Abstract

The paper focuses on a new method for specifying safe software for rail traffic control systems. The presented method is particularly convenient to define typical devices and subsystems used in traffic control, defined as software blocks in which control algorithms are directly applicable. The method uses the object-oriented methodology and the UML language. The program in UML language allows for modelling, verification, functional testing, and simulation in an environment that is typical for rail traffic control. The method takes the software implementation requirements into account, having in mind the safety and control in real time in accordance with the UIC and CENELEC standards and recommendations.
