TDS: Device certification is vital

Besides loop-based traffic counters/classifiers, Traffic Data Systems (TDS) is focusing on its OIML-certified Weigh in Motion (WIM) system for enforcement and tolling applications.

But more than that, the company is addressing the issue of device certification. In cases where customers opt for the wrong or improper OIML R134 certification, WIM systems will not be legal for enforcement and tolling, which also results in reputation damage for the correctly-certified systems.
As Florian Weiss, CEO of TDS points out, although there are several manufacturers of WIM systems, only very few fulfil the requirements of OIML R134. The problem, even within the EU, is that certifications of certain metrological institutes are not recognised by other metrological institutes.

Weiss states that there is no confusion with certification for TDS’s WIM systems. For instance, the TDS TMCS-IP /WIM-DSP 32 has been certified by Metas in accordance with the requirements of OIML R134-1.

The system fulfils the requirements of OIML R134 Class F/10. This corresponds to a maximum measuring error of ±5% (initial verification) or ±10% (in-service inspection).  

“TDS was the first manufacturer in the world to have a certified and verifiable low and high-speed WIM system with only three rows of sensors,” Weiss proudly states.  

“This not only covers the requirements of OIML R134-1 (Class F/10), but also the speed range from 5 km/h to 120 km/h for heavy goods vehicles required by the German TLS 2012 standard, Technical Conditions of Supply for Roadside Remote Stations (temperature range: -30°C/+75°C at up to 85% relative humidity). For light goods vehicles, the certified speed range is 5 km/h to 140 km/h.”
