G08G

TRAFFIC CONTROL SYSTEMS (guiding railway traffic, ensuring the safety of railway traffic B61L; arrangement of road signs or traffic signals E01F9/00; radar or analogous systems, sonar systems, lidar systems specially adapted for traffic control G01S13/91, G01S15/88, G01S17/88; )

Introduced: September 1968

Description

G08G covers signalling systems and devices designed to regulate, direct, and manage traffic flow on roads, railways, waterways, and airways. It encompasses traffic lights, warning signals, collision avoidance systems, congestion management technologies, and automatic vehicle control devices. The subclass includes both infrastructure-based systems (fixed signals and sensors) and vehicle-integrated systems that communicate traffic information to drivers or autonomous vehicles. Related technologies for general alarm or warning systems are classified elsewhere under G08B.
