HIGHWAY DESIGN AND MAINTENANCE STANDARDS MODEL (HDM-4) PRESENTED BY THE
SAICE TRANSPORTATION DIVISION

DATE: 8-10 JUNE 2010

VENUE: SAICE HOUSE BLOCK 19, THORNHILL OFFICE PARK, BEKKER STREET, VORNA
VALLEY, MIDRAND 

The Transportation Division of SAICE invites you to attend a course on
the Highway Design and Maintenance Standards Model (HDM-4)

The HDM-4 software was developed as part of the International Study of
Highway Development and Management Tools (ISOHDM), sponsored by the
World Bank, Asian Development Bank, Swedish National Road
Administration, DFID, as well as others. The Highway Design and
Maintenance Standards Model (HDM-III) has been used for over two decades
to combine technical and economic appraisal of road investment projects,
standards and strategies and its extended scope (HDM-4) provides a
harmonized systems approach to road management, with adaptable and
user-friendly software tools. The ISOHDM project has had three major
outputs:

Technical relationships for modeling pavement deterioration and vehicle
operating costs;

Procedures for applying the technical relationships for road asset
management; and,

The HDM-4 software.

It provides a powerful system for: 

       Road management 

      Programming road works 

      Estimating funding requirements 

      Budget allocations

      Predicting road network performance

      Project appraisal

      Policy impact studies 

There are four main areas of application 

      Strategic planning 

      Roadwork programming

      Project analysis

      Research and policy studies 

Strategic Analysis

Used to prepare medium to long tern planning estimates of funding needs
for road network development and maintenance. Estimates of the medium to
long term budget requirements for the entire road network together with
forecasts of pavement performance and road user effects can be obtained.
The impact of different Budget Scenarios can be estimates together with
the Asset Value of the network. 

Programme Analysis 

Used to prepare rolling work programmes in which candidate road sections
are identified and assigned maintenance or improvement options. HDM-4
calculates the economic benefits and expenditure requirements of each
option. A schedule of optimum pavement maintenance and/or road
improvement projects which can be carried out within specified budget
constraints are identified. 

Project Analysis 

Project analysis can be used to estimate the economic or engineering
viability of road investment projects by performaing life cycle analysis
of pavement performance, maintenance and/or improvement effects together
with estimates of road user costs. The main outputs include:

      Annual predictions of pavement performance

      Pavement maintenance and road improvement effects

      Road user costs and benefits 

      Estimates of environmental effects 

      Standard economic indicators; NPV,EIRR

Sensitivity Analysis allows a user to investigate the impact of
variations in key parameters on the analysis results. 

Multi-Criteria analysis (MCA) provides a means of comparing projects
using criteria that cannot easily be assigned and economic cost. For
example, environmental, social or political impacts. 

Research and Policy Studies

HDM-4 can be used to conduct a number of road sector policy studies
including: 

       Funding policies for competing needs, e.g. feeder versus main
roads 

       Impacts of road transport policy changes on energy consumption

       Impact of axle load limits 

       Pavement maintenance and rehabilitation standards

Configuration and Calibration 

Default data and calibration coefficients can be user defined for any
country or region. This allows HDM-4 to be configured to suit the
customers' local conditions and therefore can be applied throughout the
world. 

HDM-4 in Pavement Management Systems

By exchanging data with a Pavement Management System (PMS) or other
database HDM-4 can utilize existing data to perform an analysis. The
output reports can be adapted to individual requirements thereby
integrating HDM-4 into an existing road management framework. 

Please refer to the attached information sheet for more information and
course registration details.
