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.
Traffic Organizing of Svatoplukova Street in Brno
Bátora, Filip ; Havlíček, Antonín (referee) ; Všetečka, Martin (advisor)
The main goal of my diploma thesis is the design of transport-engineering measures on the Svatoplukova street with the focus on the finalization of the Great Brno ring road and the following changes of traffic intensity. For the implementation and simulation of my designed measures, I used the PTV Vissim modeling software. The simulation outputs were then evaluated and transformed into recommendations to be taken into consideration during the creation of future traffic-engineering measures in the given area.
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.
Verification of the urban design of Mendlovo náměstí from the point of traffic
Zelinka, Petr ; Všetečka, Martin (referee) ; Apeltauer, Jiří (advisor)
The diploma thesis deals with the modeling of traffic in the Mendel Square according to the documents of the Office of the Brno Architect. The modeling process takes place in software Aimsun. The result of this work is to compare the data with the provided results according to the standard, to determine the resulting output values from the software and to identify the problem areas affecting individual transport and urban public transport.
Microscopic Simulation of the junction Malá Amerika
Horák, Michal ; Mikolášek, Igor (referee) ; Všetečka, Martin (advisor)
This bachelor thesis deals with the modeling of traffic flow in several variants of the transport network. Variants are modeled in Aimsun. Current status data was obtained by field observation. In the created models, the traffic flow of both current and future traffic intensities is simulated. Based on the outputs of the simulated operation, the variants are assessed. The proposed variants are compared and the most suitable arrangement chosen.
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.
Microscopic traffic modelling in urban areas
Brožek, Jan ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The bachelor thesis deals with a traffic modeling from theoretical and practical per-spectives. Microscopic traffic models for various circumstances were created in the Aimsun software and then they were compared with each other.
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.
Economic Evaluation of Transport Situation
Doležel, Robin ; Matuszková, Radka (referee) ; Korytárová, Jana (advisor)
The diploma thesis deals with modeling and subsequent economic assessment of the traffic situation of a particular intersection, applying the rule of right turn on red light signal. The thesis is divided into a theoretical part, which describes the rule, the general procedure of creating transport microsimulation and the methodology of the evaluation of economic efficiency according to ŘSD. In practical part the interest area is described and microsimulation of existing and design variants was created in Aimsun. The Aimsun outputs are further compared and economically evaluated.
Microscopic simulation of intersection of roads I/41 a 1/42
Kaňok, Vojtěch ; Novák, Martin (referee) ; Všetečka, Martin (advisor)
The bachelor thesis deals with modelling and comparing traffic arrangements, using microsimulation traffic flow modelling. The traffic dates were processed by Aimsun. Several design variations were created. These were compared with each other and the most effective arrangement was recommended afterwards.
