A Structural Equation Model of Elementary School Services Based on Latent Factors

School travelling is relatively undeveloped in transport research. More researchers hast identified the socio-economic and environmental characteristics on choice of school travel mode. The main purpose of this study is to determine the role of Psychological factors (latent variables) on school service mode. This study uses a dataset gathered in January 2015 in Mashhad, from 28 elementary schools (including public and private, boys and girls schools) and 820 questionnaires are filled out by the parents. A Structural equation model (SEM) is built by 625 records in AMOS software. SEM results shows that parents who are strongly worried about pupils while walking are more likely to choose school service for school trips. Parents who are highly worried about using school service had the negative effect on choosing school service. The Results suggest that perceived travel time, child birth order, risk perception, perception of environment, children’s competence and cultural factors are all statistically significant in children school service mode choice.
