We introduce the simplest discrete choice models (multinomial logit and nested logit) and show, first, how can they be applied to substitute the demand model components of the classic 4-step transport model (i.e. trip generation, trip distribution and mode split). We then go on to show a variety of other applications of the approach (with the aid of stated choice data), to value intangibles, such as the value of various transport externalities (i.e. environmental pollution and noise), the value of safety when walking through a potentially dangerous neighbourhood, and the patrimonial value of heritage buildings. We emphasize the roles of good data and an adequate experimental design in these tasks.
Emeritus Professor, School of Engineering, Pontificia Universidad Católica de Chile. Recipient of the Life Achievement Award (International Association for Travel Behaviour Research) in 2012 and the Humboldt Research Award (Alexander von Humboldt Foundation) in 2010. He pioneered the development of discrete choice modelling techniques and their application to determine willingness-to-pay for reducing externalities (accidents, noise and pollution). With his research team, he has developed methodologies used in Australia, Colombia, Germany, Norway and Spain.
He has published over 170 papers in archival journals and book chapters. Co-author of Modelling Transport (Wiley, 2011), a book published by Wiley reflecting the state-of-practice in this discipline. Co Editor in Chief of Transportation Research A and member of the editorial board of another nine international journals.
He directed the design and implementation work for the largest metropolitan origin-destination surveys in Chile, such as those for Santiago in 1991 (33,000 households), the Santiago on-going survey that started in 2001-2002 with 15,000 households and interviewed another 5,000 households/year between 2004 and 2007, and the Bogotá 2011 mobility survey where more than 15,000 households were interviewed.
