1. Spatial modelling of modal shift due to COVID-19Simona Šinko, Klemen Prah, Tomaž Kramberger, 2021, izvirni znanstveni članek Opis: The outbreak of COVID-19 caused many changes in people's life. One of the most significant is the travel behaviour and transport mode choice. This study focus on the changes that the inhabitants of Vienna made in their travel choices because of the virus. The same research about spatial modelling the transport mode choice of commuters in Vienna was completed in 2019 and is a topic addressed in our previous work. Based on our developed methodology, this article indicates that public transport is not a dominant transport mode choice as it was before the virus outbreak.The main result of this paper is geographically defined areas of application of individual alternatives shown on the final map of modal shift in Vienna, which could provide theoretical support for policy-makers and transportation planners. For the city of Vienna, we found that the area of the city where cars are now used has increased, which certainly has a negative impact on air quality and life in the city. The advantage of the methodology is that it can also be applied to other cities in the world.

2. Traffic density-related black carbon distribution : impact of wind in a basin townBorut Jereb, Brigita Gajšek, Gregor Šipek, Špela Kovše, Matevž Obrecht, 2021, izvirni znanstveni članek Opis: Black carbon is one of the riskiest particle matter pollutants that is harmful to human health. Although it has been increasingly investigated, factors that depend on black carbon distribution and concentration are still insufficiently researched. Variables, such as traffic density, wind speeds, and ground levels can lead to substantial variations of black carbon concentrations and potential exposure, which is even riskier for people living in less-airy sites. Therefore, this paper "fills the gaps" by studying black carbon distribution variations, concentrations, and oscillations, with special emphasis on traffic density and road segments, at multiple locations, in a small city located in a basin, with frequent temperature inversions and infrequent low wind speeds. As wind speed has a significant impact on black carbon concentration trends, it is critical to present how low wind speeds influence black carbon dispersion in a basin city, and how black carbon is dependent on traffic density. Our results revealed that when the wind reached speeds of 1 ms-1 , black carbon concentrations actually increased. In lengthy wind periods, when wind speeds reached 2 or 3 ms-1 , black carbon concentrations decreased during rush hour and in the time of severe winter biomass burning. By observing the results, it could be concluded that black carbon persists longer in higher altitudes than near ground level. Black carbon concentration oscillations were also seen as more pronounced on main roads with higher traffic density. The more the traffic decreases and becomes steady, the more black carbon concentrations oscillate.

4. Smart city solutions in regard to urbanization processes : Polish casesHalina Brdulak, Anna Brdulak, 2015, izvirni znanstveni članek Opis: The aim of this paper is to show the spectrum of problems associated with the growing importance of cities in the context of rapidly occurring processes of urbanization. Therefore the following issues are included: the concept of smart cities, which are a combination of the intelligent use of information systems allowing for active management of the various areas of urban activity with the potential of institutions, companies and the active involvement and creative people; transport problems and the use of new technologies. Particular attention will be given to both, the issue of transport congestion as the strongest factor affecting the quality of life of residents and to the role of social capital in the creation of sustainable development. To exemplify the result of the cooperation between southern Polish communities there will be presented a case of the introducing process of the Silesian Card of Public Services with a wide range of its functionality.

5. Supplying restaurants in a closed city centre with sustainable transport methodsMatic Gole, 2013, diplomsko delo Opis: Supply of goods in the city centres can be quite a task, especially if we want that it's based on a lot of modern technologies and point of view's, such as environment, safety regulations and so on. In our thesis, we went through the theoretical part, which was the basis for the solution for supplying city centre of Ljubljana.
We discovered that Ljubljana has a lot of vehicles entering a pedestrian area, so we made a proposition of investment into a sustainable transport methods such as electrical or solar driven vehicles. If we include a good timetable into the equation, this means that from this, all stakeholders can benefit and there can be substantial improvements from all mentioned point of view's.

6. Modeling of city logisticsSabrina Trafela, 2013, magistrsko delo Opis: Master thesis has it's fundamentals in the use of theoretical methods for modeling purposes on the case study of city logistics and modeling of traffic flow and transportation problem on the city of Győr, Hungary.
In practical part, we made a measurements of traffic flow on street sections in the city of Győr. With Android application, we gathered necessary data. We also prepared maps of the route sections of the city from various entry points to the final, destination point. Purpose of our thesis was finding the optimal solution for the delivery to the city centre with the use of strategic games.
Final step was a preparation of mathematical model in Mathematica programming environment, which gave us results, but most important is the development of the model itself. Model is constructed in a way that can be use in various possible situations and on different city centres or case studies.
