Traffic Speed Deflectometer - Measuring Principle

The Traffic Speed Deflectometer measures the velocity of deflection rather than displacement. The measuring of the pavement response is based on advanced Doppler laser technique.

The measurement equipment is placed in the trailer and is connected with the truck, where the operator can add events to the data when measuring using a keyboard.

The measured data makes it possible to report deflection characteristics continuously. The collected data are treated in a dedicated post processing software program.

It is possible to combine the Traffic Speed Deflectometer with other Greenwood road measuring equipments, where such an equipment can take advantage of all the features in the Greenwood multifunction hardware and software package, where it is possible to measure and see all subsystems in a synchronized way both when collecting data and during post processing.
