Kistler launches WiM system for overloads

Kistler has developed a Weigh in Motion (WiM) system which it says offers a 2% accuracy rate in gross vehicle weight independent of driving manoeuvres or road conditions.

The company explains KiTraffic Digital incorporates multiple quartz crystals that independently deliver data via a digital interface. The digital measuring signal permits individual calibration of each quartz crystal and is expected to prevent signal interference on the transmission path. Algorithms work with measurement signals to calculate the wheel, axle and total weight of each vehicle.

According to Kistler, the sensor delivers reliable results when the vehicle being measured is about to overtake and is driving diagonally over the WiM sensor arrangement, while users can also monitor any number of lanes. KiTraffic Digital records information on tyre condition without the need for additional hardware and even removes the need for induction loops for vehicle detection, the company adds. The system can be integrated into third-party traffic monitoring systems.

    Wider uses for weigh in motion data
    Colin Sowman talks to Terry Bergan of International Road Dynamics about the latest uses of weigh-in-motion systems. Raising allowable truck weight limits improve transport efficiency but leaves an ever-increasing number of bridges vulnerable to being overloaded and damaged by vehicles heavier, and in some cases far heavier, than they were designed to carry. The simplistic solution is to impose weight restrictions and erect appropriate signs - but this could have severe knock-on effect on trucking operations

    WIM system certification is a complex business
    There are interesting moves afoot to create Germany’s first Weigh-In-Motion enforcement site in Hamburg – but Florian Weiss of Traffic Data Systems warns that WIM certification is a complex business. In the past, Weigh-In-Motion (WIM) was mainly used for statistical (WIM-S) and pre-selection (WIM-P) applications. These abbreviations - as well as WIM-E (enforcement) and WIM-T (tolling) - were created by Traffic Data Systems during Intertraffic 2006 in Amsterdam. This was also the year when we started the

    On a WIM – a global view of weigh in motion
    Q-Free’s Andrew Lees looks at regional characteristics and technology trends in the global Weigh-In-Motion market. The principles of Weigh-In-Motion (WIM) are well established. Data derived from vehicles passing over in-ground sensors can be interpreted for vehicle classification (axle counts and spacing) and positive identification (especially when linked to image capture) applications as well as to derive individual axle and gross vehicle weight (GVW).
