DYNAX® Toll Treadles
Treadles for axle detection
Treadles for axle detection
DYNAX® unibody treadles are designed for axle detection and counting on a roadway, regardless of vehicle speed. One to four replaceable DYNAX® Axle Sensors per lane are employed to detect directional movement and provide highly accurate data.
Virtual Weigh Stations
Weigh-In-Motion systems for enforcement and data.
Weigh-In-Motion systems for enforcement and data.
Virtual Weigh Stations (VWS) are Weigh-In-Motion systems that provide vehicle records for enforcement, traffic surveillance and/or data collection in real-time over a computer network connection to a laptop, tablet, mobile device or workstation computer.

Improving truck safety is important to everyone involved in transportation - from enforcement agencies to commercial carriers. That’s why International Road Dynamics has developed TACS - The Tire Anomaly and Classification System. TACS is an in-road sensor technology that screens vehicles for tire anomalies in real time and at highway speeds.TACS identifies flat, missing or mismatched diameter tires on a dual tire set. Any of these conditions is a high safety risk.

AACT Powered by VectorSense™ for Toll Systems
The VectorSense™ Tire Sensor Suite can be used to improve toll audit systems. By sensing the tire footprint at any point along the sensor, VectorSense™ provides lane position data and track width. This data can be used by toll system integrators to ensure greater accuracy of classification, protection from incidental counts, and elimination of “missed” vehicles due to lane straddling.
