ABSTRACT
Studies on social networks and social influence have found ample application in different disciplines. The recently gained interest in these concepts in transportation research triggers the question whether social influence plays an equally important role in explaining transport-related choices and decision-making processes. In this chapter, we summarise three of our studies that we completed over the last couple of years to address the question whether social influence is a key concept influencing the behaviour of interest: job application decisions, the intention to buy an electric car and the decision to join a car-sharing organisation. Although different representations of social influence and different analyses were adopted in the three studies, results of all three studies suggest that the relative importance of social influence variables is low compared to the importance of the attributes of the choice alternatives in general and particularly compared to costs considerations.
