    The excitement and promise generated by Urban Air Mobility (UAM) concepts have inspired both new entrants and large aerospace companies throughout the world to invest hundreds of millions in research and development of air vehicles, both piloted and unpiloted, to fulfill these dreams. The management and separation of all these new aircraft have received much less attention, however, and even though NASAs lead is advancing some promising concepts for Unmanned Aircraft Systems (UAS) Traffic Management (UTM), most operations today are limited to line of sight with the vehicle, airspace reservation and geofencing of individual flights. Various schemes have been proposed to control this new traffic, some modeled after conventional air traffic control and some proposing fully automatic management, either from a ground-based entity or carried out on board among the vehicles themselves. Previous work has examined vehicle-based traffic management in the very low altitude airspace within a metroplex called UTM airspace in which piloted traffic is rare. A management scheme was proposed in that work that takes advantage of the homogeneous nature of the traffic operating in UTM airspace. This paper expands that concept to include a traffic management plan usable at all altitudes desired for electric Vertical Takeoff and Landing urban and short-distance, inter-city transportation. The interactions with piloted aircraft operating under both visual and instrument flight rules are analyzed, and the role of Air Traffic Control services in the postulated mixed traffic environment is covered. Separation values that adapt to each type of traffic encounter are proposed, and the relationship between required airborne surveillance range and closure speed is given. Finally, realistic scenarios are presented illustrating how this concept can reliably handle the density and traffic mix that fully implemented and successful UAM operations would entail

    Last-mile delivery of goods has gained a lot of attraction during the COVID-19 pandemic. However, current package delivery processes often lead to parking in the second lane, which in turn has negative effects on the urban environment in which the deliveries take place, i.e., traffic congestion and safety issues for other road users. To tackle these challenges, an effective autonomous delivery system is required that guarantees efficient, flexible and safe delivery of goods. The project LogiSmile, co-funded by EIT Urban Mobility, pilots an autonomous delivery vehicle dubbed the Autonomous Hub Vehicle (AHV) that works in cooperation with a small autonomous robot called the Autonomous Delivery Device (ADD). With the two cooperating robots, the project LogiSmile aims to find a possible solution to the challenges of urban goods distribution in congested areas and to demonstrate the future of urban mobility. As a member of Nieders\"achsische Forschungszentrum f\"ur Fahrzeugtechnik (NFF), the Institute for Software and Systems Engineering (ISSE) developed an integrated software safety architecture for runtime monitoring of the AHV, with (1) a dependability cage (DC) used for the on-board monitoring of the AHV, and (2) a remote command control center (CCC) which enables the remote off-board supervision of a fleet of AHVs. The DC supervises the vehicle continuously and in case of any safety violation, it switches the nominal driving mode to degraded driving mode or fail-safe mode. Additionally, the CCC also manages the communication of the AHV with the ADD and provides fail-operational solutions for the AHV when it cannot handle complex situations autonomously. The runtime monitoring concept developed for the AHV has been demonstrated in 2022 in Hamburg. We report on the obtained results and on the lessons learned.Comment: 11 page

    Digital transformation makes the business environment increasingly competitive. Companies must follow this transformation to differentiate themselves and build a solid competitive position in the markets in which they operate. In this sense, it is crucial to recognize the importance of new technologies in improving logistics operations and the advantages that come with them. Among these technologies, autonomous vehicles stand out. Thus, this study attempts, on the one hand, to understand how autonomous vehicle technology can transform the way goods are transported and how logistics processes and the dynamics within supply chains can be improved. On the other hand, it aims to understand how companies in the supply chain of the pharmaceutical market in Portugal view these transformations from the point of view of the logistics operations they develop. Therefore, this research aims to evaluate if it is possible to implement this technology in the sector and in which activities its use will bring more benefits and may be feasible. The main results allow us to conclude that autonomous vehicles are already a reality in various activities, particularly for logistics operations carried out in restricted environments such as warehouses. In this segment of warehouse activities, companies in the sector under study are more willing to invest in autonomous vehicles. The results indicate that companies do not believe in the possibility of these vehicles being used in the distribution of medicines in the short and medium-term, and there are still factors that limit the introduction of this technology in this market.A transformação digital torna o ambiente empresarial cada vez mais competitivo. As empresas devem seguir essa transformação, caso queiram diferenciar-se e construir uma posição competitiva sólida nos mercados em que operam. Neste sentido, é crucial reconhecer a importância das novas tecnologias na melhoria das operações logísticas e as vantagens que daí advêm. Entre estas tecnologias destacam-se os veículos autónomos. Deste modo, o presente estudo tenta, por um lado, compreender de que forma é que a tecnologia dos veículos autónomos poderá transformar a maneira como os bens são transportados, e como os processos logísticos e as dinâmicas dentro das cadeias de abastecimento podem ser melhorados. Por outro lado, visa perceber como é que as empresas da cadeia de abastecimento do mercado farmacêutico em Portugal, encaram estas transformações do ponto de vista das operações logísticas que desenvolvem. Assim sendo, esta investigação pretende avaliar se será possível implementar esta tecnologia no sector e em que atividades a sua utilização trará mais benefícios e poderá ser viável. Os principais resultados alcançados permitem concluir que, os veículos autónomos já são uma realidade em várias atividades, nomeadamente nas operações logísticas efetuadas em ambientes restritos como armazéns. É neste segmento das atividades de armazém, que as empresas do sector em estudo estão mais recetivas em apostar na utilização de veículos autónomos. Os resultados indicam que as empresas não acreditam na possibilidade destes veículos serem utilizados na distribuição de medicamentos a curto e medio prazo, existindo ainda fatores que limitam a introdução desta tecnologia neste mercado

