The impact of policy measures on promoting the modal shift from road to rail

This paper aims to examine the impact of policy measures on promoting a modal shift. Based on the results put forth by previous research, we first formulate hypotheses that describe the effects between policy measures and modal shift. Using these hypotheses, we set up the research framework to complete this study, which is then tested with data (sample size 171) and AMOS 18.0. The paper contributes to the literature in the following ways: First, we verify this impact with statistical analyses through testing hypotheses based on the previous research. Second, we develop the model describing the effects between policy measures and clarify their directivity with structural equation modeling. The directivity of effects accounts for the interaction and relationship between policy measures to promote a modal shift. In this paper, we clear up the effects of policy measures better in order to promote a modal shift, which the previous research discussed conceptually.
