Title: Uncovering the Influence of Commuters' Perception on the Reliability Ratio
Accession Number: 01476085
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: The dominant method for measuring values of travel time savings and values of travel time reliability is discrete choice modeling. Generally, the data sources for these models are stated choice experiments and revealed preference observations. There are few studies using revealed preference data. These studies have only used travel times measured by devices such as loop detectors, and thus the perception error of travelers has been largely ignored. In this study, the influence of commuters' perception error is investigated on data collected of commuters recruited from previous research. The subjects' self-reported travel times from surveys, and the subjects' travel times measured by global positioning system (GPS) devices were collected. The results indicate that the subjects reliability ratio is greater than 1 in the models with self-reported travel times. In contrast, subjects reliability ratio is smaller than 1 in the models with travel times as measured by GPS devices.
