Abstract: A System and Method for Driver Risk Assessment through Continuous Performance Monitoring. The system and method analyzes the full sensor data stream emanating from a vehicle when being driven. The system and method is configurable to rely upon either onboard sensors or the user's smartphone to alert the data capture systems that a driving trip has started or stopped. The system relies on the data contained within the stream to generate the driver's score, rather than upon events resulting from the sensors exceeding a threshold value. The method takes the flow of data and generate scores for sub-sets of the data stream of a standard length so that each user's driving performance can be compared to other drivers being monitored by the method and system.
