UNDERSTANDING COMMUTERS' ATTITUDES, UNCERTAINTIES, AND DECISION-MAKING AND THEIR IMPLICATIONS FOR ROUTE CHOICE

This study describes a second computer-aided telephone interview (CATI) survey designed to gain in-depth understanding of commuters' perceptions and decision processes, to study the effect of travel time uncertainty on route choice, and to study carpool characteristics. The survey was undertaken in May 1993, targeting the same sample of commuters interviewed in May/June 1992. An attrition model illustrated that income and gender are among the significant socio- economic variables that increase the probability of a respondent participating in the second wave of the survey.
