"Over the years, risk analysis methodologies have been developed and implemented by many industries. NASA has implemented a cost efficient Continuous Risk Analysis methodology with good results. The U. S. Department of Transportation also states that a continuous risk analysis is the key in identifying, addressing, and handling risks before they become threats to success. However, current practices seldom incorporate this concept into real transportation projects. In general, risk is simply disregarded in feasibility studies. One of primary reasons is the lack of a feasible and effective risk analysis approach to guide efficient implementation in real projects. This thesis reviews current risk analysis practices used in public transportation projects. Using a case study, it also explores potential obstacles encountered in the implementation of systematic risk analysis. Finally, this thesis presents a preliminary risk analysis framework developed through the case study and enriched subsequently by incorporating material documented in the literature. The proposed risk analysis approach is to help achieve continuous risk analysis in transportation projects by enabling early start, frequent implementation, extensive application and flexible adoption."

As cidades superaram o campo. Motivo de celebração, afinal as cidades são e continuam sendo a expressão mais complexa da humanidade. Nunca acabadas, nunca definitivas, as cidades são a manifestação física de história e cultura, centros de crescimento econômico, inovação e talento. No entanto, o que se vê é um crescimento desenfreado de assentamentos precários e aumento da pobreza urbana. Como irão viver os mais de um bilhão de residentes urbanos estimados para os próximos 15 anos? É a crença deste trabalho que as infra-estruturas urbanas têm papel fundamental na regulação e no desenho do território, já que criam novas oportunidades de desenvolvimento urbano e interferem diretamente no ambiente construído e natural. / Cities have outgrown the coutryside. This could be celebrated, since cities were and still are mankinds richest expression. Never finished, never definitive, cities present history and culture in their most physical aspects, true centers of economic growth, innovation and talent. Sadly, what we see in our cities is an uncontrolled growth of precarious settlements and the increase of urban poverty. How will an estimated urban population of over a billion people live in the next 15 years? This dissertation believes that urban infrastructures have a pivotal role in regulating and designing territory, for they create new opportunities of urban development and they can interfere both on constructed and natural environments.

In this thesis, an automatic road extraction algorithm for multi-spectral images is developed. The developed model extracts elongated structures from images by using edge detection, segmentation and clustering techniques. The study also extracts non-road regions like vegetative fields, bare soils and water bodies to obtain more accurate road map. The model is constructed in a modular approach that aims to extract roads with different characteristics. Each module output is combined to create a road score map. The developed algorithm is tested on 8-band WorldView-2 satellite images. It is observed that, the proposed road extraction algorithm yields 47 % precision and 70 % recall. The approach is also tested on the lower spectral resolution images with four-band, RGB and gray level. It is observed that the additional four bands provide an improvement of 12 % for precision and 3 % for recall. Road type analysis is also in the scope of this study. Roads are classified into asphalt, concrete and unpaved using Gaussian Mixture Models. Other linear objects such as railroads and water canals may also be extracted by this process. An algorithm that classifies drive roads and railroads for very high resolution images is also investigated. It is based on the Fourier descriptors that identify the presence of railroad sleepers. Water canals are also extracted in multi-spectral images by using spectral ratios that employ the near infrared bands. Structural properties are used to distinguish water canals from other water bodies in the image.

Esta tese teve como objetivo propor métodos para avaliar a elegibilidade dos modelos de concessão para projetos de infraestrutura e serviços públicos de transporte, bem como fundamentar uma teoria de estruturação desses tipos de contrato. Inicialmente o trabalho apresenta o contexto e os efeitos do surgimento de novas modalidades de concessão com a introdução da Lei de Parcerias Público-Privadas no Brasil. Investigou-se, em seguida, o estado da arte na teoria de estudos de valor das concessões, dos instrumentos de qualidade e das formas de divisão de obrigações e riscos entre o setor público e a iniciativa privada. As previsões legais vigentes para contratos administrativos dessa natureza foram também apontadas e explicadas. O núcleo da pesquisa teve como objetivo extrair o conhecimento empírico adquirido pela Administração Pública em quatro projetos selecionados de concessões em transporte. Foram analisadas as razões dentro de cada modelo desenvolvido e estabelecida uma crítica sobre as decisões de estruturação e resultados obtidos em cada empreendimento. O quadro geral das ferramentas aplicadas e a síntese da avaliação dos projetos foram desenvolvidos a partir dos estudos, com objetivo de traçar sugestões relevantes para o aprimoramento das concessões de serviços e obras de transporte no Brasil. Para o desenvolvimento completo da estrutura da concessão, foram propostos métodos de investigação das obrigações a serem transferidas ao parceiro privado, de repartição dos riscos e de utilização de mecanismos de controle de qualidade dos serviços e obras fornecidos.Entre as principais conclusões, evidenciou-se a urgência da aplicação de métodos de análise de valor das concessões durante os estudos prévios, tanto para avaliar as alternativas de estrutura dos modelos de outorga, como também comparar com o empreendimento realizado diretamente pelo Poder Público. / This thesis aimed to propose methods for assessing the eligibility of concession models for infrastructure and public transport services, and support a theory of structuring these kind of contracts. Initially, the research presented the context and purposes of concession modalities newly introduced by the brazilian Law of Public-Private Partnerships. It was investigated the state of the art on the theory about concessions evaluation, quality instruments and forms of spliting obligations and risks between the public and private initiative. The existing legal frame for this nature of public contracts were also mentioned and explained. The main objective of the research was to extract the empirical knowledgement acquired by the Public Administration in four selected transport concession projects. It were analyzed the reasons within each established model. It was developed some critique about the decisions on structuring and the obtained results on each endeavor. From these studies, it were developed the overall framework of the applied tools and the evaluation summary of the projects, aiming to outline relevant suggestions for the improvement of the concessions for transportation services in Brazil. For the full development of concessions structures, it were proposed methods of investigation about obligations to be transferred to the private partner, share the risk and use of mechanisms for quality control of works and services provided. Among the key conclusions, the study showed up the urgency of the application of concession evaluation methods during the precedent studies, both to assess the alternatives structures of models for concession, as well as to compare with the business conducted directly by the Government.

