Spreading peak demand for urban rail transit through uddifferential fare policy : a review of empirical evidence

摘要

More evenly spread demand for public transport throughout a day can reduce transit service provider‟s total asset and labour costs. A plausible peak spreading strategy is to increase peak fare and/or to reduce off-peak fare. This paper reviews relevant empirical studies for urban rail systems, as rail transit plays a key role in Australian urban passenger transport and experiences severe peak loading variability. The literature is categorised into four groups: ududa) passenger opinions on willingness to change time for travel, ududb) valuations of displacement time using stated preference technique, ududc) simulations of peak spreading based on trip scheduling models, and:ududd) real-world cases of peak spreading using differential fare. ududPolicy prescription is advised to take into account impacts of traveller‟s time flexibility and joint effects of mode shifting and peak spreading. Although focusing on urban rail, arguments in this paper are relevant to public transport in general with values to researchers and practitioners.
