Abstract
En 中文
• Six key challenges in Mobility Digital Twin development are identified from the literature, including interoperability, adaptability, and automatability. • A model-driven approach is introduced to structure MoDT development through layered abstractions and automated transformations via the developed M2DT tool. • The approach is applied to a real case study for the city of Bologna, using real-world traffic data and open urban infrastructure datasets. • The resulting BoMoDT platform integrates FIWARE and SUMO, supporting simulation, monitoring, and visualization of urban mobility conditions. • Simulation fidelity and monitoring responsiveness are quantitatively evaluated, confirming BoMoDT’s accuracy and effectiveness.
