ULTRAS: Iterative Development of a Comprehensive Toolchain for Urban Air Mobility Simulation

A modular urban air mobility (UAM) simulation toolchain was iteratively developed in the project ULTRAS (Urban Air Transportation Simulation). Twelve modules combined passenger demand, vertiports, routing, trajectories, sectorized capacities, costs, scheduling, and infrastructure scaling, communication, and control (GNC). Three iterations evolved modules from minimum viable products (MVP) to mature frameworks, adding and adapting assumptions, functionality, and interfaces. In each iteration, modules were integrated to a workflow, enabling comprehensive simulation and evaluation.
