Selected ČSN Road Design Elements Optimization
Stránský, Jakub ; Čepil, Jiří (referee) ; Kosňovský, Michal (advisor)
The master‘s thesis focuses on the optimization of the design values of curves of the horizontal alignments of the roads. It deals with the comparison of values between czech and foreign standards and differences between them. The practical part examines the values of the real speeds of vehicles passing through the curves of various parameters that were measured during measurements of selected curves during 2014. From these data a new design values are derived that could be used for the design of horizontal alignments.

Methods for estimation of extreme precipitation and their applications in the Czech Republic
Picek, J. ; Kyselý, Jan ; Gaál, Ladislav
The paper summarizes concepts and methods applied in estimation of probabilities of extreme precipitation amounts and design precipitation in the Czech Republic in the recent past. This work was motivated by the occurrence of several extraordinary precipitation events that resulted in floods with enormous material damages, but also by advances in the field of statistical modelling of extremes. The methods that we introduce are split in two main parts: methods for estimation of probable maximum precipitation and methods for estimation of design precipitation using different variants of the regional frequency analysis. In the concluding section several open issues and possible directions of follow-up research and improvements are outlined.
