Reconstruction III/00222 between road II/425 and Ladná
Navrátilová, Pavlína ; Loučka, Miroslav (referee) ; Matuszková, Radka (advisor)
The subject of this work is the proposal of reconstruction of the existing road III / 00222 according to the amended ČSN 73 6101. This reconstruction is limited in space. The study includes the design of new design elements and the design of a new bridge structure under which the railway tracks are located. The content of the thesis is a complete reconstruction of the road and the design of the bridge structure.

Analysis of roundabout design parameters and their impact on accidents.
Novák, Jan ; Karpíšek,, Zdeněk (referee) ; Mahdalová,, Ivana (referee) ; Macur, Jiří (referee) ; Holcner, Petr (advisor)
The dissertation deals with the analysis of roundabout design elements and their impact on accidents. The analysis objective was to identify the important elements of roundabouts that have impact on accidents. In order to achieve this goal, the multifactorial statistical safety assessment method was used on the basis of a representative sample of data, by developing several safety performance functions, verifying them and interpreting the result. Several design elements, which from the point of view of the traffic accident mechanism belong to the infrastructure factor, have been identified: AADT, average diameter, entrance width, entry angle, direct passage angle, location and many others. The original sample contained about 1200 roundabouts, which were reduced to 200 based on data availability. Accident frequencies were monitored between 2009 and 2016, i.e. for eight years, resulting in total 2674 roundabouts accidents. The result is an accident prediction model, developer based on roundabout approach design elements, and map of critical roundabouts, identified based on empirical Bayes estimate of accident frequency. Following approach parameters were identified: AADT, entry angle, distance between collision points, deviation of angles between approaches, presence of apron, presence of bypass, entry type, presence of pedestrian crossing and surrounding area type.

Vyškov - north bypass
Greguš, Jakub ; Hruban, Tomáš (referee) ; Radimský, Michal (advisor)
The subject of this diploma thesis is the development of a prospective study of the northern bypass of the village of Vyškova, between roads II/431 and III/37728, with regard to the connection of all existing roads, the reconstruction of railway No. 260 Brno – Přerov and the planned development of the sports area of the village of Vyškov.
