Modification of crossing II/377 and III/37360 near Rájec Jestřebí
Bažant, Petr ; Coufalíková, Iva (referee) ; Holcner, Petr (advisor)
Adaptation of level crossing of road II/377 and III/37360 near Rájec-Jestřebí in the South Moravian region is solved in bachelor´s thesis. The level crossing is a special cover crossing in the shape of the letter K with two-lane rous, not directionally dividend. The major road consists II/377, secondary III/37360 and local road leads to village Holešín ( part of the town Rájec-Jestřěbí ). It is not a place with many travel accidents, that was affirmed by Czech Republic police, but it is a crossing with very confused arrangement and directions of the main and secondary rouds and mainly insufficient vertical arrangement. The outputs of road traffic survey made of the purpose of the thesis, examination of outlooks and the proposal improvement of clarity with the construction the eliptic roundabout.

Analysis of reinforced concrete bridge in Velké Meziříčí
Necid, Miloš ; Koláček, Jan (referee) ; Zich, Miloš (advisor)
I deal with the road bridge in Velké Meziříčí in the thesis. The bridge is a reinforced concrete structure with one field, with two main beams above the ground level. In the first phase I assess existing state of the ultimate limit state. I do calculation of internal forces both manually and in Scia Engineer. Furthermore, I propose two possible solutions of measures for the main beams to increase the carrying capacity and improving sight conditions on the bridge. In both variants I prestress the main beams with prestressing reinforcement. In the last option I propose a new bridge supporting structure, which is an additional prestressed slab.

Safety and fluency increasing - road I/43 Černá Hora - Sebranice
Bažant, Petr ; Tesař, Jiří (referee) ; Všetečka, Martin (advisor)
A part of the road I/43 in the section between Černá Hora and Sebranice is the subject of diploma thesis. The output of thesis is to identify problematic parts of the safety and fluency of traffic and to propose appropriate measures. The road I/43 is very problematic and discussed of these aspects. Becouse of the character and the results of traffic accidents is called Highway of death. The thesis contains proposals of structural modification in selected problematic sections. These structural modifications are intended to increase the safety of traffic, but in order to limit of flow of traffic. Depending on the long-delayed contruction of expressway R43 is in order to make quick and effective increase the safety and the fluency of traffic counting with traffic intensity in the full range.

Crossroad I/2 and street Školní in Pardubice - Study
Hauk, Martin ; Matuszková, Radka (referee) ; Radimský, Michal (advisor)
The subject of the bachelor's thesis is a study of the modification of the existing intersection of road I / 2 and Školní Street located in the western part of Pardubice. It is a T-intersection in the urban area. The problem at a given intersection is high traffic. This thesis deals with solving this problem by increasing the capacity of the intersection to facilitate the exit from Školní Street, and ensuring better safety, because there have been countless accidents in the past. The result of the thesis is the design of three variants of the modification solution and then selected one variant that best solves the increase of capacity and safety of the intersection.

Possibilities of Point Cloud and Mesh Model Creation of Accident Site Using Photographs
Mojžyšek, Tomáš ; Bradáč, Albert (referee) ; Křižák, Michal (advisor)
The thesis focuses on creating point cloud and mesh model of chosen intersections and their applications in forensic-engineering praxis. In the first part, we describe a workflow for creating point cloud and mesh model of intersection by digital photogrammetry. In the second part, we applied these at chosen intersections. Which leads us to the comparison of three digital photogrammetric programs which we used to make point clouds and mesh models. At the end of thesis, we use our mesh models in forensic-engineering praxis and we decide about barriers in sign conditions at intersections.

Analysis of Critical Places of Road and Railway Transport Intersections in the Southmoravian Region
Chlup, Daniel ; Ptáček, Petr (referee) ; Libertín, Josef (advisor)
Point of this diploma thesis is analyzing of three railroad crossing controlled by institutions of South-Moravian region, which are chosen by author. For analysis were chosen problematic railroad crossing where happened in last five years traffic accidents with consequences of death. Next criterion of choosing was type of security device. Chosen railroads crossing are representing all types of normally used security devices. That is why was chose railroad crossing with only warning crosses, light security device and last one with light security device with barrier beam. Theoretical part aims on: Basic parameters, dividing, numbering, system of function and marking of railroad crossing. In practical part, there are used mathematical calculations for assessment of safety on chosen railroad crossing and for determination of possibilities of averting a collision of both participants. Corrective measures are made for each railroad crossing taking to account it’s financial conditions. For each railroad crossing is made polygon with help of program Virtual Crash 3.

Crossroad I/36, II/211, III/32225 and road to the Synthesia complex in Pardubice - Study
Kolář, Dominik ; Hornýš, Michal (referee) ; Radimský, Michal (advisor)
The subject of this diploma thesis is a study of an crossroad adjustment of roads I/36, II/211, III/32225 and tertiary road, which connects industrial area SemtinZone to the crossroad. Tho crossroad s located in the Rybitví municipality, northwest of the Pardubice. There is currently an crossroad with an inappropriate crossing angle. This thesis includes traffic survey, the assesment of the rate of accidents, the design of three different variants of the crossroad, including sight triangles and turning radius check. Then assessment of capacity for forecasted traffic volume of each variant. By a multi-criteria evaluation the optimal variant was chosen.
