Empirical Analysis on Driver's Perception and Evaluation Structure toward the Quality of Service for Traffic Conditions with Considering the Influence of Order Effect

Abstract

This study examined the existence of order effect on the driver's perception in the point-basis evaluation of the quality of traffic service. It is found that there exists order effect in the point-basis evaluation by using the controlled evaluation data and the driver's utility data, and the precision of the model is improved by considering order effect. Also the model which estimates a section-based evaluation from an average and a maximum of a set of point-basis evaluation in a certain section is developed With these results, it is shown that the point-basis evaluation of the quality of traffic service can be estimated from a micro-scopic traffic conditions.
