Abstract
This paper provides further insight into the usefulness of smartphones and dedicated GPS devices for collecting current travel survey data. GPS and accelerometer time series for 33 European research project PEACOX study participants are available for analysis; these were tracked simultaneously with smartphones and dedicated devices for 8 weeks. Meaningful diaries can be extracted from both data sources. However, if high resolution data is needed, results suggest that dedicated GPS devices are still relevant; they have no battery issues, meaning that more data is recorded and that data quality is more stable.
