However, there is no proper and complete certification process and methods for inertial profilers. In addition, the operators do not have enough professional knowledge and skill to measure the pavement smoothness correctly. Therefore, the operational quality in Taiwan is lower than other countries such as America and Canada. For the sake of increasing the quality of measurements, the certifying process for the inertial profiler and guideline of operator training has been developed in this study. First, the certification standards in Taiwan and other countries were collected. Then the certification process for the inertial profiler was established following the AASHTO PP49 specification. The certification includes two main procedures which are the calibration procedure in the laboratory and the field test procedure. In this study, a laser-type inertial profiler was certificated in the specific road. Furthermore, the three methods in the AASHTO PP49 specification were utilized to evaluate the repeatability and accuracy of the inertial profiler. During the field test of the certification procedures, operational factors are unavoidable source of error. Therefore, the variation in speed and transient acceleration as well as the lateral positioning were discussed in order to understand the vehicular operating conditions during the procedure. In addition, the guideline of operator training was established that was based on standards of smoothness and inertial profiler certification. The handbook of operators training includes the smoothness index, devices for smoothness measurement, certification process, factors affecting inertial profiler measurements and signal process. By developing the handbook and guideline of operator training, the quality of smoothness measurements utilizing inertial profilers can be promoted in Taiwan.
