smart traffic light
/smɑːrt ˈtræfɪk laɪt
EN
An adaptive traffic signaling device that uses sensors, artificial intelligence, and real-time traffic data to adjust signal timing, reduce congestion, and improve road safety.
Many major cities are installing smart traffic lights to cut down on rush-hour wait times at busy intersections.
Etymology
The term combines 'smart' (referring to connected, intelligent technology, first adopted for digital devices in the late 20th century) with 'traffic light', which was coined for road signal devices in the late 19th century. The combined term emerged in the early 2000s as smart city infrastructure development grew.
