GUIDELINES ON APPLYING AND CALIBRATING THE HDM MODEL TO LOCAL CONDITIONS

An approach is developed for calibrating a universal pavement management model to local conditions. The Highway Development and Management Model (HDM) has been used in various forms in many countries for a range of applications, from feasibility studies to pavement management applications. As a general but empirically based model, there is a need for calibration to ensure that the predictions reflect local conditions. Three levels of calibration have been established: Basic Application, Calibration and Adaptation. Since the potential number of data items and parameters is large, an analysis was undertaken with HDM to rank the impact of data and model parameters on the model output. On this basis parameters have been assigned to four sensitivity levels, so that collection efforts and the required accuracy can be matched to the influence of the parameter.
