(Photo: Fraunhofer)<\/small><\/center>Researchers in Germany have found that equipping traffic lights with AI technology could help reduce the amount of time drivers spend at intersections.\u00a0<\/span><\/p>\n

Traffic lights usually coordinate with induction loop sensors or infrared sensors, which are either built into the roads or affixed atop traffic lights to detect the presence of vehicles. When the sensors notice that vehicles have queued, they trigger a change in the signal itself that allows those vehicles to pass. Signals may also be influenced by predetermined schedules, which (if your municipality knows what it\u2019s doing) are based on the flow and needs of traffic around specific times, like rush hour.\u00a0\u00a0<\/span><\/p>\n

These methods aren\u2019t perfect, though\u2014anyone who\u2019s torn their hair out at a long light can tell you that. That\u2019s why Germany\u2019s KI4LSA project, funded by the German Federal Ministry of Transport and Digital Infrastructure, seeks relief in the form of AI technology that can be paired with existing traffic light systems.\u00a0<\/span><\/p>\n

The Fraunhofer Institute for Optronics, System Technologies and Image Exploitation, one of KI4LSA\u2019s many partner organizations, helped kick off the project by <\/span>installing<\/span><\/a> radar sensors and high-resolution cameras at a busy intersection in the city of Lemgo. These devices recorded how many vehicles were required to wait for lights to change, how long they waited, and the average speed at which each vehicle passed through the intersection when its turn arrived. This information was fed into a machine-learning-based computer algorithm, which then generated various traffic light patterns to determine which ones would effectively reduce wait times.\u00a0<\/span><\/p>\n

At their most impactful, these AI-powered patterns were capable of improving traffic congestion by 10 to 15 percent\u2014though researchers are still testing whether the algorithm\u2019s predictions would correspond in totality with real-life conditions. Those involved with the project will test out running the algorithm at the Lemgo intersection over the next few months, allowing Fraunhofer to make alterations to the system as needed. Fraunhofer will simultaneously be involved in a similar project called KI4PED, which focuses on pedestrian\u2019s traffic needs and uses the organization\u2019s AI capabilities along with LIDAR sensor data.<\/span><\/p>\n

Some civilians are skeptical that AI would ever become a facet of American streets, but the odds might be higher than they think. State and municipal governments routinely contract private tech companies to install and manage their public equipment; Redflex and L3 Technologies (now L3Harris) manufacture and operate a wide swath of US red light cameras and traffic sensors, for instance, so it wouldn\u2019t be unreasonable for a company with AI capabilities to swoop in, especially as the technology becomes more normalized.<\/span><\/p>\n
