Innovation of the railway signalling system utilizing the network and the autonomous decentralized technology

Amount of construction about railway signalling system is steadily increasing to improve the transport service for the customer. But, at present efficiency of signal construction is very low. For example it is caused by that the period for the construction is limited to very short time at mid-night or flexibility of the signalling system is low from its system architecture. To solve these problems innovative railway signalling system utilizing network and autonomous technology are proposed. In this paper, first the network signalling system which is the basis of this innovation is described. Next, integrated logical controller which applied autonomous decentralized architecture to its software is proposed as future plan.
