Abstract :
[en] This paper investigates the transition of the Flemish travel survey (OVG) from a household-based travel survey to a person-based travel survey. The paper examines the design features of the different OVGs, with particular attention to the resulting response rates. In addition to the sample unit, the contact and survey procedure has switched from telephone/postal to face-to-face. The most striking effect of the changed methodology is the spectacular increase in the response rates: overall response rates of the most recent OVGs were more than double that of the previous OVGs, resulting in overall response rates of 75%. In addition, the likelihood that some questionnaires were missing (e.g. diaries were retrieved, but household questionnaires were not) decreased from 7% to 3%. Furthermore, the paper shows that a person-based travel survey still can be used for travel demand modeling frameworks that incorporate (some) household interactions. Notwithstanding, some issues have been raised, such as the decreased comparability of travel figures due to the changes in the survey design. In conclusion, the inclusion of a “with whom” dimension in the trip diary is recommended, and it is advocated that policy makers should clearly outline the primary objectives for the OVG for the coming years.
