KiTraffic Digital

Weigh In Motion solution

KiTraffic Digital is far more than just another Weigh In Motion (WIM) system: Kistler is now proud to present the world’s most advanced digital WIM platform. With outstanding accuracy levels and a range of smart features, KiTraffic Digital harnesses the power of digitalization to revolutionize the future of road safety.

Traffic loads – and overloaded vehicles in particular – significantly impact the condition of roads and bridges. The solution? KiTraffic Digital from Kistler, powered by cutting-edge sensors and precision engineering to deliver accurate real-time weight measurements of vehicles moving at any speed. This system leverages digital technology to identify overloaded trucks – the key to highly effective protection of pavement infrastructure.

Take advantage of the world’s highest accuracy

World’s most accurate WIM system delivers weighing precision of up to ± 2% for gross vehicle weight (in ideal road conditions), from walking pace to racing speeds
OIML R134 certification for accuracy class F5 from the Swiss Federal Institute of Metrology (METAS) provides independent proof of performance – making national type approvals easier
Best detection rate ensures automatic penalization of the maximum number of overloaded vehicles via direct weight enforcement

OIML certificate

Benefit from innovative Lineas Digital sensors

The core elements of the new platform are Lineas Digital WIM sensors – the world’s first fully digitized quartz piezoelectric sensors
With over 60 embedded sensing elements, Lineas Digital generates more data than any other WIM sensor on the market
Lineas Digital is backed by Kistler’s proven track record of over 25 years in quartz piezoelectric sensor technology
Modular design covers all lane widths and fits all types of pavement

Manufactured to highest quality standards

Every sensor is 100% tested and factory-calibrated

Reliable quartz technology - over 100,000 sensors sold worldwide

Minimal road damage with only small slot in the pavement

Low installation costs without the need for heavy machinery

Long service lifetimes backed by Kistler’s 30 years of experience

Fast, minimally invasive installation

Safe transmission of data and power with minimal cabling efforts
No safety risks due to flying parts - wear-free even with snowplows in operation
Fast installation times reduce the demand for road closures
Flexible layout options available to match accuracy requirements

Reliable data acquisition and processing system

Reliable hardware (PoE switch, industrial PC and router) meets the highest industrial quality standards
Electronic devices are part of a certified measuring chain, and are configured to achieve maximum performance
Components are available separately, in DIN-rail configuration or in a fully prewired back panel for easy on-site installation

Versatile customer interfaces

Advanced user-friendly, web-based GUI provides access to all available data records
Standard interfaces allow simple access to data in machine-readable formats
Easy integration into any higher-level systems or customer networks is guaranteed via:
- Pull communication: secured REST API
- Push communication: Ethernet data stream via webhooks

Gain access to cutting-edge digital features

Road safety can be improved by detecting single, dual, flat, mismatched, and missing tires.

Automated tire screening

Delivers tire type information (dual/single) and detects underinflated or flat tires
Enables tire screening with no need for additional software or tilted sensors

Interlane driving

Delivers correct weight measurements and reliable data – even when vehicles switch lanes at high speeds

Smart road calibration

Each quartz crystal within a Lineas Digital WIM sensor can be calibrated separately. This compensates for the influence of varying road properties across the lane, so highly accurate results are guaranteed in all driving positions

System status monitoring

Continuous health status monitoring assures users that the system is consistently operational
Early detection of potential issues minimizes disruptions to operation

A solution that’s also ideal for many applications beyond WIM

Direct weight and tire enforcement

Pre-selection of overloaded vehicles

Infrastructure design and maintenance of roads and bridges

Research and academic purposes

Watch our Success Stories

The Institute of Highway Engineering at Germany’s RWTH Aachen University chose Kistler’s KiTraffic Digital for their pioneering ‘Digital Twin Road’ research project
In 2023, ten Lineas Digital sensors were integrated seamlessly into Germany’s busy A1 highway – with no need for special road preparation or repaving
A special sensor layout was designed exclusively for this project – highlighting Kistler’s commitment to offering flexible layout options and meeting customers’ needs

A7 motorway (Switzerland)

The Traffic and Lake Police of Switzerland’s Thurgau canton rely on the KiTraffic Digital Weigh In Motion (WIM) system – the world's most accurate Weigh In Motion system – to boost the efficiency of commercial vehicle overload inspections at the Kefikon site.
The solution was installed on Switzerland’s A7 motorway at the end of 2020, followed by comprehensive certification in 2021. It was later extended to cover both directions of travel as well as all lanes including the hard shoulders.
By precisely checking the axle loads and total weight (deviation: ≤2.5%) of vehicles moving at speeds between 10 and 130 km/h, the WIM system ensures efficient preselection of overloaded trucks and vans.
