While 30 years ago there were still energy-guzzling lightbulbs at the intersections, a power-saving miracle was installed on Landwiedstrasse. A mini battery would suffice for operation.
The first traffic light was set up in Linz exactly 88 years ago. Traffic is currently regulated by 204 systems with around 10,000 light points. “We are one of the few cities in Austria to have replaced all light bulbs with LED lamps,” says VP City Vice President Martin Hajart, who sees the provincial capital in a pioneering role. Traffic light set up in LandwiedstraßeThe first one-watt traffic light that recently went into operation in Landwiedstraße also contributes to this. This advanced new development, also known as VLP (Very Low Power) technology, could theoretically be operated by a tiny battery for several hours. From 100 to one watt In any case, the traffic light requires significantly less power than its predecessors. They had standard 100-watt lightbulbs installed in the late 1980s. It was not until the 1990s that “low-voltage lamps” (40 watts) came into use. Finally, LED technology brought about a real quantum leap.Artificial intelligence regulates road crossingsTraffic lights with artificial intelligence are also in the fast lane. As reported, one of the first systems in Austria went into operation at the Michel-Reitter School, which recognizes passers-by and gives them the green light without touching the traffic light. Pilot project for autonomous driving planned The technology for communication between cars and traffic lights is not yet fully developed. “In this area, too, pilot projects are being worked on, which will be used to test various services,” says Hajart.
