Automate tolling or fines for traffic rule violations with instant plate capture and photo evidence.
Monitor traffic flow by vehicle types — cars, trucks, buses, up to 9 classes — for priority-based real-time signal management.
Generate real-time reports and statistical data for authorities on traffic patterns and law enforcement outcomes.
Command traffic lights and barriers directly based on plate whitelist or blacklist matches.

Engine 02 · Vehicle Classification

Car Recognition & Vehicle Classification

Classify vehicles into 9 types — cars, trucks,light trucks, motorcycles, buses, trams, SUVs, vans, and utility vehicles — and identify the manufacturer from over 60 producers, in real time.

Prioritize traffic at intersections based on vehicle type — buses and trams receive green light priority automatically.
Manage congestion by directing heavy vehicles to alternate routes during peak hours.
Collect detailed data on vehicle mix at each intersection, giving urban planners actionable evidence for infrastructure decisions.
Combine with LPR to link every plate reading to a specific vehicle type, colour and maker.

Engine 03 · Line Counter

Line Counter — Virtual Line Cross Detection

Draw a virtual line across any lane or path. Metrici counts every vehicle or pedestrian that crosses it — per direction, per class, per minute — in real time with no road sensors needed.

Measure traffic density in real time by counting how many vehicles cross a virtual line over any time frame.
Trigger signal changes based on traffic load — extend green light duration automatically during high-flow periods.
Integrate with pedestrian crossings, counting the number of people waiting at the light to prioritize their crossing time.
Deploy multiple independent lines per camera — each lane, each direction, each object type tracked separately.
Photo witness saved for every crossing event — timestamped, classified and stored for audit or analysis.

Metrici Area Counter monitoring zone occupancy at station

Live · Area Counter

Zone occupancy and crowd density monitoring Real-time count of people in a defined area — alerts fire when thresholds are crossed

Engine 04 · Area Counter

Area Counter — Zone Occupancy Detection

Count the number of vehicles or pedestrians present within a designated zone — a waiting lane, a crosswalk, an intersection approach — and react dynamically to what the AI sees.

Monitor traffic queues at intersections to dynamically adjust signal timings based on actual waiting count.
Detect traffic jams early and trigger rerouting algorithms or adjust traffic light phases to reduce downstream congestion.
Count pedestrians waiting in crosswalk areas to ensure safe crossing times — automatically extended when needed.
Alert operators when zone occupancy exceeds a defined threshold — per zone, per camera, per time of day.

Engine 05 · People Recognition

Pedestrian Detection & Safety

AI-based computer vision detects people at crossings, in jaywalking zones, and in any pedestrian area — enabling real-time safety decisions without any physical infrastructure.

🚸

Crosswalk Safety

Detect people in crosswalks and jaywalking near intersections. Emit instant alerts to signal operators or connected systems when a crossing is actively in use.

⏱️

Adaptive Crossing Times

Automatically adjust pedestrian crossing times depending on the volume of people waiting. More people waiting means a longer green phase — decided by the AI, not a fixed timer.

📊

Urban Safety Planning

Ensure compliance with pedestrian traffic rules and improve urban traffic safety planning by gathering continuous data on pedestrian movement patterns across intersections.

Engine 06 · Enforcement

Red Light Runner Detection

Metrici monitors traffic lights continuously — using cameras and optional sensors — to detect every vehicle that fails to stop at a red light, capture evidence, and trigger enforcement automatically.

🚦

Catch Every Violation. Automatically.

Metrici monitors each traffic light phase and flags any vehicle that crosses the stop line during a red phase — combining LPR plate capture, vehicle classification, and timestamped photo evidence in a single automated workflow.

Use AI to monitor traffic lights and detect vehicles not stopping correctly at red.
Integrate with car recognition and LPR to record every vehicle that violates red light rules.
Automatically capture license plates and send real-time violation data to authorities.
Issue instant fines or tickets via automated systems — no officer required on site.
Track red-light violations for traffic law enforcement and safety analytics over time.

See red light runner page →

📷

Photo Evidence

Every violation captured with a timestamped photo of the vehicle at the moment of crossing — admissible evidence for enforcement.

🔢

LPR Integration

Plate read at the same instant as the violation — vehicle is identified, logged and queued for fine issuance without human intervention.

📱

Instant Notification

Integration with smart city systems can send notifications directly to violators via mobile applications or email within seconds.

📈

Violation Analytics

Aggregate data on violation frequency by intersection, time of day, and vehicle class — informing signal timing and enforcement deployment.

System Architecture

How It All Connects

Data flows from cameras at the intersection through AI processing layers to real-time traffic management, enforcement, and analytics — in a continuous, closed feedback loop.

Layer 01

📷

Data Collection

Cameras capture video of traffic lights, vehicle movement, and pedestrian crossings. LPR cameras read plates continuously.

Layer 02

🧠

AI Processing

AI algorithms process every video feed simultaneously — vehicle recognition, red-light detection, pedestrian tracking, plate reading — in real time on the Metrici server.

Layer 03

🚦

Real-Time Control

Line and Area Counter adjust signals dynamically. AI prioritizes emergency vehicles, buses, and trams. Pedestrian crossing times extend automatically based on live counts.

Layer 04

⚖️

Enforcement & Reporting

Red-light violations trigger automated citations. Violation data, traffic statistics and classified counts feed dashboards, city systems and law enforcement in real time.

🔁 Feedback Loop

Real-time feedback between AI systems and traffic lights ensures signals change according to actual road conditions, traffic density and pedestrian activity — not fixed schedules.
Machine learning models improve over time using historical data, optimizing traffic flow predictions for specific intersections and time-of-day patterns.
Anomalies — sudden surges, accidents, blocked lanes — are detected and escalated within seconds.

🔗 External Integration

Sends event data via HTTP POST to any external system — city traffic management platforms, smart city dashboards, police databases or custom software.
Drives Metrici LED displays at intersections and upstream points with live congestion and routing guidance for drivers.
Integrates with Observer Radar for precise speed measurement alongside LPR and classification data.

Advanced Use Cases

Beyond the Intersection

The same Metrici engine stack applies across corridors, highways, city networks and smart city deployments — at any scale.

🗺️

Smart Routing

Traffic management systems suggest alternate routes based on real-time intersection data — reducing congestion at chokepoints before it forms and distributing load across the network.

📊

Data Analytics & Reporting

Collected data on traffic volume, violations, and vehicle classification is used by city planners to improve infrastructure, reduce bottlenecks and measure the impact of interventions over time.

🚸

Enhanced Pedestrian Safety

Systems extend green light times for pedestrians, trigger flashing signals when jaywalking is detected, and provide city-wide data on pedestrian movement for safer urban design.

🚑

Emergency Vehicle Priority

Detect emergency vehicles approaching an intersection and automatically clear a green corridor — reducing response times and improving road safety without manual operator intervention.

🏙️

City-Wide Network

Connect cameras across an entire city into one unified traffic intelligence platform. Heat maps and flow maps reveal patterns across the network to guide long-term urban planning decisions.

🚛

Heavy Vehicle Management

Identify trucks and semi-trucks in real time and redirect them away from restricted zones, low-clearance bridges or congested corridors — automatically, based on AI classification.
