  1. 1. OneBusAway: Results from Providing Real-Time Arrival Information for Public Transit An evaluation of a paper from CHI 2010
  2. 2. The service • OneBusAway provides real-time arrival data for commuters in Seattle • Initiated in 2008 • System evaluated in August 2009 via an online survey
  3. 3. How OneBusAway (OBA) works • OBA is a tool that provides bus information • Delivered via various interfaces • mainly mobile technology • text • iPhone • web • phone number
  4. 4. Contribution • People are generally more satisfied with using buses as a result of OBA • Service has reduced impact of ‘slack time’ • Reduction of costs associated with hardware to provide this information at physical locations
  5. 5. Survey • Web based survey via user questionnaires and free-form comments • Anonymous • Incentive: winning $25 • Participants recruited via: • OBA site • Social networking sites • Blogs
  6. 6. Survey focus • Impact the OBA service has made on commuters’ use of buses • Does not look at the contribution of the functionality of OBA
  7. 7. Survey findings • Users feel more in control of their time • Better perception of safety • Increased use of public transport • Increased levels of fitness • Generally: usability of public transport can be enhanced by providing good traveller information systems
  8. 8. Assessment of evaluation methods used • Good: • Free-for comments gather qualitative information • Same questions asked in different guise to check response validity
  9. 9. Improvements to the evaluation of OBA • Focus of survey • Sample population skewed/not guaranteed representative • Control group • Direct measurements of behaviour
  10. 10. Suggestions • 25% of respondents had data reliability issues and usability complaints • Include: • Ease of learning • Effectiveness • Efficiency • Does it meet the needs of the user?
  11. 11. Final suggesitons • Engage Usability testing to provide quantifiable data on how the tool is performing (Mayhew, D. J.1999) • Field studies
  12. 12. References • Mayhew, D. J. (1999) The Usability Engineering Lifecycle. Morgan Kaufmann, San Francisco. • Sharp, H., Rogers,Y., Preece, J. (2007) Interaction Design: beyond human- computer interaction 2nd. ed
