    Under NASA program NNA16BD84C, new architectures were identified and developed for supporting reliable and secure Communications, Navigation and Surveillance (CNS) needs for Unmanned Air Systems (UAS) operating in both controlled and uncontrolled airspace. An analysis of architectures for the two categories of airspace and an implementation technology readiness analysis were performed. These studies produced NASA reports that have been made available in the public domain and have been briefed in previous conferences. We now consider how the products of the study are influencing emerging directions in the aviation standards communities. The International Civil Aviation Organization (ICAO) Communications Panel (CP), Working Group I (WG-I) is currently developing a communications network architecture known as the Aeronautical Telecommunications Network with Internet Protocol Services (ATN/IPS). The target use case for this service is secure and reliable Air Traffic Management (ATM) for manned aircraft operating in controlled airspace. However, the work is more and more also considering the emerging class of airspace users known as Remotely Piloted Aircraft Systems (RPAS), which refers to certain UAS classes. In addition, two Special Committees (SCs) in the Radio Technical Commission for Aeronautics (RTCA) are developing Minimum Aviation System Performance Standards (MASPS) and Minimum Operational Performance Standards (MOPS) for UAS. RTCA SC-223 is investigating an Internet Protocol Suite (IPS) and AeroMACS aviation data link for interoperable (INTEROP) UAS communications. Meanwhile, RTCA SC-228 is working to develop Detect And Avoid (DAA) equipment and a Command and Control (C2) Data Link MOPS establishing LBand and C-Band solutions. These RTCA Special Committees along with ICAO CP WG/I are therefore overlapping in terms of the Communication, Navigation and Surveillance (CNS) alternatives they are seeking to provide for an integrated manned- and unmanned air traffic management service as well as remote pilot command and control. This paper presents UAS CNS architecture concepts developed under the NASA program that apply to all three of the aforementioned committees. It discusses the similarities and differences in the problem spaces under consideration in each committee, and considers the application of a common set of CNS alternatives that can be widely applied. As the works of these committees progress, it is clear that the overlap will need to be addressed to ensure a consistent and safe framework for worldwide aviation. In this study, we discuss similarities and differences in the various operational models and show how the CNS architectures developed under the NASA program apply

    The paper presents an Autonomous Electric Vehicle with obstacle avoidance system. This research work made use of ultrasonic sensors, the principle of distance measurements and calculations as well as detecting obstacle on its path. The device consists of three ultrasonic sensors that detect object for each left, right and front of the vehicle, based on developed and installed codes in the Arduino microcontroller and displays the range using ISIS Proteus 8 electronic modelling software. The minimum and maximum range of object detections is 2cm to 400cm respectively. However, the measured distance was from 25cm to 150cm and the corresponding calculated distances using oscilloscope waveforms are 28.10cm and 148.3cm. The difference between the measured and calculated distance was 5.4% on average. GPS navigates the vehicle autonomously to its destination using an algorithm for navigation based on reactive behavior. The vehicle is powered by rechargeable batteries (4 lithium ion batteries) which are charged using external power source by connecting into electricity grid. Furthermore, a solar panel has been utilized as a secondary source of power to charge the batteries. This reduces the dependency of the vehicle on external power sources. The vehicle is capable of moving for about 20m to and fro and avoiding obstacle on its path

