A feasibility study of the effect of phone-based feedback of other commuters’ subjective experiences on driver intentions to change

Encouraging people to make sustainable transport choices remains a global challenge and many interventions have been attempted. This study investigated the reflection on own/others’ subjective experiences (SE) as an intervention using a smartphone application as the intervention tool. Participants were car drivers and used the app to automatically capture and reflect on their commute journeys and experiences. The experimental group were also able to reflect upon others’ experiences across car, walk and cycle modes. Others’ experiences were designed based on a previous self-report study. Results of the study showed that quantitative measures of intentions to change were not affected by the intervention but that qualitative data showed that the positive experience of the active transport modes did bring about reflection on behaviour and a potential influence on opinions and intentions which warrants further study.
