Smartphones are increasingly used for collecting data on travel behaviour. Among others, this approach can support the development of a holistic view of Value of Travel Time (VTT) beyond the time and cost savings dimensions. Smartphones enable collecting data on the travel experience itself. This subjective dimension is still relatively under-researched. Knowledge gathered in this area can support reconsidering the traditional negative connotation (i.e. disutility) of travel time. While challenging to be captured and described, data on the subjective travel experience would allow better understanding to what extent people make worthwhile use of their time while travelling. Multiple challenges, not only technical ones, need to be addressed to collecting high-quality data on the subjective travel experience, which depends on the level of user engagement with the app. The adoption of a Quantified Self (QS) approach to implement a “smart mobility coach” is introduced as a promising mechanism for addressing these issues, based on the principle that the collected data should provide value to the user: specifically, the smart mobility coach should allow users discovering what value of travel time mean for them in relation to their expected quality and characteristics of travel experience. Apart from being useful to end users, knowledge on the subjective value of the travel experience would also allow designing and implementing transport and mobility solutions from the travellers’ perspective.