They superimpose safety-critical information on top of the drivers forward field of view and thereby help drivers keep their eyes forward while driving. Since the first introduction about three decades ago, automotive HUDs have been available in various commercial vehicles. Despite the long history and potential benefits of automotive HUDs, however, the design of useful automotive HUDs remains a challenging problem. In an effort to contribute to the design of useful automotive HUDs, this doctoral dissertation research conducted four studies. In Study 1, the functional requirements of automotive HUDs were investigated by reviewing the major automakers' automotive HUD products, academic research studies that proposed various automotive HUD functions, and previous research studies that surveyed drivers HUD information needs. The review results indicated that: 1) the existing commercial HUDs perform largely the same functions as the conventional in-vehicle displays, 2) past research studies proposed various HUD functions for improving driver situation awareness and driving safety, 3) autonomous driving and other new technologies are giving rise to new HUD information, and 4) little research is currently available on HUD users perceived information needs. Based on the review results, this study provides insights into the functional requirements of automotive HUDs and also suggests some future research directions for automotive HUD design. In Study 2, the interface design of automotive HUDs for communicating safety-related information was examined by reviewing the existing commercial HUDs and display concepts proposed by academic research studies. Each display was analyzed in terms of its functions, behaviors and structure. Also, related human factors display design principles, and, empirical findings on the effects of interface design decisions were reviewed when information was available. The results indicated that: 1) information characteristics suitable for the contact-analog and unregistered display formats, respectively, are still largely unknown, 2) new types of displays could be developed by combining or mixing existing displays or display elements at both the information and interface element levels, and 3) the human factors display principles need to be used properly according to the situation and only to the extent that the resulting display respects the limitations of the human information processing, and achieving balance among the principles is important to an effective design. On the basis of the review results, this review suggests design possibilities and future research directions on the interface design of safety-related automotive HUD systems. In Study 3, automotive HUD-based take-over request (TOR) displays were developed and evaluated in terms of drivers take-over performance and visual scanning behavior in a highly automated driving situation. Four different types of TOR displays were comparatively evaluated through a driving simulator study - they were: Baseline (an auditory beeping alert), Mini-map, Arrow, and Mini-map-and-Arrow. Baseline simply alerts an imminent take-over, and was always included when the other three displays were provided. Mini-map provides situational information. Arrow presents the action direction information for the take-over. Mini-map-and-Arrow provides the action direction together with the relevant situational information. This study also investigated the relationship between drivers initial trust in the TOR displays and take-over and visual scanning behavior. The results indicated that