We present a novel study concerning the attitudes of road transport enterprises towards a broad application of telematics in operational management in road transportation. The study aims to assess telematics application in road transport and its changes over time while showing the factors most likely to determine the systems’ use. Unobserved categories defined in the technology acceptance model (TAM) are adjusted to measure perceived usefulness, perceived ease of use, and attitudes toward using telematics systems by road transport managers. The study is based on 323 transport enterprises analyzed in two waves in 2020 and 2021. The use of two different time points is motivated by an observed increase in the digitalization of transport documents caused by the COVID-19 pandemic. The empirical findings support the TAM’s usefulness in evaluating IT in transport business management. The findings also reveal that the significantly increased telematics use in 2020 was observed while it was endured. The results are checked for robustness and used for simulations. The study compares managers’ behaviors over time and simulates the effect of individual (observed) variables on unobserved TAM categories.

Transport companies, whose activities have a significant impact on the economy of the whole of Europe, constantly face new market challenges. The high demand for transport services, even in the time of the Covid-19 pandemic, and the introduction of new regulations by the European Union authorities mean that these enterprises have to increase their efforts on competitive foreign markets. Telematics systems play a crucial role in this battle as they enable the acquisition and processing of data characterizing processes in road transport. In this article, the author undertakes the issue of logistic indicators in theoretical frames, as well as their classification and characteristics as the main source of information about processes. This is followed by the analysis of data obtained from a transport company using a telematics system to manage transport processes in the context of ensuring the quality of services. The aim of the study is to demonstrate the significance of selected logistics indicators in terms of improving the quality of transport services. Statistical analysis is used to study the relationships and impact of individual measures in 2019-2020 as a forecasting tool. The result of the research is finding an appropriate link between the measures and using this knowledge as an opportunity to improve the quality of services.

The development of transport systems is largely supported by telematic systems, therefore it is necessary to ensure their high availability and reliability of IT systems. The authors of the article, recognizing this important problem, have developed software for remote management and monitoring of the computer systems used in transport telematic systems. The software uses WMI (Windows Management Instrumentation) technology, which is the Microsoft implementation of Web-Based Enterprise Management (WBEM). The WMI service uses a Common Information Model (CIM) to represent managed network components (i.e. computers, printers, disks, memory, CPUs, processes). All these objects represent a set of information that could be described in a data model and can be stored in the WMI database - CIM repository. In the paper, the authors present the methodology of using this technology and its practical implementation in software. The conducted researches confirmed the great usefulness of this standard in the diagnostics of computer systems used in transport telematic systems.

The analysis of accidents at level crossings showed that a significant number of them have been occurred at the automatic crossings with signalling lights and automatic half barrier crossings. One of the main causes of accidents is that road users do not obey the warning signals at crossings due to excessive waiting time because real speeds of different trains can vary greatly, while approach distance to crossings is determined for the fastest trains with maximum permissible speed. The purpose of this work is the mathematical justifi cation of the method for the level crossing activation time prediction in dependence on the real speed of an approaching train, based on measurements of input track circuits’ impedance at approach section. The investigations have been carried out by mathematical modeling of track circuits’ operation modes during train movement. The relative error of the method has been determined.
