Does supervision in multi-day travel surveys lead to higher quality? A comparison of two independent surveys

The aim of this paper is to analyze whether the level of supervision influences quality of response and results of multi-day surveys. For that reason, we compare a multi-day survey (seven consecutive days) with children and high level of supervision in Austria (UTS) with data of the same age group out of the Mobility Survey in the Greater Stuttgart Region (MOSt). The results show that supervision during the survey process has nearly no influence on fatigue effects. Nevertheless, the quality of answers in supervised surveys is be better in terms of reporting intermodality or trip stages.
