    In the publication, the authors refer to the study carried out as a part of the research project: “Classification of the Police vehicles according to their destination, taking into account their purpose and standardization of the vehicle central console, in the field of arrangement and installation of ICT systems and the devices controlling special purpose signals”, implemented by a scientific consortium, funded by the National Centre for Research and Development. The described research involved the determination of the optimal location for the central console of the Police service vehicle. The first part of the publication contains partial results of the questionnaire surveys that were carried out among the users of Police vehicles. The second part discusses the research carried out with the participation of the Police officers driving the vehicles. The simulator was used to test vehicles in typical and extreme conditions, located at the Police Academy in Szczytno. The research consisted in the use of an oculometer, installed in the simulator. Conclusions from the conducted research allowed to propose an optimal location of the vehicle central console. The indicated location in the assessment of the research team allows to minimize the risk of the occurrence of hazards, related to the need to take the business vehicle away from the road, and is therefore appropriate to ensure the optimal level of safety for the driver and other road users. The results of the research carried out, after their confrontation with the results of the study conducted by other participants of the research consortium, will allow to propose a solution that can significantly improve safety, ergonomics and comfort of official duties performed by the drivers of the serivice vehicles.

    Opis:
    The MONALISA 2.0 (ML 2.0) project aims to define the Sea Traffic Management concept (STM), where information is shared amongst all stakeholders in the maritime transport chain, including nautical officers, ports, administrations, etc. Thus, a communication and information centered approach for data exchange by System Wide Information Management principles changing from surface-based- to voyage-based-operations has been proposed. Amongst others, testing and verifying the feasibility and benefits of STM and its solutions shall be done in the European Maritime Simulator Network (EMSN), a macro simulation environment for ship handling simulators. This is an open IEEE 1278 standard network protocol enabling interactive communication between distributed simulation environments. Based on an introduction into ML 2.0, the proposed STM concept is introduced, its expected impacts are listed and Key Performance Objectives are derived. The backgrounds on the EMSN are given and it is shown how it can assist in assessing the impact of STM’s Key Performance Indicators.

    Opis:
    Driving is an extremely complex behaviour that is also very difficult to measure. Recently, were conducted research which main purpose was quantification of chosen driving parameters to identify dangerous behaviours. For these research modern apparatus for psychophysiology reactions were commonly used, and experiments were made with the use of the driving simulator. Despite such possibilities, most of the researches over road traffic safety are still conducted with the use of self-reported questionnaires or with subjective evaluation of specialists. During driving process one of the most important aspect is a proper observation of road and its environment. Correct perception is necessary for proper reaction of driver for occurring events. Drivers attention is absorbed not only by the road, other road users and traffic infrastructure, but also by road environment elements like buildings, billboards and advertisements could attract his attention. A key to understand drivers’ behaviour seems to be measurement of his visual activity. To measure it, eye tracking instruments could be used, which allows to track drivers eyeball movements during driving. In Motor Transport Institute were recently conducted studies on drivers’ visual behaviour and indication of some which could be potentially dangerous. There were also indicated some differences over population in visual search strategies. These studies led to identification of some undesirable behaviours which could led to accidents. Following paper presents briefly process and results of chosen Motor Transport Institute research with use of a high-class driving simulator and mobile eye-tracker. Also apparatus parameters and used simulation scenarios were described.

    Opis:
    This paper will give an intro into the technical backbone of the EMSN and derive necessary specifications to allow for objective testing in large scale. Further, it will demonstrate the potential of EMSN as a maritime safety test-bed on the STM case. Therefore, the simulations executed within the EMSN are evaluated regarding their safety level in order to demonstrate the effects of various measures to improve safety. Based on a fuzzy logic approach, numerical Data from the EMSN Data-Tracker is used as an input to assess a present traffic situation from the perspective of a specific ship and outputs a comprehensive safety index developed by expert opinions. The safety index is used to further analyze navigators’ behavior and decisions in different maritime traffic scenarios that are executed within the EMSN.

