Transport models include the mathematical and logical abstractions of real-world systems. It is common to describe the traffic system as a non-cooperative agents game, assuming travellers’ behaviour is selfish by nature (focus on optimizing outcomes for themselves, without considering much others’ benefits). In this paper, some basic concepts of pro-social behaviour are illustrated. Adding to the individual user’s utility function a component to represent social value, the user equilibrium is extended to a social equilibrium. The sensitivity of the social equilibrium to social values is investigated. Also introduced here is a dynamic travel-choice model of travel behaviour which considers social value orientation. The potential for incorporating social aspects in the development of transport modelling is demonstrated by a numeric example.
