“…Indeed, a search in the literature using keyword combinations of mobile phone data, mobility, and travel behavior resulted in more than 1000 articles published in journals across different disciplines (Ahas et al, 2010a; Becker et al, 2013; Calabrese et al, 2013; Candia et al, 2008; Chen et al, 2014, 2016; Gao et al, 2013; Song et al, 2010b; Wang et al, 2014). These articles cover a wide range of topics including, for example, estimating mobility patterns (Csáji et al, 2013; González et al, 2008; Song et al, 2010a), inferring OD matrix (Calabrese et al, 2011b; Iqbal et al, 2014), finding anchor locations (Dong et al, 2015; Isaacman et al, 2011), inferring activity types (Jiang et al, 2017; Widhalm et al, 2015) and travel modes (Qu et al, 2015; Wang et al, 2010). …”
