Researchers have developed PRISA, a framework designed to enhance safety at urban intersections using LiDAR technology. This system employs privacy-preserving sensors to monitor traffic and detect potential conflicts in real-time. PRISA includes a perception layer and a risk assessment module that automatically trains trajectory prediction models without manual annotation, utilizing metrics like Time-to-Collision (TTC) and Predicted Post-Encroachment Time (PPET) to forecast future movements and evaluate risks.
