Juan de Dios Ortúzar Salas (born 24 January 1949) is a Chilean industrial engineer and Emeritus Professor at the Pontifical Catholic University of Chile (PUC).[1] Regarded as a pioneer of discrete-choice modelling, he developed methods for estimating travellers’ willingness to pay for safer, cleaner and quicker journeys.[2]

Early life and education

Ortúzar earned a BSc in mathematics and a civil-engineering degree at PUC.[3] He moved to the United Kingdom in 1973 to study at the University of Leeds, receiving an MSc in transport planning in 1974 and a PhD in 1980 for research on discrete choice modelling.[2]

Academic career

Ortúzar joined PUC's Department of Transport Engineering on returning to Chile, became full professor in 1986 and was named Professor Emeritus in 2016.[3] He directed the first origin-destination survey of Greater Santiago (1991) and launched the city's continuous household travel survey in 2001.[4]

He helped to found the Institute for Complex Engineering Systems (2007); the BRT⁺ Centre of Excellence for Bus Rapid Transit (2010);[5] and the Centre for Sustainable Urban Development (CEDEUS) in 2012.[6]

Research and influence

Combining stated-preference and revealed-preference data, Ortúzar's work quantifies how travellers trade time, money, safety and environmental quality. The valuation techniques devised with his group have been applied in appraisal studies and legal cases in Australia, Colombia, Germany, Norway and Spain.[2] His interdisciplinary projects range from social-housing location and urban road pricing to preferences for Chilean wine.

Publications

Ortúzar has authored or co-authored more than 200 refereed papers. His textbook Modelling Transport, written with Luis G. Willumsen, is a standard reference in the field and reached its fifth edition in 2024.[7]

Honours
