2.  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?

3.  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.

18. Presented at “RCUK Digital Economy All Hands event”:
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
