An initial entry survey was used to collect baseline and demographic data, a daily survey was used to monitor day-to-day experiences, and an exit survey was used to evaluate overall impressions at the conclusion of the field test. A total of 2,215 participants completed an initial entry survey and 1,934 participants provided feedback during and after field testing.
