Vliv kapacitní dopravní infrastruktury na socioekonomický rozvoj obcí ve Středočeském kraji / Effect of high-capacity transport infrastructure on socioeconomic development of municipalities in the Central Bohemia region

Barek, David January 2016 (has links)
High capacity transport infrastructure is often referred to as a one of key factors in regional development. The aim of this study is specify effects of capacity transport infrastructure in relation with accessibility to Prague on possible municipalities development in the Central Bohemia region. Basis of this research is identify indicators, that are significantly affected existence of transport infrastructure and accessibility strong core and then to formulate future development of concerned areas. We used spatial analysis methods with demarcation time accessibility zones for accessibility research. Long term development is monitored using index changes of relevant indicators between 2001 and 2011 and their significance are evaluated by analysis of variance. Key factors in municipalities on transport infrastructure were compared with SO ORP. Characteristic of significant effects in area has provide identification different values in development. In spite problematic data base this research confirmed development effects of high capacity roads, especially in demographic terms, but they are significantly influenced by the time accessibility to region core and area economic base. The results can be used as a document for deciding on territorial investment and to prediction effects for the planned transport...

Transport infrastructure slope failures in a changing climate

Wilks, Joanna H. January 2015 (has links)
Failure of slopes adjacent to the UK transport infrastructure causes delays and these are expensive assets to repair and maintain. Understanding the processes that lead to failure will assist asset managers both now and in the future in the context of a changing climate. The EPSRC-funded multidisciplinary FUTURENET project investigated the effect of climate change on the resilience of the UK transport network and this thesis is a part of that project considering the weather patterns leading to slope failures along transport infrastructure slopes within the UK. To that end a series of slope failure case studies were investigated to understand the processes leading to failure. These were compiled using nationally held datasets as well as news reports. This research used data from the FUTURENET partners that hold national data sets and asset management information. This shows the wide reaching remit of a multidisciplinary collaborative project such as FUTURENET, but also highlights the limitations of datasets collected and used for very specific purposes and not necessarily suited to wider research. From these case studies a suite of slope failure weather thresholds were developed. These thresholds consider the antecedent period, water content within the slope through the soil moisture deficit and triggering rainfall through comparison to the long term average rainfall. Consideration was given to possible future weather using weather event sequences (WESQs), possible weather patterns for 2050 derived from the UKCP09 climate projection data. By considering these possible weather patterns with the slope failure thresholds a picture of a possible future was evaluated.

No. of bitstreams: 1 cruz_damo_dr_prud.pdf: 5519015 bytes, checksum: 59c026cc8aef22a81e0be8dead1d3092 (MD5) Previous issue date: 2017-12-04 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / A relação assimétrica e desigual entre Brasil e Paraguai na América do Sul demonstra a complexidade do subsistema regional, que deve ser lida não só a partir do contexto econômico, mas também do contexto (geo) político regional, associado por sua vez ao sistema-mundo. Se por um lado, a ampliação da exportação de commodities e dos acordos de integração regional demandam o planejamento e investimento em projetos de infraestruturas, sobretudo de transportes; por outro lado, a fragilidade institucional e financeira dos acordos regionais contribui para o atraso no cronograma de execução desses projetos. A partir da análise do processo de integração regional sul-americano, considerando o Mercado Comum do Sul (MERCOSUL), o Conselho Sul-americano de Infraestrutura e Planejamento/Iniciativa para a Integração da Infraestrutura Regional Sulamericana (COSIPLAN/IIRSA), e o papel de liderança desempenhado pelo Brasil, afirmamos que existe uma estreita relação entre integração regional e geopolítica, na qual os projetos internacionais de infraestruturas podem ser considerados como pontos de encontro entre ambos. / The asymmetric and unequal relationship between Brazil and Paraguay in South America demonstrates the complexity of the regional subsystem, which must be read not only from the economic context, but also from the regional (geo) political context, associated in turn with the world system. If, on the one hand, the expansion of commodities exports and regional integration agreements demand planning and investment in infrastructure projects, especially transportation; on the other hand, the institutional and financial fragility of the regional agreements contributes to the delay in the execution schedule of these projects. Based on the analysis of the South American regional integration process, considering the Southern Common Market (MERCOSUL), the South American Council on Infrastructure and Planning / Initiative for the Integration of Regional South American Infrastructure (COSIPLAN / IIRSA), and the leading role played by Brazil, we affirm that there is a close relationship between regional and geopolitical integration, in which international infrastructure projects can be considered as meeting points between the two. / FAPESP: 2014/09913-1

