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.

    It would be easy to fall into the trap of seeing machine vision as the vision-based solution for ITS and traffic, however Patrik Anderson, Director Business Development Transportation of Axis Communications, notes that many of the applications which are coming to be associated with machine vision – and, indeed, many of the characteristics, such as at-the-edge analytics and image processing – are also possible with open-standard networked video. Networked video brings a whole host of advantages, such as the

    An independent off-street parking benchmark study carried out by automotive technology research firm SBD has concluded that ParkMe, an Inrix company, beat Parkopedia in data accuracy across the key attribute categories in five cities in the US and Germany. According to the study, overall, ParkMe was 12 per cent more accurate than Parkopedia across a set of core attributes that are essential to automakers for customer satisfaction. Most important, ParkMe was 23 per cent more accurate providing the precise
