Training Session 10 - HDM 5 Software: Transport Forum 2024

For over 30 years, the Highway Development and Management (#HDM-4) analysis framework and tools have provided the international benchmark for evaluating road #investments at the project, network and strategic level. Combining models for predicting the performance of both road deterioration and road user effects, HDM-4 has provided the basis for justifying road investments in well over 100 countries.
However, over the past 30 years there have also been some significant changes in terms of vehicle technology (e.g., electric vehicles, etc.), new pavement construction and maintenance techniques, and a greater need to understand greenhouse gas emissions, climate resilience and related factors. To this end, HDM-5 has commenced with the research into the upgrades required to take the foundation of HDM-4 and make it fit-for-purpose for the next several decades.
This workshop, held last 17 May 2024, explored the changes proposed for HDM-5, along with ensuring that users of HDM-4 (either users of the output or direct software users) are suitably informed of the capabilities and limitations of the system, and seek views on future needs of DMCs in this regard.
