Trip validation interfaces of smartphone-based travel survey solutions put to test: a comparative usability study

Solutions for smartphone-based travel surveys are currently mushrooming, yet systematic and side-by-side comparisons of different technologies are still sparse. We propose a contribution evaluating usability aspects of post-processing automatically generated trip data for validation purposes. We present a concept measuring usability performance in terms of task completion time, errors and success rate as well as subjective perception of usability of trip validation interfaces. We apply this concept to a comparative usability study putting to test three different solutions for smartphone-based travel surveys. Our approach can serve as a template for evaluating other solutions, and provides indirect hints about trip reconstruction quality.