    Opis:
    Safe shipping is essential for society and different measures are taken to improve maritime safety, for example through implementation of traffic separation schemes, radar surveillance and traffic management concepts. But how can maritime safety be measured to determine the effects of those implementations? In this study, a real-time maritime safety index for a ship is developed, taking into account both the probability of grounding and the probability of collision. The index is developed using fuzzy integrated systems and validated in ship handling simulator scenarios. It uses numerical data from the simulator as an input to assess the present traffic situation from the perspective of a specific ship and outputs a comprehensive index. This paper describes the concept of sea traffic management as proposed and evaluated in the EU funded STM Validation project, the motivation for developing a maritime safety index, the numerical input variables and model properties and also validates the feasibility of the approach.

    Opis:
    In the field of railway transport many activities are taken to achieve higher availability of offered services. A few of them consider more flexible rules of creating and starting trains. This requirement translates into greater complexity of railway traffic opertional management and control (RTMC). At the Faculty of Transport of Warsaw University of Technology classes for students have been conducted for several years with the use of the KSR-EDU stand. Taking into account the described trends of railway traffic nature, the KSR-EDU stand was connected to a simulator of real railway traffic. This connection allows to practice various and more complicated movement scenarios. The article describes RTMC layer model and simulator architecture in general. Two simulation tasks are described in details. The algorithms of simulation tasks for different levels of simulation are presented. In the end the benefits arising from application of the simulation for particular didactic tasks are discussed.

    Opis:
    The continuing surge in commercial vessel sizes is putting increasing pressures on the world’s port authorities to adopt effective expansion strategies to ensure that their asset is able to meet growing capacity demands. Among the key challenges is to assure that correct strategic planning and operational measures are adopted to guarantee safe and efficient traffic not only through its shipping channel, but also at the port berthing facilities. DHI and FORCE TECHNOLOGY have collaborated to develop a novel physics-based vessel traffic management system named NCOS ONLINE. It is capable of taking into account of any relevant vessel constraints such as under-keel clearance (UKC), maneuverability and berth configuration that may constrict the movement of vessels through the channel or operability at berth, facilitating scenario planning and capacity assessment of proven unparalleled accuracy. The system incorporates the accuracy of high-end Full Mission Bridge Simulators with regards to vessel response under power and at berth. The underlying computational engines uses a powerful 3D panel method for vessel response calculations in combination with highly detailed environmental data such as wind, waves and hydrodynamics (water level and currents) simulated by use of MIKE Powered by DHI’s recognized and scientific based computational models. The modular and integrated framework-based system has already been adopted by numerous port authorities, terminal operators and pilots worldwide for strategic port planning, design and 24/7 operational vessel traffic management. The paper focus on presenting the underlying equational framework and validation of the underlying physical response engines and provide a brief introduction to how they are integrated and operated through a series of user-friendly web dashboards.

