Passively generated mobile phone data is emerging as a new data source for research in human mobility patterns. Information on people's trajectories is not directly available from such data; they must be inferred. Many questions remain in terms how well we can capture human mobility patterns from such data. Only one study has compared the results from a mobile phone dataset to those from the National Household Travel Survey (NHTS), though the comparison is on two different populations and samples. This study constitutes one of the first, if not the first, study that systematically validates the results from a mobile phone dataset against the ground truth.
