Loop Counter Classifiers utilise two inductive loop sensors per traffic lane and provide vehicle counting and classification to Euro 6 (or similar) vehicle classification specifications. TDC offer a number of loop counter classifier solutions; the HI-TRAC 110, the HI-TRAC EMU, the HI-TRAC TMU2 and the HI-TRAC UTC-L. Communication options include GPRS, GSM, USB, Bluetooth, RS232 and Ethernet TCP/IP.

The HI-TRAC® range of Loop Counter Classifiers use established loop sensor technology with TDC’s Advanced Loop Profiling function to detect mixed traffic recording vehicle speed, length, classification, gap and headway. The systems can be used as a statistical data gathering device to record the pattern of highway traffic as well as a means of event monitoring and incident detection.

TDC Systems advanced vehicle straddling algorithms mean volumetric detection rates in excess of 99.5% are achievable.

The HI-TRAC® TMU2 offers connectivity up to 16 lanes and incorporates embedded Ethernet with TCP/IP stack, VPN and FTP as well as extensive 4Gbytes data storage and thus provides high-end functionality at a reasonable cost. The system is 19 inch rack design and may be powered from either mains supply or solar panel and associated battery & charge regulator.

The HI-TRAC® 110 offers connectivity up to 8 lanes and is used extensively in shadow tolling applications. The system is 19 inch rack design and may be powered from either mains supply or solar panel and associated battery & charge regulator.

The HI-TRAC® EMU is a low power traffic data collection system with upgradeable options configurable to:

• Loop Volumetric Counter
• Loop Speed and Length Classifier
• Loop Profiling Classifier
• Axle Classifier with Bicycle and Motorcycle Detection
• Weigh-in-Motion System
• Event Monitoring

The HI-TRAC® EMU can be powered from either mains supply or solar panel and associated battery & charge regulator.

The UTC-L is powered by a small, sealed lithium battery mounted externally to the unit. The UTC-L battery life for standard operation is 1 year. The UTC unit is sealed to IP68 and can be installed into either a small roadside pillar or post or into a small subsurface chamber.
