Özet
This study represents a moving block signaling system model. In this system, different from the conventional railway systems, there are access points near the railway and moving trains communicates via them. In this way, not only railway traffic flow is increased but also waiting time for the passengers is decreased, especially in metro lines. In this work, representing a multi-carriage train, multi-degree of freedom mass-spring-damper models are used. Then, a tractive force and braking force are applied to the system as an input and location is obtained from this output. In addition, a limit movement authority is defined for control algorithm. So, trains move according to this authority. Finally, for the safe stop of trains, brake distance value is calculated. This equation is solved depending on the speed of the rear train. So, if the rear train accelerates, the distance will increase according to the square of the speed of the rear train. Besides, depending on the speed of the rear train and travel time, a safety margin distance is obtained. The proposed technic is simulated by using Matlab-Simulink (TM) and the results including train models, speed profiles, locations, accelerations etc. are shown in Figures.
