International Road Dynamics is an
intelligent transportation systems company that improves transportation
efficiency and highway safety by using roadside electronic screening systems to
detect, measure, and analyze. Here’s how it works. Trucks and other commercial vehicles approaching an inspection station are
checked at highway speeds for compliance with regulations. Weigh-in-motion scales
and laser dimensioning scanners check for vehicles that are overweight or over
dimension. Tire anomaly sensors check for under-inflated, overinflated, damaged or
missing tires that could pose a safety hazard. License plate readers, USDOT
readers, transponders and other automatic vehicle identification technologies
identify trucks. A HAZMAT placard reader identifies vehicles transporting
hazardous goods. The in-station system performs screening operations using
credential information from federal, state and local databases. Trucks that
are within acceptable weight and dimensions, and deemed a low safety risk, are directed by message signs and transponders to bypass the weigh station.
Other trucks, and those randomly selected, are directed by roadside message signs
and transponders to a ramp where they can be rescreened
at slower speed, and their brakes and tires are checked using infrared cameras.
Problem is detected. Trucks are only weighed on a static scale, or directed to
an inspection bay, if a problem is detected. A tracking system monitors
trucks, follows their notifications, and generates alarms in case of unauthorized bypass. Automated vehicle inspection protects
infrastructure, saves time and money, reduces greenhouse emissions, and
enhances safety while improving transportation efficiency. To learn more