Indirect impact of landslide hazards on transportation infrastructure

Postance, Benjamin F. January 2017 (has links)
This thesis examines the indirect impact of natural hazards on infrastructure networks. It addresses several key themes and issues for hazard assessment, network modelling and risk assessment using the case study of landslides impacting the national road network in Scotland, United Kingdom. The research follows four distinct stages. First, a landslide susceptibility model is developed using a database of landslide occurrences, spatial data sets and logistic regression. The model outputs indicate the terrain characteristics that are associated with increased landslide potential, including critical slope angles and south westerly aspects associated with increased rates of solar irradiance and precipitation. The results identify the hillslopes and road segments that are most prone to disruption by landslides and these indicate that 40 % (1,700 / 4,300 km) of Scotland s motorways and arterial roads (i.e. strategic road network) are susceptible to landslides and this is above previous assessments. Second, a novel user-equilibrium traffic model is developed using UK Census origin-destination tables. The traffic model calculates the additional travel time and cost (i.e. indirect impacts) caused by network disruptions due to landslide events. The model is applied to calculate the impact of historic scenarios and for sets of plausible landslide events generated using the landslide susceptibility model. Impact assessments for historic scenarios are 29 to 83 % greater than previous, including £1.2 million of indirect impacts over 15 days of disruption at the A83 Rest and Be Thankful landslide October 2007. The model results indicate that the average impact of landslides is £64 k per day of disruption, and up to £130 k per day on the most critical road segments in Scotland. In addition to identifying critical road segments with both high impact and high susceptibility to landslides, the study indicates that the impact of landslides is concentrated away from urban centres to the central and north-west regions of Scotland that are heavily reliant on road and haulage-based industries such as seasonal tourism, agriculture and craft distilling. The third research element is the development of landslide initiation thresholds using weather radar data. The thresholds classify the rainfall conditions that are most commonly associated with landslide occurrence in Scotland, improving knowledge of the physical initiation processes and their likelihood. The thresholds are developed using a novel optimal-point threshold selection technique, high resolution radar and new rain variables that provide spatio-temporally normalised thresholds. The thresholds highlight the role of the 12-day antecedent hydrological condition of soils as a precursory factor in controlling the rain conditions that trigger landslides. The new results also support the observation that landslides occur more frequently in the UK during the early autumn and winter seasons when sequences or clustering of multiple cyclonic-storm systems is common in periods lasting 5 to 15 days. Fourth, the three previous elements are combined to evaluate the landslide hazard of the strategic road segments and a prototype risk assessment model is produced - a catastrophe model. The catastrophe model calculates the annual average loss and aggregated exceedance probability of losses due to the indirect impact of landslides in Scotland. Beyond application to cost-benefit analyses for landslide mitigation efforts, the catastrophe model framework is applicable to the study of other natural hazards (e.g. flooding), combinations of hazards, and other infrastructure networks.

Estudo da análise de custo-efetividade no planejamento de políticas público-privadas de longo prazo integrada à análise de custo-benefício / Study of cost-effectiveness in planning public-private integrated long-term policies to cost-benefit

Miyabukuro, Sandra Bittencourt January 2014 (has links)
Celebra-se no Brasil um momento de crescimento econômico e reconhecimento mundial. Entretanto, tal crescimento pode ser bastante ruim para um país que há muitos anos não investe em infraestrutura, e, consequentemente, passou a apresentar gargalos neste setor. Caracterizada como um estilo de administração burocrático e ineficiente, a gestão pública brasileira apresenta qualidade de serviços bastante inferiores se comparada ao setor privado. A tomada de decisão pautada em análises e avaliações econômicas ainda é tratada de forma bastante primária, notadamente no meio público. A inserção deste tipo de avaliação na formulação de políticas públicas encontra-se pouco difundida nesse meio em função do baixo grau de sofisticação técnica dos instrumentos aplicados no país, notadamente no que tange à distribuição de verbas. A análise econômica, tema deste trabalho, atua na esfera prática da formulação e análise de projetos público-privados concernentes à infraestrutura de transportes através da escolha do método de custo-efetividade (ACE) como complementar à tradicional análise de custo-benefício (ACB). De posse das informações necessárias, é sugerida uma metodologia que permita a avaliação econômica de projetos do referido setor a partir do cálculo dos indicadores de viabilidade tradicionais (VPL, TIR e B/C). Por fim, é realizado um estudo piloto da concessão da BR-163, no Estado do Mato Grosso, elaborado com o intuito de avaliar a adequação da metodologia bem como o formato dos resultados. A proposta envolve a possibilidade de eleger prioridades a partir de uma simplificada aplicação da análise de custo-efetividade (ACE), a partir da relação de intervenções possíveis ao longo da concessão com a possibilidade da redução no número de acidentes em pontos específicos da rodovia, vislumbrando o máximo benefício à sociedade. Os resultados obtidos a partir dos procedimentos descritos demonstram que a metodologia sugerida pode servir como ferramenta de apoio à tomada de decisão, notadamente, do governo e do ente privado. / Brazil is celebrated in a time of economic growth and global recognition . However , such growth can be quite bad for a country that for many years does not invest in infrastructure, and consequently began to show bottlenecks in this sector. Characterized as a style of bureaucratic and inefficient administration, the Brazilian public management presents quality services is much lower compared to the private sector . Decision making guided by analysis and economic evaluations is still treated so very incipient , particularly in the public medium . The insertion of this type of evaluation in the formulation of public policies lies not widespread in this environment due to the low degree of technical sophistication of the instruments used in the country , notably in terms of the distribution of funds . The economic analysis , subject of this work , acts in the sphere of practical design and analysis concerning public- private projects to transport infrastructure through the choice of the method of costeffectiveness as a complement to traditional cost-benefit analysis. Of the necessary information , it is suggested a methodology that allows the economic evaluation of projects of that sector from the traditional calculation of viability indicators . Finally , a pilot grant from the BR-163 study in the state of Mato Grosso , developed with the aim to assess the appropriateness of the methodology and the format of the results is performed . The proposal involves the possibility of choosing priorities from a simplified application of costeffectiveness from the list of possible interventions along with granting the possibility of reducing the number of accidents at specific points of the highway , glimpsing the maximum benefit to society. The results obtained from the procedures described demonstrate that the suggested methodology can serve as a support for decision-making, notably , the government and the private entity tool.
