This contribution discusses the issue of approaching safety issues for newly introduced autonomous rail vehicle operation systems with the GoA3/GoA4 automation level. In particular, the paper discusses the issue of normative requirements for establishing and demonstrating safety requirements that are in place today for railway systems. The paper seeks to define the minimum criteria or processes that should be met and demonstrated in order for autonomous train operation to be accepted as sufficiently safe for commercial operation.

The sustainable development of urban technological and technical systems is closely linked to the acquisition of relevant data and information. Such information is crucial not only for the effective management and administration of these systems but also for identifying critical risk points and monitoring the life cycle of infrastructure. A key element is the use of information modeling and predictive approaches that facilitate continuous monitoring throughout the entire operational phase, thereby ensuring effective maintenance planning. This paper synthesizes various methods and technologies employed in the information modeling of technological systems and explores their application in the modeling and simulation of external factors affecting transport infrastructure. Particular emphasis is placed on the predictive maintenance of technological equipment, with tunnel technology analyzed as a case study a key component of urban transport and technological infrastructure. The primary objective is to demonstrate

The article describes the practical experience of testing a specific ticketing system for public transport based on blockchain technology. The testing aimed to verify the overall functionality of the complex system as well as the correct execution of the functions of its selected parts, which consist of several separately developed but closely cooperating subsystems: blockchain, clearing, and mobile application subsystem with support of bank payment system. Communication between the different parts was implemented through APIs developed for this purpose. The availability of API documentation and the implementation on Linux OS allowed the use of sophisticated tools for testing and performing both manual and automated tests. Performed tests made it possible to detect errors in the program code of the respective components and to provide the basis for their elimination. Applied approaches and tools can be used to test similar complex information-handling systems.
