This document describes a case study of an insurance company implementing a pay-how-you-drive model using telematics data from sensors in vehicles. The insurance company analyzes driving data like speeding, hard braking and acceleration to better assess customer risk and set premiums based on actual driving behavior rather than group projections. The company implemented a Hadoop data platform to process large volumes of sensor data to gain insights into driving patterns and identify high-risk behaviors to improve risk assessment and customer segmentation.
