Google Research has conducted a large-scale study in 10 major US cities to explore how navigation apps can reduce traffic congestion and emissions. By modifying the Google Maps algorithm to subtly reroute a small percentage of trips away from congested areas, the experiment demonstrated measurable improvements in city-wide driving speeds and reduced CO2 emissions. This research, published in Nature Cities, establishes a framework for moving towards a cooperative routing paradigm that enhances overall network efficiency. AI
