RetroTek-MU certified as dynamic mobile retroreflectometer

The RetroTek-MU (RTM) has been certified to ASTM E 1710 standard as a dynamic mobile retroreflectometer, according to testing, monitoring and certification association for road-owners, StrAus-Zert (SAZ). It is capable of measuring road markings / striping across the full width of a traffic lane simultaneously in one pass at traffic speeds up to 75mph and can be operated by one driver. The assessment, carried out by SAZ's Dr Hans-Hubert Meseberg, also confirmed that the RTM

The RetroTek-MU (RTM) has been certified to ASTM E 1710 standard as a dynamic mobile retroreflectometer, according to testing, monitoring and certification association for road-owners, StrAus-Zert (SAZ). It is capable of measuring road markings / striping across the full width of a traffic lane simultaneously in one pass at traffic speeds up to 75mph and can be operated by one driver.

The assessment, carried out by SAZ's Dr Hans-Hubert Meseberg, also confirmed that the RTM is capable of measuring the night visibility of road / lines striping on the right and left including the lane markings in its centre.

Dr Meseberg added that its measuring system provides the same measured values of the coefficient of retroflected luminance RL as a portable, handheld measuring device, within the scope of an acceptable measuring accuracy. In addition, the coefficient of retroreflected luminance RL can be detected with a good measuring accuracy by the measuring system RTM, independent of the measuring velocity.

In his overall assessment, Dr Meseberg stated that the deviations of the measurement results are low, considering that the measuring conditions cause inaccuracies that are not a result of the device itself. These conditions include measuring areas, uneven marking surface, non-homogenous structure of the marking surface and non-homogenous bead distribution.

    Truvelo UK’s D-CAM digital speed and red light enforcement camera has now gained UK Home Office Type Approval. The camera has been approved for both front and rear photography which, together with choices for the positioning of road markings for secondary speed checks, dramatically increases siting flexibility, as well for as speed on green enforcement. A patented solution which forms a part of the Home Office type approval is the ability to monitor signal phases on newer-generation LED traffic lights.

    David Crawford looks at the latest thinking about calculating the benefits associated with the environmental side of ITS schemes. The penny is dropping that some environmental costs “are being shifted outside the traditional bounds of evaluation methods” for ITS-based road transport projects, according to researchers at the UK University of Leeds’ Institute for Transport Studies.

    A major weigh-in-motion (WIM) innovation being featured here at the ITS World Congress by Kistler has already won accreditation from the International Organisation of Metrology (OIML). To address the ever increasing problem of road surface damage caused by heavy transport, WIM systems employing Kistler quartz sensors have been delivering valuable traffic data for many years. There is also a long tradition in using WIM for preselection of overloaded vehicles.
