High-speed rail (HSR) has been gaining acceptance worldwide with development of rail technology and rising concerns over climate change and congestion in airports and on roads. The implementation of high-speed rail lines also plays an important role in reshaping the travel patterns and activities of people and consequently change the ways cities develop. An interesting indirect implication of HSR is the potential for megalopolis formation created by fusion of multiple cities linked by HSR. An overall consensus is present in the existing theoretical literature as to what development impacts may be from the HSR investment, including the importance of the resulting agglomeration externalities and formation of megalopolises. However, the complexity of the issue leaves the questions about the causal effect of HSR on economic growth open. This thesis studies the existing empirical evidence and experiences of HSR corridors in Japan, France and Germany to explore qualitatively the phenomenon of "megalopolis" formation as a result of a HSR link, and the evidence of economic development effects on urban areas along these corridors. Portugal among other countries is also planning the deployment of a HSR network in the near future as an effort to stimulate the country's economy and to integrate with the rest of the European Union. The findings and lessons from the case studies are applied to Portugal's proposed Lisbon-Porto HSR corridor. Several possibilities of future scenarios of megalopolis forms and the associated impacts are discussed and analyzed. As a result of improved accessibility and increased interaction between the cities stimulated by HSR, emergence of a megalopolis is possible in different forms along the planned Lisbon-Porto HSR corridor. The critical factor for the formation of a megalopolis is the increased interaction between the cities driven by newly generated traffic and increase in the number of one-day trips. These new travel patterns within a megalopolis may lead to either creation of new economic growth or redistribution of economic activity. The spatial distribution of growth is non-uniform, which may essentially lead to potential winners and losers from HSR. This research is intended to be of value to policy-makers in the railway industry.

The goal of this thesis is to provide guidance for regional rail network planning to achieve the maximum benefits in terms of economic growth, passenger satisfaction, and environmental sustainability. The hypothesis is that a regional intercity rail network can increase accessibility allowing the connected cities to function as a single economy thus increasing overall productivity. The Basque Y high speed rail (HSR) project in northern Spain will be used as a case study for this thesis. This new system has the potential to significantly reduce regional travel times but due to poor station placement and inadequate operational foresight, speed-focused planning has left key regional markets inaccessible. This thesis recommends a shift in planning that enables regional economic cohesion and increased system ridership through a focus on high quality rail (HSR) that includes the complete door-to-door journey with a customer oriented approach to convenience, comfort, and reliability. The highly successful Swiss rail network serves as a guide as to how to combine the superior speed of the Spanish system with the superior quality of the Swiss system to provide one which can achieve maximum benefit from the Basque Y investment. A comparison with the Spanish system shows what the Basque Y should do differently in terms of planning and service and accessibility maps help to illustrate the Basque Y system under different planning scenarios. Planning issues examined are station location, integration with local transit systems, and operational fares, frequencies, and scheduling. Finally the regional system is examined politically and a strategy is sketched that can enable the region to modify the plan to obtain the benefits of a high speed and high quality regional rail system.

Globalization has magnified the role of regions, restructuring social and economic relationships into networks that span increasing distances. At the same time, greater attention is paid to urban quality, as non-vehicular modes and compact forms of development become critical in an environmentally conscious world. Within this context, increasing interest and adoption of high-speed rail (HSR)-- mode with spatial sustainability objectives--is unsurprising. HSR has the potential to integrate cities into mutually supportive networks across long distances while also supporting more sustainable forms of development. For HSR to become a sustainable investment, however, requires coordinated policy efforts across levels of government and at different points in a project's life-cycle. This investigation spans multiple scales of the physical environment and institutional sphere, examines ways of coupling institutional change with technological change, and addresses the importance of uncertainty as a driver of system behavior. We focus on inter-jurisdictional relationships, with special attention paid to smaller intermediate cities brought within one-hour's travel time of a larger metropolis by HSR services. Mid-distance service (<250 km) has strong spatial implications and can expand connections to the scale of new discontinuous regions--single labor and commercial markets that spans long distances but do not include all intermediate areas. Both Portugal and the United Kingdom (UK) are planning HSR systems that will provide mid-distance service. Through stakeholder interviews and a critical reading of the literature, this thesis develops a theory-based assessment of goals for regional restructuring, studies existing and planned Portuguese rail-commuter-cities, and compares HSR planning in Portugal and the UK. We see evidence that HSR can induce new ways of thinking about urbanization, regional connectivity, and governance. The scope of change that might be put into effect by HSR creates greater incentives for collaboration than those that normally exist. We find that local knowledge and policy will improve HSR design and implementation by helping to ensure smooth interfaces between HSR and existing urban mobility systems. Developing decision-making structures that will work across geographic scales and sectors of government, and long-term uncertainty, will be critical in helping HSR achieve 3E--Economic, Environmental and Equitable--sustainability.

