How does the weigh station work?
While at the weigh station, the truck will be weighed via rolling scales, which means that the drivers can simply drive over the scale, rather than having to come to a stop. If the truck is under 80,000 pounds, then the driver will get the green light to continue to the freeway.
How do virtual weigh stations work?
“A virtual weigh station is a roadside enforcement facility that does not require continuous staffing and is monitored from another location. Typical hardware deployed at a virtual weigh station includes a WIM installation, a camera system, and high-speed communications for use in real-time truck screening operations.
What is a weigh in motion station?
Weigh-in-Motion (WIM) systems are an array of sensors used to measure various features of vehicles in motion. WIM systems are comprised of not only the electronics and sensors but include just as importantly flat, smooth, and straight roadways.
What are the sensors by weigh stations?
The WIM scale or sensor embedded in the pavement automatically weighs vehicles and provides an estimate of the vehicle’s weight to station personnel for sorting purposes.
Why do trucks go through weigh stations?
Truck weigh stations are important because weighing trucks prevents overweight trucks from going onto highways that cannot handle the heavy load. Trucks that weigh over the regulated weight limit can cause irreparable damage to roads and bridges. Many states collect taxes on transported goods based on weight.
What is a static scale?
Static scales only weigh goods, products or vehicles when they have come to a complete stop. In other words, when there is no longer any relative movement between the goods being weighed and the load carrier. Examples include bathroom scales or platform scales.
Do weigh stations have cameras?
Permanent cameras are fixed on both sides of a lane approaching a weigh station. Photos are taken of both the right and left side of the vehicle, and the images are sent immediately to personnel.
How are trucks weighed in motion?
The scales are typically connected to a single electronic controller that automatically combines the axle weights to get the gross weight. Weigh-in-motion (WIM) – A method that is gaining momentum, WIM uses a series of embedded sensors to calculate the weight per axle as a truck drives over the sensor pad.
What are the scanners before a weigh station?
Thermal cameras scan for bad brakes, automated license plate readers run checks against state and federal databases, and behind it all, law enforcement personnel in the station manage these complex systems to improve road safety. You’ll also hear a Q&A with a veteran law enforcement safety officer.
