  Abstract

In this paper, we propose a track switching algorithm for the train-to-train communication-based autonomous system. For efficient track switching, the minimum semaphore area reflecting the track switch and point machine characteristics is defined as the track switching area. The proposed track switching algorithm does not use the existing complex interlocking logic any more, and distributes the track segment and track switching areas exclusively among trains by considering them as both shared resources and semaphore areas that cannot be occupied by two ore more trains. Through simulation, we analyze the effects of various switching operations in various speed environments and show that the proposed algorithm performs better compared with the conventional CBTC. Since the proposed track switching algorithm for autonomous train system does not use complex interlocking logic, it can be expected to reduce the construction cost by eliminating the ground server like the existing EI while providing performance improvements.
