Container Port Throughput Module — Phase 193
Track container volumes (TEU) for major global ports as economic activity indicators.
Ports covered:
- Shanghai (world's largest container port)
- Rotterdam (Europe's largest port)
- Los Angeles/Long Beach (major US gateway)
Data Sources:
- Web scraping of official port authority websites
- FRED economic indicators as proxies
- UN Comtrade trade volumes
- Google Trends for port activity proxies
Metrics:
1. Monthly TEU (Twenty-foot Equivalent Unit) volumes
2. Year-over-year growth rates
3. Port congestion indicators
4. Economic activity correlation
Monthly updates based on port authority reporting schedules.
Phase: 193
