The SUPERHUB project (SUstainable and PERsuasive Human Users moBility in future cities) promotes the creation of a new urban mobility services ecosystem to facilitate the take-up of environmentally sustainable behaviours. It will design and test an open platform able to combine in real time all mobility offers from the relevant stakeholders together with a set of enabling mobility services able to address users' mobility needs and to foster behavioural change. This paper explores how SUPERHUB plans to integrate behaviour change theories.
