Special Issue Information

Dear Colleagues,

The aim of this Special Issue of the Energies journal “Energy in Modern Transportation – Problems of the System-of-Systems Approach to Low-Carbon Mobility and Logistic" is to collect current-new manuscripts whose scientific and research topics concern a systemic approach to issues related to low-carbon mobility and logistics. Energy in transport systems plays an essential role in terms of the functioning, efficiency and ecology of transport systems and sustainable urban mobility. Therefore, we invite you to publish studies on the decarbonization of transport and logistics processes in the areas of urban mobility – both in relation to the movement of people as well as the transport of cargo and their storage. The above-mentioned issues are analyzed in the context of both the transport policy and the development strategy of urban areas, as well as in the context of technical means of transport and logistics, including cybermobility and zero-emission personal transport.

Manuscripts that emphasize either method development or applications are encouraged. Both original papers and review articles are welcome; authors interested in submitting a review article are encouraged to contact the editor in advance to discuss the scope. We invite all theoretician scientists and practitioners to submit their articles in order to share their knowledge in this area on the pages of this Special Issue of Energies. Topics of interest include, but are not limited to, models and methods:

  • Decarbonization of transport and logistics—system and process approaches;
  • Urban mobility aimed at decarbonizing the movement of people and loads;
  • Transport policy influencing the decarbonization of transport;
  • Strategies shaping the decarbonization of urban areas;
  • Cybermobility—tools and applications;
  • Zero-emission personal transport in the decarbonization of urban mobility;
  • Low-emission vehicles, electromobility, intelligent infrastructure, and ICT technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The effectiveness of railway brakes strongly depends on their thermal condition. A computer simulation and experimental investigations on a full-scale dynamometric stand were chosen as an adequate analysis of the heat transfer process in brakes. The article introduces a two-dimensional, axisymmetric numerical model of the tested disc brake. Boundary conditions related to the heat generated in the friction brake and heat transferred to the environment are also presented. The transient heat transfer problem was solved using the in-house computer program of the finite element method. The article presents simulations and experimental investigations of the intensive braking of a train with an initial high speed. Temperature responses of the disc brake on the friction surface and at other selected points are shown. In addition, a thermal imaging camera was used to assess the temperature distribution on the friction surface of the disc. The results of experimental and simulation tests were preliminarily compared. Similar maximum temperature values were obtained at the end of braking with a particular discrepancy in temperature responses during the analyzed process. Full article

This article concerns the identification of connections between the energy intensity of rail transport and spatial integration (convergence processes in the EU and spatial proximity) and the economic situation of countries that are in international export–import trade relations. Three research questions are formulated in the article: (1) Does the improvement of the economic situation of the importing country reduce the energy intensity of the Polish export of goods by rail transport to the partner country? (2) Does EU integration contribute to reducing the energy intensity of the export of goods by rail transport? (3) Is there a positive spatial effect (convergence) of reducing the energy intensity of the export of goods by rail transport? This study concerned 14 geographical destinations (export destinations from Poland) during the years 2010–2020. A comprehensive study of convergence was used by building a spatial (club) and type β convergence model and using an unconventional method (panel stationarity analysis). It has been verified that there is a convergence in the energy intensity of goods exportation by rail transport in EU countries. The rate of spatial (club) convergence is 8.66% per year, while the period after which this convergence will be halfway between the initial state and the long-term equilibrium point is 8 years.

An e-bike sharing system (e-BSS) solves many of the shortcomings of BSS but requires high financial investments compared to BSS. This article proposes a sustainable and targeted extension of the existing BSS with e-bikes and charging piles. The existing BSS in the selected city area is divided into sub-areas using the Voronoi diagram and reference points (landmarks). Then, the integrated approach of the Analytic Hierarchy Process (AHP) and Data Envelopment Analysis (DEA) is used to assess the adequacy of the existing bike-sharing stations for updating with e-bikes and charging piles. The joint approach allows decision-makers to look at the whole process and highlight the link between the criteria assessment and user preferences in the context of the chosen reference point. This can encourage future users to use e-BSSs. Based on a thorough literature review, the defined system of criteria takes into account all dimensions of sustainability: the requirements of most stakeholders and the structural features and needs of e-BSS. Finally, the super-efficiency DEA is used to classify the suitable candidates for bike-sharing so that only the most suitable stations are updated. The test of the proposed algorithm in Ljubljana city centre confirms several suitable options for updating the BSS, depending on the reference point. Full article
