SafeNav is a full-stack AI-powered travel safety platform designed to help users make safer travel decisions based on real-time environmental conditions and their personal health profile.
Unlike traditional navigation apps that primarily optimize for speed, SafeNav evaluates routes using live air quality, weather, traffic, and road conditions to calculate a deterministic safety score. Users with different health profiles, such as cardiac or respiratory conditions, receive personalized recommendations and route analysis.
The platform integrates multiple real-time services, including TomTom Routing, OpenWeatherMap, WAQI, Firebase, and Google Gemini AI, to provide intelligent travel assistance, personalized safety advice, and route analytics.
SafeNav also includes a secure travel document vault where users can store passports, visas, insurance documents, and other important files using encrypted storage with integrity verification. AI-powered OCR helps extract and summarize document information.
Additional features include an admin dashboard for monitoring API usage and users, real-time analytics, audit logging, offline Progressive Web App support, and AI-powered travel tools such as itinerary generation, translation, and document analysis.
Built with Python, Flask, JavaScript, Firebase, and Google Gemini, SafeNav demonstrates production-style backend engineering, secure system design, AI integration, and real-world API orchestration.
Future Enhancements
• Multiple alternative health-optimized routes
• Wearable device integration (heart rate and SpO₂)
• Predictive AQI and weather forecasting
• Elevation-aware route analysis
• Real toll pricing integration
• Push notifications for document expiry
• Native Android and iOS applications
• Redis caching for faster responses
• Background task processing with Celery
• PostgreSQL-based document metadata storage
• Post-quantum cryptography support
• Emergency SOS and location sharing
Known Issues
• AI responses may be unavailable if the Gemini API reaches rate limits; the system falls back to rule-based responses.
• AQI data depends on WAQI coverage and may not be available in every location.
• The Quantum encryption option is currently a placeholder for future post-quantum algorithms.
• Toll cost estimation uses an approximate formula rather than real toll pricing.
• Some advanced features require an active internet connection.
