flag Johns Hopkins AI tool predicts crashes using traffic, weather, and behavior data to help reduce accidents.

flag Johns Hopkins engineers have developed an AI tool called SafeTraffic Copilot that predicts car crashes by analyzing traffic patterns, weather, road design, and driver behavior. flag Using generative AI and data from over 66,000 accidents, the system helps policymakers evaluate how changes like adjusting traffic signal timing could reduce crash rates. flag It aims to improve road safety in diverse environments, including areas with high motorcycle use, and is designed to support data-driven decisions in urban planning. flag The research was published in Nature Communications in October 2025.
