In this paper, we propose a railway conflict detection and resolution system (RCDRS) for the Korean railway system. First, we review several studies related to RCDRSs. Second, we analyze traffic patterns of five major Korean National Railroad (KNR) lines. We use five measures to characterize each line: track capacity, transportation mode, meet and overtake numbers, traffic intensity, and traffic diversity. Finally, we present an RCDRS schematic and RCDR model for the Korean railway system. We focus, in particular, on a two-phase RCDR model that coordinates all interconnected lines in the global network.
