If you need a comprehensive and accurate vehicle information resource, Nortech Traffic Roadside Traffic Monitoring Racks are your solution. Easily integrated into other systems or operating as stand-alone products, our elaborate racks are easy to set-up and extremely reliable. Whether required for Classification, Data Recording, Tolling, Incident Detection, Enforcement or more specialized applications - we have a range to fulfill your specifications.


With the Nortech Traffic TD664 inside, the IR200 Intelligent Vehicle Loop Detector is a reliable and accurate vehicle detection system with low maintenance costs. The IR200 collects, stores and reports on multi-lane traffic data comprising of individual vehicle data events or average flow data relating to traffic volume, speed, length category, vehicle headway and percentage occupancy. It can monitor 32 loops (16 lanes) at vehicle speeds of up to 200km/h.

The Nortech ARM9 processor has been designed with ITS applications in mind. It runs an ARM9 CPU mounted into a standard Eurocard sized carrier. It has the ability to communicate with up to 8 detectors via serial communications to provide a vehicle detection sub-system for integration into ITS applications. An external host computer is able to access information by interrogating the processor via the various communications options available on the front panel.

Remote access via our easy-to-use web browser interface allows for rapid configuration, real-time incident detection, real-time viewing of traffic and host communication data, extensive fault diagnostics and logs.

The IR200 uses the TRRL HIOCC algorithm to monitor traffic occupancy per lane on a second-by-second basis and provides traffic incident alarms calculated from configurable alarm variables stored on the IR200 processor.

IR200 is fully compatible with existing IR100 installations and is a simple drop-in replacement.

Typical Usage:

  • Incident Detection.
  • Data Recording.

Nortech Traffic is a technology partner to various OEMs and capable of supplying and supporting the algorithms on offer from these OEMs. The OEM AVC algorithms provide superior accuracy using inductive loop technology, covering both single and multi-lane configurations while accounting for vehicle straddling and high-congestion scenarios. This solution will work in all traffic, light and weather conditions.


  • Tolling: Counts and classifies to mandated requirements by varying toll agencies giving up to a 99.5% accuracy.
  • Shadow Tolling: Accurate vehicle length measurement. Works where there is no culture of conventional tolling.
  • Intelligent Vehicle Detection: Used for bus priority with no "in vehicle" technology required.
  • Data Recording: Classifies according to profile, axle count and configuration, giving up to a 95% accuracy.
  • Speed, Red Light Enforcement and Tunnel Monitoring: Can be used to set off triggers/alerts based on predefined rules, such as speeding, prohibited use of roads and lanes for certain vehicles as well as vehicles travelling in the wrong direction in a lane.
  • Incident Detection: Detects single stopped vehicles in low traffic volumes.

Typical Usage:

  • Enforcement.
  • Incident Detection.
  • Data Recording.
  • Tolling.
  • Special Applications.
  • Urban Intersection Monitoring: Prioritisation.
