The power of collaboration: How we can reduce traffic congestion
Google Research engineers discuss a study on using navigation app interventions to optimize traffic flow system-wide. By coordinating a fraction of vehicle routes, the researchers aim to reduce congestion and CO2 emissions.
Why it matters
Effective traffic management has significant implications for urban sustainability, economic productivity, and reducing global carbon emissions.

We demonstrate the effect of network-aware routing in navigation apps on improving network efficiency.
Vehicle transportation underpins much of modern life, enabling the movement of goods and people, productivity, and economic growth. However, the costs are high: drivers spend an average of 2.6 years of their life on the road , and private cars and vans now account for around 10% of global CO2 emissions . Hence, the efficient use of transportation networks is of paramount importance. Can road traffic routing be managed system-wide the way aviation manages airspace or the internet routes data packets? While ground transportation has historically lacked a physical control tower, digital platforms offer a powerful glimpse into a more coordinated future.