O trabalho apresenta de início uma investigação da evolução histórica do sistema viário de São Paulo como subsídio à compreensão da transformação que a cidade teve ao longo das décadas em sua configuração urbana e na forma pela qual as pessoas e veículos se deslocaram através da rede física de circulação. Foram analisados os aspectos viários dos planos urbanos, em muitos casos entendidos como planos viários, e da legislação urbanística de parcelamento do solo no período de 1895 a 2004. A partir dos resultados da investigação realizada, bem como da análise crítica das normas e manuais em vigor na cidade de São Paulo, em especial aqueles que tratam do estabelecimento da seção transversal típica das vias, o presente trabalho tem como objetivo propor uma contribuição à revisão da classificação viária da cidade de São Paulo. A revisão proposta recomenda que, na definição das funções que as vias possam ter dentro da rede viária urbana usualmente caracterizada pela relação entre os níveis de mobilidade e acessibilidade proporcionados ao tráfego veicular - sejam consideradas, de forma mais abrangente, as necessidades dos usuários não motorizados (pedestres e ciclistas) no que diz respeito às características geométricas da seção transversal. / The paper presents, at first, a research about the historic evolution of the roadway system in São Paulo as an aid to understand the changes the city went through, for decades, in its urban configuration and in the way people and vehicles moved through the circulation physical network. The paper analyzed the road aspects of urban plans which, many times were understood as roadway plans, and of the urban laws of land division during the period of 1895 to 2004. Based on the findings of the research, as well as the critical analysis of rules and manuals in effect in the City São Paulo, mainly those that address the establishment of a roadway-typical cross section, the present paper aims at suggesting a contribution to the roadway classification review of the City of São Paulo. The proposed review recommends, according to the definition of the roles that the roadways may play within the urban roadway network usually characterized by the relation between the mobility and accessibility levels provided to vehicle traffic to take into consideration, in a more comprehensive manner, the needs of those non-motorized users, (pedestrians and cyclists) in regard to the cross-section geometrical characteristics.

Transportinfrastruktursystem spelar en viktig roll i stadsutvecklingen. Nyttjandet av underjordiska utrymmen för transportsystem ökar alltmer och används som potentiella lösningar för att lösa urbaniseringsproblem. För att möta den snabba befolkningstillväxt som Stockholm står inför initierade regeringen Stockholmsöverenskommelsen 2013 som innebar en omfattande utbyggnad av tunnelbanenätet samt en ökad bostadsbebyggelse. Tunnelbaneutbyggnaden är i Sverige den första att genomföras på trettio år och projektet har i det tidiga skedet redan ändrats i omfattning i två etapper.  Syftet med studien är att bidra till en ökad förståelse inom området inför framtida projekt av samma karaktär. Målsättningen är att undersöka vilka faktorer som påverkar projektets benägenhet att ändras och hur dessa faktorer i sin tur påverkar projektledarens möjligheter att leda projektet. Problemet avgränsas till ett beställarperspektiv i tidiga skeden och studeras i en svensk kontext.  Forskningen har genomförts som en kvalitativ fallstudie. Fallstudien består av dels en intervjustudie dels en dokumentstudie. Det studerade fallet representerar projekt Akalla-Barkarby som är ett av de delprojekt som ingår i Stockholmsöverenskommelsen.  Studien har identifierat ett antal faktorer som antas påverka projektomfattningen till en större benägenhet att ändras. Dessa faktorer är relaterade till dels de förutsättningar som låg till grund för projektet i och med investeringsbeslutet dels komplexiteten i projektsystemet. Dessa faktorer skapar osäkerheter och begränsar projektledarens möjligheter att leda projektet. / Transportation infrastructure systems play an important role in urban development. The use of underground spaces for transport systems is increasing and is viewed as a potential solution to solve urbanization problems. To meet the rapid population growth that Stockholm is facing, the government initiated the Stockholm Agreement in 2013, which entailed an extensive expansion of the metro system and an increased housing development. The metro system expansion in Sweden is the first to be completed in thirty years and the project has in the early stages already changed in scope twice.  The purpose of the study is to contribute to an increased understanding in the field for future projects of the same nature. The aim is to investigate the factors that affect the project's propensity to change and how these factors in turn affect the project manager's opportunities to lead the project. The problem is limited to a Client perspective in the early stages and is studied in a Swedish context. The research has been carried out as a qualitative case study. The case study consists partly of an interview study and partly of a document study. The case represents the Akalla - Barkarby project, which is one of the sub-projects included in the Stockholm Agreement.  The study has identified several factors that are assumed to influence the project scope to a greater tendency to change. These factors are related partly to the preconditions of the project based in the investment decision and partly to the complexity of the project system. These factors create uncertainties and limit the project manager's opportunities to lead the project.

