Traffic Data Systems (TDS) highlights that it is the only manufacturer in the world capable of supplying low- and high-speed weigh-in-motion (WIM) systems that are in compliance with the OIML R134 standard for enforcement and tolling applications.
Moreover, extensive laboratory measurements have also been carried out successfully in the temperature range -30°C/+75°C with a relative humidity of up to 85%, and a certificate for the equipment has been issued by the Swiss Federal Institute of Metrology, METAS.
With the WIM-DSP 32/TMCS-U, Traffic Data Systems is capable of providing an OIML-R134-certified low-speed and high-speed WIM system with only three rows of OIML-certified Lineas sensors for a speed range of 5 km/h to 120 km/h for HGVs (Heavy Goods Vehicles) and for 5 km/h to 140 km/h for LGVs (Light Goods Vehicles).
Accuracies of ±5% (initial verification) and ±10% (in-service inspection) respectively in accordance with OIML R134 have been achieved. For customers, the OIML certificate is an officially proven sign of quality at the highest level: only documents of this kind are accepted by local government authorities for calibrating WIM systems before they can be used for enforcement or tolling.
Besides enforcement and tolling application, TDS says this system can also supply very precise weight information for road and bridge maintenance, which hasn't been known in the past. This year, Traffic Data Systems and the city of Hamburg agreed to cooperate in the field of weigh-In-motion in order to present a PTB (National Metrology Institute of Germany) accepted system at the ITS World Congress in 2021 which is being hosted by the City of Hamburg.
