HIGH SPEED WEIGH-IN-MOTION • LOW POWER / LOW COST SOLUTION WITHOUT COMPROMISING CAPABILITY • IDEAL SOLUTION FOR BRIDGE PROTECTION SCHEMES • UP TO 2 LANES OF MONITORING WITH 8GB DATA STORAGE
OVERVIEW TDC’s HI-TRAC® range of high speed WIM systems are installed along highways to weigh vehicles at normal highway speeds (20-120kph) and detect, count and classify vehicles from 5kph-200kph. They can achieve accuracies from COST 323 Class A(5) +/-5% Gross Weight to COST 323 Class C(15) +/-15% Gross Weight at 95% confidence depending on requirements. The HI-TRAC® EMU3 WIM & Classification System The EMU3 is both a highly accurate Weigh-in-Motion and a real-time Vehicle Classification System that uses low-cost renewable energy supplies. This makes the location of roadside installation flexible rather than being dictated by the availability of power supply connections. Its integrated communications module with GPS and unique sensor interface card enable accurate vehicle, Weigh-in-Motion and
classification data to be sent in real time every five minutes from the roadside to the command centre. In practice, the system is able to operate wherever a mobile phone service is available, and can record motorcycles at the same time as weighing a Heavy Goods Vehicle. The HI-TRAC® 100+ WIM This system can connect to eight lanes of WIM sensors and has a long and excellent track record. This is being used in Saudi Arabia to help the Ministry of Transport protect their bridges and highways from the damage caused by overloaded vehicles (see case studies for more info). TDC has integrated Kistler Lineas® Quartz WIM Sensors with the HI-TRAC® 100+ WIM/ANPR System to provide the accuracy needed to identify and weigh vehicles within very high enforcement tolerances.
