Smart Traffic Management
Adaptive Traffic Grid — AI-Powered Signal & Flow Intelligence
LyDian AI's Adaptive Traffic Grid gives cities and transportation agencies a real-time AI layer over their existing infrastructure. From intersections to corridor-level orchestration, ATG continuously senses, predicts, and acts to keep traffic moving, emergency vehicles unobstructed, and multimodal networks balanced.
Six Core Traffic Intelligence Modules
Each module operates independently or as part of a unified city-wide grid, connecting to your existing signal controllers, sensors, and data feeds.
Per-intersection signal plans update in sub-second cycles based on live queue lengths, pedestrian demand, and downstream saturation. Replaces fixed time-of-day schedules with continuous optimization.
Fuses loop detector counts, camera feeds, probe vehicle data, and weather inputs into a rolling 15-minute traffic state forecast. Enables proactive signal adjustments before bottlenecks form.
Upon dispatch notification, ATG computes the fastest clear corridor, preempts conflicting phases along the route, and holds greens ahead of the vehicle in real time — reducing response-path delay without disrupting the broader network.
Co-optimizes signal plans for transit vehicles, cyclists, and pedestrians alongside private cars. Transit Signal Priority extends green time for behind-schedule buses without starving cross-traffic.
Computer-vision and statistical anomaly detection identify stalls, wrong-way events, and spillback within seconds of onset. Triggers automatic re-routing signals and operator alerts with geo-tagged evidence clips.
Exposes a standards-compliant V2X API (ETSI ITS-G5 / DSRC / C-V2X) so equipped vehicles receive signal phase and timing data, speed advisories, and hazard alerts — and contribute probe data back to the optimization engine.
Sense → Predict → Optimize → Act
A four-stage closed-loop architecture that processes multi-source sensor data and pushes signal commands back to field hardware in under 500 ms.
Loop detectors, radar, video analytics, V2X probes, GTFS-RT feeds, and weather stations stream into a unified city data bus. All inputs are timestamped and fused at edge nodes before transmission.
A spatio-temporal model maintains a 15-minute rolling forecast of volume, occupancy, and queue length at every monitored intersection. Incident probability scores update continuously as anomalies surface.
A network-level optimizer solves for minimum total delay across the corridor or district, respecting phase constraints, pedestrian minimums, and active priority requests from emergency or transit vehicles.
Computed signal plans are pushed via NTCIP or direct controller API to traffic signal cabinets. Every command is logged with an audit timestamp for regulatory reporting and post-event analysis.
Scenarios Where ATG Delivers
Designed for transportation engineers, city operations centers, and regional mobility agencies managing corridors from a few intersections to city-scale networks.
High-volume commuter corridors with 15–40 signalized intersections benefit most from coordinated green-wave progression. ATG dynamically shifts offset and split plans as demand peaks shift across the AM and PM periods, preventing the upstream spillback that fixed coordination plans cannot handle.
When fire, EMS, or law enforcement units are dispatched, ATG computes a clear-path green wave within seconds, preempts conflicting phases, and restores normal operation within one cycle after the vehicle passes. Compatible with AVL-based CAD system integrations.
Stadium, arena, and convention center events generate predictable surge patterns. ATG pre-loads event-specific signal plans, monitors real-time queue growth, and activates staggered egress sequencing to clear venues faster while protecting surrounding neighborhoods from overflow cut-through traffic.
Municipalities running AV pilot programs can deploy ATG as the V2X infrastructure backbone. Vehicles receive SPaT (Signal Phase and Timing) broadcasts and contribute anonymous probe data, enabling the city to quantify AV behavior within the broader mixed-fleet traffic stream.
