An Analysis of ATS(Automatic Train Supervision) Functions in the Train Control System using Use Case

As a train control system becomes a large scale and complex, it is necessary to control rigorously the system requirements specification of the train control system at the early phase. This paper describes Use Cases and activity diagrams of ATS functions requirements in the train control system. Basic functions of the train control system refers to IEC 62290-land are suggested. And the basic functions includes train operation without a driver. It is anticipated that this paper will be helpful for the analysis of ATS functions, ATO functions and EI function in the train control system.
