How our system deters school bus traffic violations

A step-by-step technical flow of detection, capture, validation, and delivery.

Camera captures vehicle

1. Camera Detection & Capture

High-speed camera sensors mounted on the exterior of the bus monitor the surrounding traffic during all bus stops with passengers exiting. When an object enters the detection zone, the system triggers a short, high-resolution burst capture to ensure at clear imaging. Exposure, shutter timing, and IR illumination are adjusted dynamically for day/night conditions.

Hardware: Global-shutter camera, IR illuminator, low-latency capture buffer.

Image processing and cropping

2. Preprocessing & Plate Localization

Captured frames are run through a preprocessing pipeline. A lightweight object detection model isolates vehicle and plate regions. Multiple candidate crops are kept and scored by quality metrics.

Software: Lightweight CNN detector, GPU/edge-accelerated preprocessing.

Optical character recognition

3. OCR & Confidence Scoring

Crops are sent to an OCR engine optimized for variable fonts and partial occlusion. Multiple hypotheses are generated and ranked by confidence. Post-processing applies multiple AI-enhanced methods to increase accuracy and eliminate false positives.

Validation, timestamping, and delivery

4. Validation, Timestamping & Delivery

Verified plates are timestamped, geo-tagged, and packaged with evidence frames. Secure delivery of violation packages to enforcement endpoints occurs over TLS; optionally batched to meet local retention and privacy policies. Audit logs and chain-of-custody metadata are included for legal acceptability.

Police Mobile App

5. Ticket Determination Mobile Application

Verified law enforcement personnel, including off-duty officers, securely receive and review incident packages to determine appropriate ticketing outcomes. The SecuriStop Mobile Application, PatrolSight, developed in-house, facilitates this process by streamlining verification, evidence review, and decision-making for authorized police officers.

Payment Processing Service

6. Payment Processing

SecuriStop can optionally provide comprehensive payment processing capabilities, streamlining operations and reducing the administrative burden on government websites and personnel. Our goal is to deliver a seamless, end-to-end image-to-payment solution that enables efficient citation management without placing additional strain on government resources.
