Banks (World Bank, ADB, AfDB) require a quantified economic justification for any loan. HDM-4 provides the standard reporting format. For a 50 km rural highway, the software will prove (or disprove) that an asphalt overlay yields a 22% EIRR versus a cheaper surface treatment.
| Software | Focus | Integration with HDM-4 | |----------|-------|------------------------| | dTIMS (Deighton Total Infrastructure Management System) | Network-level optimization | Can import HDM-4 deterioration models | | RoadAssist (World Bank) | Simplified project appraisal | Lighter version of HDM-4 principles | | Pavement LCCA (FHWA) | Lifecycle cost only | Less comprehensive than HDM-4 | | VOC Tools (PIARC) | Vehicle operating costs only | Used as a sub-module within HDM-4 | hdm-4 software
For an agency managing 10,000+ km of roads, the question is not "which road project is good?" but "which 20 projects across the network yield the best aggregate outcome?" HDM-4 uses priority ranking and budget optimization to sequence M&R activities over a 10- to 20-year planning horizon. It can answer: Banks (World Bank, ADB, AfDB) require a quantified
This is used for specific road sections to analyze engineering alternatives in detail. For an agency managing 10,000+ km of roads,
