HDM 4 MODEL SOFTWARE
The Highway Development and Management Model (HDM-4) Version 1.3 was released in January 2002 which is the recommended software for evaluating highway investment options. Features: Appendices Figures References addition, the HDM-4 software modules can be replaced, if necessary to customize their use within existing road agency management information systems 3-4.Location: Arusha International Conference Centre, Tanzania At the end of the course, the trainees will know the theoretical basis of the HDM4 model and will be able to use it : - to define an optimal strategy for.First Road Transportation Technology Transfer Conference in Africa.

Tanzania Ministry of Works Holland House Avenue, P.O. Local adaptation and calibration of HDM-4 models can be achieved by specifying default data sets that represent pavement performance and vehicle resource consumption in the country where the model is being used. Standard data import and export facilities are provided for linking HDM-4 to various database management systems. HDM-4 is designed to be used as a decision support tool within a road management system. HDM-4 incorporates 3 dedicated applications tools for project level analyis, road work programming under constrained budgets, and for strategic planning of long-term network performance and expenditure needs. In addition to updating the HDM-III technical relationships for vehicle operating costs and pavement deterioration for flexible and unsealed pavements, new technical relationships have been added to model rigid concrete pavement deterioration, accident costs, traffic congestion, energy consumption, and environmental effects. The scope of the new HDM-4 has been broadened considerably beyond traditional project appraisals, to provide a powerful system for the analysis of road management and investment alternatives. The Highway Development and Management Tool known as HDM-4 is the successor to the World Bank Highway Design and Maintenance Standards Model (HDM-III).
