require any separate hardware and can be integrated into smartphone apps
• Cooperation between Continental, Deutsche Telekom, Vitronic and the City of Hamburg

For this purpose, the system uses data from detected traffic objects from Vitronic as well as traffic light data and an exact digital map provided by the City of Hamburg in intersection areas. The warning of an impending collision is sent in real time via Deutsche Telekom's Low Latency Network to road users who have a corresponding T-Systems app on their smartphone. In this way, the digital guardian angel technology protects particularly endangered, non-motorized road users such as pedestrians, bicycles, scooters, but of course also motorists from accidents. The solution is currently being tested live as part of the pilot project Reallabor Hamburg and is being installed on the test track for automated and networked driving (TAVF).

“For Continental, our“ Vision Zero ”- that is, zero traffic accidents - has top priority when developing new products. With the digital guardian angel developed in partnership, we are well on the way to coming much closer to it in combination with our other assistance systems, ”says Dr. Karsten Michels, Head of Central Advanced Development at Continental. “The challenge so far has been that the sensor system does not record all people around the vehicle, depending on the visibility conditions. Therefore, connectivity via the cloud is a much more effective way of reaching and protecting a large number of road users. "

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

"The prerequisites for such a system to work are the high degree of networking and the speed of information processing," says Oliver Bahns, responsible for Connected Mobility at T-Systems. Cars and cyclists transmit their position and acceleration data to Telekom's cloud computers. They calculate the routes for the next five seconds and send a warning to the car and the cyclist's device if a collision is imminent. In order for this information to reach both road users as quickly as possible, the cloud computer in the cellular network that is closest to the location of the possible collision is always used. The so-called Multi-Access Edge Computing processes the GPS signal in combination with other position determination and navigation data in order to locate the smartphone of the road user with an accuracy of less than one meter. In less than a second, everyone involved in a possible accident is notified. This happens either through a warning from the assistance system in the car or a visual and acoustic message with a vibration alarm on the smartphone, which is also forwarded to smartwatches. In this way, users can react at lightning speed and prevent an accident.

Smart intersection that protects against accidents

Together with the Free and Hanseatic City of Hamburg, Continental, Deutsche Telekom and Vitronic have implemented the application in a street crossing in Hamburg. The IDTE solution (Intelligent Detection and Tracking Equipment) installed and operated by Vitronic on the infrastructure side overlooks the entire intersection and provides Continental with the data corresponding to the traffic objects being monitored. The interaction with road users is handled by the collision warning system from Continental. In the intersection area, the system also accesses traffic light switching data from the city of Hamburg, so that it can warn users who, for example, are approaching the intersection despite the red traffic light. The solution even records near-accidents, which traffic planners can use to make inner-city traffic safer and to mitigate accident black spots. In this way, the partners make a significant contribution to making cities safer and greener.

All cooperation partners - Continental, Deutsche Telekom and Vitronic - present the solution at the ITS World Congress. The technology funded by the Federal Ministry of Transport and Digital Infrastructure should be available for mass rollout in 2024. In the Hamburg district of Bergedorf, Continental is also using self-driving shuttles together with partners in a further project as part of the real-world laboratory as a supplement to local public transport.

Continental at the ITS World Congress 2021

From solutions for the smart city and fleet management to networked systems for more safety in road traffic to robotics technologies and autonomous shuttles: At the ITS World Congress in Hamburg (October 11-15, 2021), Continental (Hall B5, Stand 410) fully on the intelligent and autonomous mobility of the future. As part of the Hamburg Real Laboratory and the national future of mobility platform, Continental is also testing various developments in Hamburg's urban traffic.

Of course, that wasn't the end of it!
