Physics-Informed AI-Enhanced Multimodal Modeling and Governance: Improving Safety and Resilience for Data-Limited Transit Corridors

Limited sensor coverage and fragmented, mode-specific modeling infrastructure hinder the holistic monitoring of modern transportation networks. The resulting data blind spots prevent current models from capturing dynamic, cross-modal dependencies, where a disruption in one mode, such as a metro closure, triggers cascading surges in others, forcing planners and Traffic Management Centers to rely on reactive, siloed strategies. To improve the state of the art, this project proposes a Virtual Sensor paradigm driven by physics-informed generative artificial intelligence (AI). By integrating fundamental transportation physics with generative deep learning, the framework synthesizes high-fidelity data for sensor-sparse regions by inferring correlations from existing sensing infrastructure, creating cost-effective virtual data streams that simulate physical sensors and provide more complete multimodal network data for real-time operations and long-term planning. The project also evaluates the policy and governance dimensions of integrating emerging AI use cases, such as AI-generated data, into the Delaware Department of Transportation (DelDOT)’s planning, design, and operations.
