ABSTRACT:
A portable Dynamic Testing Vehicle able to test for surface friction, drag, and travel distance, through contaminates accounting for longitudinal and lateral acceleration. The DFT is completely self contained with on board power supply, control unit, and water tank. The DFT has a high profile and long chassis to facilitate ease of movement and measurement at up to 100 km/h. Data obtained is transferred through the use of a wireless data transfer to a small handheld personal computer and then to a desktop computer where data is analyzed and or archived via specifically written software.
