HI-TRAC 100

The HI-TRAC 100 high-speed weigh-in-motion and traffic data collection system provides a low cost means of recording vehicle classification and axle load data without interruption to traffic flows. In the standard configuration, two piezo electric sensors and one induction loop are installed in the highway per lane of detection. The piezo electric sensors measure axle speeds and inter-axle spacing. The induction loop detects vehicle presence and measures the vehicle length. If Class 1 piezo electric sensors are employed, axle weight data can also be attained.

Incident detection and event monitoring functions can be incorporated along with message sign activation and CCTV interface for text insertion and automatic number plate recognition (ANPR).

The system can be used as a statistical data gathering device to record the pattern of highway traffic loading. It is also employed as a screening weighbridge to identify overloaded vehicles in the traffic stream. In the latter configuration the output from the system controls traffic signals and diversion signs to intercept overloaded vehicles and direct them off the highway.

The HI-TRAC 100 is complimented by the HI-COMM 100 software package. HI-COMM 100 provides data retrieval via modem and laptop as well as data analysis facilities and system diagnostic functions.
