Optimizing of road design elements by means of vehicles’ swept paths
Čepil, Jiří ; Katarína, Bačová (referee) ; Josef, Kocourek (referee) ; Radimský, Michal (advisor)
The dissertation deals with application of simulated swept paths of vehicles to road designs. Using software which generates simulated swept paths makes new demands on the designer, but Czech regulations do not stipulate the appropriate method of applying swept paths. The theoretical part of the dissertation analyses the theory of how a vehicle moves when passing through a horizontal road curve and a method of calculating a necessary extent of widening the road. The practical part compares swept paths generated by various software programs and differences between them. In order to verify the shapes and dimensions of the swept paths generated, the swept path of a real vehicle was measured. This swept path was then compared with the one generated, and the differences between them were evaluated. One of the software programs was chosen as a reference program, and its output was applied to a road design pursuant to valid regulations. The results obtained within the dissertation were used to develop certified methodology titled: „Methodology of widening road lanes in horizontal curves and of application of vehicles’ swept paths “.

Reconstruction of Roviny street
Tesáček, Svatopluk ; Smítal, Petr (referee) ; Holcner, Petr (advisor)
Within a range of study degree, the diploma thesis deals with a reconstruction design of three intersections and a single-span railway bridge along the Roviny street, Brno. The design is based on a familiarity with the territory as well as on traffic surveys. The proposed solution comprises the public transport lay-bys and pedestrians. The shape of intersections has been verified by means of vehicle-swept paths according to the TP 171 standard. The clearance under the bridge has been enlarged up to 4.80m and is in accordance with the S9.5 road category.

Vliv stavebně technického řešení komunikace na bezpečnost silničního provozu
Fasora, Radek
Fasora, R., Influence of building technical solutions of roads for the safety of these roads. Diploma thesis. Brno: Mendel University in Brno, 2014. Thesis describes the conditions of using the traffic roads. It is concered with towed curves for validation of driving through the curves. Precisely it is aiming to proposing and creating templates of the towed curves for tractor sets.