    Autonomous ground vehicles in urban last-mile delivery : an exploration of the implementation feasibility and consumer’s acceptance

    Get PDF
    E-Commerce has rapidly changed the urban last-mile delivery in recent years, and Courier-, Express- and Parcel (CEP) companies are challenged by the increasing demand. Service robotics with autonomous vehicles are subject to be the catalyst for transforming the industry. Considering the infancy and lack of research on the subject, the purpose of this study is to explore the concept of autonomous ground vehicles (AGVs) in urban last-mile delivery from two perspectives. First, data about the industry and insights from the technology provider summarize the status quo of recent developments and implementation barriers with the help of expert interviews. The findings show obstacles in the technological maturity and regulatory framework. Moreover, although only road-AGVs (rAGVs) will significantly change the industry, sidewalk-AGVs (sAGVs) act as a proof of concept as the implementation is more feasible. In addition, they create new premium services for the consumers. Second, an attempt to determine the consumer’s acceptance of sAGVs, using the combination of the technology acceptance model and the technology readiness index, is made with an online survey. The proposed research model is analysed by means of simple regression analysis, and all hypotheses are supported. The majority of the respondents have a positive attitude towards the concept of sAGVs for delivery and consider using it when the safety of their delivery goods is guaranteed. This dissertation enriches the literature on human-robot acceptance as well as the management of CEP-companies to increase the engagement in the implementation of sidewalk-AGVs to increase service innovation for consumers.O comércio electrónico mudou rapidamente a entrega urbana de bens ao consumidor, e as empresas de Correio Expresso Urgente são desafiadas pela procura crescente. Os serviços robóticos com veículos autónomos serão provavelmente o catalisador da transformação desta indústria. Considerando a falta e o estágio inicial de investigação, este estudo explora o conceito de veículos autónomos terrestres (AGVs) na entrega urbana de bens ao consumidor considerando duas perspetivas. Uma primeira será a de recolher dados sobre a indústria e insights de fornecedores da tecnologia, sumarizando os mais recentes desenvolvimentos e as barreiras à implementação, com a ajuda de entrevistas a especialistas. Os resultados revelam obstáculos na maturidade tecnológica e enquadramento regulamentar. Adicionalmente, embora apenas os AGVs rodoviários (rAGVs) virão a alterar significativamente a indústria, os AGVs de passeio (sAGVs) atuam como prova de conceito, dada a sua implementação viável. Em segundo lugar, a aceitação de sAGVs por parte do consumidor é determinada através da combinação de modelos de aceitação tecnológica e do índex de prontidão de tecnologia, via questionário online. O modelo de investigação proposto é testado por meio de análise de regressão simples, e todas as hipóteses são suportadas. A maioria dos participantes tem uma atitude positiva em relação aos sAGVs para entrega, e considera usá-los se a segurança dos seus bens for garantida. Esta dissertação enriquece a literatura sobre aceitação humana-robot, bem como a gestão de empresas de Correio Expresso Urgente, aumentando o envolvimento na implementação de sAGVs e fomentando a inovação em serviços para o consumidor

    Ongoing innovations in automated and connected road vehicles create a path of radical transformation of personal mobility, the automotive industry, trucking, public transit, the taxi industry, urban planning, transportation infrastructure, jobs, vehicle ownership, and other physical and social aspects of our built world and daily lives. In considering automated vehicle (AV) deployments and their cost, as well as the changes in traffic volume, congestion, rights of way, and the complexities of mixed fleets with both automated and non-automated vehicles, the time frame of impacts can only be surmised. Still, it is worth considering a framework for understanding and managing the forthcoming process of change covered in this perspective

    Towards Autonomous and Safe Last-mile Deliveries with AI-augmented Self-driving Delivery Robots

    In addition to its crucial impact on customer satisfaction, last-mile delivery (LMD) is notorious for being the most time-consuming and costly stage of the shipping process. Pressing environmental concerns combined with the recent surge of e-commerce sales have sparked renewed interest in automation and electrification of last-mile logistics. To address the hurdles faced by existing robotic couriers, this paper introduces a customer-centric and safety-conscious LMD system for small urban communities based on AI-assisted autonomous delivery robots. The presented framework enables end-to-end automation and optimization of the logistic process while catering for real-world imposed operational uncertainties, clients' preferred time schedules, and safety of pedestrians. To this end, the integrated optimization component is modeled as a robust variant of the Cumulative Capacitated Vehicle Routing Problem with Time Windows, where routes are constructed under uncertain travel times with an objective to minimize the total latency of deliveries (i.e., the overall waiting time of customers, which can negatively affect their satisfaction). We demonstrate the proposed LMD system's utility through real-world trials in a university campus with a single robotic courier. Implementation aspects as well as the findings and practical insights gained from the deployment are discussed in detail. Lastly, we round up the contributions with numerical simulations to investigate the scalability of the developed mathematical formulation with respect to the number of robotic vehicles and customers
