OverFlowLight: Real-Time Gridlock Prevention and Traffic Signal Optimization for Urban Intersections

Batch of CS/ML arXiv submissions (29 Jun 2026) covering applied ML, algorithms, and scientific computing. Highlights: OverFlowLight — a deployed, real-time traffic-signal framework using camera/radar sensing and hybrid rule/RL control that inserts overflow phases; deployments across 43 intersections report a 60.4% reduction in overflow incidents and +18.2% network throughput. RANSAC Scoring Done Right — closed-form marginalization of inlier scale under an Inverse-Gamma prior yields a scale-free RANSAC score computable in O(N log N) and improves robustness to threshold miscalibration.