providing a combination of machine-made decision and situational information, such as Mini-map-and-Arrow, yielded the best results overall in the take-over scenario. Also, drivers initial trust in the TOR displays was found to have significant associations with the take-over and visual behavior of drivers. The higher trust group primarily relied on the proposed TOR displays, while the lower trust group tended to more check the situational information through the traditional displays, such as side-view or rear-view mirrors. In Study 4, the effect of interactive HUD imagery location on driving and secondary task performance, driver distraction, preference, and workload associated with use of scrolling list while driving were investigated. A total of nine HUD imagery locations of full-windshield were examined through a driving simulator study. The results indicated the HUD imagery location affected all the dependent measures, that is, driving and task performance, drivers visual distraction, preference and workload. Considering both objective and subjective evaluations, interactive HUDs should be placed near the driver's line of sight, especially near the left-bottom on the windshield.์ž๋™์ฐจ ํ—ค๋“œ์—…

    This thesis intended to provide a holistic vision on the potential consequences of the introduction of emerging electrical Vertical Takeoff and Landing (e VTOL) Personal Air Transportation System (PATS) to contribute to the forming of public and policy opinion, and to assess the impacts and the feasibility of that. Instead of looking from a detailed vehicle design viewpoint, we tried to understand the need, the impacts, and the perceptions and the concerns of stakeholders. Thus, it was set a framework and methodology starting with a technology assessment point of view in the light of transportation system analysis. Limitations of the current ground and airline transportation systems, increasing congestion, poor block speed, combined with expanding population and demand for affordable on- demand mobility are driving the development of future transportation technology and policy. The third wave of aeronautics might be the answer and could bring about great new capabilities for society that would bring aviation into a new age of being relevant in daily lives since eVTOL PATS is envisioned as the next logical step in the natural progression in the history of disruptive transportation system innovations. However, there are a lot of questions. Although there was difficulty since the system was an emerging air transportation mode, an interdisciplinary study has been conducted to assess the impacts of developing such a capability. The research questions were determined to address the research objectives. What is the current state of mobility and eVTOL air transportation mode? What are the potential benefits of eVTOL air transportation mode for user and society? What are the perceptions of service providers, regulator, and user? What are the main challenges including technology, regulation, operation, social and environment aspects to enable the system? What are the enabling technologies? Nevertheless, with the results obtained lately from the research activities, revolutionary technologies and regulations are bringing us closer to eVTOL PATS reality every day. It can be argued that a new socio-technical transition will come about like the transition from horse drawn carriers to cars. Even if it is still a long way to go, it seems rather likely that the time has been arriving in the next decade. Their existence and operation would therefore need to be taken into consideration for todayโ€™s planning considerations and construction projects to be able to have this emerging air transportation mode available in the future. As the technology underlying eVTOL PATS evolves, wider eVTOL adoption