PROJECT BACKGROUND: Household travel surveys (HTS) are designed to provide information about daily travel patterns, including

trip purposes, time of day decisions, mode choices, trip lengths and distances, activity locations, and

routes taken. This information is typically gathered from self-reported information in a diary, with the

information retrieved via a computer-assisted telephone interview (CATI), a web-based survey, or

mailback of the completed diary. Unfortunately, it has been demonstrated that self-reporting leads to

inaccuracies in travel information. The biggest short-coming is trip underreporting. For instance, recent

work by Wolf et al., (2003), Pearson (2004) and others has shown that diary information retrieved through

CATI when compared with GPS measured travel suggests trip under-reporting ranges from 20 to 30

percent. The diary approach has also shown time inaccuracies and origin-destination location errors;

respondent fatigue often results in self-reporting human errors.
