“…Among them, six papers only employed spatial proximity for mode detection (Doyle et al, 2011;Holleczek et al, 2015;Horn and Kern, 2015;Phithakkitnukoon et al, 2017;Poonawala et al, 2016;Wu et al, 2013), which were mostly for intercity trips or trips between metro/MRT/train stations. The other 10 papers additionally considered other trip-related attributes, such as trip speed (Danafar et al, 2017;Larijani et al, 2015;Smoreda et al, 2013;Yamada et al, 2016), trip distance (Asgari, 2016;Qu et al, 2015), trip duration (García et al, 2016;Li et al, 2017;Schlaich et al, 2010), and temporal overlap with timetables of public transport (Horn et al, 2017;Yamada et al, 2016).…”
