(University of Zilina, 2021) Raji, Bashiru Adisa; Dina, Adeolu; Solanke, Muse Olayiwola; Alli, Taiwo Kareem
Tracking the influence of service improvements on passengers particularly is an important component of transport management. This study examined the characteristics of intercity travellers in the Economy Class Units (ECU) and recently introduced Diesel Multiple Unit (DMU) service within the Lagos District Nigeria Railway Corporation in southwestern Nigeria. A structured questionnaire was randomly administered to 1206 passengers traveling on these trains over two months with analysis in-volving the use of the regression model. The findings of the study indicate the socio-economic characteristics of passengers accounted for about 90.3% and 88.2% of the variation in volume trips made by passengers using DMU and ECU service respectively. Significant socio-economic predictors of trip volume on DMU train are Occupation (0.137), Vehicle Ownership (0.218), and Type of vehicle (0.218). On the other hand, significant socio-economic attributes of ECU passengers that affect trip volume are Age (0.274), Education (0.970), Occupation (-0.918), Income (0.435), Vehicle Ownership (0.249), and type of Vehicle (-0.165). The result further indicates Trip Purpose explained 83.5% and 86.7% of the variation in the trip volume of both services. The trip purpose that significantly influences the volume of trips on the ECU trains are Business (0.210), Shopping (0.447) Leisure (-0.463), and other trip purposes (0.775). For the DMU train, only Other-trip forms of purpose (0.753) is significant in explaining the volume of passengers using that service. The study shows similarities in the use of the two services while several useful recommendations on ways to improve both services of the corporation were proffered.

(University of Zilina, 2020) Ogunbiyi, Margaret Emem; Onifade, Morakinyo Kehinde; Afolabi, Oluwaseyi Joseph; Oroye, Olufemi Adebayo
This paper examines solid waste transportation in Ado-Odo/Ota Local Government Area of Ogun State. Adequate transportation of solid waste is one of the major challenges of waste managers in Nigeria because of inherent factors ranging from dearth of transport infrastructure to poor attitude of residents. Data were collected through the aid of questionnaires, personal observations, visitations to some villages and towns as well as dumpsites. The questionnaires were divided into two parts: household respondents and solid waste management staff. The data obtained were analyzed using Descriptive Statistics, Factor Analysis and Item Analysis. From the analysis of the data obtained from household and waste management respondents the mean and standard deviation reflect high degree of correlation and concurrence. From the principal component analysis of both the household respondents and waste management staff, there are two principal factors respectively that should be given higher consideration in solid waste management in Ado-Odo/Ota Local Government Area. These factors include waste collection and disposal method, frequency of collection and reliability of waste vehicles. Based on these findings, the study concluded that attitudinal change on the part of the household, government intervention on road maintenances, and adequate maintenance of PSP vehicles will go a long way in reducing the heaps of refuse and indiscriminate dumping of solid wastes in the entire vicinity of Ado-Odo/Ota Local Government Area in Ogun State, Nigeria.

(University of Zilina, 2019) Dávid, Andrej
Automation of handling systems in the container terminals of maritime ports has become one of the most important changes that happened in maritime transport since the first voyage of a container vessel in 1956. Nowadays, new automated terminals are being built in the world. Most of them are located in Europe, then in North America and the Far East. Automated guided vehicles, automated straddle carriers or automated stacking cranes have replaced handling devices that were manipulated and were controlled by port workers in the container terminals. The basic goal of the paper is to focus on the advantages of this progressive system that is based on the increase of the output of the container terminals, the reduction of downtimes or accidents during handling of containers.
Benefits of Autonomously Driven Vehicles
(University of Zilina, 2016) Rievaj, Vladimír; Mokričková, Lenka; Synák, František
The vehicles with high grades have the embedded systems which are essential for the operation of a vehicle with higher standard of safety. This way road transport can significantly closer to the safety of rail and air transport because the error of driver is the main cause of the accident. The expected benefits of autonomous vehicles are their ability to observe small distances between the vehicles. Based on the information from stationary sources and vehicles running near adjust their route and speed of travel so as to minimize delays in congestions. This ensures greater continuity of driving, reducing consumption of vehicles and therefore the production of greenhouse gases from road transport. If the vehicles are capable of autonomous driving is achieved higher average speed and they have been removed the mandatory brakes within driving. It achieves the higher performance of individual vehicles and thus fewer number of vehicles on the roads and less traffic congestion.
Calculation of total costs when ensuring railway passenger transport at the Bratislava to Banská Bystrica line
(University of Zilina, 2017) Záhumenská, Zdenka; Gašparík, Jozef; Škorupa, Milan; Vladimirovich Kurenkov, Petr
Nowadays, great emphasis is placed on the quality of services provided in rail passenger transport, which is influenced by several factors. The competition between operators in the public tender when ordering paths in long-distance rail passenger transport is very significant. The aim of this article is to analyse steps of the Slovak government in the announcement of the first public tenders to provide subsidized transport of a selected line and to determine conditions for this tender. During 2015, Slovak Ministry of Transport began to take steps towards the liberalisation of the long-distance domestic rail passenger service on the Bratislava to Banská Bystrica line, which opened up the market for domestic passenger services to a new railway company. The Bratislava to Banská Bystrica line was chosen because of the provision of sufficient transport performance and passenger flows. The liberalisation process of the Bratislava to Banská Bystrica line is still ongoing, and has entered competitive conditions and criteria stage, although the tender had yet to be concluded in 2015.

Comparative Assessment of CI Engine Response
(University of Zilina, 2014) Ambrozik, Andrzej; Ambrozik, Tomasz; Kurczyński, Dariusz; Łagowski, Piotr
The response of the piston internal combustion engine provides an important indicator to assess the engine ability to adapt to constantly varying load conditions in its operation. It is the main criterion by which engines powering automotive vehicles are evaluated. It also affects road safety. The engine response depends on the profile of the curve that shows changes in the engine torque as a function of the crankshaft rotational speed. The paper presents a comparison of CI engines representing different generations with respect to constructional level. The engines that underwent comparison were equipped with the fuel system with a rotary injection pump and with Common Rail fuel system.

Comparison of R&D within the Visegrad countries
(University of Zilina, 2015) Madleňák, Radovan; Al Kassiri, Mário
Knowledge is learning, as short explanation meaning. Knowledge is gained by long-term experience, continual learning, as well as by finding the right solutions for the issue. The longer we take the time for solving and analysing the issue the better given solution can be obtained. Knowledge is very closely linked with creativity, as Einstein had mentioned, Creativity has no boundaries, but it is a process that requires knowledge of the problem and longer term experience according to research. The knowledge economy is very important for growing economies. Countries which are rich of raw material resources yet don't need to be countries which are part of developed countries. This might be caused by not supporting the ideas of innovations, education, or research and development. Simply we can say that growing economics is based on knowledge.
