The subject of Master’s thesis is the variant redevelopment of cover crossroad, which is part of over-level junction of roads I/52 and II/152 near the village Želešice. The existing junctions are unsatisfactory in terms of capacity and long queues arise. The thesis contains a proposal of 3 variants, which are looking for different solutions to increase the capacityy of level crossings. Part of the thesis is a traffic survey, determination of traffic intensity, capacity analysis of current state and designed variants.

My thesis is about intersection which is very dangerous, because there is´t lighting so intersection is unclear and drivers don´t to abide speed limit. There are serious accidents so I had to modify it. I designed three versions: First with concrete barriers, second is in trims and last one is spiral roundabout. Last version is more refined. Every version is with LED lighting in all area.

This thesis addresses the traffic situation in the city of Velka Bites delay in the street Pod Hradbami. The proposed solution includes an adjustment of adjacent intersections. They are designed with two roundabouts together with a directional adjustment of individual strings attached communications. The draft has parking lot. Drawings are made in the range of documentation for building permit.

The theme of this master thesis is a way of solving tram track elongation in Brno - Lesna. The task was to draw up a tram track through the crossroad of streets Merhautova, Seifertova and Okruzni including reconstruction of crossroad. This master thesis deals with the of different variants of solution of crossroad. The most appropriate option is worked out further. In this work is also included outlining of futher tram tracking behind the crossroad and placement of the nearest tram stops. The result of this work is to elaborate of the situation including charasteristic cut sections and longitudinal profiles of tram lines. Part of this work is an estimate of the financial cost to realize this building.

This master’s thesis deals with drawing Winter change to replace an existing capacity-inconvenient crossroad. This crossroad is located near by city Kuřim and it has free branchs – II/386 connecting on theroad I/43.Thisinterchangesolvesconnectionfromthaplanned bypass of the city Kuřim. This by-pass road will connect to road R43. An precondition preservativ of the existing road I/43 in the current position to get drawing of the innterchasecheaper. Intersection is designed to enable branching in all directions crossing.

This thesis describes the concept of transport solution with the help of microsimulation. Using intensities obtained from the landscape is a simulation of the current status and new proposals. They are compared using a detention time. For the winning option will be implemented spatial study.

The aim of this Master's thesis is design of possible modifications of crossroad I/55 and II/432, primarily with focus on capacity and safety. The first part of this thesis is dealing with measurement and evaluation of current traffic intensities, and capacity calculations of suggested design modifications. The second part of the thesis consists of detailed project of one design modification (diamond interchange) for documentation for construction permit.

The aim of this thesis is to design a roundabout in front of the main entrance to the Exhibition in Brno on the crossing of streets Veletržní, Křížkovského and the entrance to the trade fair. The thesis take into account the reconstruction of Mendel Square, which is invited to solve a two-way street Veletržní. The entrance to the BVV has made available two-storey underground garage. The project also deals with the relocation of the existing bus stop Křížkovského.

Eine realistische Simulation von Verkehrsabläufen kann einen wichtigen Beitrag zur Verkehrsplanung leisten. In dieser Arbeit wird dafür in den bestehenden mikroskopischen Simulator MovSim ein Kreisverkehr implementiert. Anschließende Analysen, die unter Verwendung des Intelligent-Driver-Modells und des Spurwechselmodells MOBIL durchgeführt wurden, legen nahe, dass die relativen Ergebnisse, die sich durch Veränderung des Verkehrsflusses und der Modellparameter ergeben, realitätsnah sind. Zudem konnte gezeigt werden, dass der Einfluss des Verkehrsstromes in der Kreisfahrbahn im Handbuch für die Bemessung von Straßenverkehrsanlagen deutlich stärker ist als in der Simulation.

ABSTRACT Purpose: The purpose of this study is to analyze the different contract changes that potentially could be added to projects made on the road. For this study specifically, a project where a traffic circle is produced, is used as a reference. This is then further investigated by how these contract changes occurred and what type of temporal, economical and technical influence each and every contract change has on the project. By knowing why and how these contract changes occur, there is an evaluation made to list the different factors that entail the contract changes and different methods to prevent these factors which results in less appearing contract changes. Methods: The methods used in this study contains literature studies and case studies as well as analyzing documents regarding the project, calculations made and measurement values and lastly interviews with the different members that are involved in this project. Results: The results gave a perspective of what types of contract changes the project had and how each one affected the project temporally, economically and technically. The results also included answers from the entrepreneur, the client and the consultant for the interviews. It gave a perspective of their view on the project and their thoughts on the contract changes. By compiling their opinions and views one could detect the similarities and the differences. Further after gathering all of the previous results and comparing them, one could identify a common denominator where there clearly is a mismanagement and find ways to fix and evade the problems which results in less contract changes arising. Conclusion: All of the contract changes has been summurized and conlcuded in a UR-sheet. The following conclusions could be drawn from the framing of questions and results: there were a total of 18 different contract changes where as two of these were regulated from outsider factors. The rest were regulated through factors within the project itself, meaning they could have been either prevented or some what predicted and could have had a less of a effect on the project. All of the contract changes had some type of technical effect on the project however not all of them had an effect temporally or economically. The one that had most effect was UR_ÄTA_006 where this was regulated because of a previous project that wasn’t completed in time and stood as a hindrance for the roundabout. This contributed in extra charges, more time spent of certain moments and changes in the timetable. Based on the answers from the interviews, one could conclude that all of the people who are involved in the project think that there are some deficient working power in the project planning. As a solution to the issue, they sugested that one of the people from the entreprenuer side and the client should be some what involved in the early stages and work as a helping hand for the project planning side of the project since they have more experience in how the actual production of a project is done, thus resulting in less contract changes.  Keywords: Contract changes, roundabout, entreprenouer, client, consultant, temporal, economical, technical,, documents / Oftast inte
