🛡️ SafeRoute AI

AI-Powered Accident Prevention System

EPICS 2025 > Engineering safer futures by prioritizing survival over speed.

📖 Overview

Conventional navigation apps (Google Maps, Waze) optimize for time and distance. They often route drivers through hazardous blackspots, narrow lanes, or unlit roads just to save a few seconds.

SafeRoute AI represents a paradigm shift in routing logic. By fusing satellite imagery, geometric vector analysis (road curvature), and real-time environmental data, we calculate a Probabilistic Safety Score (0-100) for every route. We don't just tell you the fastest way; we tell you the safest way.

🚀 Key Features

🧠 1. Geometric Risk Analysis

• Uses OSMnx & NetworkX to download real-world road networks.
• Calculates Road Curvature using vector math to identify sharp, dangerous turns.
• Detects infrastructure risks like Narrow Roads, Poor Lighting, and High-Speed Zones.

🤖 2. SafeBot (AI Assistant)

• Integrated Google Gemini 2.5 Flash-Lite LLM.
• Provides real-time advice on road safety, first aid protocols, and route details.
• Smart Fallback System: Automatically switches to an internal rule-based mode if the internet connection is unstable.

🌍 3. Live Environmental Data

• Real-time AQI (Air Quality Index): Fetched via Open-Meteo API to warn drivers of low visibility due to smog/pollution.
• Weather Integration: Live temperature and condition monitoring.

🆘 4. Emergency & Utility Suite

• SOS Panic Button: One-click access to National Emergency (112), Police (100), and Ambulance (102).
• Simulated Computer Vision: Analyzes road surface quality (Simulated for cloud optimization).
• Dark/Light Mode: Aesthetic UI with Glassmorphism design.

⚙️ Architecture & Optimization

Running complex AI and Graph computations on a free cloud tier (512MB RAM) required significant engineering optimization:

1. Dynamic Radius Calculation: The backend calculates the exact distance between points and only downloads the specific map chunk needed (clamped to 2.5km) to prevent OOM (Out of Memory) crashes.
2. Lazy Loading: Heavy libraries like cv2 (OpenCV) are only imported into memory when specifically requested.
3. Garbage Collection: Aggressive Python gc.collect() calls ensure memory is freed immediately after route generation.
