This article describes the issues related to the analysis of the reliability-exploitation of power supply systems in transport telematics devices (PSSs in TTDs). This paper characterizes solutions, which are applied in supply systems, and describes a PSS in a TTD from a main source and a standby one. This enables determining the dependencies denoting the probabilities of the system staying in full ability state, safety threat state, and safety unreliability state. A quality analysis of the PSS in TTD was conducted, and the indicator value of the supply continuity quality was evaluated. This indicator allows the demonstration of continuity quality of power supply (CQoPS) dependency on many quality dimensions, not just reliability. An example demonstrates the calculation of CQoPS factor for both the main and the standby power supply, employing three observations, each influencing the quality. The presented considerations in the field of quality and reliability-exploitation modeling of a PSS can be applied as well in other public utility facilities (including those classified as critical infrastructure). The character of functions performed by critical infrastructure facilities demands an operating continuity of these systems at an appropriate level. The co-first authors of the article once again address the issue of determining CQoPS factor, this time on the basis of modeling using mathematical evidence. TTD is an example in this article, because the presented methods can be used in any kind of system, especially in the power source of critical systems.

“…Currently, exhaust emissions and the concentration of harmful compounds are monitored in real time by means of various online and offline tools [33,34]. Air quality management and monitoring are analyzed with the aim of designing new, alternative solutions to improve air quality and eliminate emission sources in an urban community [35][36][37][38]. Despite the use of very ecological solutions, transport is still the main source of air pollution and noise.…”

The aim of the study is to present a methodology for analyzing pollution emissions in a medium-sized city using modern traffic simulations in the aspect of minimizing exhaust emissions. The scope of the research and the methods of analysis used differ from those applied in big cities projects that can be found in the literature, Therefore the progressive elaboration model has been applied methodically to formulate and carry out the feasibility study. To perform microscopic traffic simulations, the software Simulation of Urban Mobility (SUMO—German Aerospace Center (DLR), Berlin, Germany) was applied. Thanks to the simulations, changes in traffic organization were accurately identified in the context of pollution emissions before they were implemented. The proposed approach allows a smooth flow of vehicles and a reduction of exhaust emissions. The experiments, supported by visual modelling of traffic with respect to pollution emissions, were performed on one of the main arteries of the city of Czestochowa (Poland). The results were used to explain the benefits of planned roadworks and convince the city government of the necessity to modernize the communication network.

The features of the functioning of the on-board information systems of a car are considered. Threats to their security are analyzed, and methods for ensuring information security and functional security of on-board information systems are proposed. The design of road networks in the organization of road traffic is one of the factors in ensuring the functional security of modern intelligent transport systems, that is, compliance with such information security attributes as data confidentiality, integrity, availability, authenticity and novelty of data. The security of on-board vehicle information systems is a critical issue in the modern world, as more and more vehicles are equipped with electronic systems that may be vulnerable to cyber attacks. One of the main challenges of protecting on-board information systems is the wide range of devices and technologies used in modern vehicles. Different systems may have different security requirements and vulnerabilities. They may interact with each other in a complex way. Another challenge is that many of these systems were not designed originally with security in mind. They may lack basic security features such as encryption and authentication and use outdated software and protocols that are vulnerable to known attacks. The main types of attacks and threats to the elements of the transportation system that interact with the VANET were identified to analyze the information security of vehicle in-vehicle systems. Based on the theory of fuzzy sets under conditions of uncertainty and using the Fuzzy Logic Toolbox in the integrated Matlab environment, the level of information security of the OBU-VANET system was modeled. The obtained results allowed us to formulate the degree of information security of vehicle operation elements against unauthorized access to data. The results of the study showed that technical communication systems have the highest security level (> 0.7), and vehicles become the most vulnerable in public places.