The ongoing discussion about the future implementation of high-speed rail (HSR) in the Northeast Corridor (NEC) is full of questions on the feasibility of HSR and the ability of Amtrak to implement it. Indeed, the introduction of the Acela Express in the past decade was not free from operating problems, but even with trains running below their full potential, the Amtrak NEC had substantial market growth. Thus, it is not clear if a true HSR service is feasible in the NEC, and if the current prospects are potentially effective. To evaluate the performance of the NEC and its main services in FY 2002-2012, and make inferences about HSR in the NEC for the next 30 years, we use productivity analysis. We employ a non-parametric single factor productivity (SFP) Törnqvist trans-log index approach with several metrics. We set ridership, revenue, revenue passenger-miles (RPM), and available seat-miles (ASM) as outputs, and operating costs as input. In this way, we provided guidelines and a robust structure of analysis that can be useful for subsequent passenger rail productivity studies. We find that the NEC experienced highly volatile, but considerable productivity growth in FY 2002-2012 (in the range of ~1-3% per year). Amtrak increased its ability to fill up and economically exploit the available capacity, but did not perform equally well on the supply side. Service changes, technical problems with train sets, targeted capital investments, and economic recession and recovery were the main drivers of productivity change. The Acela Express and Northeast Regional were very sensitive to external events, had large economies of scale, and implemented slow adjustment of capacity via rolling stock and infrastructure improvements, which varied depending on the service. The characteristics of the NEC reveal a potential for a successful introduction of HSR, but although Amtrak's Vision for HSR in the NEC is realistic (in terms of productivity), it is risky and perhaps the time scale is not ambitious enough. We recommend revising the current projections, incorporate additional planning approaches, accelerate key stages of the Vision and include the FAA in the planning process.

High Speed Rail is a mode that gains popularity every day. Many countries have such a network and others are on the way to adopting one. Greece, which is part of the European Union, is one of those countries that are looking forward to such a network. This thesis will investigate the transportation sector of Greece, its governance and funding issues. Moreover, it will go into depth regarding the mode of High Speed Rail. The projects and issues related to this mode will be presented. Another issue of concern will be the evaluation of economic impacts of transportation investments and high speed rail specifically. A thorough literature review regarding the different methods and software packages that exist will be presented. Also, a method suitable to the Greek standards and characteristics will be proposed. Last, we create a screening model for High Speed Rail. This model aims to be used from countries similar to Greece, in order to realize whether it is worth it to start thinking of constructing such a network or not. HSR possibilities in Greece and Portugal are compared using the screening model.

High-Speed Rail (HSR) has been expanding throughout the world, providing various nations with alternative solutions for the infrastructure design of intercity passenger travel. HSR is a capital-intensive infrastructure, in which multiple subsystems are closely integrated. Also, HSR operation lasts for a long period, and its performance indicators are continuously altered by incremental updates. With this background, design and monitoring of lifecycle properties, or "ilities", is an important factor to achieve long-term successful operation. This thesis aims to analyze and evaluate dynamic behaviors of "ilities" and their interactions in HSR operation. After the literature review and the study of industrial trends about HSR "ilities", safety, availability and profitability are chosen as key "ilities" which should be monitored in HSR operation. The Tokaido Shinkansen in Japan, and Amtrak's service in the US Northeast Corridor (NEC) are chosen as cases to study "ilities" trends. In the Tokaido Shinkansen, three "ilities" form a positive feedback loop to make HSR operation successful. The NEC shows high profitability, but it does not perform as well in terms of safety and availability due to several systemic factors. System Dynamics (SD) is applied to visualize interactions of "ilities" and other variables of interest. Qualitative causal loop diagrams (CLD) reveal several feedback loops affecting "ilities". In particular, the integration of train operation and infrastructure / rolling stock management results in the emergence of major feedback loops which cannot easily be captured by other methodologies. Qualitative SD models are converted into quantitative SD models, and numerical simulations are run to further understand the structure of causal loop diagrams. Estimated parameters in the Tokaido and the NEC suggest the different relationships among "ilities" and other variables. Further, sensitivity analyses are conducted to evaluate how different policies affect "ilities" in future HSR operations.

