According to statistics, the marine passenger transportation sectors (both cruise lines and ferry lines) show a significant increase of passenger traffic and the intensity of ship routes. But new features of the conditions for passenger traffic growth require the development of new methodological transport models for cruise and ferry networks and new practical forecasting methods...
In this paper, aircraft safety of complex critical systems in terms of the automation and safety has been investigated. We think, due to the automation, the role of operators has shifted from active control to passive monitoring. Performing this last task even might be more difficult because of the monotony and needs of realization of the active control in emergency situation...

The purpose of this paper is to describe and analyse a mechanical device designed to enhance the safety of a motor vehicle. The topic is addressed by analysing the method of absorbing kinetic energy during a car collision with an obstacle. The article analyses opportunities to convert motor vehicle’s kinetic energy into another type of energy in the case of collision. For this...
This study aims to develop and validate a measurement scale for internal capability and logistics outsourcing. Regarding the goal of this study, data were obtained from 180 respondents who are currently performing logistics outsourcing in different fields in Sudan (oil industry, telecommunications, logistics services and manufacturing). Depending on the questioner technique, a...
The article concentrates on road safety in Poland, which is one of the countries with a high number of fatalities in European Union. As the passenger cars are the mostly involved in traffic accidents with fatalities, this type of vehicles was analyzed to check relationship between age of the vehicle and its involvement in accidents with fatalities. This type of scientific...
The paper presents a technical station model using the graphical evaluation and review technique – GERT. The network model reflects the operation of trainset service in compliance with the technology and technical equipment as well as interaction between technological systems at the service stations that are different by track development but connected to big passenger stations...
The article describes the design of a system used for the improvement of the adhesion of locomotive wheels to rails; the principle of which is based on the electromagnetic feeding of the contact area with the bulk material that has magnetic properties and high hardness (iron scale Fe3O4 and magnetite FeO×Fe2O3). The experimental results of laboratory and bench tests confirming...
The main parameters describing the interaction between a tire and the road are forces transmitted by a tire. This paper presents experimental and theoretical research of mechanism of force transmission between a tire and slush-covered pavement. The experimental research was conducted in the internal drum test facility at the Karlsruhe Institute of Technology in Germany. The...
Human-related factors are considered to be the main cause of traffic incidents or accidents, causing 69.70% of the incidents. Several studies have been conducted to identify the relationship between drowsiness or fatigue and driving performance. Furthermore, a number of other studies not only discussed the symptoms causing drowsiness but also tried to investigate related factors...
The paper considers the problems concerning the improvement of passenger transportation process at the expense of the combined operating mode implementation. Efficiency criteria to implement the mixed conveyance forms have been formulated. An extensive approach to determine stopping points, involved in a highspeed route, has been proposed. An economic and mathematical model has...
The paper suggests a method for determining the optimal location of service points (warehouses) based on the method for optimal planning of radiation therapy of malignant tumors. This method enabled us to identify the location of the most optimal number of warehouses taking into account their capacity for the required volume of freight transportation and distance from warehouses...
In modern global conditions, the revival of the economic belt of the Great Silk Road as a whole opens up new significant opportunities for countries along the route to develop the economies of these countries. Nowadays, the main factors for the integration of these countries are logistics, international trade, and tourism. The relevance of the study lies in the very...
The paper is focused on the proposal regarding the regional transport organization within Integrated Transport System in a given territory using the selected multi-criteria analysis methods. Introductory parts of this research study include basic information related to this topic as well as description of the current state of the public passenger transport operation, specifically...
International container transport plays an important role in the exchange of goods between China and Europe, and accordingly, the efficiency of the transportation increases with the organization of special container lines (land and sea). Owing to its geographical location, the territory of Kazakhstan has become one of the main international landlines for passage of container...
This article focuses on road traffic safety in Poland, where the risk of serious injury and death in accident has remained high. We present examples of campaigns on the use of seat belts and child restraints system between 2005 and 2015 promoting positive behaviour in road traffic. Results of self-reported data from survey in real traffic on vehicles’ road user’s behaviour due to...
The use of surface welding with micro-jet cooling allows to control the structure of the surface layer. It is a way to significantly increase the mechanical properties (for example hardness) of the surface layer. The effect of this is to extend the life of the kinematic pair. The main aim of this paper was to determine the influence of using micro-jet cooling for surface welding...
