Abstract: The paper analyzes the conditions under which the telematics system operates, with particular emphasis on numerous threats to the physical structure of telematics systems and the correctness of the services they provide. Quality assurance models for information transmission in transport telematics systems have been proposed.Basic traffic shaping mechanisms have been characterized to ensure minimum bandwidth for applications critical to the company’s operations. A traffic shaping method has been presented. This method was used to develop a concept for regulating telecommunications traffic related to the operations of the largest Polish railway carrier. Data exchange in transport is used in management, guidance, and control systems for transport processes, as well as in information systems.
Railway companies have used means of communication for the efficient conduct of rail traffic almost since their inception. It can be stated that communication was a work tool that significantly improved rail traffic management. With the development of the railway network and progress in telecommunications technology, this tool has “reached into deeper and deeper layers of the transport process,” e.g., directing or even controlling rail traffic.