Taiwan High Speed Rail started its operation on March 2, 2007. To ensure the safe operation and comfortable rides, the inspection of rail irregularity is crucially important. The Japanese AF-55 slab track and the German Rheda 2000 slab track are both used in Taiwan High Speed Rail. These two kinds of slabs are very different from each other in their construction methods, rehabilitation, and maintenance.Due to the repeated high speed heavy load, the irregular deformation of the rail geometry, such as irregularity in gauge, alignment, superelevation, surface and twist etc, is inevitable. Therefore, to dominate the situations of the irregularity and keep it in a reasonable range becomes the primary job. This study uses the data collected from 10 meter chord based on versine inspection method by rail-inspection car EM120, and then derives 20 meter chord and 40 meter chord from the data by applying Multiple-Precision floating point number arithmetic. The collected data will be divided, every 200 meters as one section, in terms of the different chords, types of slabs, and types of constructions. Then these data will be analyzed and calculated to obtain the average value, maximum value and P value. Finally, the rail irregularity in these two types of slab will be found. The study shows the causes and the characteristics of the rail irregularity between Japanese slab track and German slab track. Also this study discovers the unique reasons of the rail irregularity happening in the two special slabs and their topographic conditions. Meanwhile, this study can rapidly find out the locations and possible causes of rail irregularity, which is high-priority in rail rehabilitation. Furthermore, this result of the study can be used in rail maintenance system in order to increase the safety of operation and comfortable rides, and to extend the life-cycle of rail and rolling stocks.

There are a lot of transportation industry have the phenomenon that ridership exists significantly difference between peak hour and off-peak hour, resulting congestion problem in peak hour. In order to induce passengers shift from peak hour to off-peak hour, we need a better understanding in passengers’ departure time choice behavior. This study adopts Taiwan High Speed Rail (THSR) as a case study to identify THSR leisure passengers’ perceptions of the essential factors that affect departure time choice. In the earlier departure time choice relevant literature paid little attention in returning trip. In fact there may be exist differences and association between outgoing trip and returning trip. Therefore this study analysis THSR leisure passengers’ both outgoing trip and returning trip departure time choice behavior. Moreover, this study using hybrid choice model to included psychological factors that affect passengers’ departure time choice behavior. The findings of this study provides empirical evidence that no matter in outgoing trip or returning trip THSR passengers’ departure time choice will be affected by delay time, fares and psychological factors. This study also found that passengers’ departure time choice behavior in outgoing trip and returning trip will affect each other. The conclusions of this study have implication for THSR to design appropriate products that can balance difference between peak hour and off-peak hour. Key words: Departure Time Choice; Hybrid Choice Model; High Speed Rail; Leisure Passengers

A rail-to-rail op-amp with high stability over temperature variation at 1-V supply voltage is presented in this thesis. It incorporates a modified CM adapter and a modified bandgap reference. First, the modified CM adapter utilizes a level-shifting technique to shift the input common mode voltage of 0-1 V to the level below 0.1 V. By introducing this circuit as the front-end block of the proposed op-amp, the PMOS differential input stage can be operated appropriately with the rail-to-rail input common mode range. Second, the modified bandgap reference that combines two voltages with opposite temperature coefficients generates a temperature-insensitive bias current to the input stage. Besides, by the technique of cascading a diode with an additional BJT, the junction area of the original diodes can be reduced and in the actual application, fewer parallel-connected BJTs are needed. The two circuits are applied to the proposed op-amp operated at 1-V supply voltage in TSMC 1P4M 0.35μm CMOS technology. At 25℃, the dc gain is 78.9 dB and unity-gain bandwidth is 3.73 MHz. The phase margin is 42.9°. For the temperature from 0℃ to 75℃, the frequency response is temperature-insensitive and the dc gain variation is 2dB. The layout view of the proposed op-amp is also presented and the area is 0.2 mm2.