    Opis:
    Aim: A simulator supporting the training of police officers who process traffic incident scenes is a tool with which we will be able to train traffic police officers in processing traffic incident scenes. The essence of the research and development project presented in this article is providing the trainee with a simulated experience of being at both typical and unusual traffic incident scenes, including those involving mass-casualty incidents, major traffic accidents, or other crisis situations. The simulator will connect the virtual world with the real world, taking the trained person into the virtual world (visualisation of the scene), and allowing he or she to process the scene (visual inspection of the scene, producing reports, providing first aid to victims, etc.). Currently, there are no comprehensive solutions supporting the training process in the proposed way. The implementation of such a tool in the Police training system will allow to improve the quality of traffic-police training, and increase the effectiveness of scene processing. Methodology: The review was prepared on the basis of project documentation and current statistical data on traffic incidents, and selected literature on the subject. We analysed traffic incidents in the last ten years, with particular attention devoted to the number of fatalities and the number of traffic incidents. We demonstrated the complexity of the processing effort by Police officers at the scene, as well as the need to use new technologies for the purposes of training policemen, including in particular simulation systems. Conclusions: The article addresses one of the most important tasks of the Police – which is ensuring road safety – by proving the need to use training simulators in training traffic policemen. By commissioning the construction of the simulator described in the article, the Police confirmed the need to develop the training space using the described tool. Based on the synthetic review of project documentation, we were able to confirm that the implementation of the simulator in the Police education system would allow to improve the quality of training traffic police officers, and could have a positive impact on their work environment. Training people with the use of simulation systems eliminates property damage, and reduces the risk of loss of life and health.
    Cel: Symulator wspomagający szkolenie funkcjonariuszy Policji w zakresie realizacji działań w miejscu wypadku drogowego to narzędzie, dzięki któremu będzie możliwe przygotowanie funkcjonariuszy Policji do wykonywania czynności na miejscu zdarzenia drogowego. Istotą projektu badawczo-rozwojowego przedstawionego w artykule jest możliwość „przeniesienia” osoby szkolonej do miejsca typowego i nietypowego wypadku drogowego, takiego jak masowe wypadki komunikacyjne, katastrofy w ruchu lądowym lub inne sytuacje kryzysowe. Symulator połączy świat wirtualny ze światem rzeczywistym, tj. umożliwi przeniesienie szkolonej osoby do świata wirtualnego (wizualizacja miejsca zdarzenia), umożliwiając jednocześnie wykonywanie czynności w miejscu zdarzenia (inspekcja wizualna miejsca zdarzenia, opracowanie dokumentacji z przeprowadzonych czynności, udzielanie pierwszej pomocy ofiarom wypadku drogowego, itp.). Obecnie nie ma kompleksowych rozwiązań wspierających proces szkolenia w proponowany sposób. Implementacja takiego narzędzia do systemu szkolenia Policji pozwoli na podniesienie poziomu i jakości szkolenia funkcjonariuszy policji drogowej oraz zwiększenie efektywności działań podejmowanych na miejscu zdarzenia drogowego. Projekt i metody: Artykuł został przygotowany na podstawie dokumentacji projektu i aktualnych danych statystycznych dotyczących wypadków drogowych oraz wybranej literatury przedmiotu. Przeanalizowano wypadki drogowe w ciągu ostatnich dziesięciu lat, ze szczególnym uwzględnieniem liczby ofiar śmiertelnych i liczby wypadków drogowych. Wykazano złożoność działań podejmowanych przez funkcjonariuszy Policji w miejscu zdarzenia drogowego, a także potrzebę zastosowania nowych technologii – zwłaszcza systemów symulacyjnych w procesie szkolenia policjantów. Wnioski: W artykule autorzy odwołują się do jednego z najważniejszych działań Policji, jakim jest bezpieczeństwo ruchu drogowego, dowodząc konieczności użycia symulatorów szkoleniowych w szkoleniu policjantów ruchu drogowego. Policja, przyjmując rolę gestora i ubiegając się o budowę symulatora opisanego w artykule, potwierdziła potrzebę opracowania przestrzeni szkoleniowej przy użyciu wspomnianego narzędzia. Na podstawie syntetycznego przeglądu dokumentacji projektowej potwierdzono, że wdrożenie symulatora w systemie edukacji Policji pozwoli poprawić jakość szkolenia funkcjonariuszy policji drogowej i może pozytywnie wpłynąć na środowisko pracy tej formacji.

    Opis:
    This article presents a dedicated kinematic method of determining a safe fairway bend width with a specific turn angle and arc radius as the function of ship parameters and prevailing navigational conditions on the fairway. The assumed approach takes into consideration monoeuvring and navigational components of the safe fairway bend width. The method is based on an analysis of the results of numerical tests conducted on a model representing all physically possible movements of ship's centre of gravity in the bend. The developed method was initially verified on the Ińskie bend, part of the Świnoujście-Szczecin fairway.
