車上装置を主体とした運行システムにおける自律的な進路制御方法

抄録

In the railway industry, there are needs to develop technologies that contribute to automatic driving and driverless operation in order to address the shortage of drivers due to the declining population and to improve the safety of train operations. Therefore, in order to expand the benefits of driverless operation, Railway Technical Research Institute is investigating an autonomous decentralized train operation system in which the train itself collects information necessary for operation, communicates directly with signal equipment such as turnouts and level crossings, and controls speed while confirming safety.

In this paper, we report on a method of autonomously configuring safe route by onboard equipment. In the conventional method, blocks and routes are secured by wayside block equipment and interlocking device. On the other hand, in the proposed method, the on-board device compares the routes with passage time of its own and other trains and secures the block if its own train is judged to have priority. We also analyzed the effects of control equipment malfunctions on safety.
