Due to the comparatively low frequency of long-distance and overnight travel, it can be challenging to measure using traditional travel surveys. In response to this dearth of data, several recent surveys have included self-reported frequency questions. However, the value and accuracy of these questions is unclear. This study leverages data from 628 panel members who completed a year-long, online survey in 2013–2014 by comparing their one-time self-assessment of typical overnight trip frequency to those reported in 12 subsequent monthly surveys. The self-assessed frequency of overnight tours, airplane tours and tours to non-North American destinations are consistent for only 68% and 70% of respondents for work and personal tours respectively. For most tour types, consistency is highest for low frequency (never and |
