The paper deals with the issue of greenhouse gas emissions that are produced by the road freight transport sector. These emissions affect the structure of the ozone layer and contribute to the greenhouse effect that causes global warming-issues that are closely associated with changing weather patterns and extreme weather events. Attention is drawn to the contradictions linked to FAME (Fatty Acid Methyl Esters) biofuels, namely the fact that although their use generates almost zero greenhouse gas emissions, their production requires high levels of energy consumption. The first part of the paper deals with the theoretical basis of the negative impacts of transport on the environment and the subsequent measurement of the extent of the harmful emissions generated by the road freight transport sector. In the methodical part of the paper, the calculation procedures and declared energy consumption and greenhouse gas emissions generated by transport services are analyzed according to the EN 16258 standard. The experimental part of the paper focuses on the application of the methodology to a specific shipment on a specified transport route, where the total energy consumption and production of greenhouse gas emissions is determined. These calculations are based on comprehensive studies carried out for a particular transport company that assigned the authors the task of determining to what extent the declared energy consumption and greenhouse gas emissions change when the type of fuel used is changed.

This paper presents the outcomes of the research focused on the passengers’ subjective point of view on the Integrated Transport Systems (ITS) comparing with the separate non-integrated traffic lines. The research, within project realized in the Institute of Technology and Business in České Budějovice, was performed in several cities located in the central part of the EU where the establishing the ITS has been planned. The introductory parts of the paper contain the theoretical approaches of the given issue. Particularly, the issue of ITS such as, the review of performed ITS studies, information on the realized surveys and the draft of the used model are outlined in these parts. The used model includes two variants of the problem solving: ITS and individual bus. The surveyed criteria include: unproductive time, time of drive and travel fee.In the next two parts of the paper, the application of the model to real traffic conditions is presented and the outcomes of the research problem are emphasized.

This article deals with the basic mathematical methods applied to the determination of the size of traffic flows in an urban area transport network. The methods were applied to the design of a new system of public bus transport in the city of České Budějovice. This article represents the partial outcome of the research carried out by the Institute of Technology and Businesses in České Budějovice.

The subject of the paper is a brief description of the state of bicycle transport in the region of South Bohemia, the analysis of planning and financing its development. The aim of the paper is to outline the issue of cycling infrastructure in urban and interurban planning, especially in view of methods for determining the share of bicycle transport on modal split within the specific area. The paper includes possibilities of obtaining data about bicycle traffic and outlines the steps to perform manual bike flow counting on a specific project in the city of Ceske Budejovice

Road traffic constitutes a key element of modern life, with many individuals behind the wheel each day. Their driving style, specifically how they accelerate and brake, can significantly influence emissions of harmful substances and air quality. Despite the presence of modern cars equipped to reduce exhaust gas components and other emissions, driving style continues to have a substantial impact on air pollution. In the case of aggressive driving, the influence on fuel consumption and emission generation is substantial. Another aspect is the safety of road traffic, as it has been proven that aggressive driving reduces safety. This article focuses on the results of our recent research regarding vehicle emissions during acceleration. We found that even though modern cars are increasingly environmentally friendly, aggressive driving with them can quickly change the perspective on this issue. While the acceleration of a single vehicle may seem essentially negligible, it is crucial to realize that, especially in urban environments, the number of accelerations of road vehicles as a traffic flow is enormous, particularly during peak traffic hours. Furthermore, there are locations where vehicles must decelerate and accelerate consistently, such as certain types of intersections. The goal of the article is to provide an additional viewpoint on monitoring this trend, this time in combination with the road infrastructure itself, with three examples discussed in the article on how these negative trends can be influenced through modifications to the road infrastructure.

The article deals with logistics processes in companies. Logistics aims to optimize material, finance and information flows to optimize overall costs in companies. The first part of the article describes the methods by means of which the processes in companies can be optimized, namely the Vogel approximation method. In the second part of the article, the method is implemented in a particular manufacturing company with the result of distribution route optimization and reduction of operating costs of transport.
