Abstract
Exemplary embodiments of the present invention are directed to a system for monitoring, recording, and analyzing driver activity. An exemplary system comprises a sensor module configured to receive data from one or more sensors that measure acceleration or deceleration associated with a vehicle. A stop detection module is configured to receive the sensor module data, process the sensor module data, and determine an abrupt acceleration or deceleration event. A location module is configured to retrieve the location of the vehicle simultaneous with an abrupt acceleration or deceleration event. The system stores the location of the abrupt acceleration or deceleration event in an event record in an event database.
