A railroad signaling system is being developed in Korea, adopting the communication-based train control (CBTC) technology to control the train operation through radio communication. The project is intended to develop the interoperable and interchangeable subsystems as a trial, and will upgrade the existing system by replacing some of subsystems with new ones to be developed. The development activities have been concentrating on the subsystems development without performing sufficient design activities at the system level. This project shall require the integration and test at the system level. To do so, a top-level system specification is needed, which is not available in the current phase of the project. The purpose of this work is to study the problem when design specifications of the subsystems are given instead. A successful test of the integrated system consisting of developed subsystems requires a test and evaluation master plan (TEMP). The TEMP is usually generated during the concept design stage of the system development and addresses test and evaluation activities on a fully integrated basis to see whether the developed system meets the system specification. In this work, we describe how a TEMP can be generated based on the subsystems design specifications instead of the system specification, hi doing so, we have also utilized the system architecture as well as the system operation concept of the existing system.
