As a dynamic road profiling device, Accelerometer Established Inertial Profiling Reference (AEIPR) method has cost effectiveness and high reliability for road profiling. This paper describes at first the improved double integration algorithm that is tile major problem to be solved in the AEIPR method. Road profiling software 'Road Profiler' is developed on the basis of tile improved double integration algorithm. 'Road Profiler' software consists of 3 modules of data acquisition, signal processing and evaluation. Road profiling tests are performed on tile special test tracks and some public roads. The test results measured using AEIPR method are shown and evaluated.
