HDM-4 (Highway Development and Management, Version 4) is a specialized software suite used to investigate the technical and economic viability of road investment projects. It models the interaction between road design, maintenance strategies, environmental conditions, traffic volumes, and vehicle operating costs.
Here is a structured overview of the software, designed for documentation or training purposes. 1. hdm-4 software
Modern HDM-4 versions (v2.2+) include modules to calculate excess fuel consumption and CO₂ emissions due to poor roughness. Agencies now use HDM-4 to justify “green maintenance” – i.e., keeping roads smooth reduces emissions more cheaply than buying carbon credits. HDM-4 (Highway Development and Management, Version 4) is
