Title
Quantified Traveler: Travel Feedback Meets the Cloud to Change Behavior
Abstract
We describe the design and evaluation of a system named Quantified Traveler (QT). QT is a computational travel feedback system. Travel feedback is an established programmatic method whereby travelers record travel in diaries, and meet with a counselor who guides the user to alternate mode or trip decisions that are more sustainable or otherwise beneficial to society, while still meeting the subject's mobility needs. QT is a computation surrogate for the counselor. Since counselor costs can limit the size of travel feedback programs, a system such as QT at the low costs of cloud computing could dramatically increase scale, and thereby sustainable travel. QT uses an application (app) on the phone to collect travel data, a server in the cloud to process it into travel diaries, and then a personalized carbon, exercise, time, and cost footprint. The subject is able to see all of this information on the Web. We evaluate the system with 135 subjects to learn whether subjects will let us use their personal phones and data plans to build travel diaries, whether they actually use the website to look at their travel information, whether the design creates pro-environmental shifts in psychological variables measured by entry and exit surveys, and finally whether the revealed travel behavior records reduced driving. Before-and-after statistical analysis and the results from a structural equation model suggest that the results are a qualified success.