The first part which is low-voltage class-D audio amplifier is proposed in this thesis. The proposed class-D audio amplifier uses a low-voltage error amplifier, there are some advantages different from the traditional class-D audio amplifier. The advantages include low sensitive to noise and low-power dissipation. In this work, we utilize voltage-mode control with pulse-width modulation techniques. The error signal compares with a triangle wave signal to generate a switching-control wave. The output power stage which includes two power transistors is derived by the switching wave. The second-order low-pass filter is used to eliminate output high frequency component and recover original audio signal. The low-voltage class-D audio amplifier is implemented with a TSMC 0.18μm 1P6M CMOS process, and the chip area is 1.39 x 1.34 mm2 (with PADs). The second part introduces the design of fully differential class-D audio amplifier in this thesis. The concern is that how to develop the modulation of class-D audio amplifier with high power efficiency in this thesis. The traditional H-bridge class-D audio amplifier which shortcoming is big signal distortion is worse than the proposed. However, the proposed circuit improves the drawback and makes high power efficiency at the same time. The circuit is implemented by a modified scheme of the pulse-width modulation. We have observed that, the increase of total harmonic distortion is due to non-linearity in the triangle wave. For overcoming this problem, negative feedback is adopted to reduce the total harmonic distortion. The fully differential class-D audio amplifier is implemented with a TSMC 0.35μm 2P4M CMOS process, and the chip area is 2.57 x 2.57 mm2 (with PADs).

Taiwan High Speed Rail (THSR) has proposed NT$500 Billion on BOT Rail Transportation System which makes it the first and ever highest budget in the world of its kind. Furthermore, THSR adopt the Slab Track Rail Transportation System with speed over 300 km per hour (Km/Hr) which will only take 90 minutes from Taipei to Kao-hsiung with the total distance of 345 km; this makes Taiwan a metropolis throughout entire island. The major structures of the Slab Track System include roadbed, stopper, cement asphalt, tract slab,rail,railslab and fastener. The advantages of the Slab Track System possess high capacity, high speed,on-time, weather resistance, higher safety and maintenance free. However, THSR has limited knowledge and experience on the Slab Track System imported from Japan, so it is extremely important to establish systematic database and expertise at this field. This thesis is focus on THSR’s building material, construction techniques, machinery and variety skills in reference of Shinkansen in Japan and also detail discussed on construction of concrete bed for sustaining rail. The content include following subjects: quality control of sustaining rail, job-site prefabrication slab inspection techniques, flexible supporting material under pre-cast rail slab, the quality of CA ( cement asphalt) and the features of high speed rail system. This thesis has also made recommendations on human resource distribution of rail slab construction. I truly expect this thesis can serve any practice reference in construction of data collection and construction techniques. Key words: high-speed rail transportation , slab track, flexible supporting material, CA (cement asphalt) mortar

Safe, high speed, on time, high transport volume, minimum land use, low energy and low pollution are unique features of high-speed rail transport. In countries reaching a threshold level of economic development, traditional railway system will no longer satisfy the need of the mass in cross-township transport. As the cost of energy and demand for environmental protection escalates, high-speed rails have gradually surfaced as a competitive mode of transport in cross-township traveling. Furthermore, it is able to bring regional developments. However, high-speed rail transport is a new industry in Taiwan. There has been no hands-on experience in the passenger service. How then, through the development of marketing strategy and implementation, so as to promote the service quality and customer satisfaction, has been a primary operations objective of high-speed railways. This motivated the need to study the service marketing strategy in high-speed rail transport. The Taiwan High Speed Rail Corporation (THSRC) is the subject of this study. The 7P marketing mix of the service industry was the theoretical foundation. Historical data on the service and marketing strategies of high-speed railways in countries such as Japan, France and Germany were collected. Questions for conducting in-depth interviews with experts in high-speed railway were devised from the study of these historical data. In addition, a survey questionnaire was developed from the data collected via interviews. Passengers taking the Taiwan High Speed Rail were surveyed for statistical analysis. Finally, an appropriate service and marketing strategy was developed. The results show, the Taiwan High Speed Rail needs to first build a brand image of safety and credibility. It needs to schedule and allocate headways in line with its target passenger group and develop a comprehensive product strategy for its target customers. Having done that, it needs to propose competitive price strategies and promotion programs on corporate customers and travel agencies. Making use of the comprehensive mobile telephony coverage and internet network, and more convenient channels should be further developed. Furthermore, the THSRC needs to solve the problem of passenger transfers in station areas gradually. This is necessary to promote the overall service quality, satisfy divergent needs of the target market, and build up a recognized brand in high-speed railway transport. Finally, the recommendations made to THSRC were compared with service and marketing strategies in other countries. It is hoped that the results would be able to provide THSRC and any other countries planning to develop high-speed railway, some practical reference in planning their marketing strategies.

