ADJUSTING HOUSEHOLD SURVEY EXPANSION FACTORS

Various developments in survey expansion techniques have been applied recently to household travel surveys in major metropolitan areas in the United States. Nonresponse bias has been evident, though, so to counteract this problem, adjustments are required in the process of expanding a survey sample to represent the regional population. This paper, which appears in a compendium of conference papers, presents a three-step procedure for establishing factors (weights) to expand the data from the 1991 Boston Regional Household-Based Travel Survey. The first step is to develop a set of basic expansion factors. The second step is to adjust the expanded total households from the survey to match the Census estimates of total households at the land use zone level. The final step is to integrate trips made by members of sample households who did not return their travel diaries.
