The Overnight Travel Survey

Map of Study Participants

Background: The Overernight Travel Survey is being conducted monthly online between February 2013 and January 2014. The overall goal was to measure planned and executed overnight trips for all purposes by individuals over age 24 years over a 12-month period. While each monthly survey focuses on planned and completed overnight trips, the introductory survey data, which is already being analyzed asked about participation in long-distance trips of all types. Given the known challenges of panel surveys, diverse types of recruiting were deliberately designed for this study. Participants from universities and transportation agencies (who were expected to be more vested in the study) were supplemented with general public participants through email, listservs, e-newsletters and Facebook announcements. The sample includes 1220 individuals who volunteered to participate in the study by taking the survey monthly for a full year.

The recruiting strategy created a less representative sample that would be desirable for forecasting but was deemed necessary to ensure retention in this first longitudinal study of overnight travel. While some demographics are representative (62% female, half of the sample is between 40 and 59 years old and 36% is under 40 years old), others are not (89% of the participants had an associates, bachelor?s or graduate degree, 15% of the sample had a household income of $150,000 or more per year with only 16% below $50,000 per year). Seventy-nine percent of the sample works 5 or more days outside of the home (a biased but not unexpected situation due to the reliance on work places for recruiting)
