Value of travel time savings for shopping trips in Switzerland
نویسندگان
چکیده
The Swiss study of the value of travel time savings (VTTS), conducted by König, Axhausen und Abay (2004) reported unexpectedly high values for shopping trips from early experimental stated preference experiments, which were finally not included in the main study. Therefore a study focusing only shopping travel was conducted to see, if these results could be replicated. This study estimates VTTS for shopping trips which are significantly higher than those in other studies. Values between 53 and 110 CHF/h are observed depending on the preferred supermarket. The effect of the preference for shopping in low price supermarkets on the VTTS is much stronger than income or the travel distance. In contradiction to the findings of the study by Koenig et al. the value of travel time savings decreases with longer distances. Further work which considers the travel and shopping expenditures separately besides shopping location preferences could probably give an even better understanding of VTTS of shopping travel.
