International Road Dynamics (IRD) has been awarded a $10.2m continuous traffic monitoring (CTM) contract by Hawaii Department of Transportation (HDoT).

The five-year deal will see IRD collect traffic volume, speed, vehicle classification and weight data.

There are currently 91 CTM sites in operation, with more to be added, and IRD will be responsible for the operation, data collection, data reporting, maintenance and repair of them all, along with additional equipment installation. 

HDoT is to convert one existing CTM site per year into a video-based vehicle classification site during the term of the contract, with IRD supplying the iTheia AI classification system.

Existing HDoT Weigh in Motion sites have been equipped to function as virtual weigh stations to provide per-vehicle data and around 12 stations have overview cameras to produce images that will be made available with real-time data and reports.

Data from the CTM systems will be used for traffic planning, noise studies and changes in highway travel patterns.

Chuck Myers, CEO of Quarterhill, says: "Long-term relationships, such as the one we have with HDoT, provide us with a solid base from which we can introduce new enforcement solutions that further help customers meet their transportation management goals."

    Here’s why WiM is value for money
    Weigh in Motion systems are not new. What is new is their ability to collect more data and – importantly – more accurate data about axle loading and vehicle weight. Despite the obvious benefits, including safer highways and possibility of automated legal weight enforcement, obstacles remain for faster uptake.

    Weigh in motion technology aids overweight vehicle reduction
    Innovative use of truck weighing technology is growing as strategies aimed at reducing numbers of overweight vehicles gather momentum. Business is generally good at present in the truck weighing sector in general, and weigh-in-motion (WIM) technology in particular, according to leading suppliers of systems serving to help reduce overloading. Strategies aimed at deterring excessive truck loading – cutting damage to road networks and risks to safety – vary considerably worldwide, with some governments draggin

    IRD complements WIM with tyre under-inflation detection
    To complement its existing WIM offering, IRD has introduced a system to detect under-inflated and flat tyres at highway speeds. Tyre inflation pressure has both safety and economic impacts for road users and none more so than with commercial vehicles. An underinflated tyre has decreased directional control, increased risk of catastrophic failure, and negatively impacts tyre life and fuel economy. In June 2014 the USDOT published Large Truck and Bus Crash Facts 2012 in which the Federal Motor Carrier Safety
