CrowdSynthetic is a proof-of-concept simulation for monitoring crowd density and risk in a concert-style layout.
It uses a configurable layout (zones, stage, exits) and simulates people moving, building risk, and triggering evacuation logic.

This version is a modularized version of the original POC script, preserving:

• Layout-driven geometry (layout.json)
• Capacity-based zone risks
• Trend-based prediction (“FRONT in X seconds” / “FRONT saturated”)
• AI recommendation text
• Heatmap overlay
• Custom avatar drawing
• EVAC mode logic + POC completion freeze-frame
• CSV + JSON logging of metrics

1. Install dependencies (Python 3.9+ recommended):

pip install -r requirements.txt

python -m src.main

Controls:
Q — Quit simulation
Simulation mode (NORMAL / EVACUATION) is triggered automatically based on crowd risk
Final frame is held after EVAC → NORMAL transition until you press any key
🧠 Notes:
If you get an error like cv2.error, make sure OpenCV is installed correctly.
This is a visual simulation — it opens a real-time window with avatars, heatmap, and UI overlays.
All metrics are logged to concert_risk_log.csv and concert_risk_log.json for analysis.