Between the 1930s and mid-1980s, North Carolina became one of the most industrialized states in the country, with more factory workers, as a percentage of the total workforce, than any other state. And yet, North Carolina generally retained its rural complexion, with small factories dispersed throughout the countryside, instead of concentrated in large industrial cities. This dissertation asks two essential questions: first, how did this rural-industrial geography come to be, and second, what does the creation of this geography reveal about the state of the American political economy in the post-World War II era? I argue that rural industrialization was a central goal of North Carolina’s postwar political leaders and economic development officials. These industry hunters, as I call them, wanted to raise their state’s per capita income by recruiting manufacturers to develop or relocate operations in North Carolina. At the same time, they worried about developing large industrial cities or mill villages, associating them with class conflict, congestion, and a host of other ill-effects. In the hopes of attracting industry to its countryside, the state invested heavily in its secondary roads and highways, increasing the accessibility of rural communities. In their pursuit of rural industrialization, however, North Carolina also constructed a political economy that anticipated the collapse of the New Deal state. While historians typically see New Deal liberalism as the prevailing form of statecraft in the postwar United States, North Carolina achieved economic growth through a model that state officials termed “accessible isolation.” What accessible isolation meant was that North Carolina would provide industries with enough of a state apparatus to make operating a factory in a rural area possible, while maintaining policies of low taxes, limited regulations, and anti-unionism, to make those sites desirable. Essentially, industry hunters offered industrial prospects access to a supply of cheap rural labor, but isolation from the high wages, labor unions, government regulations, and progressive tax code that defined New Deal liberalism. Accessible isolation was attractive to businesses in postwar America because it offered a “business-friendly” alternative to the New Deal, and factories began sprouting throughout rural North Carolina. But the success of accessible isolation was built on a shaky foundation. Indeed, most of the employers persuaded by its promises were those in low-wage, labor-intensive industries, making North Carolina’s rural communities especially vulnerable to transformations in the global economy by the late twentieth century. / History

For this purpose, we approached the analysis of transportation policies, planning and programs promoted both by state and federal government; a survey of the State’s effectiveness index in transportation investments from 2006 to 2014, with basis on data obtained from the Goiás Transparency Portal, State Secretariat of Management and Planning, “Portal Brasil”, Program of Investment in Logistics and Mauro Borges Institute, as well as a detailed analysis of the factors listed as competitive differentials of the project was performed. This work allowed us to conclude that not only the constant project implementation delays and interferences have compromised the effectiveness of the results expected by PLMG regarding the aerial and rail transport modalities and storage services, but also the low effectiveness index of transportation infrastructure investments are factors impairing the full development of the state. / A partir do entendimento que o Desenvolvimento do Estado de Goiás está diretamente ligado a disponibilidade e qualidade de infraestrutura de transporte, esta pesquisa teve como objetivo analisar o projeto, em andamento a mais de 15 anos, da Plataforma Logística Multimodal do Estado de Goiás, buscando verificar se os diferenciais competitivos propostos inicialmente podem ainda fomentar o desenvolvimento regional, bem como levantar as condições da infraestrutura de transporte do Estado. Com esse intuito, foram analisadas as políticas, planos e programas dos governos estadual e federal voltados para o setor de transporte; levantado o índice de efetividade de investimento do governo estadual neste segmento (2006 a 2014), através de dados obtidos junto ao Portal da Transparência do Estado de Goiás, Secretaria de Estado de Gestão e Planejamento de Goiás, Portal Brasil, Programa de Investimento em Logística e Instituto Mauro Borges e uma analise minuciosa da situação dos fatores elencados como diferenciais competitivos do projeto. O trabalho permitiu concluir que os constantes adiamentos e interferências na implantação do projeto comprometeram a efetividade dos resultados esperados pela PLMG, principalmente nos modais aéreo e ferroviário e nos serviços de armazenagem além do baixo índice de efetividade dos investimentos em infraestrutura de transporte, fatores que vem impedindo o pleno desenvolvimento do estado.

