The granting of type approvals for measuring instruments which are used in road traffic (speedometers) falls within the province of PTB. The Working Group "IT Measuring Instruments for Traffic Enforcement" of Department 1.3 "Velocity", supports manufacturers in the development of the device software of speedometers. Type testing is increasingly focussed on digital single-spot cameras or video cameras which are used to document the traffic situation and, to an ever increasing extent, also on the software-supported analysis of complex traffic situations. Here, the main focus is on the software which must guarantee real-time-capable triggering of the camera, the interpretation of the image information and tamper-proof storage of the image files. The partial approval tests which are required in this connection are carried out by the Working Group "IT Measuring Instruments for Traffic Enforcement".
