Author: Juan de Dios Ortuzar, Luis G. Willumsen | Size: 3.64 MB | Format: PDF | Publisher: Wiley | Year: 2011 | pages: 606 | ISBN: 0470760397
Providing unrivalled depth and breadth of coverage, each topic is approached as a modelling exercise with discussion of the roles of theory, data, model specification, estimation, validation and application. The authors present the state of the art and its practical application in a pedagogic manner, easily understandable to both students and practitioners.
This book try to present the most important (in authors views) transport modelling techniques in a form accessible to students and practitioners alike, and attempt this giving particular emphasis to key topics in contemporary modelling and planning:
• the practical importance of theoretical consistency in transport modelling;
• the issues of data and specification errors inmodelling, their relative importance andmethods to handle them;
• the key role played by the decision-making context in the choice of the most appropriate modelling tool;
• how uncertainty and risk influence the choice of the most appropriate modelling tool;
• the advantages of variable resolution modelling; a simplified background model coupled with a much more detailed one addressing the decision questions in hand;
• the need for a monitoring function relying on regular data collection and updating of forecasts and models so that courses of action can be adapted to a changing environment.
Enhancements include two entirely new chapters on modelling for private sector projects and on activity-based modelling; a new section on dynamic assignment and micro-simulation; and sizeable updates to sections on disaggregate modelling and stated preference design and analysis. It also tackles topical issues such as valuation of externalities and the role of GPS in travel time surveys.