across various markets is likely to be supported further if a set of key challenges such as safety and security, ease of use and autonomy, noise, infrastructure, and air traffic management are overcome. Achieving drastic improvements in ease of use, safety and community acceptable noise are the most critical steps towards the future feasibility of this market. Multi-use demos and demonstrating successful operation with early vehicles, namely eVTOL PATS prototype field operations, will create public acceptance and understanding of potentials in emerging air transportation mode for public good, use and learn in multiple applications. The overall perception of the user, service provider and regulator are positive, and the support is high. Shortly, a successful implementation and sustainable transition will depend on overcoming technological hurdles, regulatory frameworks, operational safety, cost competitiveness, and sensibilities of the affected communities. There is a need to enable people and goods to have the convenience of on-demand, point-to-point safe travel, further, anywhere in less travel time, through a network of pocket airports/vertiports, and there is a significant potential benefit so that policy makers, regulators and metropolesโ€™ transportation planning departments should consider an inclusion of eVTOL air transportation mode into the scenarios and policies of the future.Esta tese pretende fornecer uma visรฃo holรญstica sobre as potenciais consequรชncias da introduรงรฃo do Sistema de Transporte Aรฉreo Pessoal (PATS) de Decolagem e Pouso Vertical elรฉtrico emergente (e VTOL) para contribuir para a formaรงรฃo de opiniรฃo pรบblica e polรญtica, e para avaliar os impactos e a viabilidade disso. Em vez de olhar de um ponto de vista detalhado o projeto do veรญculo, tentamos entender a necessidade, os impactos, as percepรงรตes e as preocupaรงรตes das partes interessadas. Assim, foi definido um quadro e uma metodologia partindo de um ponto de vista de avaliaรงรฃo de tecnologia ร  luz da anรกlise do sistema de transporte. As limitaรงรตes dos atuais sistemas de transporte terrestre e aรฉreo, o aumento do congestionamento, a baixa velocidade do trรกfego, combinados com a expansรฃo da populaรงรฃo e a mobilidade com procura acessรญvel estรฃo impulsionando o desenvolvimento de futuras tecnologias e polรญticas de transporte. A terceira onda da aeronรกutica pode ser a resposta e pode trazer grandes novas capacidades para a sociedade que trariam a aviaรงรฃo para uma nova era de ser relevante na vida cotidiana, uma vez que o VTOL PATS รฉ visto como o prรณximo passo lรณgico na progressรฃo natural na histรณria das inovaรงรตes disruptivas do sistema de transporte. No entanto, hรก muitas perguntas. Embora tenha havido dificuldade por se tratar de um modo de transporte aรฉreo emergente, um estudo interdisciplinar foi realizado para avaliar os impactos do desenvolvimento de tal capacidade. As questรตes de investigaรงรฃo foram determinadas para atender aos objetivos do projeto. Qual รฉ o estado atual da mobilidade e do modo de transporte aรฉreo eVTOL? Quais sรฃo os benefรญcios potenciais do modo de transporte aรฉreo eVTOL para o utilizador e a sociedade? Quais sรฃo as percepรงรตes dos provedores de serviรงos, regulador e utilizador? Quais sรฃo os principais desafios, incluindo tecnologia, regulamentaรงรฃo, operaรงรฃo, aspectos sociais e ambientais para habilitar o sistema? Quais sรฃo as tecnologias facilitadoras? No entanto, com os resultados obtidos ultimamente nas atividades de pesquisa, tecnologias e regulamentaรงรตes revolucionรกrias estรฃo nos aproximando cada dia mais da realidade do VTOL PATS. Pode-se argumentar que uma nova transiรงรฃo sรณcio-tรฉcnica ocorrerรก como a transiรงรฃo de carruagens puxadas por cavalos para automรณveis. Mesmo que ainda seja um longo caminho a