Simulation of real traffic events at the workstation

Abstract. The article addresses the problems of applying computer simulation to real railway traffic situations. Its role is to enable the training of traffic control and management system users in conditions as close to reality as possible. Train movement simulation is intended to be an element expanding the “Sosna” didactic and research workstation for traffic control and management, created at the Department of Traffic Control of the Faculty of Transport at the Warsaw University of Technology, and in particular the dispatcher control subsystem included in it.1. INTRODUCTION
The rapid pace of global technological development affects all areas of human life, including railways. Computer technologies mean that the implementation of automation systems takes a form diametrically different from traditional relay implementations. Railway traffic control systems are increasingly being expanded and perform more and more functions. Enabling remote control of distant stations brings with it an economically beneficial reduction in the number of traffic personnel. Computer systems can also be easily expanded with a part responsible for traffic management on a fragment of the railway network. All the above-mentioned features of this solution make it increasingly widely used. On the other hand, the construction, operation, and in particular the maintenance of computer-based traffic control and management systems have a completely different form than for mechanical, mechanical-electrical, or electrical systems. For this reason, there was a need to create a workstation
enabling the learning of computer device operation, testing of new solutions, and understanding the connections and relationships between system modules in laboratory conditions.
As a result of these needs, the “Sosna” didactic and research workstation is being created in the laboratory of the Railway Traffic Control Team of the Warsaw University of Technology, intended to be a complete computer-based traffic control and management system. (…)
