OD-RASE Framework Overview

Comparison of various methods for infrastructure improvement design. (a) is based on expert knowledge, while (b) represents our proposed approach. Our method not only outputs infrastructure improvement plans for road structures that cause traffic accidents but also generates visual representations of roads after improvement.

Abstract

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.

Ontology-Driven OD-RASE Dataset

We introduce the OD-RASE dataset, constructed through ontology-driven data filtering to enhance the reliability of infrastructure improvement proposals. The dataset contains pre-accident road images with automatically annotated improvement proposals generated by large-scale visual language models.
