Traffic Products Exhibit in Brisbane
23 October 2009
2nd Annual Road and Transport Engineering - Brisbane
25th - 27th November 2009 * Novotel, Brisbane
Nortech is the Exhibition Sponsor for this event in Brisbane in November.
This Conference is dedicated to Identifying methods of procurement and financing of major motorways projects.
The Conference will also provide an opportunity for feedback from current Queenland ITS Projects including the Gateway Upgrade, Airport Link and the the Darra to Springfield Transport Corridor Project. The speakers are from Department of Transport and Main Roads, Queensland Motorways and the Major Contractors for these projects. Technical presentations include Intelligent Transport Systems (ITS) free-flowing tolling technologies.
New TD724 Vehicle Detector
20 April 2009
Nortech have released the new TD724 Vehicle Detector being the latest in the range of 4 channel vehicle detectors developed for high-end Motorway Traffic Detection.
The TD724ID is a high performance, 4 channel, microprocessor based card detector complying with Eurocard standards.
Features incorporated on this model make it the most advanced vehicle detector available.
The TD724ID is used with the IDR112 Vehicle classifier and for high -end IDRIS tolling applications.

Piezo vs Loop Axle Detection
12 November 2008
Vehicle Classifiers from Nortech, based on IDRIS technology are highly accurate traffic profile classifiers that combine sophisticated data processing algorithms with loop based axle counting using specially designed and patented IDRIS loop configurations. Axle detection enhances the profiling capabilities of the IDRIS Technology.
Nortech has now developed a piezo based axle detection card which has enabled IDRIS technology to use alternative sensors for data collection applications. This means IDRIS axle classification accuracy from existing piezo sites!
IDRIS Delves Deeper
22 October 2008
A major benefit of IDRIS automatic vehicle classification (AVC) technology as applied in the Nortech IDR112 classifier is the use of inductive loop axle sensors. Other technologies that rely on piezo axle sensors are far more prone to traffic damage and failure of the roadway surface due to sensor installation.
Owing to this damage caused by installing loops and sensors in the road surface, a practice of installing loops in sub-surface layers, particularly on new road surfaces, is now becoming the rule.
Installing loops below the wearing course enables the milling of road surfaces without damaging loop arrays.
With recent enhancements to the Nortech vehicle detectors used in the IDR112 classifier, IDRIS axle detection loops can now be installed in sub-surface layers.
New IDRIS based IDR112 Vehicle Classifier
12 September 2008
The IDR112 Vehicle Classifier is a new development from Nortech resulting from the combination of the latest vehicle detector hardware from Nortech and sophisticated software known as IDRIS.
The IDR112 Vehicle Classifier is able to classify traffic into 12 different vehicle types in accordance with Austroads Vehicle types, based on vehicle lengths and axle arrangements.
The standard model has eight detector cards, sufficient for up to eight traffic lanes.
The vehicle and axle detection is based on inductive loops without the need for piezo axle detection.
(Piezo detection option available)
The accuracy of this equipment exceeds the specified accuracy requirements.
IDRIS © capabilities for the IDR112 Intelligent Vehicle Loop Detector
10 June 2008
A conventional Nortech IR100 vehicle detector rack is designed to collect vehicle traffic data from multiple traffic lanes on motorways and arterials. The data normally collected relates to traffic volumes, vehicle speeds, vehicle lengths lane occupancy and traffic headway.
Conventional loop detectors while accurate for traffic statistics purposes are subject to small errors resulting from straddling vehicles and poor lane discipline. Also they are less ideal when used to collect data in congested conditions with associated close following distances and stopped vehicles.
These errors can be eliminated when a signal processing technique is applied to continuously extract the dynamic inductance changes caused by a vehicle passing over the loop. These changes are analysed to determine the number of axles, vehicle type, speed and direction of vehicle movement under conditions ranging from free flowing to stop and go traffic or total congestion.
The algorithms and data processing that have been developed to accurately handle real traffic conditions are collectively known as IDRIS
IR100 Incident Detection at the Roadside
10 April 2008
The Nortech IR100 vehicle detector rack is designed to collect vehicle traffic data from multiple traffic lanes on motorways and arterials. The data normally collected relates to traffic volumes, vehicle speeds, vehicle lengths, lane occupancy and traffic headway.
Most traffic monitoring systems of necessity implement a congestion algorithm based on loop occupancy to determine changes in traffic flows that result from a traffic incident. This information is used to provide immediate system alarms when traffic incidents occur. The congestion algorithm requires that traffic data is compared every second to determine changes in traffic flow.
The latest generation of Traffic Monitoring equipment from Nortech Detection now provides the additional processing power to undertake the incident detection task at the roadside where the traffic data is immediately available.
