With the growth of the world population and the acceleration of urbanization, the need for sustainable solutions for urban mobility becomes increasingly pressing. In this context, smart cities promote economic and social development through innovative solutions to various problems faced by society, such as access to essential services, mobility, excessive energy consumption, security failures, and the implementation of efficient and high-speed urban air transportation. In the realm of urban mobility, the main bet lies in the use of aerial vehicles. Unlike traditional transportation systems, such as cars or trains, which are limited by terrestrial road space, flying vehicles, such as drones and air taxis, do not compete for space in terrestrial traffic. They have a greater degree of spatial and temporal freedom, shorter routes, and consequently, less stress to their users. Large companies and researchers worldwide are developing different architectures, algorithms, and techniques to enable air taxi transportation, aiming to serve a portion of the population with safety and autonomy. However, one of the main issues that hinder the dissemination of air taxis is operational safety and protection against threats (safety and security), as a simple failure can result in the loss of high-value assets, the vehicle itself, and above all, cause injuries to human lives, including fatalities. Despite efforts, the literature on safety in this context is still specific and limited. Therefore, the main objective of this thesis is to present the results and the definition of the ReSilienT aiR taxis architectUre for Smart cities (STRAUSS), an innovative safety solution for air taxis, designed to be resilient, robust, and fault-tolerant. STRAUSS aims to ensure continuous and safe operation, even under adverse conditions, whether they are due to intentional or accidental events. The innovation of STRAUSS lies in integrating mechanisms that diagnose failures and attacks, allowing real-time decision-making to mitigate risks and restore the aircraft, and adopting the best possible strategy in unexpected situations. The STRAUSS architecture comprises four main components: three platforms and an interface, each with distinct objectives and functionalities. These components are named Jetson Diagnosis Platform, Jetson Decision Platform, Resilience Platform, and Jetson Interface. Each platform was carefully designed to work in a dense urban environment, ensuring high safety, security, and operational efficiency for air taxis in smart cities, for passengers, and for the environment. Different studies have been conducted to validate the effectiveness of the STRAUSS architecture, achieving significant results on all platforms, for example, a 21% higher accuracy in diagnosing faults and attacks compared to recent studies in the literature.
