Since the Depression era there has been an evolution in parkway usage. Parkways have outlived their recreational function and now must also serve as routes to recreational facilities. Since the elemental use of parkways has drastically changed, questions of how and why beg to be answered. How has parkway design and construction changed from the Depression era to today in terms of views, alignment, vegetation, natural and cultural features, and parkway details. How is parkway design and construction different from that of typical roadways; and how does this information effect the future design and construction of parkways? In addition, why can parkways no longer serve the same purpose that they did in the past? This thesis examines these questions through the creation of the Lorton - Laurel Hill Parkway. The main characteristics studied in this thesis will continue to be vital in future parkway design and construction. This thesis expresses that parkways can no longer serve as a destination, but instead must become an introduction to a recreational facility. Parkways will become increasingly important in the future as they can provide relief to congested roadways while simultaneously providing the motorist with an aesthetically pleasing entrance to recreational facilities. In the future, the components studied here must be instituted into highway and road engineering. The construction of motorways that incorporate parkway design principles will create more successful and vibrant routes between urban centers and their surrounding communities, and in so doing will increase the quality of life of its population. / Master of Landscape Architecture

O estudo de traÃado para obras lineares apresenta-se como um tema de suma importÃncia nas fases de concepÃÃo e definiÃÃo das diretrizes a serem estudadas para elaboraÃÃo de projetos de infraestrutura de transportes. A definiÃÃo do traÃado de uma via deve ser feita observando o resultado do estudo das alternativas de traÃado e a comparaÃÃo entre elas, matematicamente existem infinitas possibilidades de alternativas de traÃado entre pontos sucessivos o que dificulta a escolha de uma Ãnica soluÃÃo. A dificuldade em se definir critÃrios e parÃmetros objetivos para determinaÃÃo de uma Ãrea de estudo e consequentemente a melhor alternativa de traÃado motivou o estudo apresentado. As anÃlises de traÃado atuais se limitam a diretrizes prÃ-estabelecidas em um nÃmero reduzido, o que pode induzir a escolhas de traÃados que conduzam a custos mais elevados e Ãs condiÃÃes de operaÃÃo e manutenÃÃo indesejadas para a futura via. PropÃe-se um mÃtodo de definiÃÃo da melhor faixa para estudo de traÃado para obras de infraestrutura de transporte tomando como base dados topogrÃficos, considerando custos de implantaÃÃo e de operaÃÃo. O mÃtodo sugerido consiste na varredura tridimensional da regiÃo onde se insere a obra em estudo, apontando as melhores faixas para desenvolvimento do projeto baseando-se na topografia, considerando caracterÃsticas geomÃtricas do projeto, Ãreas de restriÃÃo, custos de implantaÃÃo e de operaÃÃo. O mÃtodo de seleÃÃo proposto foi aplicado em uma variante ferroviÃria de oito quilÃmetros, onde foram analisadas 729 alternativas e definida a melhor faixa para o estudo de traÃado. Os resultados foram comparados ao projeto executivo e feitas as mesmas consideraÃÃes utilizadas no projeto o que demonstraram a viabilidade da metodologia. / The study of horizontal alignment for linear works presented is an issue of paramount importance in the design and definition of the guidelines to be studied for the preparation of transport infrastructure projects. Setting the tracing of a track must be made observing the result of the study of alignment alternatives and comparing them, mathematically there is infinite possibilities for alignment alternatives between successive points making it difficult to choose a single solution. The difficulty in defining criteria and objective parameters for determining an area of study and therefore the best alternative route led the study presented. The current trace analysis is limited to pre-set guidelines on a limited number, which can induce choices paths leading unwanted higher costs and operating and maintenance conditions for future route. It is proposed a better range setting method for the study of horizontal alignment for transport infrastructure projects based on topographic data considering deploying and operating costs. The suggested method is the three-dimensional scan of the region which includes the work under study, pointing out the best tracks for development based on the topography design, considering geometric characteristics of the project, restriction areas, deployment and operating costs. The proposed selection method was applied in a railway variant of eight kilometers, where 729 alternatives were analyzed and then set the best track for the study of horizontal alignment. The results were compared to the executive project and the same considerations used in the project were made which demonstrated the feasibility of the methodology.

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.

The diploma thesis is focused on insufficient capacity problem of roundabout I/35, I/57 and II/150 in the Valašské Meziříčí town. It is based on engineering survey according to which three possible models are designed. Capacity assesment is made on each of these models. Throug the evaluation is selected the most suitable design of turbo roundabout type "knee", which is technically processed and substantiated by text and drawing documentation.

The aim of my master´s thesis is to design documentation, at the level of study, for roundabout. The area of interest is defined by the crossroad of Lounská, Americká, Bílinská streets and the conection of existing road I/13 . This is the crossroad of local roads, which are functional group C-serving with the serving function. The aim of conversion of existing crossroad on the roundabout is to calm and clarify the traffic in the locality. There are also designed comunications for pedestrians in the locality. The study is solved in two variant of conection to existing road I/13.

The subject of this masters thesis is preliminary design of III. phase connector road of D7 and D8 motorways near Kralupy nad Vltavou. The reason for this highway design is high traffic intensity. The highway is designed as a road type S9,5/90. Highway design includes two junctions. Junctions are designed in two variants, only one variant of each junction was finalized to more in-depth detail.

Aim of this Master´s thesis is the road adjustment and design of new grade separated junction highway R43 and road I/43,of Černá Hora – Svitávka and to design optimal distribution of transport hubs including the design II/150 and III/37429, which should be connected with existing roads.The adjustment of the routes will be designed in the necessary extent with the optimal distribution of transport hubs regarding the best transport and economical solution and with minimal impact on the enviroment.
