Design of urban area using advanced technologies
Špaček, Jan ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
This thesis focuses on the design of urban areas in regards of the air flow and the creation of Urban Heat Islands. It reviews basic aspects influencing the design of streets. Every building, tree, or obstacle obstructs the air flow and creates the wind shadow, where the air pollution increases. It also creates areas of higher wind speed, in which public comfort is reduced. By understanding the importance of this process and by implementing it into the urban planning process, using advanced technology we can create healthy urban environment.

Spatial materials for additive manufacturing in civil engineering
Říha, Tomáš ; Apeltauer, Tomáš (referee) ; Podroužek, Jan (advisor)
The bachelor thesis deals with additive manufacturing in the construction industry and with materials used in this field. The first part of the thesis defines the 3D printing, briefly describes the history of this progressive technology and gives an overview of the used methods and technologies. The printing methods are divided according to the physical state of the basic material used for printing. The next part of the thesis presents the possible use of additive manufacturing in the construction industry and an overview of realized projects. Finally, at the end of the theoretical part are introduced materials applicable to additive manufacturing in the construction industry and is defined the concept of spatial materials. Spatial materials are a relatively new term, which is not yet in the literature sufficiently defined. These materials can be used for an application in a space where the structure and the position of their particles can be optimized. They can be applied for the creation of 2D filling structures, which are more useful for geometrically simple and simply loaded constructions. It is preferable to use spatial materials to create 3D structures that are designed to fill numerically optimized structures. These structures are based on the principle of double curvature and on a triply-periodic minimum surface (TPMS). In the practical part of the thesis was created the design of building block filled with 3D gyroid structure, designed for prefabrication by using additive manufacturing in the factory or at the site of construction. This proposal reflects the increasing demand for easy individualization of constructions and building elements. Especially, the demand for the creation of structures and shapes which are topologically optimized with a customized appearance and sufficient strength, all at the customer's request.

Traffic flow microsimulation in line management.
Mlčková, Ivana ; Apeltauer, Tomáš (referee) ; Apeltauer, Jiří (advisor)
The main task of this thesis is to verify the line management of traffic. A microsimulation model of traffic was made in program for traffic simulation called Aimsun. The data from radar measuring have been processed and then put into the model. Some of parameters in model were adapted to meet the reality on the road. Finally, there have been suggested more suggestions in this model and the efficiency of the solutions was evaluated.

Modeling the movement of people when organizing mass cultural events
Zelinka, Martin ; Apeltauer, Tomáš (referee) ; Okřinová, Petra (advisor)
The thesis deals with the movement of people in the event of mass events where a large number of people accumulate and thus the risks associated with problematic of so-called soft target. The study deals with the movement of people, taking into account the behavior of visitors, as well as the influence of individuals, couples or groups, as well as the possible movement of evacuated following a critical event. As the target of the analysis is the International Folklore Festival in Červený Kostelec. The aim of the work is to optimize the layout of the festival venue, adjacent areas and accompanying events in its surroundings so as to ensure maximum safety for the participants and eliminate crowd phenomena under different scenarios. The numerical model of the festival with the wider environment created by the Pathfinder software tool will serve as a basis for optimizing the solution.

Public space assessment using simulation of pedestrian movement
Forejtník, Ondřej ; Apeltauer, Tomáš (referee) ; Uhlík, Ondřej (advisor)
This bachelor's thesis deals in its theoretical part with the significance of the pedestrian traffic for the urban areas and describes the principles of numerical modeling of the pedestrian movement. In the practical part, the bachelor's thesis focuses on the assessment of the public space of náměstí Míru square in Brno using data extraction from a recorded video and numerical simulation of the pedestrian movement. This is followed by a verification of the traffic plan design in preparation and specific recommendations for amending the design. The aim of this work is to explore the contribution of modern technologies to the complex process of assessing and designing public spaces.

Simulation of the pedestrian evacuation from the school facility
Tesař, Martin ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The Bachelor thesis is focused on basic principles of soft targets security and on threats aimed at them. Part of this thesis is about the process of an evacuation movement modeling from a grammar school building, specifically the grammar school in Brno-Řečkovice. The model of the building has been created in the Revit program and the simulation of the movement in the Pathfinder program, which is based on agent simulation technologies. As for the methodology, the thesis is a comparison of the evacuation processes under different conditions.

Soft targets and crowded places protection using evacuation modeling
Dobiášová, Lucie ; Apeltauer, Tomáš (referee) ; Okřinová, Petra (advisor)
The thesis deals with the issue of protection of Prague's main train station as a soft target and it's regular operation, mainly by using evacuation model with emphasis on barrier-free issues. Mapping of the building was conducted by using Decree No. 398/2009 Coll. general technical requirements ensuring the barrier-free usage of buildings and their parts. Adapting the environment to people with reduced mobility is not always axiomatic, especially in terms of evacuation. For the movement of these persons it is necessary to take into account their needs and possibilities in normal traffic and during evacuation. The sociological and psychological aspects of crowd and individuals have also significant impact on evacuation. For identifying critical points of the main train station, it has been used knowledge of local research, knowledge of barrier-free buildings, sociology and psychology, and special simulation tools for modeling the movement of people. It has been found that space can be optimized by detailed analysis of simulation outputs to meet all expected requirements without negative impact on barrier-free domain. Thanks to this, it was possible to achieve a new design, which accomplishes higher safety of people with movement and orientation disabilities, especially during emergency situations in building of main train station Prague.

Calibration of the high-speed traffic microsimulation
Korček, Pavol ; Apeltauer, Tomáš (referee) ; Pospíchal, Jiří (referee) ; Sekanina, Lukáš (advisor)
Tato disertační práce je zaměřena na vysokorychlostní simulace dopravy a jejich přesnou kalibraci pomocí různých typů dopravních dat. Práce se po úvodním popisu motivace pro samotný výzkum nejdříve věnuje současnému stavu poznání, a dále rozdělení simulátorů dopravy, zejména podle typu dat, se kterými se v nich pracuje. Úpravou existujícího řešení je navržen vlastní mikrosimulační model, který je založen na principu celulárního automatu. S tímto novým modelem je pak experimentováno, zpočátku z pohledu rychlosti simulace a další rozšiřitelnosti. Je navržena a popsána technika, kterou je možné navržený model významně akcelerovat a následně provádět simulace rychleji než v reálném čase i pro rozsáhlá území. Práce dále přistupuje k samotné kalibraci modelu, ke které byl využit evoluční přístup. Je představena metoda pro efektivní způsob optimalizace parametrů mikrosimulačního modelu, která nevyžaduje citlivostní analýzu a je schopná nalézt jinak obtížně nastavitelné parametry modelu. Kvalita získaných optimalizovaných modelů byla analyzována jak pomocí makroskopických, tak i mikroskopických dopravních dat, a to i s ohledem na jejich reálné vlastnosti, tj. chybějící vzorky. Dále jsou zhodnoceny výkonnostní a jiné kvalitativní parametry vlastního přístupu v porovnání s existujícími řešeními, přičemž bylo dosaženo významného zlepšení. Nakonec jsou představeny nástroje, které v rámci řešení vznikly. Na závěr je uvedeno další zaměření výzkumu, a to zejména s ohledem na využití výsledků práce v praxi.
