Azuga obtains posted speed limit data of road segments from third-party solution providers. The speed limit databases of these vendors are a highly accurate tool for identifying patterns in high-risk driver behavior. The database is built upon the highest quality map information available and is updated around the clock to reflect the latest changes to posted legal speed limits, new road construction and online feedback from users.They also use proprietary dynamic error detection and correction techniques to address the inevitable errors that occur in vehicle engine data (ECM), GPS receivers and digital map data.
