New Nortech IR200 provides intelligent vehicle loop detection

Today's traffic systems thrive on data, which is why Nortech Detection is debuting its IR200 intelligent vehicle loop detector at the ITS World Congress. Designed for motorway use, the IR200 collects, stores and reports multi-lane traffic data derived from 32 loops (or 16 lanes in speed measurement mode) at vehicle speeds to 200km/h. The IR200 incorporates incident detection capability implemented at the roadside. Using the TRRL HIOCC algorithm, the equipment monitors traffic occupancy per lane on a seco

Today's traffic systems thrive on data, which is why Nortech Detection is debuting its IR200 intelligent vehicle loop detector at the ITS World Congress. Designed for motorway use, the IR200 collects, stores and reports multi-lane traffic data derived from 32 loops (or 16 lanes in speed measurement mode) at vehicle speeds to 200km/h.

The IR200 incorporates incident detection capability implemented at the roadside. Using the TRRL HIOCC algorithm, the equipment monitors traffic occupancy per lane on a second-by-second basis and provides traffic incident alarms calculated from configurable alarm variables downloaded from the host computer.

'Smarter' TD664 vehicle detectors incorporate AFS (automatic frequency selection) on each four channel card, evaluating multiple possible frequency shift selections and automatically selecting the best frequency setting for each loop on start-up.

The IR200 upgrades Nortech's previous system from serial communication to ethernet, offering RS232, ethernet and USB ports, and a web browser interface.

“The web browser interface enables the operator to access the system remotely from anywhere,” said Cyril Farrow, technical manager, Nortech Detection. “The operator no longer has to be on site. They can do fault diagnostics and reconfigure IR200 from the office, which is a major advance over our previous system.

“Remote access can save hours on any failure, especially intermittent failures, where the tech would otherwise have to sit for hours waiting for something to go wrong,” he said.

The IR200, based on the same technology used in 3M automatic vehicle classification (AVC) solutions, is compliant for all Australian traffic systems, and CE mark certified for European and international use.

This is combined with a SmartMonitor interface to a CMU-212 cabinet monitor unit (CMU). The company says it designed the new ADU because many transportation agencies no longer supply their personnel with laptops for connecting with instrumentation in on-street cabinets.

    Sensys Networks’ new FlexConnect synchronous data link control interface (SDLC) module for TS2 traffic signal controllers, provides an SDLC interface between the controller and the company’s wireless vehicle detection system (VDS). Traffic detection events are signalled from VDS to the TS2 controller in conformance with the NEMA TS2-2003 specification and using FlexConnect and eliminates the need for interface cards without requiring available slots in traffic signal cabinets. The unit supports 64 channe
