6. Conclusions
This paper proposes a new UTCS, in which a train control system is realized in a hierarchical structure of a functional layer, a network layer, and a terminal layer, and discusses its processing method. It has been demonstrated that an existing signal system can be flexibly evolved into an ideal CBTC that does not have a base-point controller. While the CBTC will start, for the time being, with an ATP block system in the form of a minimal system for local railway lines, in order to demonstrate its advantages, I will endeavor to realize this proposal as soon as possible, as it will be effective in enhancing the robustness and competiveness of railway systems. The ATP block system is a good example of realizing the essential control concept.
