Applying the HDM-4 Model to Strategic Planning of Road Works

Today, HDM-4 software is managed by a consortium of organizations, including the World Bank, PIARC, and developed by the UK’s TRL (Transport Research Laboratory). Version 2.0 and later releases have added climate change modeling, vehicle operating cost updates, and integration with GIS. – Enter road ID, geometry, surface type, and initial IRI

HDM-4 operates through five interconnected modules:

This level focuses on evaluating individual road sections or specific projects. It involves analyzing alternative maintenance and rehabilitation strategies (e.g., overlay vs. reconstruction) to determine the most economically suitable option. This is crucial for urban road health monitoring and designing improvements for rural roads. 2. Programme Analysis Version 2

: Developed in the 1980s by the World Bank to focus primarily on developing countries.

The software performs a comprehensive cost-benefit analysis, calculating the Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR) of proposed projects. 4. Optimal Maintenance Strategy

Focuses on the prioritization of a defined list of candidate road projects into a multi-year rolling work program.
