Opis:
The article presents the possibilities of using unmanned aerial vehicles in air transport. The use of UAVs in the airspace has become widespread, despite many implemented legal regulations, there are many incidents that threaten not only aircraft during the flight, but also the airport infrastructure. The potential threats and the chances of implementing remedial measures were analyzed. An attempt to evaluate the possibility of maintaining aviation safety at an appropriate level in the conditions of UAV operational conditions has been done. The main research problem was defined as follows: How would implementing unmanned aerial vehicles into the air transport system influence the acceptable level of safety? The article uses theoretical methods such as: system analysis, analysis and synthesis in the field of literature, analogy, comparative method. In terms of empirical methods, an original diagnostic survey was carried out, based on a selected group of people related to the explored topic. In addition, the observation method was used by the feedbacks and observations of the group of air traffic controllers from civil airports (located in Poland). The article describes the current transformation of air transport, taking into account the planned modernizations. It presents the Pansa UTM system as one of the countermeasures, monitoring and securing the movement in the airspace. Furthermore, the transponder issue was raised in relation to the enhancement of the UAV identification system, with a detailed explanation of the importance of the TCAS (Traffic Collision Avoidance System). Referring to the prospects for the development of air transport, the latest design concepts for cargo drones were presented. The issue of full transport autonomy of UAVs was analyzed based on the requirements of legal regulations. The comparison of benefits and threats in conjunction with the conducted empirical methods allowed for the development of conclusions confirming the research hypothesis and indicating the possibility of using remedial measures in the process of UAV evolution.

Opis:
Every year too many people lose their lives and health on Polish roads. At best, it only ends with damage to their cars. The number of accidents is very high. Despite the construction of new, safer roads, the number of collisions continues to rise, and death, every year, is suffered by about three thousand accident participants. On average, forty-one thousand people are injured annually. The main causes of accidents are failure to adjust speed to prevailing conditions or traffic regulations, driving under the influence of alcohol and random events, as well as the technical condition of the vehicles. The purpose of the article is to answer the question of how the technical condition of the vehicles affects traffic safety. For this reason, an assessment of the technical condition of vehicles during a periodic examination at a vehicle inspection station was made. Based on the study, it can be concluded that the largest percentage of defects detected during the examination is in the tire 40% and steering 40%, defects that are particularly important from the point of view of traffic safety, which were demonstrated during the examination.

Opis:
Following the events related to the pandemic and the war in Ukraine, increasing air traffic also increases turnaround agents' activity at airports. Turnaround operations are among the critical activities performed at airports, which must be characterized by punctuality and accuracy of the elementary handling operations. Lack of punctuality in ground handling causes delays in air traffic. On the other hand, a lack of accuracy can also cause disruptions that can turn into aviation incidents. Achieving punctuality and accuracy in aircraft handling is possible by minimizing the resulting disruptions during such handling. The safety management system (SMS) assumes activities to reduce the causes of potential incidents. In the turnaround process, the human factor, the technical aspect, and compliance with existing procedures are significant. The authors have extensively analyzed the disruptions arising during ground handling, learning its causes and effects, which will help avoid adverse events. Occurring disruptions can cause delays in the execution of flight operations but can also cause aviation incidents. Therefore, the authors focused on ground-handling disruptions that can cause adverse aviation incidents. The article presents the interference analysis results as an Ishikawa diagram. Using the FRAM method, an analysis of possible disruptions during the baggage handling process was carried out.

