Modeling Pedestrian Degree of Satisfaction Based on Structure Equation Model

Pedestrian's degree of satisfaction with non-signalized intersection' safety and other level of service for pedestrian crossing is a comprehensive index which it is difficult to obtain when evaluating the design quality or operation level of non-signalized intersections. However, the degree of satisfaction is a latent factor that can be estimated from observed factors, such as: design characteristics of non-signalized intersections, traffic flow characteristics, or behavior and qualitative environment factors, using structural equation model. In this paper, five non-signalized intersections are chosen to sample data for building the proposed model. From the score of degree of satisfaction and their coefficients' values, the size of intersection, the traffic volume, and intersection supervise measures and pedestrian delay are the predominant factors which affect the satisfaction of pedestrian.
