Vehicle Model Simplification for Efficient Pedestrian Safety Assessment Pablo Lozano･Simona Roka･Lucia Vizuete (Applus IDIADA)･Xufeng Li (IDIADA China)･Andre Eggers (BASt) Pedestrian accidents represent a persistent global public health challenge requiring continued attention. Current assessments employ advanced impactor systems; however, these standardized methods face inferior bio-fidelity in capturing biomechanical responses compared to HBM). HBMs offer superior anatomical accuracy but require substantial computational resources, limiting their practical application in safety evaluations. This research investigates a vehicle model simplification methodology to enhance computational efficiency while maintaining HBM accuracy. The study employs the open-source Nissan Rogue model with HBMs, alongside conventional impactor models, within the LS-DYNA simulation environment. The proposed simplification approach reduces computational burden while preserving kinematic fidelity, thereby enabling more extensive investigations. |

AI-driven motorcycle risk analysis: Novel insights for safety development Genis Mensa･Diego Martin･Pol Garriga (Applus IDIADA) Building upon our published Exposure-Based Risk Index methodology, we present novel AI-driven analysis of 4+ million Spanish motorcycles revealing counterintuitive safety patterns. Key findings: newer motorcycles (0-5 years) show +15.4% accident overrepresentation despite comprising minority of fleet; middle-mileage vehicles (2,000-5,000 km/year) demonstrate peak risk in non-linear relationship; low engine motorcycles (≤125cc) can be more dangerous for serious injuries than high engine variants. IDIADA's integration of advanced data analytics with comprehensive physical and virtual crash testing capabilities enables motorcycle OEM partners to develop targeted, evidence-based safety strategies based on quantified real-world risk patterns. |

前面衝突における顎顔面骨折に対する拘束装置の効果の分析 井田 等・浅岡 道久・青木 雅司（豊田合成）・一杉 正仁（滋賀医科大学） 顎顔面骨折は治療期間が長く，手術後の疼痛，顎間固定による開口制限などにより，負傷者に多大なストレスを与える．本研究は，自動車事故における顎顔面骨折の発生率とその影響因子を事故調査データベースにより分析し，どのような乗員保護技術が有効かを明確にすることを目的とした． |
