How far in advance can Parknav predict availability?

Parknav's AI can typically predict availability up to 24 hours in advance with high confidence, and up to 7 days with moderate confidence.

Does it cover off-street garages too?

Parknav primarily focuses on on-street parking, but also integrates occupancy data from select off-street garages where sensors are available.

What data sources does Parknav use?

Parknav combines IoT sensor data, historical trends, city event data, and weather patterns using deep learning models to generate its predictions.
