Toll Treadles

IRD DYNAX® Treadles are speed independent axle sensing systems that consist of sensors mounted in a metal insert installed directly into a treadle frame in the road surface. Removable clamping bars secure the DYNAX® Sensors. This design eliminates the need for subsequent roadway excavation to replace sensors, making it ideal for use in toll and traffic monitoring applications.
