Mobile phone positioning data sets contain spatio-temporal positions of millions of mobile phone users. While their application in recent human behavior studies has seen great success, it remains to be explored by the travel behavior research community. In this study, the authors discuss the potential of mobile phone positioning data as an alternative data source for travel behavior studies. The authors are particularly interested in their potential for analyses in travel behavior dynamics. Analyses in travel behavior dynamics rely on multi-day travel data. Multi-day travel diary and Global Positioning System (GPS) tracking are two primary approaches for multi-day travel data collection. Yet, both approaches are limited in several aspects. The authors discuss the relative advantages of mobile positioning over travel diary/GPS tracking as an alternative data collection technique. As an example, a real-world mobile phone positioning data set is applied to examine the variability in individuals’ activity location choices. Results demonstrate the ability of mobile phone positioning data in capturing temporal dynamics in individuals’ spatial behaviors. The authors conclude that mobile phone positioning data are a promising data source for travel behavior study. There are, however, caveats. The authors discuss potential issues with this type of data as well as their implications when used for travel behavior studies. In addition, the authors review recent studies producing novel insights into human mobility with mobile phone positioning data from other disciplines in the hope that more travel behavior researchers will join this effort.
