Road Traffic Violations Detection
Budget: $30 – $250 USD
Build a web platform that:
Receives real-time GPS positions of vehicles (via API / Webhooks from GPSWOX or another GPS tracking software).
Cross-checks these positions with a multi-country fixed speed camera (radar) database.
Detects traffic violations (e.g., speeding) and displays them in a dashboard with a map.
Suggested Tech Stack
Backend: Laravel (PHP 8.3)
Database: PostgreSQL + PostGIS (geospatial support)
Queue & Cache: Redis
Frontend: React/Next.js or Laravel Blade + Tailwind
Mapping: Leaflet or MapLibre (OpenStreetMap)
File storage: MinIO or S3 (evidence files, exports)
Workflow
The GPS software sends positions {device_id, lat, lon, speed, timestamp} to a webhook endpoint.
Backend stores points in the database (positions table).
A background job checks if the position is near a radar (PostGIS ST_DWithin).
If speed > radar speed limit and no recent infraction exists for this (vehicle, radar) pair → create a new violation record.
Violations are viewable in a dashboard + map with CSV/PDF export.
Core Database Tables
vehicles — vehicle info (plate, owner)
devices — GPS trackers / telematics units
radars — location, speed limit, type
positions — GPS points received
violations — speed detected, radar reference, timestamp
Admin / Frontend Features
Interactive map showing radars & violations
Filters (vehicle / date / country)
CSV / PDF export
Radar management (import CSV/GeoJSON)
User & role management (admin, read-only, etc.)
Technical Key Points
Use GIST indexes on geometry columns for fast spatial queries.
Partition the positions table (daily or weekly) to handle large data.
Configurable tolerance (e.g., +3 km/h above speed limit).
Cool-down logic to avoid duplicate violations if a car stays near one radar.
Security & Compliance
HTTPS + data encryption at rest
Access control (admin vs. read-only users)
Data retention policy: positions (90 days), violations (3–5 years)
GDPR/local data privacy compliance if personal vehicle tracking
