IRD to maintain commercial vehicle enforcement systems in Virginia

69 International Road Dynamics (IRD) is to use weigh-in-motion (WIM) technology to help maintain commercial vehicle enforcement solutions in the commonwealth of Virginia, US, over a two-year period.

The scope of the $4.2 million maintenance and support contract also includes the deployment of IRD’s road side and in-station electronics and computer systems. The company will also use automated vehicle identification equipment, variable message signs, vehicle tracking systems, overview cameras, vehicle dimensioning systems and vehicle classification systems.

IRD’s technology is being used on eleven active commercial vehicle enforcement mainline and ramp systems owned by the Virginia Department of Motor Vehicles. These systems are located at the Suffolk, Bland, Carson, Alberta, Stephens City, Troutville, Dumfries, and Sandston weigh stations.

The mainline systems operate at highway speeds and screen commercial vehicles on interstate, primary or secondary roadways as they approach the inspection station. The in-road sensors send a signal for vehicles which are overweight or in violation of operation regulations to exit to the inspection station ramp. Compliant vehicles are signalled to bypass the inspection station.

The ramp systems operate at lower speeds and carry out a similar process by screening commercial vehicles at the entrance of the inspection station.

IRD's contract comes with renewal options for up to eight successive one-year periods.

Earlier this month, IRD won a contract to use its WIM %$Linker: 2 External <?xml version="1.0" encoding="utf-16"?><dictionary /> 0 0 0 link-external sorting system false http://www.itsinternational.com/categories/utc/news/ird-to-install-wim-sorting-system-in-south-dakota/ false false%> to help protect road infrastructure in the US state of South Dakota.
