The Tire Anomaly and Classification System (TACS) shall support the screening of commercial vehicles at highway (up to 100mph) and ramp speeds (down to 1mph) at weigh station facilities to identify those vehicles which are unsafe due to missing or underinflated tires. In addition, TACS supports the identification of vehicles which are using wide based tires (super singles) and detects single/dual tire configuration for enhanced classification. The system identifies vehicles which meet these criteria and shall provide the ability for station operator(s) to select these vehicles for inspection.
TACS shall consist of the following components:
- In-Road Sensors: for tire detection and measurement, for vehicle classification in accordance with federal and/or local classification schemes, for verifying that a vehicle is properly positioned in a lane and for determining speed, axle width and vehicle length
- Roadside Electronics: to capture information from the In-Road Sensors and pass this information to the weigh station for use by weigh station operations
- Weigh Station Work Station, Software and Graphical User Interface (GUI): to present information to weigh station operators and support their setting of commercial vehicle screening criteria based on data provided by TACS
TACS shall be capable of operating as a standalone system or to be integrated into other existing weigh station screening systems using other technologies, including weigh-in-motion, electronic screening (such as license plate readers (with or without optical character recognition), transponders, USDOT readers, HazMat readers, etc.), vehicle dimensioning systems, vehicle tracking systems, etc.
