MOTORWAY TRAFFIC MONITORING SYSTEMS

IR100 Intelligent Vehicle Detector equipment installed at the roadside captures real-time vehicle traffic data..
IR100 equipment employs inductive loop sensors buried in the motorway to collect data on traffic volumes, vehicle speed, length and headway.
Advanced software options offer vehicle profiling to reliably determine vehicle classes and axle configuration.
The IR100 is a vital building block in Intelligent Transport Systems (ITS) applications.

IR100 Intelligent Vehicle Detector

Nortech Intelligent Traffic Monitoring Equipment provides a system to acquire, real-time Traffic Data relating to vehicle volumes, occupancy and speed.
The Hardware making up the "Intelligent Vehicle Loop Detector" unit comprises of a number of modules designed to be accommodated in a standard 19" card cage. They comprise of multi-channel detector cards, the SC600E processor and communications module and a Power-supply and battery charger module.
Outstations are typically installed every 500 metres along major arterials to provide early warning of traffic congestion and accidents

IR100 Incident Detection Outstation

This equipment manages the Incident Detection task at the roadside where the traffic data is readily available. This eliminates the need to provide 1 second occupancy data to a remote processor and greatly reduces the communications overhead with the roadside equipment.
The Traffic Manager retains full control over the incident response with the ability to download the variables associated with the incident algorithm to the roadside on a lane-per-lane basis during initialisation of the equipment.

IR100 with Enhanced Traffic Data Accuracy

For this application the IR100 Incident Rack is equipped with highly accurate 4 channel vehicle detectors and a powerful ARM-9 Processor. This processor is capable of running Linux based applications for advanced traffic data collection.
IDRIS software that has vehicle profile capability is employed to eliminate data inaccuracy due to vehicles straddling lanes, and low speed, congested traffic conditions that cause errors in "standard" loop systems.
IDRIS software achieves volume accuracies of:
"Better than 99.9% count accuracy in free flowing traffic"
"Better than 99% count accuracy in congestion"

IDR112 Vehicle Classifier

Introducing axle counting into the vehicle classification provides more accurate classification of differing vehicle types. By use of additional patented axle loops in the roadway, the IDRIS equipment eliminates the need for multiple sensors such as piezos, treadles and light curtains.
Highly accurate IDRIS software (DR320) provides 12 category AUSTROADS vehicle type classification with >98% accuracy. Other IDRIS software versions can provide even greater accuracies for Tolling applications.
IDRIS accuracy is not dependent on vehicle speeds or congestion which may include stop and go traffic through to free flow. IDRIS accuracy is not influenced by weather conditions.
