EFFECT OF CLUSTER SAMPLING ON THE DATA PRECISION OF PERSON TRIP SURVEY

Person trip survey is a fundamental data source for transportation studies but its characteristics in data precision are rather vague. The author points out that the survey makes up the sample by cluster sampling and that the effect of the sampling method on data precision cannot be ignored. Hitherto, the standard error of estimates obtained by the survey has been estimated on the assumption that the sample from the survey is random. This assumption was examined by means of a re-sampling experiment and shown to be incorrect. Then, a method to estimate the standard error was developed, taking the effect of cluster sampling into consideration. Finally, the advantages of using a household and a person as a sampling unit were compared from the viewpoints of data precision and survey cost. (Author abstract)
