Abstract
In this paper, we analyze the performance and reliability of the next-generation KRTCS (Korea Radio Train System) network. The KRTCS has been designed to manage and control the overall status of trains including location, speed, stop position, door open/close status and interior monitoring and so forth. System faults of the KRTCS operation can lead to the disruption of smooth train flow, even to terrible traffic accident. Prior to installation we need to assure the reliability of the designed KRTCS system. For this purpose, we simulated and analyzed the KRTCS network using QualNet simulator, assuming the various environmental operation data of train flows and communication faults that can be found in real telecommunication networks.