Nowadays, the management and allocation for Taiwan Rail seats are still being done by the experiences of working staff, the seats usually allocated to some long-haul trips. This kind of method can not deal with the existing randomly distributed demand pattern. These results cause many empty seats, however, some of passengers were rejected to get seats in advance or only could buy tickets for standing seats. At the moment, The high speed rail ( HSR )system in Taiwan is being planned to build in the next seven years. In order to avoid the above-mentioned problems we are facing when the HSR will operate, and to fully utilize the seat resources of HSR, so that it is important to reflect the travel dynamic demand and thereby to increase the total revenue, It is clear that we have to take it into consideration about the management of seat allocation in the near future.In this research we assume the operation schedules have been known and about ten high speed trains are dispatched in a peak hour under different stopping schedule (the express service and skip-stop services )to discuss the allocation of HSR seats. The seat allocation model is established by two level type. The first level model (seat allocation model)divides seats into assignment seats and free seats. Using fuzzy multiobjective programming , we have two objectives of maximum revenue and minimum total stopping time loss based on trip distribution of forecasting demand under different schedules and train stopping schedules, so that it can allocate suitable number of seats to every train stations. The second level model uses computer system simulation method to simulate actual dynamic demand, so that it can decide the near-optimal number of seats to adjust and modify the first level model''s results. Finally, this research creates the fast inquiry database for seat allocation data, then it will become the useful tool for HSR seat management.

Taking Taiwan High Speed Rail as an example, we apply Arena method, including six patterns of stops, to simulate train operations for the purposes of preliminary schedule planning. In the basic train operation model, this research applies “express pre-emption” and “conditional waiting” as the starting point where it incorporates the method “Two lines and one way simulation” in the simulation process. Given that, we are able to derive two initial operation schedules: “Express preemption” and “conditional waiting” and formulate “emergency schedule” which leads to the completion of “contingency simulation model”. Whenever a delay occurs, for instance, our model can simultaneously generate emergency schedule to overcome the problem. This research also extends to include analysis of delayed time by irregular accident, and the number of affected trains. In terms of setting the accident conditions, this research experimented different accident time, location, degree of seriousness, and formulate appropriate irregular timetable to cope with the conditions. This allowed us to do in-depth analysis on the delayed time from each accident and the influence to our model. When an accident occurs, the operation system creates inefficiency in waiting time, and often canceling trains may mitigate such problems. On the other hand, either on “express preemption” or “conditional waiting” situation, if the leading train reaches station within acceptable margin of error in time, we can relax some condition on our model to allow the following train to speed up its schedule and reduce the waiting time of the whole system. This research provides a model that is capable of generating new timetable when an irregular event occurs. We expect this to raise passenger safety, service quality and leads to positive long-term prospects for Taiwan High Speed Rail operations.

