Tested on NGSIM and highD datasets, DSiGAT achieves intention prediction accuracies above 90% and reduces trajectory error by up to 52.94% compared to baselines. The framework improves scene-level coherence and safety for autonomous driving systems.", "body_md": "arXiv:2607.09740v1 Announce Type: new\nAbstract: Safe motion planning in advanced driver-assistance systems and autonomous vehicles requires an accurate understanding of how the surrounding traffic scene is likely to evolve. However, many existing lane-change prediction methods remain centered on a single target vehicle, while multi-agent forecasting approaches often describe scene evolution only through future positions and provide limited explicit information about the maneuver associated with each vehicle. This study proposes a dynamic scene graph attention framework that predicts the lane-change intention and future trajectory of every relevant vehicle within a local traffic scene. The scene is represented as a time-varying interaction graph in which vehicles are modeled as nodes and their spatial and kinematic relationships are encoded through explicit edge features. Temporal graph-attention message passing captures evolving inter-vehicle dependencies and pre-maneuver cues, while an intention-guided decoder links each predicted maneuver to its corresponding future motion. A scene-level consistency objective further encourages compatible multi-vehicle futures. Experiments on the NGSIM I-80, NGSIM US-101, and highD datasets demonstrate consistent improvements over competing baselines. DSiGAT achieves intention prediction accuracies of 90.12% and 90.97% on NGSIM I-80 and US-101, respectively, and reduces trajectory RMSE by up to 52.94% relative to the strongest baseline. It also produces lower inter-agent collision rates and joint displacement errors, indicating more coherent scene-level predictions. Ablation, sensitivity, robustness, and qualitative analyses further validate the contribution of the proposed components and the effectiveness of the scene-focused formulation.", "url": "https://wpnews.pro/news/a-dynamic-scene-interaction-reasoning-framework-for-scene-level-lane-change-and", "canonical_source": "https://arxiv.org/abs/2607.09740", "published_at": "2026-07-14 04:00:00+00:00", "updated_at": "2026-07-14 04:24:11.799885+00:00", "lang": "en", "topics": ["autonomous-vehicles", "machine-learning", "neural-networks", "computer-vision"], "entities": ["DSiGAT", "NGSIM I-80", "NGSIM US-101", "highD"], "alternates": {"html": "https://wpnews.pro/news/a-dynamic-scene-interaction-reasoning-framework-for-scene-level-lane-change-and", "markdown": "https://wpnews.pro/news/a-dynamic-scene-interaction-reasoning-framework-for-scene-level-lane-change-and.md", "text": "https://wpnews.pro/news/a-dynamic-scene-interaction-reasoning-framework-for-scene-level-lane-change-and.txt", "jsonld": "https://wpnews.pro/news/a-dynamic-scene-interaction-reasoning-framework-for-scene-level-lane-change-and.jsonld"}}
