RSS69 International Road Dynamics. (IRD) has been awarded a US$1.345 million contract to provide a high speed weigh-in-motion (WIM) and verification system for a new commercial vehicle enforcement facility (CVEF) in Solano County, California. This system will be used by local enforcement personnel for selecting and directing commercial vehicles into the CVEF and by 3879 Caltrans for traffic planning purposes.

IRD will supply an integrated system including its leading single load cell and bending plate WIM scales with its state of the art iSINC controller electronics. The traffic data information collected by the system is essential for pavement studies, highway monitoring, capacity studies, accident rate calculations, and analysis of truck transport practices.

Historically, the New Zealand Transport Agency (NZTA) (formerly Transit New Zealand) has faced challenges in communicating effectively with road users, its customers, about highway-related events or incidents in a timely, accurate manner.

    Dave Marples of Technolution argues that the continuing development of tolling-specific onboard equipment is leading us up a blind alley. We should, he says, be looking to realise universal platforms with universal application. The near-future automobile contains information systems of a sophistication to rival a jet airliner of only a few years ago, yet is 'piloted' by a considerably less well-trained individual of highly variable mental and physical capacity, and operated in a hostile, unpredictable and p
