This paper analyses the management process of the vessel traffic control on one-way section on navigable canal with the adaptive time-sequential filter (traffic lights). One-way section on canal significantly decreases waterway capacity and requests special attention in control and regulation of the vessel traffic. The vessel traffic is a stochastic variable, and the vessel...
The second part of the paper continues a discussion on the topic of paralel computations in railway dynamics. The algorithms described in the first part of the paper are applied to parallel simulation on computers with multicore processors of six different models of rail vehicles and trains with the number of degrees of freedom from about one hundred to more than 20 thousands. A...
Today, one of the main important tasks is to analyze the states of achievement related to the required levels for marine passenger terminals and their route networks, depending on the influence of the external environment (based on the discretization of processes). This proposal is relevant both to increase the passenger traffic and to change the route network of ferry lines...
For this study, an analysis of a system of transport nodes of the railway and bus service transportation was carried out. A principal scheme of a transport node in typical cities for Bulgaria and a sample flow chart are presented. The categories of basic requirements for transport nodes in cities are also defined. On the basis of a railway system and bus transport nodes in the...
Parallel computations speed up simulation of multibody system dynamics, in particular, dynamics of railway vehicles and trains. It is important for reduction of required time at the stage of new railway vehicle design, for increase of complexity of studied problems and for real-time applications. We consider realization of paralel computations in Universal Mechanism software in...
On the railroads in seismically active regions, the impact of frequent weak earthquakes accelerates the initiation of defects such as wear and tear, cracks and deformation due to fatigue. An analysis of the types and stages of initiation and development of defects preceding accidents at technical facilities has shown that the registration of the beginning of the latent period of...
Flight personnel have various factors that cause high psychological stress during the performance of flight tasks, thereby influencing their psycho-physiological experience, which may be a cause of a breach of air traffic safety. The paper presents the results of an experimental verification of task management under load, which allowed selection of probands from a sample of 100...
In 2018, there was an empirical research conducted in passengers' interest in innovative methods of passenger handling within passenger transport in the Slovak Republic. The research determined the knowledge of passengers regarding new methods, namely, NFC technologies, EMV technologies and ABT technologies. The article defines the methodology of choosing an electronic payment...
Heating systems in diesel multiple unit (DMU) trains often use additional mechanical and/or electrical auxiliary power, increasing fuel consumption, while waste heat is available from the diesel engine. Delivery of waste heat for heating of multiple carriages is analysed as realized in DR1 and D1 series trains, in light of the current standards of passenger comfort and in-depth...
A study has been conducted on the use of alternative energy sources for propulsion of a vessel in inland waterway transport. It is clear that at this stage it is most appropriate to use a vessel designed for short-haul trips between two banks of a ferryboat for passengers and luggage or for recreation and entertainment. On this basis, research has been conducted on a newly...
The carriage of food products, in particular fresh products, is particularly sensitive to transport conditions. The aim of this paper is to examine the effect of trailer conditions on the quality of refrigerated food transport services. Six wireless measuring devices installed permanently in 3 trailers were used for the analysis. The built-in transmitter sensors have enabled the...
The article presents the results of the investigations of turbocharger shaft bearing using different kinds of lubrication conditions (dry friction and lubrication with different kind of oils). In particular, the wear of the turbocharger shaft surface was evaluated. One of the most frequent failures is the seizure of the turbocharger shaft in the slide bearing, causing its...