Full textThis thesis presents an application to deal with the introduction of containerized cargo on the high-speed rail line operations between Lisbon and Madrid. The future rail line is a large, rigid and complex system with a long cycle of operation. Therefore, initial design needs to be carefully planned since once it’s installed it is very difficult and expensive to modify. In order to plan the infrastructure, its life cycle performance needs to be considered, given that the performance of the infrastructure depends not only on the initial project preparation and design but also on the maintenance and renewal decisions taken during the life cycle. In addition, in order to guarantee an optimal long-term result for the railway system, the effects of decisions taken should be methodically evaluated. Therefore, it is mandatory that all options (pre and post-operation) are evaluated in order to better serve demand and improve cargo investment efficiency. For different reasons until now, cargo was never a target revenue segment considered for high-speed rail lines development. The main reasons for this are the serious maintenance and operational constraints that occur when conventional freight-rail trains are ridded in a high-speed rail line, namely in terms of the track maintenance rehabilitation and safety for passengers. The current research aims to study the inclusion of ‘light rail-freight’ service on the Lisbon-Madrid high-speed rail connection in the investment evaluation through the use of dedicated rolling stock to deliver cargo. The expectation is to handle the extra capacity of the line derived from the passenger’s demand for introducing cargo services, aiming at a better efficiency for the investment. The analysis takes the passenger and cargo operations into consideration as well as all the impacts on the several potential stakeholders such as government, infrastructure manager, operator, other transport modes operators and society. This brings a multi-dimension into the decision process turning the analysis more complex but also more comprehensive. Stakeholders typically have different objectives and concerns. Their perspective and commitment to project varies according to these objectives and concerns. Thus, solutions need to find a compromising platform between those stakeholders in order to become implementable. As a result, a more comprehensive multi-stakeholder method is preferably used, instead a traditional cost-benefit approach. The feasibility of this method, called MATE – Multi-Attribute Tradespace Exploration, for dealing with this complex transportation issues and associated constraints is discussed and the result is positive, not only for the problem addressed but also for the recognition of its potential to be applicable to other transportation domains. If one takes into consideration that rail-cargo activity should integrate a rail-road facility in order to turn the service commercially viable, results show the ability of the investment to integrate cargo trains in the daily routine of the line evaluated.
A presente tese apresenta uma aplicação metodológica que lida com a introdução de carga contentorizada na operação da linha ferroviária de alta-velocidade entre Lisboa e Madrid. A futura linha ferroviária é representada por um grande e complexo sistema de transporte com um longo ciclo de operações. O planeamento eficaz da infraestrutura considera o desempenho do seu ciclo de vida, dado que o desempenho da infraestrutura não depende apenas do projeto inicial mas também das decisões de manutenção e renovação tomadas durante o ciclo de vida da infraestrutura. Além disso, a fim de garantir um resultado ótimo para o sistema ferroviário implementado, estas decisões deverão ser tomadas e avaliadas de forma metódica. Desde modo, é obrigatório que todas as opções (pré e pós-operação) sejam avaliadas, de forma a servir eficazmente a procura de passageiros e melhorar a eficácia do investimento de carga. Por diferentes motivos, a introdução de carga em linhas de alta-velocidade não tem sido uma opção de investimento nos diferentes sistemas de alta-velocidade implementados. Os principais motivos centram-se com os custos de operação, manutenção e as restrições operacionais que decorrem da circulação destas composições, nomeadamente em termos de reabilitação da via e segurança para os passageiros. A presente investigação tem como objetivo a introdução de mercadorias ‘leves’ na ligação de alta-velocidade entre Lisboa e Madrid e a avaliação do investimento necessário para o transporte de carga com recurso a material circulante dedicado. A expectativa é utilizar o espaço deixado pela operação de passageiros, para a introdução dos serviços de carga, de forma a melhorar/otimizar a eficiência do investimento. A análise leva em consideração as operações de passageiros e carga, bem como os impactos sobre os potenciais grupos de interessados selecionados, tais como o Estado, o Gerente da Infraestrutura, operadores e a sociedade em geral, integrando-os numa análise muti-dimensional. Os grupos de interessados selecionados têm, por norma, diferentes objetivos e interesses em relação à avaliação que fazem do investimento em análise. A sua perspetiva e ação de compromisso variam em relação a estes objetivos e preocupações. Assim, as soluções necessitam de encontrar um ponto de compromisso entre as diferentes partes interessadas, de forma a tornarem-se exequíveis. Como resultado, é apresentado um método multi-decisor mais abrangente do que as tradicionais abordagens Custo-benefício. A viabilidade do método MATE - Multi-Attribute Tradespace Exploration, para lidar com questões relativas a sistemas de transporte complexos, é aqui discutida e os resultados demonstram a capacidade para lidar não só com o problema abordado mas também o reconhecimento para lidar com outros domínios de transporte. Os resultados consideram um investimento em instalações de apoio rodoferroviário (plataforma logísticas) de forma a tornar comercialmente viável o serviço de transporte de carga e demonstram a capacidade do investimento para integrar o serviço de carga na rotina diária da operação da linha Lisboa-Madrid.

A low-power high-gain CMOS operational amplifier with rail-to-rail input/output ranges is presented in this paper. A constant-gm controller is employed in the input stage to achieve an optimum bandwidth and settling response in a wide operational range. A differential-input single-output gain-boosting amplifier without common-mode feedback is applied to minimize the power consumption and increase the dc gain of opamp. The floating current sources are also introduced to the cascode stage to provide proper bias levels for the class AB output stage. The proposed opamp can load with a large capacitance or a small resistance loads without losing the gain and unity-gain bandwidth. It has been fabricated in a 0.35 μm 2P4M CMOS process. With a 50 pF of the output capacitance load, a 123dB of dc gain and a 1.52MHz of unity-gain frequency can be achieved in the proposed opamp. The total power dissipation is only 0.36 mW at a 3.3 V of supply voltage.

High-speed railway is the development direction of modern railway, high-speed railway abroad has many years of development history, and our country is now in the beginning of high-speed railway research and development. Due to the fast speed of high-speed railway, once found obstacle suddenly appears in front of the train, it is difficult to take contingency measures, effectively prevent accidents from occurring. Therefore, in the design, construction and operation management process, accident prevention system to be fully considered and enough visual is very important. This study will through the high speed railway accident related literature discussion, case review of foreign high speed railway accidents and domestic railway accident, identifying the cause of the disaster through expert interview, questionnaire survey and AHP analysis method to achieve the optimal scheme of accident prevention. In this research, we put forward some countermeasures and preventive measures in the aspects of train system, track system and accident prevention system. After the AHP analytic hierarchy process, the best method is accident prevention system.

