A Moment of Time: Reliability in Route Choice Using Stated Preference

Understanding how reliability is valued is important because it provides insight to how aims of policies that aspire to provide better transport options can be more fully integrated with user expectations. Better reliability is a desired outcome of transportation policies as it reduces scheduling costs. This study uses a stated preference survey to collect route preference data, where each route is described by the travel time experience on it. Because travel time decisions are made from momentary recollections of past experience, the paradigm adopted in this study is that the mode travel time rather than the mean is the important basis for travel time decisions. We then explore three alternate measures of reliability and use them to estimate route choice models
