SECTION G – PHYSICS


G 08SIGNALLING (indicating or display devices per se G09F; transmission of pictures H04N)


G 08 GTRAFFIC CONTROL SYSTEMS (guiding railway traffic, ensuring the safety of railway traffic B61L; arrangement of road signs or traffic signals E01F 9/00; radar systems or analogous systems, designed for traffic control G01S 13/91; sonar or lidar systems specially designed for traffic control G01S 15/88, G01S 17/88) [2]


Note

 This subclass covers:

 identification of traffic offenders;

 indicating the position of vehicles for traffic control purposes; [7]

 navigation systems for traffic control purposes, i.e. systems in which the navigation is not performed autonomously by or in the vehicles, but where the vehicles are guided by instructions transmitted to them; [7]

 indication of free spaces in parking areas.
