摘要：	As Global Positioning Systems (GPS) recordings become more accurate, reliable, and cost efficient, can they entirely replace travel diaries. By using GPS, the accuracy of spatial and temporal data collected on travel patterns can be greatly improved, and the duration of observation can be extended to better capture variability in travel. Respondent fatigue and corresponding errors are limited. However, to replace the travel diary method with GPS, both travel mode and trip activities/purpose have to be imputed from available data. The goal of this research was to investigate whether such imputation methods can be sufficiently developed to justify replacing travel diarydata collection methods with GPS. A secondary goal was to demonstrate that a fully representative sample of households will cooperate with GPS recording methods. This project was the first GPS-only full-scale household travel survey in the USA.
