International Road Dynamics (IRD) has extended its relationship with the US state of Idaho via a new CAN$2.2 million contract.

The company is to supply and install a mainline Weigh in Motion (WiM) and electronic pre-clearance system for Idaho Transportation Department (ITD) on I-84 Westbound at the Declo Port of Entry in Cassia County, southern Idaho. 

IRD’s Single Load Cell WiM scales are used on the project, and licence plate reader and automated vehicle ID systems will be integrated with IRD’s intelligent roadside operations computer to screen vehicles’ credentials and safety statuses against state and Federal databases.

This will reduce congestion by allowing compliant vehicles to bypass the weigh station - something that is particularly useful at peak times.

IRD's Tacs (Tire Anomaly and Classification System) will be used to screen trucks with flat, missing, mismatched or underinflated tyres; they will be removed from the road until the problem is rectified. 
“In addition to improving road safety and protecting roads from damage by overloaded commercial vehicles, this project will improve efficiency and enable IDT to resolve peak-time congestion at the port of entry,” said Rish Malhotra, IRD President and CEO.

“The Declo pre-clearance system will complement the other IRD supplied systems in Idaho and expand the coverage of the state’s network of fully-automated weight enforcement facilities."

"Based on our experience with other Tacs implementations, we expect ITD will also identify significantly more vehicles at this site with serious tyre safety issues that warrant out-of-service penalties, thereby reducing GHG emissions in addition to increasing safety and improving efficiency.”