percorrer, parece bastante provรกvel que a hora esteja chegando na prรณxima dรฉcada. A sua existรชncia e operaรงรฃo, portanto, precisam ser levadas em consideraรงรฃo para as questรตes de planeamento e projetos de construรงรฃo de hoje para poder ter esse modo de transporte aรฉreo emergente disponรญvel no futuro. ร€ medida que a tecnologia subjacente ao eVTOL PATS evolui, รฉ provรกvel que a adoรงรฃo mais ampla do eVTOL em vรกrios mercados seja ainda mais apoiada se um conjunto de desafios importantes, como seguranรงa e proteรงรฃo, facilidade de uso e autonomia, ruรญdo, infraestrutura e gestรฃo de trรกfego aรฉreo forem superados. Alcanรงar melhorias drรกsticas na facilidade de uso, seguranรงa e ruรญdo aceitรกvel pela comunidade sรฃo os passos mais crรญticos para a viabilidade futura deste mercado. Demonstraรงรตes multi-uso e demonstraรงรฃo de operaรงรฃo bem- sucedida com veรญculos iniciais, ou seja, operaรงรตes de campo do protรณtipo eVTOL PATS, criarรฃo aceitaรงรฃo pรบblica e compreensรฃo dos potenciais no modo de transporte aรฉreo emergente para o bem pรบblico, uso e aprendizado em vรกrias aplicaรงรตes. A percepรงรฃo geral do utilizador, prestador de serviรงo e regulador รฉ positiva, e o suporte รฉ alto. Uma implementaรงรฃo bem-sucedida e uma transiรงรฃo sustentรกvel dependerรก da superaรงรฃo de obstรกculos tecnolรณgicos, estruturas regulatรณrias, seguranรงa operacional, competitividade de custos e sensibilidade das comunidades afetadas. Hรก uma necessidade de permitir que pessoas e mercadorias tenham a conveniรชncia de viagens seguras de que necessitam, ponto a ponto, e alรฉm disso, em qualquer lugar em menos tempo de viagem. Isso pode ser feito por meio de uma rede de aeroportos/vertiports, e hรก um benefรญcio potencial significativo para que os formuladores de polรญticas, reguladores e departamentos de planeamento de transporte das grandes metrรณpoles considerem a inclusรฃo do modo de transporte aรฉreo eVTOL nos cenรกrios e polรญticas do futuro

Additional studies, however, are insufficient. In particular, automated driving vehicles do not need human driving, so unlike conventional vehicles, the drivers obtain the freedom to do other activities inside the vehicle. The aim of this paper is to collect previous research data and to predict and analyze various activities expected from the passengers of automated driving vehicles. Also, this paper investigates and analyzes the functions and arrangements of passenger plane and ship seats, as well as the current vehicle seats. Then, it proposes the functions and features of seats required by automated driving vehicles. In addition, it checks the validity of the predictions by comparing them with automated driving concept vehicles submitted to motor shows and CES by the global automakers, the Tier1, and 2 automotive suppliers. Patents for applications, registrations, and prospective registrations were investigated to identify trends in automated driving vehicle seat technology. It also draws out what is different from the current vehicle seats in automated driving vehicle seats. It was intended to suggest the direction to move forward in the research and development of seats for automated driving vehicles. And this paper not only proposed the function and features of seats of automated driving vehicles that have not yet been commercialized, but also considered possible problems during commercialization and suggested solutions to them. The upcoming automated driving vehicle regulation trends have been investigated to confirm the validity of this paper. Based on this, additional studies needed for commercialization of automated driving vehicles were considered.