Intersection Simulation System Based on Traffic Flow Control Framework

This paper proposes the Intersection Simulation System which can dynamically manage the real-time traffic flow for each section from the intersections by referring to the traffic information database. This system consists of the hierarchical 3 layers. The lower layer is the physical layer where the traffic information is acquired on an actual road. The middle layer, which is the core of this system, lays the Traffic Flow Control Framework designed by extending the distributed object group framework that we developed before. This layer supports the grouping of intersection, the collection of real-time traffic flow information, and the remote monitoring and control by using the traffic information of the lower layer. In upper layer, the intersection simulator applications controlling the traffic flow by grouping the intersections exist. The key idea of our study is the grouping concept that can manage the physical world in the defined logical space. The intersection simulation system considers each intersection on road as an application group, and can apply the control models of traffic flow by the current traffic status, dynamically. For constructing this system, we defined the system architecture and the interaction of components on the traffic flow control framework, and designed the application simulator and the user interface for monitoring and controlling of traffic flow.
