Opis:
The article presents an analysis of the economic and transport connections between the Łódź and Świętokrzyskie regions, in particular between Łódź and Kielce. Shortages in the railway network, which make it impossible to effectively use railway transport for both passenger and freight transport, were identified. An analysis was also performed concerning the use of opportunities arising from the course of the Trans-European Transport Network (TEN-T) through the territory of both regions. A program of necessary infrastructure investment was also proposed.

Opis:
Large-scale distributed transportation systems can pose various risks in terms of fatalities, environmental pollution, or loss of property. In particular, accident where a vehicle carrying large number of passengers is involved may pose a high risk with respect to human casualties, moreover it will immediately raise a public and political concern. This is an issue in case of maritime transportation systems (MTS), as the biggest ships nowadays can carry up to 8500 people at once (m/s Oasis of the Seas). Thereby lot of effort has been put to increase safety of ships carrying passengers; however the holistic approach to model and manage the risk existing in the MTS is still missing. This paper makes an attempt to fill this gap, by presenting a data-driven model evaluating risk level in the existing MTS and by introducing a systematic methodology for mitigating the risk. Moreover the MTS operating in the Gulf of Finland under non-ice conditions is addressed, where heavy passenger traffic is observed.

Opis:
The process of monitoring vehicle traffic and detecting traffic incidents and traffic obstructions requires access to information from sensors located at various points of monitoring and data acquisition systems constituting elements of contemporary Intelligent Transportation Systems (ITS). Unmanned aerial vehicles (UAVs) are increasingly becoming an element of ITS used in reconnaissance, preventive or rescue operations. Ensuring the efficiency of transportation in conditions of increased traffic requires providing users with multimedia information about: meteorological conditions prevailing on roads, traffic, current events and difficulties, and information on the availability of parking spaces. In each of the mentioned cases, the reliability and quality of information provided with the use of UAVs is an extremely important issue. Therefore, the provision of video surveillance services with a predictable level of quality and reliability is an important challenge for UAVs practical implementations. Thus, the fundamental research problem considered in the publication is the analysis of the impact of environmental and technical parameters on the quality and reliability of the UAVs video monitoring service provided in a real operating environment.

Opis:
Various intelligent transportation systems are proposed in different forms of wireless communication technologies. Recently, the importance of visible light communication and free-space optics has been demonstrated in accomplishing vehicle-to-vehicle and infrastructure-to-vehicle communication systems, due to power efficiency, free licenses, and safety for human health. In this paper, a new hybrid relay system supported by free-space optics/visible light communication with two scenarios is proposed. The first one is that the data are transferred from the source to the relay through a free-space optics communication link and are then directed to the destination through a visible light communication link. The second scenario is that the data are transmitted from the source to the destination passing through two different relays to ensure larger coverage. A 10‾⁶ bit error rate is achieved at a distance of 900 m for the first scenario with a remarkable signal-to-noise ratio of ~25.5 dB, while the largest distance that can be covered by the second scenario is 1200 m with a signalto- noise ratio of ~30 dB.

Opis:
Intelligent transportation systems (ITS) are evolving in response to a range of factors, which are discussed in this paper in conjunction with major directions of future ITS development. The technology of cooperation between the various elements of infrastructure and vehicles will determine further evolution of telematic solutions, leading to synergies arising from both existing and new applications, as well as from the advent of the Internet of things in transportation. The next step in the development of such systems is Cooperative ITS. It already has a solid foundation in the European Union’s strategic documents on transportation, and the first implementations are under way.

Opis:
The lack of attention during the driving task is considered as a major risk factor for fatal road accidents around the world. Despite the ever-growing trend for autonomous driving which promises to bring greater road-safety benefits, the fact is today’s vehicles still only feature partial and conditional automation, demanding frequent driver action. Moreover, the monotony of such a scenario may induce fatigue or distraction, reducing driver awareness and impairing the regain of the vehicle’s control. To address this challenge, we introduce a non-intrusive system to monitor the driver in terms of fatigue, distraction, and activity. The proposed system explores state-of-the-art sensors, as well as machine learning algorithms for data extraction and modeling. In the domain of fatigue supervision, we propose a feature set that considers the vehicle’s automation level. In terms of distraction assessment, the contributions concern (i) a holistic system that covers the full range of driver distraction types and (ii) a monitoring unit that predicts the driver activity causing the faulty behavior. By comparing the performance of Support Vector Machines against Decision Trees, conducted experiments indicated that our system can predict the driver’s state with an accuracy ranging from 89% to 93%.

Opis:
Electrified railways are an example of AC single phase distribution networks. A non-negligible amount of active and nonactive power may be related to harmonics, especially for distorted highly-loaded systems. The paper considers the relevance of the harmonic power terms in order to identify distortion sources in a single-point perspective, in line with the approach of EN 50463 for the quantification of the power and energy consumption. Some single-point Harmonic Producer Indicators (HPI) based on harmonic active power direction and nonactive distortion power terms are reviewed and evaluated using pantograph voltage and current measured during several hours of runs in two European AC railways (operated at 16.7 and 50 Hz). The HPI based on active power shows to be consistent and provides detailed information of rolling stock characteristic components under variable operating conditions; those based on nonactive distortion power are global indexes and hardly can operate with complex harmonic patterns in variable operating conditions.
