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 EU-co-funded I_ HeERO (Infrastructure_ Harmonised eCall European Pilot) project is working to ensure the readiness of national networks of call centres - known as public safety answering posts (PSAPs) - to deal with automated crash alerts arriving via the continent-wide 112 emergency phone number. Following on from its HeERO and HeERO2 pre-deployment predecessors, which enjoyed €16m (US$17.76m) in EU funding, the new initiative runs from 1 January 2015 to 31 December 2017. It has €30.9 million (US$34.

    In the wake of the VW scandal John Kendall looks at emissions testing on both sides of the Atlantic. Since the VW emissions story broke in September, emissions testing has come under greater scrutiny, and none more so than in Europe, where critics have long been highlighting the weaknesses of the testing system. Ironically, changes to the emissions testing process were already under review but the story has pushed it up the agenda.

    Deryk Whyte provides an overview of how the New Zealand Transport Agency's InfoConnect concept was developed. Historically, the New Zealand Transport Agency (NZTA) (formerly Transit New Zealand) has faced challenges in communicating effectively with road users, its customers, about highway-related events or incidents in a timely, accurate manner. Prior to 2007, Transit relied on a third-party organisation to collect and disseminate national road condition information. This often resulted in incomplete infor
