HDM

Information on HDM-III, HDM-4 and their application.

Presentation at the launch workshop for the proposed International Study of Road Asset Management and Models in Washington D.C., May 2015.

Presentation on how HDM-4’s pavement deterioration and road user effects model work.

Presentation describing the data collection requirements for HDM.

Comprehensive book on the modelling of road user and environmental effects. It covers all aspects from vehcile operating costs to emissins. The models presented here formed the basis for the modelling in HDM-4, although the software does not fully implement the models.

A three-day training course on HDM-4 run in Cambodia covering all aspects of using HDM-4. The modules are:

01: Introduction to HDM-4

02: The HDM-4 Software Package

03: Case Study – Paving a Gravel Road

04: Structure of the HDM-4 Software

05: HDM-4 Analysis Options

06: HDM-4 Bituminous Pavement Deterioration

07: HDM-4 Economic Evaluation

08: HDM-4 Road User Effects

09: Calibration and Validation

10: HDM-4 Unsealed Road Deterioration

Overview of the context in which HDM-4 is used, and to provide participants with a framework by which they can identify how they might introduce or expand the use of HDM-4 in their organisations.

Presentation to the 2001 PMS Conference on how to calibrate HDM-4.
