US Patent 10573184 Monitoring security threat during travel

An approach for notifying a passenger of a route deviation during travel. The approach includes calculating a passenger route deviation from a predicted travel route and comparing the passenger route deviation to a predefined threshold route deviation. The approach further includes providing the passenger a notification of a route deviation if the deviation exceeds a predefined route deviation threshold. In addition, the approach determines if the passenger acknowledged the route deviation notification within a predetermined time period and if the passenger fails to acknowledge the notification, then provides the notification to one or more third parties.
