Geotechnical investigations for the Gautrain Mass Transit Rapid Rail Link over dolomite bedrock in the Centurion area, South Africa

Momubaghan, Glory Adeoye 22 May 2013 (has links)
The Gautrain Rapid Rail Link is a state-of-the-art rail route and one of the ten Spatial Development Initiatives planned in Gauteng Province, South Africa. The route comprises two links, namely a link between Tshwane (Pretoria) and Johannesburg and a link between OR Tambo International Airport and Sandton. A total of 10 stations are linked by approximately 80 kilometres of rail along the proposed route. Between Johannesburg and Pretoria in the southern Tshwane region, the rail alignment is underlain by dolomite bedrock for approximately 15km in the vicinity of Centurion between Nelmapius Drive and The Fountains, including nearly 6km elevated on a viaduct. The stability of the rapid rail link constructed over the dolomitic sections was considered a major project risk due to its proneness to sinkholes and subsidences along this route. Construction on heterogeneous soils, pinnacled bedrock and other geohazards posed major challenges to the construction team. To facilitate detailed design and adapt proper foundation options for the viaducts founded over the dolomitic terrain, rigorous and comprehensive ground investigations were conducted by the Bombela Civils Joint Venture (BCJV). This work presents the different ground investigation methods used and how the results have led to the adoption of five suitable foundation solutions namely: large diameter shafts to rock, piles to rock, floating foundations over grouted ground, spread footings on shallow bedrock and concrete U shaped structures.

A Proactive Approach to Train Control

Thurston, David Frank January 2012 (has links)
The main objective in optimizing train control is to eliminate the waste associated with classical design where train separation is determined through the use of "worst case" assumptions to calculate Safe Braking Distances that are invariant to the system. In fact, the worst case approach has been in place since the beginning of train control systems. Worst case takes the most conservative approach to the determination of train stopping distance, which is the basis for design and capacity of all train control systems. This leads to stopping distances that could be far more than actually required under the circumstances at the time the train is attempting to brake. A new train control system is proposed that utilizes information about the train and the conditions ahead to optimize and minimize the Safe Braking Distance. Two methods are proposed to reduce safe braking distance while maintaining an appropriate level of safety for the system. The first introduces a statistical method that quantifies a braking distance with various hazards levels and picks a level that meets the safety criteria of the system. The second method uses train mounted sensors to determine the adhesion level of the wheel and rail to determine the appropriate braking rate for the train under known circumstances. Combining these methods provides significant decreases in Safe Braking Distances for trains. A new train control system is utilized to take advantage of these features to increase overall system capacity. / Electrical and Computer Engineering

Implementing mass transit: a case study of the CyRide system in Ames, Iowa and its implications for mass transit in Manhattan, Kansas

Zevenbergen, Philip G. January 1900 (has links)
Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / John W. Keller / The purpose of this document is to use an existing transit system as the standard by which another community can model their own. It begins with the discussion of a brief history of mass transit in the United States—focusing on the detail that competing automobile manufacturers began the demise of transit ridership in this nation. As the 1950s came to a close, the nation’s transit systems saw the peak of ridership. However, the post-war era brought about massive suburbanization and more automobiles per household. The American no longer needed to ride transit, except for those still living in the dense urban cores of cities like New York City. The document moves into the discussion of the fundamentals of mass transit. It explains the importance of population base, ridership, and funding. Depending on the type of system, a minimum population base is recommended in order to support the proper system. Ridership is a key focus of transit, for without it, a community is just wasting resources. Finally, funding is very important. No transit system can support itself on fares alone and still remain a viable alternative to the automobile. Transit systems must procure funding from a variety of sources including all levels of government in order to obtain sufficient revenue to operate successfully. The heart of the document focuses on the CyRide bus system in Ames, Iowa—serving the Ames community and Iowa State University since 1976. CyRide is a special system in that it serves a total population of only 54,000, but sees an annual ridership of 5 million. Their success is based on a longstanding relationship with the community complimented by staff that posses the passion to ensure the highest quality service day-in and day-out. This report discusses the fine details of how that system functions on all levels. The document concludes with the discussion of Manhattan, Kansas—a city with approximately the same population as Ames, and is home to Kansas State University, which as approximately the same student enrollment as Iowa State. Manhattan currently does not have a transit system, but is seeking to implement one in the coming years. The overall intent of this report is to draw conclusions based on the performance of CyRide and provide recommendations to the City of Manhattan regarding the implementation and operation of a transit system.

Percepção da sociedade e dos especialistas sobre os benefícios dos sistemas de transporte público urbano sobre trilhos / Society and specialists perception about the generated profits with urban public rail transportation systems

Baria, Igor 25 September 2009 (has links)
Os objetivos deste trabalho são dois: avaliar a percepção da sociedade e dos especialistas em transporte sobre os benefícios alcançados com a implantação de sistemas de transporte público urbano sobre trilhos e verificar se a percepção dos especialistas é alinhada com a percepção da sociedade. O trabalho foi desenvolvido a partir de uma pesquisa bibliográfica para identificação dos benefícios do transporte público sobre trilhos. Após definidos os benefícios foi aplicada uma pesquisa, de caráter exploratório, utilizando a escala de Likert, à sociedade, mais especificamente a alunos de graduação de cursos universitários na região metropolitana de São Paulo num total de 433 respondentes, distribuídos em 7 locais distintos. Em seguida foi realizada uma pesquisa junto a especialistas em transporte, com utilização de uma planilha para avaliação dos benefícios com base no Método de Análise Hierárquica - MAH. Na pesquisa com especialistas obteve-se 34 planilhas distribuídas em 4 grupos distintos. Os resultados mostram que a sociedade e os especialistas possuem uma percepção bastante positiva dos benefícios gerados pela implantação de sistemas de transporte público urbano sobre trilhos, havendo, no entanto, diferenças sensíveis nas avaliações, que refletem na ordem de importância dos benefícios. / The objectives of this work are, over all, two: evaluate the society´s and transportation specialists the perception on the benefits, reached with the implantation of urban public transport on tracks systems and to verify if the perception of the specialists is aligned up with the perception of the society. The work was developed from a bibliographical research that had the goal to identify the benefits of the public transport on tracks. After defined the benefits the research was applied to the society using the Likert´s scale, in exploratory way, more specifically the graduation´s pupils of university courses in the metropolitan region of São Paulo in a total of 433 respondents, distributed in seven distinct places. After that was carried through a research next to transportation´s specialists, with the resource of a spread sheet for evaluation of the benefits on the basis of the Analytic Hierarchical Process - AHP. About the research with specialists, one got 34 spread sheets distributed in four distinct groups. The results show that the society and the specialists possess a sufficiently positive perception about the benefits generated for the implantation of urban public transport on tracks systems, having, however, sensible differences in the evaluations, that they reflect in the order of the benefits importance.
