Crowd Data & Recommendations Disclaimer

Effective: 11 March 2026
⚠ Important — Please Read Before Relying on MetroCrowd Data
MetroCrowd crowd levels, coach recommendations, and route suggestions are estimates only. They are not guaranteed to be accurate. Always make your own assessment of safety and conditions when travelling on the Delhi Metro.

1. Nature of Crowd Data

MetroCrowd generates crowd level estimates using two sources:

  1. Machine learning predictions: statistical models trained on historical Delhi Metro ridership patterns. These predict likely crowd levels based on time of day, day of week, station tier, and historical trends. They do not reflect real-time conditions.
  2. Community reports: crowd level observations submitted voluntarily by MetroCrowd users. These reflect a single user's subjective assessment at a specific time and may not represent current conditions.

The crowd percentage displayed is a weighted blend of these two sources, updated approximately every 60 seconds during operating hours. It is inherently a lagging indicator.

2. Accuracy Limitations

3. Coach and Gate Recommendations

Coach recommendations (e.g., "Board Coach 4") are generated from historical crowd distribution models and gate-to-coach proximity data. They do not account for:

4. Your Responsibility

By using MetroCrowd, you acknowledge that:

5. Limitation of Liability

To the fullest extent permitted by applicable law, MetroCrowd is provided "as is" without warranties of any kind. MetroCrowd shall not be liable for any direct, indirect, incidental, special, or consequential damages arising from reliance on crowd data, coach recommendations, or route suggestions. The total liability shall not exceed the amount you have paid to use the Service in the preceding 12 months (which, as the Service is currently free, is zero).

6. No Endorsement by DMRC

Independence Notice

It is not affiliated with, endorsed by, sponsored by, or officially connected to Delhi Metro Rail Corporation (DMRC) or any government authority.

7. Data Source Attribution
