OD-RASE: Ontology-Driven Risk Assessment and Safety Enhancement for Autonomous Driving
- 基于交通领域知识构建知识图谱,指导风险识别
- 通过大模型生成改进建议,准确预测事故道路结构
- 适合自动驾驶安全研究与智能交通系统开发者
尽管自动驾驶系统在感知性能上表现良好,但在应对罕见场景或复杂道路结构时仍存在局限。这类道路设施原本为人类驾驶设计,安全改进通常在事故发生后才引入,这种被动模式对自动驾驶系统构成挑战,因其需要主动防范风险。为此,本文提出OD-RASE框架,通过检测引发交通事故的道路结构,并将其关联至基础设施优化。首先,基于交通系统专业领域知识构建本体(ontology);同时,利用大规模视觉语言模型(LVLM)生成基础设施改进建议,并通过本体驱动的数据过滤提升其可靠性。该过程自动标注事故前道路图像中的改进建议,构建新数据集。此外,提出基线方法(OD-RASE模型),结合LVLM与扩散模型,生成改进后的道路环境图像及相应优化方案。实验表明,本体驱动的数据过滤可实现对事故道路结构及其改进计划的高精度预测。本工作有助于提升整体交通环境安全性,推动自动驾驶系统更广泛的应用。
原文摘要 · Abstract (English)
Although autonomous driving systems demonstrate high perception performance, they still face limitations when handling rare situations or complex road structures. Such road infrastructures are designed for human drivers, safety improvements are typically introduced only after accidents occur. This reactive approach poses a significant challenge for autonomous systems, which require proactive risk mitigation. To address this issue, we propose OD-RASE, a framework for enhancing the safety of autonomous driving systems by detecting road structures that cause traffic accidents and connecting these findings to infrastructure development. First, we formalize an ontology based on specialized domain knowledge of road traffic systems. In parallel, we generate infrastructure improvement proposals using a large-scale visual language model (LVLM) and use ontology-driven data filtering to enhance their reliability. This process automatically annotates improvement proposals on pre-accident road images, leading to the construction of a new dataset. Furthermore, we introduce the Baseline approach (OD-RASE model), which leverages LVLM and a diffusion model to produce both infrastructure improvement proposals and generated images of the improved road environment. Our experiments demonstrate that ontology-driven data filtering enables highly accurate prediction of accident-causing road structures and the corresponding improvement plans. We believe that this work contributes to the overall safety of traffic environments and marks an important step toward the broader adoption of autonomous driving systems.
