교통신호제어기 실시간 감시를 위한 시뮬레이션 모델 구축 = Simulation Model Construction for Real-Time Monitoring of Traffic Signal Controller

다국어 초록 (Multilingual Abstract)

This paper proposed the real-time monitoring methodology of a traffic signal controller. The proposed methodology is based on the simulation technology, and it is necessary to construct a simulation model imitating the behavior of a traffic signal controller. By executing the simulation model, we can obtain the ‘nominal system trajectory’ of the traffic signal controller. On the other hand, an IoT(Internet of Things)-based monitoring device is implemented in a traffic signal controller. Through the monitoring device, it is possible to obtain the ‘actual system trajectory’. By comparing the nominal system trajectory and the actual system trajectory, we can estimate the degree of deterioration of a traffic signal controller.
