Analysis of Driver's Satisfaction of Basic Expressway Segments and Satisfaction Rating Model

Abstract

 The objective of this study is to analyze the relationship between traffic conditions and driver's satisfaction with level of services (LOS) for basic expressway segments.
 Driver's perception and satisfaction about the traffic conditions has large difference among individuals, however, the aggregate satisfaction tends to constant. Then, by using the covariance structure analysis, causal relationships between drivers' satisfaction and both traffic indices and perceptions of traffic condition. Finally, for each number of lanes, a satisfaction rating model with traffic indices as independent variables is proposed.
