This paper describes the overview of ETC system in Japan, and focuses on the issue of traffic jams, which occurs around toll plaza of expressway even after the introduction of ETC system. For a solution to this issue, this study proposes a process simulation-based approach to study and evaluate the layout design of toll plaza. The paper presents process simulation model which has been implemented in this study, and evaluates the quality of the model. Then, several layout design examples were proposed and studied based on the model, and the validity of our approach will be discussed.
