| Summary: | The Highway Development and Management
Model (HDM-4) is a software system for evaluating options
for investing in road transport infrastructure. Worldwide,
the HDM-4 model is most commonly used as a basis for
feasibility studies, in which a road project is evaluated in
terms of its economic viability. A more comprehensive type
of evaluation based on HDM-4 is a network evaluation, which
assesses an entire road network to help decision makers in
their strategic planning of road investments and/or the
definition of a rational road works program, with or without
budget constraints. A network economic evaluation is the
most challenging use of the model, but the effort is well
justified given the potential savings to be achieved on
transport costs by comparing various project alternatives
and performing an optimization under budget constraints.
This technical note presents the author's experience
applying HDM-4 and its predecessor, the Highway Design and
Maintenance Standards Model (HDM-III), to road network
strategic planning evaluations in developing countries, with
the objective of providing recommendations and tools to the
readers who are involved in strategic planning activities.
The purpose of the evaluations, the methodology itself, the
input requirements, the challenges, and the presentation of
results to decision makers are each reviewed in turn. |
