Edge AI Architecture
TrafficEZ's architecture is built on a decentralized, edge-based processing model. All video analytics for vehicle detection, classification, and density estimation are performed locally within the signal cabinet using embedded processors. This eliminates reliance on cloud connectivity and high-bandwidth backhaul, ensuring autonomous and robust operation, critical for resource-constrained environments.
Adaptive Control Logic
The core of TrafficEZ is its Traffic Density Approximation (TDA) model. It computes green time allocations based on observed red-phase queue density and green-phase discharge efficiency. This macroscopic, cycle-level control adjusts green splits dynamically, responding to real-time demand without altering fixed cycle lengths, intergreen intervals, or pedestrian safety timings, ensuring compliance with existing regulations.
Performance Metrics & Impact
Field evaluations demonstrated significant improvements: 18-32% reduction in per-vehicle red-phase idle time and an estimated 50-200 additional vehicles per hour served on busy approaches. These gains, achieved by converting idle time into productive discharge, translate to reduced congestion, lower fuel consumption, and fewer emissions, directly supporting urban sustainability goals.
Real-World Deployment
Deployed at three intersections in El Salvador City, Philippines, TrafficEZ proved its efficacy under mixed-traffic conditions and operational constraints common in developing cities. The system's stability, absence of oscillatory switching, and local logging capabilities make it a practical, auditable solution for local government units (LGUs) to modernize traffic management incrementally.
18-32%
Average Per-Vehicle Delay Reduction
TrafficEZ consistently reduced per-vehicle red-phase idle time across all study sites, demonstrating significant user-experienced delay reduction without modifying cycle length or pedestrian timings. This translates directly to improved traffic flow and reduced congestion.

Case Study: Robustness in Real-World Philippine Conditions
The field deployment in El Salvador City demonstrated that TrafficEZ's density-driven edge AI approach maintained operational stability under mixed-traffic conditions, variable lighting, and occasional backhaul interruptions. Its design, which uses conservative density thresholds and temporal smoothing, prevented oscillatory phase switching and ensured consistent convergence of green splits, making it a reliable solution for challenging urban environments. Local logging supports auditability and governance reporting, crucial for LGUs.
