Traffic. We all hate it, but what can honestly be done to significantly reduce it? Well, according to an experiment conducted by the university of Illinois, simply introducing a few self-driving cars to roads could be the answer. Conducting experiments in Tucson, Arizona the team discovered that even adding a single autonomous vehicle to the roads can massively reduce traffic. They programmed a self-driving car to loop a track continuously and then added 20 other human-driven cars to the mix.
While humans somehow naturally create stop-and-go traffic even without lane changes or other disruptions, thanks to the robotic racer, both traffic and fuel consumption were reduced by 40 percent.
