Cease-and-go visitors in cities is annoying. Against this, we’re happy when we now have a “inexperienced wave”—however we catch them far too seldom, sadly. With the Site visitors Mild Info operate, drivers are extra in management. They drive extra effectively and are extra relaxed as a result of they know 250 meters forward of a visitors gentle whether or not they’ll catch it on inexperienced. Sooner or later, anonymized knowledge from our automobiles may help to change visitors lights in cities to raised phases and to optimize the visitors movement.—Andre Hainzlmaier, head of Improvement of Apps, Related Providers and Sensible Metropolis at Audi

Explaining the lagged introduction of the service in Europe, Hainzlmaier stated that the challenges for the serial introduction of the service there are a lot higher than within the USA, the place city visitors gentle methods have been deliberate over a big space and uniformly.
In Europe, against this, the visitors infrastructure has developed extra domestically and decentrally—with an amazing number of visitors expertise. How shortly different cities are related to this expertise relies upon above all on whether or not knowledge requirements and interfaces get established and cities digitalize their visitors lights.—Andre Hainzlmaier