์ž์œจ์ฃผํ–‰์ฐจ์˜ ์ƒ์šฉํ™”๋ฅผ ์œ„ํ•ด์„œ ์ง์ ‘์ ์œผ๋กœ ์—ฐ๊ด€๋œ ๊ธฐ์ˆ ๊ณผ ๊ด€๋ จ ๋ฒ•๊ทœ ์ œ์ •์— ๊ด€ํ•œ ์—ฐ๊ตฌ๋Š” ๋งŽ์ด ์ง„ํ–‰๋˜๊ณ  ์žˆ๋‹ค. ํ•˜์ง€๋งŒ ๊ทธ ์™ธ์— ๋ถ€์ˆ˜์ ์ธ ์—ฐ๊ตฌ๋“ค์€ ๋ฏธํกํ•œ ์‹ค์ •์ด๋‹ค. ํŠนํžˆ ์ž์œจ์ฃผํ–‰์ฐจ๋Š” ์ธ๊ฐ„์ด ์ง์ ‘ ์šด์ „์„ ํ•  ํ•„์š”๊ฐ€ ์—†๊ธฐ ๋•Œ๋ฌธ์— ๊ธฐ์กด์˜ ์ฐจ์™€๋Š” ๋‹ค๋ฅด๊ฒŒ ์‹ค๋‚ด์—์„œ ๋‹ค์–‘ํ•œ ํ™œ๋™๋“ค์„ ํ•  ๊ฒƒ์œผ๋กœ ์˜ˆ์ƒํ•˜๊ณ  ์žˆ๋‹ค. ๋”ฐ๋ผ์„œ ๊ธฐ์กด ์—ฐ๊ตฌ์ž๋ฃŒ๋“ค์„ ์ˆ˜์ง‘ํ•˜์—ฌ ์ž์œจ์ฃผํ–‰์ฐจ ์—์„œ ๊ธฐ๋Œ€๋˜๋Š” ์Šน๊ฐ๋“ค์˜ ๋‹ค์–‘ํ•œ ํ™œ๋™๋“ค์— ๋Œ€ํ•˜์—ฌ ์˜ˆ์ธกํ•˜์—ฌ ๋ณด๊ณ , ํ˜„์žฌ ์ฐจ๋Ÿ‰์šฉ ์‹œํŠธ๋งŒ์ด ์•„๋‹ˆ๋ผ ์—ฌ๊ฐ๊ธฐ์™€ ์—ฌ๊ฐ์„ ์˜ ์‹œํŠธ๋“ค์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์กฐ์‚ฌํ•˜๊ณ  ๋ถ„์„ํ•˜์—ฌ, ์ž์œจ์ฃผํ–‰์ฐจ์—์„œ ํ•„์š”ํ•œ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์ œ์•ˆํ•˜๊ณ ์ž ํ•œ๋‹ค. ๋˜ํ•œ ํ˜„์žฌ๊นŒ์ง€ ๋ชจํ„ฐ์‡ผ์™€ CES์— ์ถœํ’ˆ๋œ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ๋ถ„์„ํ•˜์—ฌ ๋…ผ๋ฌธ์—์„œ ์ œ์•ˆํ•œ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜์˜ ํƒ€๋‹น์„ฑ์„ ํ™•์ธํ•˜์—ฌ ๋ณด์•˜๊ณ , ํ˜„์žฌ๊นŒ์ง€ ์ถœ์› ๋ฐ ๋“ฑ๋ก๋œ ์ž์œจ์ฃผํ–‰์ฐจ ์‹œํŠธ ๊ด€๋ จ ํŠนํ—ˆ ์กฐ์‚ฌ๋ฅผ ํ†ตํ•˜์—ฌ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์—์„œ ๊ธฐ์กด ์ฐจ๋Ÿ‰์˜ ์‹œํŠธ์™€๋Š” ๋‹ค๋ฅด๊ฒŒ ์ค‘์ ์„ ๋‘๊ณ  ์žˆ๋Š” ๋ถ€๋ถ„์ด ๋ฌด์—‡์ธ์ง€๋ฅผ ํ™•์ธํ•ด๋ณด๊ณ  ์•ž์œผ๋กœ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ ์—ฐ๊ตฌ ๋ฐ ๊ฐœ๋ฐœ์—์„œ ๋‚˜์•„๊ฐ€์•ผํ•  ๋ฐฉํ–ฅ์„ ์ œ์‹œํ•˜๊ณ ์ž ํ•˜์˜€๋‹ค. ๊ทธ๋ฆฌ๊ณ  ๋ณธ ์—ฐ๊ตฌ๋Š” ์•„์ง ์ƒ์šฉํ™” ๋˜์ง€ ์•Š์€ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹œํŠธ์˜ ๊ธฐ๋Šฅ๊ณผ ๋ฐฐ์น˜๋ฅผ ์ œ์•ˆ์œผ๋กœ๋งŒ ๊ทธ์น˜์ง€์•Š๊ณ  ์ƒ์šฉํ™” ์‹œ์— ๋ฐœ์ƒํ•  ์ˆ˜ ์žˆ๋Š” ๋ฌธ์ œ์ ์— ๋Œ€ํ•ด์„œ๋„ ๊ณ ๋ฏผํ•˜๊ณ  ๊ทธ์— ๋Œ€ํ•œ ํ•ด๊ฒฐ๋ฐฉ์•ˆ์„ ์ œ์‹œํ•˜์˜€๋‹ค. ๋งˆ์ง€๋ง‰์œผ๋กœ ๋‹ค๊ฐ€์˜ค๋Š” ์ž์œจ์ฃผํ–‰์ฐจ์— ๋Œ€์‘ํ•œ ์ „์„ธ๊ณ„์˜ ์ฐจ๋Ÿ‰ ๋ฒ•๊ทœ ํŠธ๋žœ๋“œ๋ฅผ ์กฐ์‚ฌํ•˜์—ฌ ํ˜„์žฌ ์ฐจ๋Ÿ‰ ๋ฒ•๊ทœ์˜ ํ‹€์—์„œ๋Š” ๋ฒ—์–ด๋‚œ ๋ณธ ์—ฐ๊ตฌ์˜ ์ž์œจ์ฃผํ–‰์ฐจ์˜ ์‹ค๋‚ดํ™˜๊ฒฝ ๋ฐ ์‹œํŠธ๋ฅผ ์—ฐ๊ตฌ์˜ ํƒ€๋‹น์„ฑ์„ ํ™•์ธํ•˜์˜€์œผ๋ฉฐ, ์ด ํƒ€๋‹น์„ฑ์„ ๊ทผ๊ฑฐ๋กœ ์ž์œจ์ฃผํ–‰์ฐจ ์ƒ์šฉํ™”๋ฅผ ์œ„ํ•˜์—ฌ ํ–ฅํ›„ ํ•„์š”ํ•œ ์ถ”๊ฐ€ ์—ฐ๊ตฌ๋“ค์— ๋Œ€ํ•˜์—ฌ ๊ณ ๋ฏผํ•˜์—ฌ ๋ณด์•˜๋‹ค.Abstract i Contents iii List of Tables v List of Fugures vii 1.

    Risks, Safety and Security in the Ecosystem of Smart Cities

    Get PDF
    We have performed a review of systemic risks in smart cities dependent on intelligent and partly autonomous transport systems. Smart cities include concepts such as smart transportation/use of autonomous transportation systems (i.e., autonomous cars, subways, shipping, drones) and improved management of infrastructure (power and water supply). At the same time, this requires safe and resilient infrastructures and need for global collaboration. One challenge is some sort of risk based regulation of emergent vulnerabilities. In this paper we focus on emergent vulnerabilities and discussion of how mitigation can be organized and structured based on emergent and known scenarios cross boundaries. We regard a smart city as a software ecosystem (SEC), defined as a dynamic evolution of systems on top of a common technological platform offering a set of software solutions and services. Software ecosystems are increasingly being used to support critical tasks and operations. As a part of our work we have performed a systematic literature review of safety, security and resilience software ecosystems, in the period 2007โ€“2016. The perspective of software ecosystems has helped to identify and specify patterns of safety, security and resilience on a relevant abstraction level. Significant vulnerabilities and poor awareness of safety, security and resilience has been identified. Key actors that should increase their attention are vendors, regulators, insurance companies and the research community. There is a need to improve private-public partnership and to improve the learning loops between computer emergency teams, security information providers (SIP), regulators and vendors. There is a need to focus more on safety, security and resilience and to establish regulations of responsibilities on the vendors for liabilities
