Modeling Commuter’s Sociodemographic Characteristics to Predict Public Transport Usage Frequency by Applying Supervised Machine Learning Method

Published Online: 30 Dec 2019
Page range: 1 - 7

Abstract

Abstract

Predictive modeling is the key fundamental method to study passengers’ behavior in transportation research. One of the limited studied topic is modeling of public transport usage frequency, which can be used to estimate present and future demand and users’ trend toward public transport services. The artificial intelligence and machine learning methods are promising to be better substitute to statistical techniques. No doubt, traditionally been used econometrics models are better for causal relationship studies among variables, but they made rigid assumptions and unable to recognize the pattern in data. This paper aims to build a predictive model to solve passengers’ classification, and public transport usage frequency using socio-demographic survey data. The supervised machine learning algorithm, K-Nearest Neighbor (KNN) applied to build a predictive model, which is the better machine learning method for dealing with small datasets, because of its ability of having less parameter tuning. Survey data has been used to train and validate the model performance, which is able to predict public transport usage frequency of future users of public transport. This model can practically be used by public transport agencies and relevant government organizations to predict the public transport demand for new commuters before introducing any new transportation projects.

The Effectiveness of a Regional Railway Line - Case Study on the Track Hodonín - Holíč Nad Moravou

Published Online: 30 Dec 2019
Page range: 8 - 15

Abstract

Abstract

The effectiveness of regional railway lines has been a much discussed theme recently mainly in case of lines which are not sufficient per the capacity requirements of carriers, or vice-versa, which are utilised only to a minimum extent. The article deals with the assessment of options how to utilise the railway line Hodonín - Holíč nad Moravou with respect to its inclusion into Revision of Transport Expenses document. Based on the analysis of present operation situation in that border crossing as well as on the analysis of passenger and freight railway transport operation various options of utilising the line have been investigated with respect to operation and economic options of individual alternatives.

International Comparison and Trend of Emissions in the Transport Sector in the European Union and Slovakia

Published Online: 30 Dec 2019
Page range: 16 - 23

Abstract

Abstract

Transport and its major part of transport means is currently based on the internal combustion engine principle. For these engines, the primary energy source is oil, natural gas, coal, biomass and others. These primary energy sources and their processing in refineries and factories are used to produce products that are used to drive engines - fuels. From what energy sources these fuels will be produced and what technology will be used to process and produce them is also an important. This whole process must take the reduction of total emissions into account. Future fuels can be considered synthetically produced diesel or hydrogen, which can later significantly affect the decrease in emissions from their processing, production and subsequent combustion of these more environmentally friendly types of fuels. This article processes analyses and development of basic pollutants, total emissions and energy consumption in the Slovak Republic and the EU. In the second part there is an evaluation of the emissions trend development in transport in the EU and Slovakia.

Application of Railway Safety System Radioblock

Published Online: 30 Dec 2019
Page range: 24 - 27

Abstract

Abstract

This paper focus on description of railway safety system radioblock and its application. Content of the paper describes usefulness of this system on those railway lines, which have been operated according to norm about simplified supervision of railway operation. Theoretical basis of the research is proved by case study on the railway line Číčenice – Volary (Czechia). This railway line is the only railway line with this safety system nowadays. Application of these issues is evaluated from safety and technology point of view. There are some suggestions for other railway lines, which are suitable for radioblock railway safety system.

Development and Current Trends in the Use of Mobile Devices

Published Online: 30 Dec 2019
Page range: 28 - 35

Abstract

Abstract

The paper deals with the analysis of the development of mobile devices and current trends in their use and development. The relevance of the article is in its linking history and present. The article points to milestones in historical development and future trends and development of mobile devices. Today, mobile devices affect all areas of human life, whether private or business. Mobile devices are now able to replace computers and laptops, so the user has the information they always have with them. The development of mobile devices inherently includes systems supporting their functioning, which the article also discusses.