Opis:
The increase in the use of sea water is the basis for the development of the existing security systems in given areas. Monitoring the navigational situation in a given water area is one of the most important tasks aimed at ensuring the necessary level of safety in maritime traffic. Marine surveillance systems at sea are used for this purpose. As an interesting approach related to the study of the movement of vessels, this paper proposes a method based on the measurement of physical field disturbances generated by objects moving in the sea water. These disturbances can be referred to the upper (air space) and lower (underwater) hemisphere. In the upper hemisphere the motion of the object generates disturbances of the thermal field while in the lower hemisphere disturbances of the acoustic, hydrodynamic, magnetic, electric and seismic fields are generated. Detection of the floating objects and determination of movement parameters is realized mainly by active systems. There are radiolocation systems in the upper hemisphere (radar systems) and echo ranging systems in the lower hemisphere (sonars and echosounders). Monitoring of the upper hemisphere of sea vessels traffic is conducted in a comprehensive manner. The lower hemisphere is in the most cases omitted. Therefore, it is recommended to develop underwater observation systems as a source of additional information about floating objects and thus complement the existing systems used in navigation. However, at present, de spite the technological progress, there is a noticeable lack of the comprehensive solutions in the area of monitoring the vessels movement in the underwater space. Therefore, appropriate action should be taken to recognize this technology gap and increasing the safety of vessel traffic. The aim of the article was to present a fully passive, mobile underwater observation system that uses a number of sensors to monitor the underwater environment parameters, the research methodology and analysis of the obtained results. The method of deploying the measurement system at the selected geographical position and the measurement method are described. Based on obtained results, the analysis of sound pressure disturbances caused by passing ships was performed. A feature extraction method was developed to identify a passing vessel based on low frequency signal parameters.

Opis:
Reduction of ecological risks of shipping is a challenging task that requires methods of legislative and regulatory control, organizational measures, and technical and technological support. Furthermore, the matter concerns not only the reduction of possible risks but also the level of existing impact on the marine environment because of exhaust gas emissions by ships, discharge of waste and ballast water, as well as control of ecological consequences of accidents. The purpose of this study is to analyse possible sources of environmental impact during ship operation cycles, identify significant risks, review existing potentials to reduce the risk of ship accidents and their environmental consequences, and develop solutions to existing problems. This study offers results, which can serve as the initial basis for the formation of comprehensive measures on the reduction of environmental risks, and consequences of possible accidents for the environment caused by ships and international shipping.

Opis:
The year 2022 was marked by economic risks with potentially very sensitive impacts for countries in the Black Sea region. Given the limited capacity of Ukrainian ports, as well as the sanctions imposed on Russia, due to ongoing conflict, it was necessary to identify new destinations capable of taking over the flow of goods that normally went to the countries involved in this conflict. In addition to the risks specific to maritime transport, the risk of armed conflict comes with new challenges that can also materialize in the form of environmental impact. To analyze this potential impact, the study is being focused mainly on the analysis of the pollution risk generated by the emissions caused by the vessels calling the container terminal CSCT, located in Constanța harbor, and the emissions generated by the vehicles moving in the terminal. As estimated from the start all levels of pollution have increased, with the level of CO2 increasing from 11072.7 tons in 2021 to 11915.7 tons in 2022. The NOx emissions have a similar trend, as well as the other emission level measured and calculated.

Opis:
Design and construction of container ships follow consolidated requirements, with standard consideration of fire management. Indeed, cargo fires can have important consequence on crewmembers and cargoes, as well as impacting coastal zone and marine environment. Innovative strategies include prevention of events and mitigation of consequences. Digital solutions, providing with situational pictures onboard and around the vessel are fundamental for new fire management solutions, seamless and integrated into the vessel IT infrastructure, according to IMO regulations and the recent EMSA CARGOSAFE Report. The assessment of these solutions requires theoretical evaluation, validation activities in simulated environment and demonstration activities in real environments, with use cases to prove feasibility and benefits. This paper, after a review of traditional preventing and mitigating solutions against fire and an analysis of container ships fires, proposes applicable innovative technologies and operational measures, emerging problems for their potential implementation and requirements for virtual and real tests design.

Opis:
A hardware-software system has been implemented to monitor the environmental state (EnvState) at the site of railway (RY) accidents and disasters. The proposed hardware-software system consists of several main components. The first software component, based on the queueing theory (QT), simulates the workload of emergency response units at the RY accident site. It also interacts with a central data processing server and information collection devices. A transmitter for these devices was built on the ATmega328 microcontroller. The hardware part of the environmental monitoring system at the RY accident site is also based on the ATmega328 microcontroller. In the hardwaresoftware system for monitoring the EnvState at the RY accident site, the data processing server receives information via the MQTT protocol from all devices about the state of each sensor and the device's location at the RY accident or disaster site, accompanied by EnvState contamination. All data is periodically recorded in a database on the server in the appropriate format with timestamps. The obtained information can then be used by specialists from the emergency response headquarters.

