Kistler installs WiM system on Czech highway

The Czech Metrology Institute (CMI) has approved a Weigh in Motion (WiM) system from 657 Kistler to help prevent road damage from trucks.

Kistler, a measurement technology company, says its KiTraffic system is being used to track and fine overloaded trucks on the D7 Highway from Prague to the north-west of the country.

KiTraffic is comprised of Lineas brand quartz sensors integrated into the road, cameras, hardware and software. If a truck exceeds the weight limit, the system sends the weight and a photograph of the vehicle to the authorities who can then send a standard letter to fine the owner, the company adds.

It was installed in collaboration with system integrator Spel on a new section of the highway. As part of an accuracy test, the team weighed vehicles from categories B (a 994 Volkswagen transporter), C (a six-axle truck) and D (a bus) on stationary scales and then in motion via the WiM system. Kistler passed CMI’s maximum error margin of 5% per vehicle and 11% per axle.

Tomas Pospisek, global market development manager for road & traffic EMEA at Kistler, says: “This error margin is factored in by the system to make sure no vehicle is fined incorrectly.”

The WiM system was certified by the International Organisation of Legal Metrology (OIML) and the Swiss Federal Institute for Metrology.

“There is currently no pan-European certificate for WiM systems. However, having already obtained a more general measuring certificate, the OIML helped us to get approved in the Czech Republic,” Pospisek continues. “This meant we were able to skip some tests and save time.”

Looking ahead, Kistler is hoping to open 15 WiM stations on Czech highways.

    Swiss company Haenni Instruments is highlighting the WL 108 XL portable wheel load scale. Its active surface of 1395 x 393 mm is big enough to accommodate the wheels of vehicles of any size, with any axle configuration. Despite its huge weighing area, the device weighs only 28.5 kg and is equipped with rechargeable batteries that power it for at least 120 hours before it needs to be recharged.

    Having won the 2016 Intertraffic Innovation Award, Cross Zlin is back again with a host of new products including a shortlisted fibre-optic based weigh-in-motion system called OptiWim. Marketing manager Libor Sušil describes the system as weigh-in-free-flow as it measures the axle across the full lane width regardless of the position of the wheels and the sensor can also detect underinflated tyres even on twin wheel configurations. He likens the measuring method to that of a strain gauge but adds that
