About the book : Modelling Transport 4th edition
This system of Cube modelling tutorials is based on Modelling Transport 4th Edition (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. This guide provides a set of applications showing the examples of the book coded up in Cube scripts, grouped according to the book's chapters. 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 ________________________________________________________ About the MT Cube Guide : Version 1.0 September 2011 Authors : Citilabs professionals © Citilabs 2011 About the 'book' : Modelling Transport 4th Edition, © 2011 John Wiley & Sons, Ltd Authors : Juan de Dios Ortuzar Luis G.