Opis:
Walking is a basic form of activity for every human being and has many advantages, including health, economic and environmental benefits. Every journey made using various means of transport begins and ends on foot. As is well known, the group of road users particularly exposed to the risk of serious injury in road accidents, apart from cyclists, also includes pedestrians. These are the so-called vulnerable road users. Pedestrians are a group of road users that is often deprecated by many drivers of motor vehicles, but very important in road traffic. Pedestrian injuries and pedestrian fatalities have enormous social and economic consequences. The problem of high pedestrian risk on Polish roads is well known and has been widely described in the scientific literature last few years. However, the reasons for this state of affairs have not been fully explained, as evidenced by the statistics of road traffic incidents. Despite many studies in this area, the causes indicated in the research often differ depending on the area of analysis, the environment in which the incident took place, location, participants of the incident, environmental conditions, behaviorism and many other features. Therefore, the main goal of the article was to determine the factors influencing the formation of fatalities in road traffic accidents among pedestrians in accidents involving pedestrians and motor vehicles in the Silesian Voivodeship (Poland) in 2016-2021. The logit model presented in the article allowed for the conclusion that the main attributes influencing the increasing the risk of pedestrian death in road accidents involving a pedestrian with a motor vehicle include such features as driving under the influence of alcohol by the driver, exceeding the speed limit by the vehicle driver, when the road incident involves a heavy vehicle (truck, bus), a pedestrian is a male, pedestrian is over 60 years old, is under the influence of alcohol, the incident took place outside built-up area, at night, i.e. from 10:00 p.m. up to 6:00 a.m, in other than good weather conditions. The obtained results can be used in various activities, campaigns aimed at improving the safety of pedestrian traffic in the area of the analysis.

Opis:
This study aims to improve an earlier safety analysis of port and maritime transportation systems in two cases. The first case does not consider outside impacts and the second case operates under the assumption that they are impacted by their operation processes. New and original suggestions on separate and joint system safety and operation cost optimization are also described and future research is also outlined. Probabilistic modeling methods are used as the research methods. The proposed research procedures enable the determination of the safety function and risk function for the port oil terminal critical infrastructure and the maritime ferry technical system in both examined cases, based on the strictly exact statistical data about their operation processes and on the improved approximate evaluations of their components safety parameters through expert opinion methods that originate directly from the users of these systems. Other proposed practically significant safety and resilience indicators are the mean lifetime up to the exceeding of a critical safety state, the moment when the risk function value exceeds the acceptable safety level, the intensity of ageing/degradation in both cases, the coefficient of operation process impact on system safety, and the coefficient of system resilience to operation process impact in the second case. As a result of this research, it is originally found that the proposed cost optimization procedures and the finding of the corresponding system safety indicators deliver an important possibility for the system total operation cost minimizing and keep fixed the corresponding conditional safety indicators during the operation. It was also established that the proposed system safety optimization procedures, and corresponding system operation total costs, deliver an important possibility for the system safety indicators maximization and keep fixed the corresponding system operation total costs during the operation.

Opis:
The maritime industry plays a crucial role in the global economy, with roughly 90% of world trade being conducted through the use of merchant ships and more than a million seafarers. Despite recent efforts to improve reliability and ship structure, the heavy dependence on human performance has led to a high number of casualties in the industry. Decision errors are the primary cause of maritime accidents, with factors such as lack of situational awareness and attention deficit contributing to these errors. To address this issue, the study proposes an Ant Colony Optimization (ACO) based algorithm to design and validate a verified set of instructions for performing each daily operational task in a standardised manner. This AI-based approach can optimise the path for complex tasks, provide clear and sequential instructions, improve efficiency, and reduce the likelihood of human error by minimising personal preference and false assumptions. The proposed solution can be transformed into a globally accessible, standardised instructions manual, which can significantly contribute to minimising human error during daily operational tasks on ships.

