Methodology for estimating the effect of traffic flow management on fuel consumption and CO2 production : a case study of Celje, Slovenia
Borut Jereb, Ondrej Stopka, Tomáš Skrúcaný, 2021, izvirni znanstveni članek

Opis: The manuscript discusses the investigation of vehicle flow in a predesignated junction byan appropriate traffic flow management with an effort to minimize fuel consumption, the productionof CO2, an essential greenhouse gas (hereinafter referred to as GHG), and related transport costs.The particular research study was undertaken in a frequented junction in the city of Celje, located in the eastern part of Slovenia. The results obtained summarize data on consumed fuel and produced CO2 amounts depending on the type of vehicle, traffic flow mixture, traffic light signal plan, andactual vehicle velocity. These values were calculated separately for three different conditions of traffic flow management. Amounts of fuel consumed were experimentally investigated in real traffic situations, whereas CO2 production was calculated by applying the actual European standardentitled EN 16258:2012 associated with a guideline for measuring emission values, as well as by examining specific traffic flow parameters. The key objective of the manuscript is to present multiple scenarios towards striving to minimize environmental impacts and improve transport operation's economic consequences when implementing proper traffic flow management. As for crucial findings, we quantified fuel consumption and CO2 emissions based on real data on the number and type of vehicles crossing the examined intersection and traffic light switching intervals. The results show that most of the CO2 was produced while waiting and in the accelerating phase in front of traffic lights, whereby in the running phase through the intersection, significantly less fuel was used. This study represents a mosaic fragment of research addressing endeavors to reduce CO2 production in urban transport. Following the experiments conducted, we can see a notable contribution towards reducing CO2 production with known and tested interventions in the existing transport infrastructure. A procedure embracing individual research steps may be deemed as an approach methodology dealing with traffic flow management with an aim to decrease the environmental and economic impacts oftraffic and transport operation; this is where the novelty of the research lies.

Real capacity of ropeway transportation subsystem
Drago Sever, 2000, drugi znanstveni članki

Opis: The ropeway transportation system plays a major role in mountain resorts. In order to provide a sustainable development of the entire mountain resort system, the real capacity of the ropeway transportation system was set. The real capacity of the ropeway transportation system is one of the indicators of the development harmonisation level of single system elements. The research into this field was carried out at the Road Traffic Centre of the Faculty of Civil Engineering, University of Maribor. The paper deals with the basic points of the topic and the methods used. The know-how transfer of experiences into the Slovenian environment is presented together with the obtained results.

Railway traffic management as a function of the new infrastructure manager
Damjan Mlakar, Drago Sever, 2007, pregledni znanstveni članek

Opis: This article offers a survey of the current decentralised form of railway traffic management within the public railway infrastructure in the The Republic of Slovenia, which is the result of out-of-date and worn-out safety installations of railway stations and railway lines. The article presents a new model of railway traffic management as the basis for efficient activity and harmonization of railway traffic management in the The Republic of Slovenia to the systems of railway traffic management within EU. This article presents the advantages of a centralised system of railway traffic management and demonstrates that the application of this system can solve the problem of decentralized traffic management as a function of the new infrastructure manager.
Ključne besede: traffic management, centralization of railway traffic, traffic management centre, railway traffic management model

Encyclopedia of complexity and systems science
slovar, enciklopedija, leksikon, priročnik, atlas, zemljevid

Opis: Encyclopedia of Complexity and Systems Science provides an authoritative single source for understanding and applying the concepts of complexity theory together with the tools and measures for analyzing complex systems in all fields of science and engineering. The science and tools of complexity and systems science include theories of self-organization, complex systems, synergetics, dynamical systems, turbulence, catastrophes, instabilities, nonlinearity, stochastic processes, chaos, neural networks, cellular automata, adaptive systems, and genetic algorithms. Examples of near-term problems and major unknowns that can be approached through complexity and systems science include: The structure, history and future of the universe; the biological basis of consciousness; the integration of genomics, proteomics and bioinformatics as systems biology; human longevity limits; the limits of computing; sustainability of life on earth; predictability, dynamics and extent of earthquakes, hurricanes, tsunamis, and other natural disasters; the dynamics of turbulent flows; lasers or fluids in physics, microprocessor design; macromolecular assembly in chemistry and biophysics; brain functions in cognitive neuroscience; climate change; ecosystem management; traffic management; and business cycles. All these seemingly quite different kinds of structure formation have a number of important features and underlying structures in common. These deep structural similarities can be exploited to transfer analytical methods and understanding from one field to another. This unique work will extend the influence of complexity and system science to a much wider audience than has been possible to date.
