    Opis:
    This study is aimed at improving the methods of carriage of passengers by urban transport to improve its reliability and efficiency. It can be achieved by forming back-up bus routes within the existing regular route network for servicing mass passenger-flows. This study theoretically substantiates the impact of back-up bus routes inthe current regular route network on the reliability and efficiency of the transport process. Mathematical models of reservation of regular route network and the assessment of the reliability of passenger transport using different reservation schemes are suggested. Methodological recommendations on the formation of passenger traffic on back-up bus routes and cost reduction on its maintenance, by managing the route speed depending on the loading of the city road network, have been developed. Technical and economic evaluation was conducted to the developed methodological toolkit.

    Opis:
    There is a need for vehicle relocation, whether for delivering new vehicles to their selling destinations, pulling inoperative or damaged vehicles out of traffiic, or removing illegally parked vehicles from the street. The relocation of illegally parked vehicles in the City of Zagreb is done by constantly monitoring parked vehicles or through citizen telephone alerts. The paper analyses the vehicle relocation service of the Zagrebparking company, which, in addition to overseeing car park management in public car parks and garages, is in charge of removing illegally parked vehicles. Due to the cyclic nature of its operations, a high share of empty rides, high vehicle investment costs, small quantities of cargo transported, high fuel prices, and high fuel consumption in the urban environment, Zagrebparking’s Vehicle Relocation Department operates with unnecessarily high costs. In this paper, vehicle relocation efficiency is analysed by presenting indicators of vehicle utilisation as part of a systematic evaluation of the company. Improvements to the current service are also provided.

    Opis:
    The work presents a methodology that allows us to evaluate the effectiveness of the system in accordance with accepted standards in terms of the three components of the “passenger–carrier–department” system, taking into account the interests of each side. The given comprehensive effectiveness evaluation of the urban public passenger transport system shows that a new scientific idea consists in forming fundamentally new sets of indicators for each participant of the system (passenger–carrier–department of transport) that correspond to the conditions of functioning of the urban passenger transport system in Russian Federation. The article presents a classification model for the formation of a basic system of indicators and a functional scheme for grouping and ranking them. The effectiveness of the urban public passenger transport system can be considered separately for each participant in the system from its side, in two directions: horizontal (by year, for example, for an enterprise) and vertical (in the current period for all participants).

    Opis:
    One of the priorities of the EU economy is to create the best possible conditions for the design and implementation of innovative solutions within the scope of energy efficiency. In recent years, there has been quick technological progress in the field of devices having controlled motor drive used for air purification, and from heating plates, which are applied in the eating places, including restaurants and zones for preparing meals in various means of transport. The research conducted by the EU on EcoDesign requirements showed that range hoods at the stage of their use have a considerable potential of saving energy. The introduction of energy efficiency labels to the market has improved the energy efficiency of these devices and accelerated the transformation of the market to implement energy-saving technologies, which according to the experts, may lead to an annual primary energy saving of 27 PJ/year in 2021, which may increase in 2030 to 60 PJ/year. The authors of this publication researched the fluid dynamic efficiency of a selected range hood, showing the necessity of investments in new technologies. Patented original solutions of the range hoods that can be applied, among others, in such means of transport as passenger ships, cargo ships, and submarines having a zone for preparing meals were presented in this article. An environmental aspect in the context of energy consumption was shown during the phase of using the device for air purification, providing many premises and arguments for future constructional solutions for energy management in various branches of transport and more.

    Opis:
    Purpose/reason for writing the paper: Carrying out a cost-benefit analysis of large infrastructure projects in the area of transport causes considerable difficulties and problems in identifying the positive and negative factors of project implementation, and their translation into cash flows generated by the project. The aim of the paper is to present problem solving in the course of financial analysis and economic analysis of an infrastructure transport project. Methodology/approach to problem solving/scope of the study: The scope of the study and the approach to the problem include: • presentation of the role of cost-benefit analysis in the process of assessing the competitiveness of infrastructure transport projects in terms of making decisions about their co-financing from community funds; • characteristics of general assumptions of financial analysis and economic analysis of projects in the transport sector; • discussion of the methodologies of quantification and monetization of socio-economic factors and factors influencing the external environment in the process of assessing the economic effects of a transport project on the regional and national scale; • indication of the latest sources of methodological support for the preparation of cost-benefit analysis (CBA) of the project; • embedding the issues of financial and economic analysis in the context of the requirements for beneficiaries' application for grants from the funds. Arrangements: Different methodologies are used in transport projects to quantify and monetize the impact of individual factors on the external and socio-economic environment. The paper indicates the latest methodological studies, the scope of their application, examples of calculations and recommendations for beneficiaries on how to adjust the information they have to a specific project situation. Practical implications: Adaptation of the Beneficiary to the applicable and recommendation source materials, knowledge of methodologies for conducting analyses increases the probability of reliable preparation of documentation and obtaining a positive decision regarding financial support for the planned investment project. Social implications: Correct and consistent analysis of projects increases the effectiveness of obtaining their co-financing from EU funds. On the other hand, the implementation of modern infrastructure transport projects is a social good that increases the comfort of passengers, reduces the operating costs of carriers, reduces carbon dioxide emissions, noise and local environmental pollution, contributes to saving time and reducing road accidents. Originality/value of the study (for whom?): The paper is directed and will be useful for investors, as well as beneficiaries of community funds, in order to prepare project documentation for the implementation, execution and operation of infrastructure projects in the field of transport.

    Opis:
    This article presents the results of the analysis of waste collection in selected rural and urban municipalities in the Silesian Voivodship in Poland in the years 2014-2018. A new approach has been presented for the evaluation of the economic efficiency of the waste management system including all costs and revenues both for the local administration and the waste collection company in a circular economy context. The results include the impact of significant factors affecting the total cost of collection, which include transportation costs, personal costs, as well as administrative costs, including fees for using the environment and the fee for waste management at the landfill. The mass from the separate collection increased for three municipalities from 2014, showing a positive impact of the new regulations considering secondary raw materials for recycling. In the five years of the study, the variable purchase prices of recyclable materials adversely affected the economic efficiency of the collection, which increased fees charged by municipalities to residents. The increase in costs was significant for the five years included in the study for a landfill fee increase of 40%, for an environmental fee increase of 15% and an increase of waste collection costs above 20%. The main contribution of revenues is the waste collection fee from residents. As a consequence, the municipalities must increase waste collection fees. Due to a much larger number of waste categories and unstable purchase prices of secondary raw materials, waste-collecting companies should pay attention towards reducing transport costs and using human resources more efficiently.
