ABSTRACT
As travel patterns become more complex, many public transport users have to make transfers between different modes to complete their daily journeys (Hernandez et al. 2015). It is essential therefore to make interchanges attractive places to transfer in order to achieve or maintain a high level of public transport use. In this respect, measures oriented to improve public transport service quality are required, such as reducing the inconvenience of transfer and providing a seamless travel experience. In this context, the EU Green Paper on urban mobility (European Commission 2007) emphasised that sustainable mobility aims to address three challenges: reducing congestion; improving the quality of public transportation services to achieve a modal shift from private car to public transport; and promoting the soft modes of walking and cycling. Moreover, total travel time directly influences trip choices. Good connectivity at public transport stops and stations is therefore critical to the effectiveness of the overall transportation network (Iseki and Taylor 2010).
