Abstract

Systems and methods for providing real-time road condition information using a network of sensor-equipped vehicles. The system includes a plurality of vehicles equipped with dash cameras and other sensors that collect road condition data. A spatiotemporal index maintains processed sensor data associated with road segments, where personally identifiable information is removed and data quality is validated. The system analyzes the sensor data to detect various road network conditions including weather conditions, construction zones, and infrastructure status. The system monitors data freshness and automatically triggers collection of updated data when existing data exceeds age thresholds. User account information customizes the display of road conditions based on vehicle types and regulatory requirements.