Latent class model has been widely used in many fields. Past studies mostly used the latent class model with the multinomial logit formulation to explore market segmentation. In the existing literature, two types of the latent class nested logit models have been developed to relax the independence of irrelevant alternatives property that imposes the restriction on the multinomial logit. This study aims to apply and compare two alternative latent class nested logit models to examine market segmentation of access modes for high speed rail. The result shows that the latent class nested logit model that is not fully consistent with utility maximization has a higher goodness-of-fit than the latent class nested logit model that is fully consistent with utility maximization. The nested logit models indicate that shuttle bus shares the common unobserved component with city bus and train and these access modes are highly substituted. The study suggests the shuttle bus should have good service quality in order to attract high speed rail passengers to use this access mode.

As the safe, reliable, comfortable and high-speed passenger rail is expected to contribute significantly to intercity passenger travel, lack of good access or egress transport services at Taiwan HSR stations may create potential problems. The objectives of this research are to develop disaggregate mode choice models that can identify important variables influencing the choice of HSR egress modes, and to propose strategies for improvement of accessibility to HSR stations. Because the Taiwan HSR is not yet available, the stated preference approach was applied to collect data on behavioral response to egress modes. The empirical results of the multinomial logit and nested logit choice models reveal that egress time, egress cost, personal income, number of baggage, and pay or reimburse travel expense are significant variables associated with the choice of HSR egress modes. The planned or new egress mode services, such as rapid transit systems and rail branch lines, can attract significant proportions of potentail HSR travelers. Respondents are more sensitive to the changes in egress time than egress cost, especially for public modes of transportation. Suggestions on improvements of HSR access or egress mode services are proposed.

Service design is one of most importation tasks in the strategic and tactical planning process for a Taiwan high-speed rail (HSR) operator. The design of passenger train services is generally considered with the regular interval, or periodic timetable. In a fixed interval (e.g. in one hour), service plan decisions are selections of stop pattern and service frequency. In a service plan, passengers of different origin-destination may take the same train together. One passenger’s choice is dependent on other passenger’s choices, when seating capacity and crowding effect are considers. Therefore, we need a passenger’s choice model to estimate the demand of each type of train service with the fixed O/D demand, or the passenger’s response to a specific service plan. In order to design a good service plan, the knowledge of passenger’s choice of train service is essential. Therefore, this research includes three parts. In the first part, the study focuses on the discussion of train demand issues and some passenger’s choice modeling techniques of train service. The passenger’s choice of train service in the model is a route choice problem with a train service network and a generalized cost function. The generalized cost includes in-vehicle travel time, access/egress travel time, waiting and transfer time, fare, and the discomfort index for the crowding in the train. The discomfort index is a flow-dependent variable, that is, its value is dependent on the number of passengers in the train. The passenger’s choice behavior can be formulated as a deterministic user equilibrium problem and a stochastic logit choice problem. It follows that; many available traffic assignment techniques can be applied to investigating such a route choice problem. Secondly, The study presents a modeling framework for solving the service plan problem of Taiwan high-speed rail. The framework explicitly considers both the Passenger’s and the operator’s viewpoints in a bi-level program. The passenger’s choice model is the lower level problem in the bi-level program. The upper-level problem is an operator’s model for choosing the stop pattern and frequency of train service, with the constraints of line capacity, fleet size, and so on. The iterative sensitivity-based algorithm solves the bi-level programming problem. The lower level problem and the upper level problem are solved iteratively each iteration. When the low level problem is solved, the sensitivity of the upper level decision variable results in a function of lower level flow variables. The sensitivity function will then be used in solving the upper level problem. At last, a numerical example will show the function and performance of the model for the service design problem of Taiwan high speed rail. Thirdly, The study presents a mathematical programming model for the train dispatch problem. The primary challenge in such a problem is to determine the appropriate time and location for each conflicting train to overtake another train. The purpose of the model is to construct an efficient train diagram and timetable for a realistic railway system. The model was tested with some examples of Taiwan high speed train service plan to show its function and effectiveness for the train dispatch problem.

