DESCRIPTION:Prof. Elisabetta Cherchi\, Associate Professor\, DTU\, Lyngby\
 , Denmark\nAccording to Crutchfield (1955) individuals consciously or unco
 nsciously tend to "yield to group pressures" and consequently to act in ag
 reement to the majority position. Social conformity has been extensively s
 tudied in psychology with also several applications to transport problems.
  Field experiments are typically used to evaluate the impact of social inf
 luence on self-reported changes toward environmentally sustainable transpo
 rt behaviours. In this research\, we discuss various aspects of social con
 formity and present a stated preference experiment set up to measure their
  effect on individual preferences. The choice of electric cars is used as 
 an illustrative example. In particular\, we explicitly measure how individ
 uals' preference change before and after they have received social informa
 tion on other's experience about driving range\, about the need to adapt t
 he activity schedule and about the benefit of parking policies. The effect
  of descriptive norm and other-signalling concern are also measured as par
 t of the stated preference experiment\, while injunctive norms are measure
 d with typical statements on a 7-point Likert scale. Results from the esti
 mation of mixed logit model and hybrid choice models\, clearly confirms th
 at the experience (especially negative) of other people has a powerful eff
 ect on individual preferences for range and parking policies. Results also
  confirm that individuals' behaviour is affected by the image they want ot
 her people to have of them\, making them "more honest" in their answers.\n
 Bio : Elisabetta Cherchi is Associate Professor at the Department of Trans
 port\, Technical University of Denmark\, where she is also Deputy Head of 
 the Ph.D. school in Transport. She is Area Editor of Transportation\, and 
 member of the editorial board of Transportation Research part B\, Journal 
 of Choice Modelling and Transport Policy. She is also Secretary and Treasu
 rer of the International Association for Travel Behaviour Research (IATBR)
 . Her research interest is in data collection\, in the behavioural backgro
 und of demand modelling and in how to use and expand it to study emerging 
 problems such as understanding what drives sustainable transport behaviour
  and how it can be promoted.
