A two-stage RP/SP survey to estimate the value of travel time in Switzerland: Short- versus long-term choice behavior

Studies obtaining the value of travel time (VTT) typically have used data about short-term decisions such as mode/route choice. We present new results of long-term VTT using stated preference (SP) data on residential and workplace location choice and compare them with short-term (ST) values for the same respondents. In the long-term (LT) the VTT tend to be higher for car/motorbike (most pronounced for work trips by more than factor two) and public transportation, while for bike they tend to be lower. We conclude that collecting LT data may be more problematic, since it is based on stronger assumptions about the choice context, the choice situations are harder to process by the respondents, many relevant attributes cannot be included due to the otherwise too high complexity of the SP task and the travel related attributes need to be weighted according to the trip frequencies to obtain the relevant VTT metric