High speed rail (HSR) system is under development on the west corridor Taiwan by a build-operate-transfer (BOT) Approach. The concession company, Taiwan HSR company will have 35 years to build and operate the HSR system and would consider maximum profit as its main objective. However, the government would like to achieve the maximum social welfare objective with the mega-BOT project. It is desirable to understand effects of different fare schemes on the two objectives. This research applies analytic optimization approach to analyze optimal fare of the HSR system with objectives of the maximization of operator profit and social welfare. The study considers a distance-based fare structure, while considering logit model as the basis of demand model. Variable and capital cost are all be included in the cost function with a distance-based cost allocation method. The result of this research could provide information with which the HSR company can ensure its profitability while the government can have more reasonable regulation on the HSR pricing mechanism.

This research presents both different sampling types for filtered multitone (FMT) system in the high speed rail environment. The FMT transmission system is a filter bank-based multicarrier technique that has characteristics of a high spectral containment and the subcarriers do not overlap each other, so intercarrier interference (ICI) sensitivity is low. In this paper, we use two different architectures: critical sampled and noncritical sampled techniques to design the system. In the FMT transmission system, although it need the equalizer to eliminate system itself generated intersymbol interference (ISI), but that can obtain a higher transmission capacity without too many sub-channels

According to the studies over 50 years, the phenomenon of gentrification has not only been found in Europe, North America or Oceania, but also all over the world. Since the beginning of 21st century, gentrification issues have been explored in a broader and more diverse meanings. After reviewing the literatures of gentrification and High-speed rail (HSR) station area development, there are a lot of clues suggesting that a certain relationship between HSR station area development and gentrification exits. Especially under the background of rapid growth of HSR network and urbanization in China, the HSR services should result in a lot of influences on local socioeconomic developments. However, there is still a lack of research on examining the development of HSR station areas from the perspective of gentrification. In this study, the areas surrounding two HSR stations, Hangzhou Station and Hangzhou East Station, which launched HSR services early in China, were selected as the empirical study areas. Because the local residents in Hangzhou East Station area is resettled on-site, the impact of HSR on the local residents would be insignificant. Therefore, this study focused on the employment changes within station areas and proposed the concept of “employment gentrification”. Totally 67,367 records of enterprises in the HSR station areas and the non-HSR station areas were collected as the study sample. According to education and income levels of the staffs, the enterprise observations are discriminated into high/low groups. By applying the survival analysis methods, this study compared the survival risks of high/low group enterprises in HSR station areas and non-HSR station areas to clarify the relationship between HSR developments and employment gentrification. The research results show that the employment gentrification happened in Hangzhou Station area (inner city area); however, there is no evidence supporting the employment gentrification in Hangzhou East Station area (outer city area). Academically, this study supplements the knowledge of the relationship between rail transit developments and gentrification. Meanwhile, this study indicates the possible reasons why inner and outer city areas show different results of employment gentrification and notes the possible different manifestations between employment and residential gentrification induced by rail transit systems. Practically, the empirical results of this research suggest that governments and enterprises should adopt different policies in inner and outer city areas according to the development stages of HSR station areas to reduce the problems of space-mismatching between employment and residence caused by employment gentrification.

One of the key techniques of electric vehicles (EVs) is battery management systems, which demand the development of battery modules, the measurement circuits of batteries, and so on. This thesis investigates a high-voltage operational amplifier with rail-to-rail input and output ranges, and an 8:1 analog high-voltage multiplexer for the battery voltage measurement. This thesis proposes a high-voltage operational amplifier with rail-to-rail input and output ranges to meet the required amplifier for the aforementioned technology. It also carries out the signal transfer circuit design for battery management systems, such as subtractor, analog to digital converter. Since the input range of the design could be up to 30 V, and the output range is 0 ∼ 29.57 V, ADC with a high input range is no longer needed hereby. Although the dc gain is 41 dB, the gain error can be corrected by using low-bit ADCs. Finally, this design is expected for battery management systems to attain accurate SOC estimation . Another key circuit is the high-voltage multiplexer. This thesis proposes a 8:1 highvoltage analog multiplexer which can be used to measure the voltage of a single cell in a battery string. If the battery modules consists of eight batteries connected in series and the voltage of a battery cell is 2.5 V to 4.5 V, the input voltage range is 0 ∼ 36 V. To resolve the high input voltage problem, this thesis demonstrates a 8:1 high-voltage analog multiplexer, where the output voltage range is in line with SAR ADC input voltage range of 1.5 ∼ 3.5 V.
