 Summary:
 The HDM-4 system is a software tool that is used to appraise the technical and economic aspects of road investment projects. It has become widely used as a planning and programming tool for highway expenditure and maintenance standards. Since the model simulates future changes to the road system from current conditions, the reliability of the results is dependent, among the remaining elements, upon how well the predictions of the model fit the real behavior. That is why application of the model involves an important calibration step to local conditions and environment.
