The New Cube Practice Guide to Modelling Transport

Based on the textbook‘Modelling Transport , 4th Edition’

byJuan 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

The Cube Guide

• 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
