Test environment for computer-based railway traffic control systems

The article addresses the issue of developing a test environment for computer-based railway traffic control systems. One method that allows for this is the adaptation of a testing system standardized by ETSI (European Telecommunications Standards Institute). This standard uses the TTCN-3 (Testing and Test Control Notation) language to describe an abstract test system. The article presents the architecture of the test system, as well as an example of using the TTCN-3 language for testing computer-based railway traffic control systems.Computer-based railway traffic control (RTC) systems widely use network technologies to create distributed structures. In such cases, the issue of testing systems both during the production phase and during their operation becomes particularly important. For computer-based RTC systems, where data exchange is carried out using computer networks, TTCN-3 (Testing and Test Control Notation) can serve as a test language. It allows for the construction of a test environment, including a test system and active control of distributed railway traffic control systems [1]. (…)
