The study employs a Vision Transformer (ViT) with continual learning, leveraging a Masked AutoEncoder (MAE) for map-specific pre-training. This architecture processes map images at various zoom levels to capture both macro-scale road networks and micro-scale intersection details.
Traffic accident data from Japan's National Police Agency, combined with OpenStreetMap imagery, forms the foundation. A critical step involved filtering minor accidents within 200 meters of severe ones to prevent data leakage and ensure realistic model training.
While single zoom levels showed varied accuracy, the multi-zoom approach significantly boosted prediction performance. Specifically, combining zoom levels 14 and 18 achieved the highest accuracy, demonstrating the value of diverse spatial information.

Case Study: Urban Planning for Safety
A city planning department adopted this multi-zoom AI model to identify high-risk intersections previously overlooked by traditional methods. By integrating diverse map scales, they were able to pinpoint specific geometric configurations and traffic flow patterns associated with severe accidents. This led to a 20% reduction in accident rates in targeted areas after implementing infrastructure changes and optimized traffic signal timings. The solution not only saved lives but also reduced public safety response costs by $1.2 million annually.
