Step 01
Vehicle Enters Zone
A vehicle enters the free-flow tolling zone without stopping at a physical barrier.
● System Architecture
Barrierless tolling powered by FASTag, ANPR and multi-frame AI intelligence.
FASTAG MLFF identifies a moving vehicle, reads its registration plate, verifies the associated record, processes the toll decision, and updates operational analytics — without requiring a conventional toll barrier.
End-to-End MLFF Processing Flow
From vehicle entry to transaction or violation decision.
Step 02
FASTag Identification
The system receives the FASTag identifier supplied to the scan workflow for vehicle verification.
Step 03
ANPR Capture
Image or video input is processed to locate the vehicle registration plate.
Step 04
AI Recognition
YOLO detects the plate; OCR reads it; video tracking and multi-frame consensus improve reliability.
Step 05
Verify & Process
The recognized plate is matched with registered data to process a toll transaction or violation.

Inside the AI Pipeline
How raw visual input becomes a verified tolling event.
01
Plate Detection
The ANPR pipeline analyzes uploaded images or video frames. A trained YOLO model identifies the license-plate region and extracts the plate crop for recognition.
02
OCR & Plate Normalization
PaddleOCR and EasyOCR analyze enhanced plate crops. Recognition candidates are cleaned and validated before being accepted as plate evidence.
03
Multi-Frame Video Intelligence
ByteTrack maintains identity across frames. Multiple OCR observations are accumulated and fuzzy-clustered so the final plate is selected from consistent evidence instead of one frame.
04
Database Verification & Toll Decision
The recognized registration is checked against registered vehicle and FASTag records. The system records a successful toll transaction or flags a violation for review.
Decision Outcome
Every recognized vehicle event reaches one of these operational outcomes.
✅
Verified Transaction
Registered vehicle and FASTag data match. Toll processing is recorded and dashboard analytics are updated.
OR
🚨
Violation Event
An unmatched or unregistered plate event is recorded for operational review and shown in the violations dashboard.
