A comprehensive web-based traffic flow simulation built with Python (Flask backend) and JavaScript (frontend visualization).It features Zimbabwe-style traffic light systems, advanced collision detection, predictive safety measures, and real-time parameter adjustment for sensitivity analysis. # Traffic Flow Simulation - Python-based Computational Model A comprehensive web-based traffic flow simulation built with Python (Flask backend) and JavaScript (frontend visualization). Features Zimbabwe-style traffic light systems, advanced collision detection, predictive safety measures, and real-time parameter adjustment for sensitivity analysis. ## Features ### 🚗 Road Configurations - **Two-Way Road**: Opposing traffic lanes with strict lane discipline - **Crossroad**: 4-way intersection with Zimbabwe-standard traffic light control ### 🎯 Advanced Safety Systems - **Collision Detection**: Real-time bounding box collision detection - **Crush Prediction**: Cars calculate time-to-collision and brake preemptively - **Safe Following Distance**: Automatic 2-second rule + minimum gap maintenance - **Emergency Braking**: Multi-level braking system based on threat level - **Adaptive Cruise Control**: Cars match speed of vehicle ahead when in comfort zone ### 🚦 Zimbabwe-Style Traffic Light System - **RED**: Mandatory stop - no exceptions - **AMBER**: Stop if safe to do so (calculates stopping distance vs distance to line) - **GREEN**: Proceed normally - **All-Red Phase**: Both directions red for 1 second during transition (intersection clearance) - **Proper Sequencing**: Green → Amber → Red → All-Red → Other direction Green ### 📊 Adjustable Parameters 1. **Number of Cars** (5-50): Control traffic density 2. **Max Speed** (1-10): Set speed limit 3. **Acceleration** (0.1-1.0): How quickly cars speed up 4. **Deceleration** (0.1-2.0): Braking strength 5. **Minimum Gap** (10-100px): Base safe following distance 6. **Reaction Time** (0.1-2.0s): Driver response time for 2-second rule 7. **Green Light Duration** (2-10s): How long green phase lasts 8. **Amber Duration** (1-5s): Warning time before red ### 🎨 Visual Features - **Safety Zones**: Green highlighted zones showing safe following distance - **Brake Lights**: Red lights activate when car is stopped or slowing - **Hea …
