摘要：	This paper reports on an examination of the issue of whether the Nationwide Personal Transportation Survey (NPTS) and the American Travel Survey (ATS) data can be combined. The question was addressed by first examining the comparability of the data sources. Comparability between the two surveys is established from the viewpoint of whether the resulting summary travel statistics categorized by trip purpose and travel mode are significantly different from each other. Since round-trips going to places at least 100 mi away from home are a common element in both surveys, this analysis is limited to those trips. If the statistics for these long trips are not comparable, then the analysis identifies reasons contributing to the differences. A simulation was undertaken to determine how different data collection time periods, which the two surveys used, impact final survey results. Finally, recommendations are offered to increase the data comparability between the next NPTS and ATS in the year 2000.
