smart road

a.k.a. smart road technology, adaptive signals

The latest use of smart technology involves traffic cameras and monitoring software which then adjust real-time "adaptive signals" to better guide traffic flow.

Historical perspective: In 2014 the city of Sioux Falls, South Dakota equipped ten intersections with cameras and adaptive signals, which use real-time traffic flows to adjust traffic signals, so drivers shouldn’t have to wait so long for lights to change.
