Traffic light countdown timer
/ˈtræfɪk laɪt ˈkaʊntaʊn ˈtaɪmər/
EN
A digital or mechanical device paired with a traffic light that displays the remaining seconds until the signal changes, helping drivers and pedestrians plan their movement.
Many urban intersections now install a traffic light countdown timer to reduce red-light running violations.
Etymology
The term combines 'traffic light' (coined in the late 19th century for road intersection signals) with 'countdown timer', a term that became common in the 20th century as electronics were integrated into road infrastructure.
