Viktória Cvacho, Radovan Madleňák, Alessandro Pagano, Edward Kozłowski

Communications - Scientific Letters of the University of Zilina 2026, 28(4):A113-A125 | DOI: 10.26552/com.C.2026.050  

In this exploratory study were examined the gender differences in visual attention and stated preferences during the evaluation of battery electric vehicles (BEVs) using eye-tracking. Thirty-two participants (18 men, 14 women) viewed static images of the ten top-selling BEVs in Slovakia while eye movements were recorded across four predefined Areas of Interest (AOIs). Vehicle design attracted the greatest absolute dwell time in both groups. No gender difference reached conventional statistical significance (all p > 0.05), yet medium effect sizes were obtained for brand (d = 0.69), acceleration (d = 0.67), vehicle equipment (d = 0.60) and trunk capacity...

Communications - Scientific Letters of the University of Zilina 2026, 28(4):C84-C94 | DOI: 10.26552/com.C.2026.056  

In this study was numerically assessed electromagnetic exposure from a 2.4 GHz wireless communication system integrated into a motorcycle helmet. Using CST Studio Suite and an anatomically realistic human head model, the localized SAR were evaluated averaged over 10 g of tissue for five helmet shell materials at transmitter powers from 1 mW to 1 W. At 100 mW, polyimide produced the highest SAR (approximately 1.47 W/kg), whereas the carbon fibre produced the lowest (approximately 0.94 W/kg). All investigated configurations remained below the ICNIRP (International Commission on Non-Ionizing Radiation Protection) localized exposure limit of 2 W/kg...

Vitalii Naumov, Assyl Tazhmuratova, Ihor Taran, Yuliia Melnikova, Daniel Kapica

Communications - Scientific Letters of the University of Zilina 2026, 28(4):A126-A136 | DOI: 10.26552/com.C.2026.051  

Synchronized timetables are crucial for public transportation, yet optimizing them remains complex. While Genetic Algorithms (GAs) address this challenge effectively, their success depends on parameter tuning. In this study was examined how the GA parameters affect schedule synchronization, using a stochastic simulation model to evaluate the fitness of alternative solutions. It is found that the larger population sizes improve solution quality, and higher crossover probabilities enhance overall performance. Conversely, increasing mutation rates or the number of attempted mutations reduces the algorithm’s ability to converge on optimal timetables....

Stopped Fraction and Closure Failure in Congested Macroscopic Fundamental Diagrams: A Sumo-Based Simulation StudyCivil Engineering in Transport

Tomoo Noguchi

Communications - Scientific Letters of the University of Zilina 2026, 28(4):D86-D96 | DOI: 10.26552/com.C.2026.054  

Congested macroscopic fundamental diagrams (MFDs) often display scatter since accumulation alone does not fully describe immobilization within stored traffic. In this paper, the stopped fraction, defined as the share of vehicles that are stopped or nearly stopped, is examined as a complementary macroscopic state variable. A compact analytical framework shows why accumulation-only closure can fail when stopped fraction varies at fixed accumulation. The mechanism is tested using the Simulation of Urban MObility (SUMO) platform on a stylized signalized grid. Adding stopped fraction reduces the root mean squared error (RMSE) from 41.32 to 18.79 overall,...

The spatiotemporal redistribution of traffic flows under alternating blocking of channels at a signalized four-leg intersection is investigated using the case of Augustusplatz in Leipzig, Germany. Observations were conducted over three days, with flows recorded in 48 half-hour intervals per day across four directions and four categories of vehicles. For stochastic modelling, the negative binomial distribution, Taylor’s dispersion index (VMR), Shannon entropy, and an approximation based on M/G/1 queueing theory were applied. A mathematically grounded framework for the real-time network control is proposed, highlighting the necessity of adaptive...

Communications - Scientific Letters of the University of Zilina 2026, 28(3):A73-A82 | DOI: 10.26552/com.C.2026.043  

In the development of Global Navigation Satellite System (GNSS) Positioning, Navigation, and Timing (PNT), short-lived, fast-growing ionospheric storms (lasting up to three days) were assumed to constitute a single, uniform class of space weather events. To challenge this premise, here is presented a circular analysis of single-frequency commercial-grade Global Positioning System (GPS) horizontal positioning errors in the mid-latitude region during four observed storms (one in 2015 and three in 2017), revealing significant heterogeneity. Maximum positioning errors reached 7.495 m in March 2015, but peaked at 4.261 m, 4.387 m, and 3.948 m during storms...

Communications - Scientific Letters of the University of Zilina 2026, 28(2):F18-F30 | DOI: 10.26552/com.C.2026.029  

Increasing disaster frequency intensifies the need for rapid, location-specific information in crisis management. A Virtual Operations Support Team (VOST) can enhance situational awareness by verifying open-source data, but these outputs are rarely transformed into resilience indicators. In this paper is presented a framework that maps verified VOST outputs and metadata to indicators for road critical infrastructure resilience and links them to the crisis decision cycle. A preliminary test on media data (1 Aug-31 Dec 2024; n = 2,045) confirmed a stable baseline and clear peaks usable for management-defined thresholds and trigger actions. The framework...

Communications - Scientific Letters of the University of Zilina 2026, 28(2):C47-C56 | DOI: 10.26552/com.C.2026.028  

Lithium-ion batteries power light electric vehicles such as electric bicycles, but end users typically lack reliable information about true battery health and instead rely on misleading indicators of remaining charge. In this paper is introduced a novel external plug-and-play diagnostic module that connects between the standard charger and a battery of a light electric vehicle. The system uses a precise discrete-time energy integration method during standard charging. It captures dynamic current fluctuations and estimates battery health from the partial charging data. Experimental validation on multiple battery packs demonstrates that the proposed...

The development of a country's economy largely depends on the pace and efficiency of construction work, which, in turn, is determined by the extent to which innovative technologies and techniques are used. This work is devoted to justification of the basic parameters and the development of a new working body for a machine for cutting joints in road surfaces. A design with cycloidal motion is proposed, which intensifies the destruction process due to the vibrational impact of the cutters on the material being processed. The use of such a working body provides a vibrational effect, increases the cutting speed, and reduces the energy consumption of the...
