The Highway Development and Management Model Four, Version 2.0, (HDM-4) is a software application which serves as a primary tool for road administrations in the analysis, planning, management and appraisal of road maintenance, improvements, and investment decisions.
HDM-4 supports business-level decisions, such as technical and economic appraisals of road investment projects, standards, and strategies. The software helps determine the most economically efficient maintenance and improvement strategy for a road network.
However, it is twenty years since the last major upgrade, and the HDM 4 software is missing some of the coverage and functionality demanded by clients in the 21st Century in terms of:
- Climate Change;
- Resilience;
- Greenhouse gas emissions;
- Road safety benefits;
- Tertiary roads;
- Changes in the Vehicle Fleet;
- Wider economic impacts;
- Indexing of the real value of time and life; and
- Changing to a cloud-based service.
Å·ÃÀÈÕb´óƬ and its partners ¨C The Asian Development Bank, the United Kingdom Foreign Commonwealth Development Office, the European Investment Bank, and the World Road Congress (PIARC) ¨C are working together to upgrade HDM-4, with a new version slated to become available in 2025.
The HDM-4 Upgrade program is being made possible by the financial support from the Japan-Bank Program for Mainstreaming DRM in Developing Countries, which is financed by the Government of Japan and receives technical support from the World Bank GFDRR Tokyo Disaster Risk Management Hub.
