The Satisfaction with Travel Scale (STS) has recently been developed to measure people’s satisfaction with travel. It supposedly consists of two affective and one cognitive dimension. As there have only been a few tests of its reliability and structure to date, this paper reports new tests using data on leisure trips from Ghent (Belgium). Differences in the reliability and structure of the STS by transport mode - car, public transport, bicycling and walking - are also considered. Overall, the results suggest that the specification of a single underlying dimension for affect rather than two offers a superior fit to the Ghent data, both for all modes combined and for car use and cycling separately. For public transport and walking a three-dimensional structure is more appropriate although individuals items do not load on the two affective dimensions as expected. Differences between previous studies and ours are partly caused by differences in how two of the scale’s items - alert/tired and confident/worried - are correlated with the other items. Future studies using the STS may want to adapt the structure of STS by omitting some items or replacing them with alternatives as this may reduce respondent burden and increase internal consistency of the STS.
