Florian Weiss, president and CEO of Traffic Data Systems (TDS) says it is still the only manufacturer in the world capable of supplying low- and high-speed weigh in motion (WIM) systems complying with the OIML R134 standard for enforcement and tolling applications.

The latest design of its WIM-DSP 32/ TMCS-IP WIM enforcement/tolling system is now available. The TMCS also comes in a solid, all-aluminium enclosure to protect against dust and water, called TMCS-IP, similar to TDS’s proven WIM-DSP 32.

TDS is also promoting its collaboration with the city of Hamburg – host of the ITS World Congress in 2021 – to set up Germany´s first fully automated WIM enforcement system to be certified by the Federal Institute of Metrology (METAS), Switzerland. TDS also hopes that the system will be given the green light by PTB, the German metrological institute.

This highway installation will not only be equipped with WIM sensors, but also with ANPR and overview cameras, laser scanners and profilers, as well as a fully-equipped road weather information system (RWIS). Meanwhile, TDS points out that it is currently capable of providing OIML R134-certified low-speed and high-speed WIM systems 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% (inservice inspection) according to OIML R134 have been achieved (temperature range -30°C/+75°C with a relative humidity of up to 85%).

TDS’s latest research and development aims to improve accuracies to ±2.5% (initial verification) and ±5% (inservice inspection).
