- Confirmatory factor analyses are used to examine the psychometric properties of the satisfaction with travel scale (STS), including tests of measurement invariance across urban areas and travel modes (car, public transport and slow modes). The data set consists of questionnaire responses from random samples of residents of Sweden's three largest urban areas. A theoretically supported, one-factor second-order measurement model with three separate constructs received empirical support in analyses of satisfaction with daily travel in general, satisfaction with the commute to work, and satisfaction with the commute from work in the different urban areas and with different travel modes. On the three first-order factors, high loadings were as expected obtained on scales involving cognitive evaluations (e.g. "low vs. high standard") and affective evaluations with respect to positive deactivation (e.g. "relaxed vs. stressed") and positive activation (e.g. "alert vs. tired"). Satisfaction with daily travel in general differed significantly in the largest urban area from the medium-large urban area and the smallest urban area. The results also revealed that commuters travelling by bicycle or on foot are more satisfied with their work commute than people using other travel modes.

- In general trips frequently entail several stages varying in mode, duration, and other factors. In some way travelers aggregate their satisfaction with the stages to satisfaction with the whole trip. In this paper we address the question of how this aggregation is made. We use data from a Swedish survey measuring satisfaction with commutes to and from work and with the stages of the commutes. We test several aggregation rules for their goodness of fit to the observations. Our results show that a normatively correct averaging rule that takes into account the relative durations of the stages out-perform heuristic aggregation rules such as the peak-end, summation, and equal-weight averaging rules. We note that this does not exclude that the heuristic aggregation rules apply to other trips than repetitive commute trips.
