Scaling perceptions of reliability of urban travel modes using indscal and factor analysis methods

Abstract

In several attitudinal investigation, travel modes' reliability was found to be the most important characteristic of the transportation system. This research is concerned with individual subjective evaluation of different reliability attributes. Two scaling techniques—Indscal factors analysis—were used to investigate travel modes' reliability; these techniques aided in the identification performance measures of reliability. The scaling techniques were also evaluated and compared for thier usefulness and the reliability performance measures were validated using a preference model.
