The New Cube Practice Guide to
Modelling Transport
Based on the textbook
‘Modelling Transport , 4th Edition’
by
Juan de Dios Ortuzar and Luis (Pilo) Willumsen
The Book
•
The book has been used since its first
edition in 1990 by transport modellers
around the world to find and select
appropriate methods to their
modelling tasks and for understanding
the theoretic base behind these
methods
•
The book includes a wealth of
examples of how to model, in terms of
approach and mathematics, the
various aspects of transport

•
Part of the Cube’s Learning Center
Comes with downloadable Cube catalog
Open to all users of Cube and to those who are evaluating the system
This guide will make it easier for modelers to put the lessons learned
in the book to practical use in models
The main purpose of this guide is to promote good modeling practice
based on established methods described and discussed in the book
This guide is also meant to encourage the modelling community to
keep up to date on modeling methods and principles; the book is an
ideal starting point
 Suggestions for the
MODELLER :
• find and study the appropriate
method in the book
• study the relevant example in the
book
• see how this example is coded in
Cube
• use the script as a base for your
model and its data
 Suggestions for the
STUDENT :
• read the relevant chapter/model
type and its modelling methods in
the book
• study the examples
• see how these example are coded
in Cube
