Embodiments of the present disclosure include vehicle safety monitoring, and more particularly monitoring a condition of an operator of a vehicle. According to some embodiments, the present disclosure includes a system for alerting the operator and/or a remote server/user when the operator's driving time violates a pre-determined maximum threshold. According to other embodiments, the present disclosure includes a system that compares an operator's driving behavior against a personalized driving model, and generates a flag based on that comparison. In some cases, this comparison can help detect when the driver is exhibiting signs of fatigue or other kinds of impairment. According to other embodiments, geographic information may be used to improve road safety systems.

Vehicle safety and driver condition monitoring, and geographic information based road safety systems

A method for vehicle data management according to embodiments of the present invention includes receiving an accelerometer signal from an accelerometer mounted in a vehicle, determining an accelerometer specific force based on the accelerometer signal, receiving a speed signal from a speed sensor or GPS or other source on the vehicle, wherein the speed signal indicates a speed of the vehicle, determining an instantaneous acceleration of the vehicle by calculating a rate of change of the speed based on the speed signal, selecting a current observed acceleration as a lower value of the accelerometer specific force and the instantaneous acceleration, capturing video footage with a camera mounted on the vehicle, and flagging the video footage corresponding to a time when the current observed acceleration exceeds a preset safe force value.
