High-speed enforcement

German company Traffic Data Systems says its OIML-R134-1 certified low- and high-speed weigh-in-motion system uses three rows of OIML-certified Lineas sensors and is a legally accepted WIM product for enforcement (WIM-E) and tolling applications (WIM-T) to be used on all kinds of roads. For heavy goods vehicles the system can cope with speeds between five to 120km/h while for light goods vehicles the upper limit is 140km/h.

German company 4592 Traffic Data Systems says its OIML-R134-1 certified low- and high-speed weigh-in-motion system uses three rows of OIML-certified Lineas sensors and is a legally accepted WIM product for enforcement (WIM-E) and tolling applications (WIM-T) to be used on all kinds of roads. For heavy goods vehicles the system can cope with speeds between five to 120km/h while for light goods vehicles the upper limit is 140km/h.


Certification has been carried out by the Federal Institute of Metrology METAS (Switzerland) which recorded accuracies of ±5% (initial verification) and ±10% (in-service inspection) in accordance with OIML R134 have been achieved. METAS supervised the certification process requiring more than 500 test runs with different vehicles, speeds and loads. According to Traffic Data Systems, while the results appear to be less accurate than other systems on the market, those results did not follow OIML R134 or cover speeds up to 140 km/h.

    Q-Free’s Marco Sinnema looks at how the commoditisation of high-quality vision-based solutions is widening their application. Machine vision technology’s entry into the ITS/traffic management sector has followed a classic top-down path. This is unsurprising given the extremely demanding performance criteria which are the standard in its market of origin, manufacturing processing. Very high image qualities combined with frame rates often in the hundreds per second range resulted in vision systems with capabi

    For some, machine vision is the coming technology. For others, it’s already here. Although it remains a relative newcomer to the ITS sector, its effects look set to be profound and far-reaching. Encapsulating in just a few short words the distinguishing features of complex technologies and their operating concepts can sometimes be difficult. Often, it is the most subtle of nuances which are both the most important and yet also the most easily lost. Happily, in the case of machine vision this isn’t the case:

The regulations had been introduced under police cooperation rules on the prevention of crime, but the Court decided that the measures in the Directive do not c
