A Radar System to Be Installed On the Streets for Safety of Pedestrians

Apr, 2021 - By WMR

Three independent divisions of Germany's Fraunhofer research group are currently working on the framework as part of the HORIS initiative. With the help of artificial intelligence, the Fraunhofer researchers' machine will be able to perceive and comprehend whole scenarios on the track.

Whenever a pedestrian runs into the road or the vehicle, a radar sensor device may give an early warning to drivers and self-driving cars. It contains infrastructure-connected MIMO radar sensors that could be mounted in high-traffic areas like school zones, crosswalks and bus stops. Pedestrian-detecting radar systems are now standard in many cars, and they can also be obstructed by barriers like buildings or other vehicles. Although, by bringing the radar to the streets, a modern design is planned to resolve this challenge.

Each sensor device may recognize an individual as a human by inspecting the area over 100 times per second, and then determine the pace and direction at which they're walking or running, whether they're moving at all. The vehicle-to-infrastructure (V2I) device in nearby cars will pick up such a wireless signal, allowing an audio/visual warning to evoke in any vehicles which was about to reach the pedestrian. The technology may also be able to unlock the brakes on certain vehicles automatically.

Furthermore, even though no one was about to move into the lane, the device might warn drivers to slow down if they entered a place where a significant number of pedestrians were milling about on the sidewalk. There shouldn't be any privacy issues since there are no cameras involved. The system is being displayed at a bus stop on the Technische Hochschule Ingolstadt University's campus, despite the fact that it is still in progress. A system with two radar sensors can track up to eight people at once and determine whether all of them are heading toward the lane.
