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.

Traffic engineering design of Přímá-Nábřeží intersection in Zlin
Hájková, Barbora ; Dorňák, David (referee) ; Smělý, Martin (advisor)
The master’s thesis deals with a solution of a complicated traffic situation on the Přímá – Nábřeží intersection in Zlin. The first part of the thesis focuses on the diagnostic of the current state of the junction. In the second part, the author compares possible solutions, traffic light control is chosen as the best. Traffic light plans are designed and coordinated with a nearby traffic light controlled intersection Tomáše Bati – Přímá. It the last part, the solution is verified and represented by a microsimulation.

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.

Microscopic traffic model of streets Veveří and Kounicova.
Válková, Michaela ; Všetečka, Martin (referee) ; Apeltauer, Jiří (advisor)
Diploma thesis deals with microscopic traffic model of the streets Veveří and Kounicova including adjacent road network. This model was created in software Aimsun based on maps, the results of the directional survey, traffic intensity at junctions and signal plans. Elaborated model of the current state location of interest was calibrated according to the traffic intensities on the entrance and exit roads. They have also been designed and created three possible variants of the solution streets Veveří and Kounicova. All variants were finally compared and evaluated.

2 + 1 Roads
Kosňovský, Michal ; Apeltauer, Tomáš (referee) ; Kocourek,, Jiří (referee) ; Radimský, Michal (advisor)
This dissertation addresses the possibility of using the 2+1 road arrangement in the Czech Republic. Given that there is no such 2+1 segment in the Czech Republic, it was necessary to find sections with similar characteristics, evaluate and measure the rate of accidents as well as sectional velocity. The accident rate was evaluated on 72 sections and based on this research the optimal length of 2+1 arrangement road sections was determined. Digital image analysis and license plate recognition was used to evaluate the sectional velocity. Eight selected sections was subjected to the additional sectional velocity measurement, which showed improvement in passenger vehicles travel time. Traffic model microsimulations were performed after the data analysis. 2+1 arrangement roads are suitable solution for increasing travel speeds on sections where building of four-lane road is not economically viable.

Microscopic traffic simulation in urban areas
Bátora, Filip ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The main goal of my bachelor's thesis is to provide a theoretical insight on the topic of traffic modelling, as well as finding a practical solution to a specified issue. I will use the Aimsun software to create a microscopic model of a traffic junction using two different modes of traffic light signals. With the help of various methodical directions, I will provide an economical evaluation and comparation of the overall junction travel time.

Lipůvka – turbo roundabout of roads I/43 and II/379
Patočka, Miroslav ; Sedlák, Lubomír (referee) ; Smělý, Martin (advisor)
This thesis builds on previous work on an Institute of Roads FAST VUT dealing with modifications of road I/43 Brno – Svitavy. A conversion of the existing temporary three leg single lane roundabout to egg turbo roundabout with four legs, is proposed there, in accordance with local plan of Lipůvka. The intersection of road I/43 and II/379 can be characterized by large congestions in the morning peak hours during weekdays and afternoon peak hours on Saturday and Sunday. That is the reason for implementation of capacity assessment of designed turbo roundabout and comparison with current situation. Construction of fourth leg is motivated by the planned expansion of residential area and the development of industrial zone on the south-western outskirts of the village and rerouting of the county road II/379 out of built-up area as well. Road I/43 is an important thoroughfare north of Brno, so it is obvious effort to eliminate the bottlenecks on the route. The thesis also includes a theoretical introduction dealing with the design of turbo roundabouts abroad.

Traffic Organizing of Žarošická a Jedovnická Streets in Brno
Výstup, Jan ; Havlíček, Antonín (referee) ; Všetečka, Martin (advisor)
This thesis deals with the impact of future traffic load on the level of traffic quality in Rokytova, Žarošická and Jedovnická streets after the opening of parts of the large urban ring road Tomkovo náměstí, Rokytova and Ostravská radiála. To assess these impacts, a microscopic traffic model is used, which is created in the Aimsun software using map data, directional survey at the affected intersections, traffic volumes and observed signal plans. The next part is the traffic engineering design of Žarošická and Jedovnická streets in several variants including their assessment.
