  Abstract

In case of anomalies such as infrastructure failure or train delay, autonomous trains operate efficiently and reliably by adjusting the paths and schedules themselves without the intervention of the traffic manager. To do this, autonomous trains set up a dynamic path within a few seconds in an exceptional situation. There are various algorithms for searching the paths, such as a single-path algorithms and multipath algorithms. Among multipath algorithms, we suggest Dial algorithm for dynamic path search for autonomous trains. The Dial algorithm extracts only reasonable paths using rational conditions. In addition, the algorithm can capture an uncertainty about the travel time of the trains by perception error. Tested on the Yeongdeungpo station of the Gyeong-In line 1, the algorithm searched appropriate paths in a second on a regular and irregular situation.
