: Calculates the Total Transport Cost , which includes both Road Agency Costs (construction and maintenance) and Road User Costs (vehicle operation, travel time, and accidents). Other Notable Features
When a road deteriorates, transport costs spike. HDM-4 accurately calculates how road conditions impact:

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.
The software uses a deterministic approach to input data regarding existing road conditions, traffic volume, and pavement composition to predict future pavement behavior, including pavement performance, rutting , and cracking . Core Modules and Applications : Fuel consumption, tire wear, spare parts, and
Comparing different pavement designs (e.g., rigid concrete vs. flexible asphalt).
However, software alone is not a solution. The organizations that succeed with HDM-4 are those that:
