Time over distance

Australia's approach to speed enforcement and accident reduction has moved from point speed capture to corridor speed enforcement, often called Point to Point (PTP) or Time over Distance (ToD). The first multi point location PTP system with simultaneous point speed enforcement is operational in the Roads and Traffic Authority of New South Wales. PTP works on the principle of average vehicle speed over a given distance. PTP systems cannot detect a speeding offence until the vehicle has passed the checkpoints. Therefore data for every vehicle that passes needs to be processed. Licence plate/tag optical character recognition is used so that information regarding vehicles not speeding can be discarded. The Redflex PTP system used by the Road Traffic Authority is both a conventional speed camera system as well as a PT system, providing 100% vehicle detection and identification.
