Determination of the valuation of a transfer in a multimodal public transport trip from a passenger point of view.
Improvement of chain mobility is considered a major issue in public transport use. Transfers within a public transport trip are the least appreciated part of the trip. This research determines how the experienced transfer disutility of a transfer between BTM and train. The influence of travel time, transfer time, headway, costs and station facilities on such a transfer are quantified. Furthermore, the importance of these attributes are differentiated for personal and trip characteristics. The research is carried out within a Dutch context of public transport.
A web-based stated preference (SP) experiment was carried out using discrete choice modelling. The choice situations were described by the attributes BTM trip time, transfer time, in-train time, headway of the connecting mode, costs and station facilities. The experiment included choice situations between two BTM-train alternatives and choice situations between a BTM-train alternative and a train-train alternative. A general mixed logit model is estimated expressing the disutility of the different attributes on the total transfer disutility. Furthermore, submodels are estimated, with different selections of respondents. Submodels are estimated on trip motive, travel frequency, access/egress mode and trip stage (access or egress transfer).
Based on the comparison of a BTM-train transfer with a train-train transfer, the BTM-train transfer disutility is estimated. A transfer between BTM and train with a transfer time of 8 minutes and a headway of the connecting mode of 15 minutes results in a transfer disutility of 29 minutes generalized travel time (GTT). The transfer disutility turns out to be highly dependent on transfer time and the headway of the connecting mode. In general, the most optimal transfer time is found to be 8 minutes, but differences are found between respondents and stations. Insights into the preferences of different groups of travelers are provided which can be used by public transport service providers to meet the travelers’ wishes in a transfer and thereby decrease the transfer disutility.