Opis:
Road freight transport is one of the main modes of transporting goods in the European Union. This reality puts pressure on carriers to make every transport of goods fast, safe, cheap, and efficient. Based on these requirements, lorry drivers are often forced by their employers to break the current social legislation in the European Union and the rules of the road. Compared to the current social legislation in force in different parts of the world, the European Union rules on driving times, breaks and rest periods for drivers engaged in road haulage and passenger transport are the strictest. An important factor and reason of serious and fatal traffic accidents, extensive damage to goods or property in road freight transport is a driver. This article presents three different types of experiments that were carried out, and the results may help to improve the current situation. The main aim of this study was to verify whether the actual regulations are safe and suitable and compare the results of daily work of professional drivers in two different measurements. Last measurement was conducted with using Eye-tacking technology, which aimed to verify impact of experiences on the reaction times of drivers. The authors believe that the results of individual measurements can contribute to increasing safety in road freight transport with preparing future extended studies and proposing the possible changes of current regulation.

Opis:
Women, particularly in developing countries, rely heavily on public transport for their daily commute. This study explores the safety and security of women using ride-hailing services in Gauteng. Specifically, the study seeks to understand women’s experiences using ride-hailing services, which might influence their mobility. This study employed a constructivist research philosophy, utilizing qualitative, semi-structured interviews to explore the experiences of women who use ride-hailing services. The study findings reveal several disturbing incidents reported by female passengers using ride-hailing services; however, it is important to note that not all drivers exhibit inappropriate behaviour. Some drivers make inappropriate remarks, while others exhibit rude behaviour. The study found that some drivers use longer routes, leading to higher fares, which can be seen as exploitation. The study also reports some incidents where ride-hailing drivers almost kidnapped some female passengers, indicating a severe safety concern. The study contributes to the ongoing discourse on gender and transport studies, providing empirical evidence on the experiences of women using ride-hailing services in Gauteng, South Africa.

Opis:
In this paper a programmable steering machine (PSM) and the lightweight electric powered vehicle, designed and made at the Kazimierz Pulaski University of Technology and Humanities in Radom (UTH Radom) have been presented. Both these technical objects are the result of the project carried out by the Student Research Group “Turbodoładowani”. The steering machine has been developed with the programmable algorithms allowing to execute a controllable movement of the vehicle steering wheel. After execution, the system does not need an interaction with the driver. For this reason, a higher repetition of the vehicle traction measurements can be achieved. Such confirmation obtained in tests within which the time waveforms of rotation angle of the steering wheel by a set value of 45, 90, 180 and 360 degrees was recorded. In particular, the accuracy index for mentioned test conditions was calculated. Obtained results, expressed by the average value of the sensitivity index were lower than 2% within the tests carried out for ±45 degree maneuvers. In case of other tests i.e., for ±90, ±180 and ±360 degree maneuvers the accuracy index value was lower than 0.3%. In this way, it was confirmed that the tested PSM reached the appropriate operating parameters necessary for vehicle traction tests.
W artykule przedstawiono programowalną maszynę sterującą (PMS) oraz lekki pojazd o napędzie elektrycznym, zaprojektowane i wykonane na Uniwersytecie Technologiczno-Humanistycznym w Radomiu (UTH Radom). Oba te obiekty techniczne są efektem projektu realizowanego przez Studenckie Koło Naukowe „Turbodoładowani”. Maszynę sterującą opracowano z programowalnymi algorytmami pozwalającymi na wykonanie sterowanego ruchu kierownicą pojazdu. Po wykonaniu system nie wymaga interakcji z kierowcą. Z tego powodu można uzyskać większą powtarzalność pomiarów trakcji pojazdu. Potwierdzenie takie uzyskano w badaniach, w których rejestrowano przebiegi czasowe kąta obrotu kierownicy o zadaną wartość 45,90, 180 i 360 stopni. W szczególności obliczono wskaźnik dokładności dla wspomnianych warunków testowych. Uzyskane wyniki wyrażone średnią wartością wskaźnika czułości były niższe niż 2% w badaniach przeprowadzonych dla manewrów ±45 stopni. W przypadku pozostałych badań tj. dla manewrów ±90, ±180 i±360 stopni wartość wskaźnika celności była mniejsza niż 0,3%. Potwierdzono w ten sposób, że badany PSM osiągnął odpowiednie parametry eksploatacyjne niezbędne do badań trakcji pojazdu.
