Experience sampling system via smartphone
platform
Collection and delivery of information on subjective
travel experience.
Trials will feedback information to individuals
their own experiences
those of others
Do these interventions change behaviour?
2
Reduce travel emissions through behavioural change.
Experienced utility vs. decision utility
Does reflection on experience cause people to think
differently about the journeys
… does this promote behaviour change
Motivated by own wellbeing (optimal time-use), not
environmental issues per se.

Future Work ...
Develop a common platform for storing journey data from participants for two EPSRC
projects and two TSB projects.
• build-up a repository of sensed data (GPS trajectories, journey times, journey experience samples, user-
generated content) for travel applications
• Minimise ‘cold-start’ problem for future participatory sensing & crowd-sourcing applications
• Added-value for existing silos of sensed data
