Collect road usage data with a high-speed automatic vehicle counter and classification system without interrupting traffic flow.

  • Operate up to 16 high-speed lanes of automatic vehicle counter/classifying (AVC)
  • Achieve vehicle classification in excess of 99.5% accuracy
  • Support a variety of unobtrusive, in-road sensor arrays


Governments and traffic authorities center their goals on stimulating sustainable, safe transportation while preserving infrastructure. Weigh-in-motion combined with automatic vehicle counter and classification solutions collect road usage data without disrupting traffic flow, while monitoring and enforcing fair and sustainable use.

The HI-TRAC® TMU2 is a high-speed traffic data collection system that records vehicle classification data without interruption to traffic flow. It supports a variety of in-road sensor arrays (loop-loop, loop-piezo-loop and loop-piezo-loop- piezo) providing loop profiling and axle classification functionality.

When utilized as a statistical data gathering device, the system can:

  • Record the pattern of highway traffic
  • Provide event monitoring and incident detection

Installed in the pavement, the HI-TRAC TMU2 interfaces to both piezo-electric and inductive loop sensors and also configures into a high-speed weigh-in-motion system. Q-Free’s advanced vehicle-straddling algorithms mean that volumetric detection rates in excess of 99.5 percent are achievable.

Built to withstand a long outdoor life, the HI-TRAC TMU2 is sealed to IP65 and, therefore, is protected against solid objects, dust, and rain. The HI-TRAC TMU2 is powered by either a mains supply or a solar panel and associated battery and charge regulator. Communicate via internal or external GSM/GPRS/2G/3G/4G for data download, diagnostics, and configuration
