IRD (International Road Dynamics Inc) has achieved the milestone of more than 10,000 global installations of its Bending Plate Scale (BPS) WIM (weigh-in-motion) system. Customers have included federal, state, provincial, city and municipal government agencies, private corporations, toll authorities, as well as the high-profile US Federal Highway Authority (FHWA) and Transport Canada’s LTPP (Long Term Pavement Performance Program). The Bending Plates have been installed in sites that endure all types of weather conditions – from the extreme cold of Canada’s north and Chile’s south, to the excessive heat of deserts in the Middle East, Latin America and Africa.
The BPS product is renowned for weighing and screening at truck weighstations and IRD virtual weighstations, toll by weight (WIM@Toll), and traffic data collection systems. The company’s +10,000 BPS installations make up over half of its WIM technology placements. Other WIM technologies supplied by the company include Single Load Cell (SLC) scales, Lineas Quartz sensors, Piezoelectric sensors and Slow Speed WIM (SSWIM) scales. In 2003, IRD acquired the Germany-based PAT Traffic, which also distributes the BPS system.

IRD says that BPS provides long life, excellent stability, reliability and accuracy over a wide range of environmental, traffic density and speed conditions. The IRD-PAT system satisfies the ASTM E1318-09 Standard Specifications for Highway Weigh-in-Motion (WIM) Systems and performance requirements for Type I WIM systems, and the COST 323 ‘Weigh-in-Motion of Road Vehicles’ performance requirements for Type B and Type C WIM. Available to suit all lane widths, the BPS can be installed in asphalt, Portland cement or concrete pavements. Furthermore, IRD’s WIM technologies can be integrated with its iSINC, and other traffic data systems, to provide advanced truck weighing, traffic data, traffic safety, toll collection, and security and access control systems.
