TranSimHub:A Unified Air-Ground Simulation Platform for Multi-Modal Perception and Decision-Making
This addresses the problem of limited progress in cross-domain perception and decision-making for researchers in urban intelligent transportation management, though it is incremental as it builds on existing simulation concepts.
The authors tackled the lack of a unified multi-modal simulation environment for air-ground collaborative intelligence by developing TranSimHub, a platform that provides synchronized multi-view rendering across RGB, depth, and semantic segmentation modalities and supports information exchange and scenario creation, released as open-source.
Air-ground collaborative intelligence is becoming a key approach for next-generation urban intelligent transportation management, where aerial and ground systems work together on perception, communication, and decision-making. However, the lack of a unified multi-modal simulation environment has limited progress in studying cross-domain perception, coordination under communication constraints, and joint decision optimization. To address this gap, we present TranSimHub, a unified simulation platform for air-ground collaborative intelligence. TranSimHub offers synchronized multi-view rendering across RGB, depth, and semantic segmentation modalities, ensuring consistent perception between aerial and ground viewpoints. It also supports information exchange between the two domains and includes a causal scene editor that enables controllable scenario creation and counterfactual analysis under diverse conditions such as different weather, emergency events, and dynamic obstacles. We release TranSimHub as an open-source platform that supports end-to-end research on perception, fusion, and control across realistic air and ground traffic scenes.
