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.

    The E-ZPass Group is to work with OmniAir Certification Services (OCS) to specify a testing program for ensuring full compliance of competitive equipment with E-ZPass readers and tags. OCS was hired by the E-ZPass Group for fees of around US$50,000 to detail the testing needed. The documents are due to be completed by the end of the year. Actual testing for certification will be negotiated by manufacturers with OCS-accredited testing firms. The move to certify additional suppliers’ equipment follows K

Lincolnshire is the UK’s fourth-largest county, has a population of over a million and is predominantly rural. Only 66km of its 8,893km road network is dual carriageway and 79% of the rest is ‘C’ class or unclassified roads. In terms of Killed and Seriously Injured (KSI) figures, there were 415 casualties in 2013 (down from 526 in 2002). Official figures show inappropriate speed accounts for 25% of the UK’s

    Overlaying a geographic information system with data from a new surveying system is paying dividends for Utah DOT. While building new roads tramways, metros and bicycle paths or installing smart systems to control traffic is the high-profile end of transportation planning and management, ensuring existing infrastructure and systems are serviceable and working is arguably more important. After all, at any given point the existing infrastructure will always carry more vehicles than new.
