Abstract

RESULTS of a research project on underreporting of trips in telephone interview household travel surveys arising from memory lapses and the use of proxies are presented. On the basis of a survey of approximately 61,000 households in the greater Toronto area, the effects of these two factors on reported automobile mobility characteristics were analyzed with respect to trip characteristics and to socioeconomic characteristics of households and individual trip makers. The analysis showed trip underreporting to be the rule for short discretionary trips and trips made during off-peak periods. Using these insights, correction procedures were developed to minimize the effects of trip underreporting.