Este trabalho apresenta uma visão sobre a conceituação e o desenvolvimento tipológico das vias expressas urbanas durante a primeira metade do século XX. Partindo do entendimento das condições que determinaram a sua invenção para, em seguida, analisar o desenvolvimento técnico dessas infraestruturas nos campos da engenharia e do urbanismo. As promissoras possibilidades que as novas velocidades do automóvel ofereciam no início do século entraram imediatamente em conflito com a estrutura física, histórica e social da cidade tradicional. Para que fosse possível mediar tal embate, seria necessário um novo pacto social do uso da rua que segregasse pessoas e veículos, separando-os entre a calçada e o leito carroçável. É a partir da regulamentação do espaço viário dos centros urbanos - concebida pelos primeiros engenheiros de tráfego, nos Estados Unidos, entre as décadas de 1910 e 1920 - que a rua deixa de ser primordialmente espaço público para se tornar infraestrutura, dedicada ao transporte urbano de pedestres e motoristas. No entanto, a partir da década de 1930, devido ao crescimento dos acidentes de trânsito e dos congestionamentos, tornou-se necessário o desenvolvimento de um novo tipo de infraestrutura, que contemplasse as necessidades do carro, permitindo-lhe trafegar em velocidade com segurança. Era preciso construir um espaço absolutamente segregado, sem nenhum tipo de obstáculo, numa ruptura radical entre suas pistas e o restante da cidade. É dessa forma que surge a via segregada de acesso limitado - a via expressa -, um dos momentos mais contundentes da ideologia rodoviarista no espaço urbano, transformando radicalmente sua estrutura física e social. Ao longo do desenvolvimento da via expressa como tipologia por diversos profissionais, na primeira metade do século XX, sua relação com o espaço urbano é enfrentada de forma dialética. Enquanto algumas propostas negavam a cidade tradicional na sua busca por segregação através de novas formas de urbanismo, outras a enfrentaram, cortando a cidade com suas pistas, tornando os centros urbanos acessíveis ao automóvel. A partir da segunda metade do século XX, a síntese se estabelece. Ambas as formas de relação entre rodovia e cidade - de negação e enfrentamento - prosperam, tornando-se parte da realidade inexorável de uma nova condição urbana. Por fim, em contrapartida, a via expressa é analisada de forma abstrata, através da leitura de aspectos culturais, do conceito de \"progresso\" como um mito contemporâneo, bem como as noções de \"lugar\" e \"não-lugar\", à luz das condições impostas pela modernidade do capitalismo pós-industrial. / This paper presents a vision on the conceptualization and the typological development of urban expressways during the first half of the 20th century. Starting from the understanding of the conditions that determined its invention, and furtherly, analyzing the technical development of these infrastructures in the fields of engineering and urbanism. The promising possibilities offered by the automobile at the turn of the century immediately clashed with the physical, historical, and social structure of the traditional city. In order to mediate such a conflict, a new social pact regarding street use would be needed, managing the segregation between people and vehicles. In the United States, between the 1910s and 1920s, the street regulation conceived by the first traffic engineers transformed the public space of the street into infrastructure, dedicated almost exclusively to the urban transportation of Pedestrians and drivers. However, since the 1930s, due to the increase in traffic accidents and congestion, it became necessary to develop a new type of infrastructure, which would meet the needs of the car, allowing it to travel safely at a proper speed. It has become necessary the construction of an entirely segregated space to the car, rid of any kind of obstacle, in a radical rupture between its tracks and the rest of the city. The urban limited-access highway - also known as the \"expressway\" - emerges along this scenario, being one of the most striking moments of the car culture in urban space, radically transforming its physical and social structure. Throughout the development of the expressway as typology by several professionals, in the first half of the twentieth century, its relationship with urban space is dialectically confronted. While some proposals \"denied\" the traditional city through new forms of road design and urbanism, others \"confronted\" it, cutting through the city with its tracks, making urban centers accessible to the automobile. From the second half of the twentieth century, synthesis is established. Both forms of relationship between highway and city - of denial and confrontation - thrive, becoming part of the inexorable reality of a new urban condition. Finally, the expressway is analyzed in a more abstract approach, through the reading of some of its cultural aspects. The concept of \"progress\" as a contemporary myth is also mentioned, as well as the notions of \"place\" and \"non-place\", regarding the conditions imposed by the modernity of post-industrial capitalism.
