Smart Intersections Act of 2021

The Smart Intersections Act of 2021 would establish a federal grant program to help state, local, and tribal governments upgrade traffic signals with "smart" technology. These improvements aim to reduce traffic congestion and idling time by using active management systems that adjust signal timing based on real-time traffic flow. For citizens, this could lead to shorter commutes, improved road safety, and lower fuel costs, while a required federal study would evaluate how these efficiencies might also reduce greenhouse gas emissions.
