Abstract

An automated, location-based, dynamic notification system comprises a mobile unit hardware device and a control center computer facility with communication capabilities. The mobile unit comprises a position module, a location processor, an action processor, a data module, and an I/O module. The control center comprises a system processor, a communication module, and a master database. The system provides notifications of arriving, approaching, leaving, entering, and any other types of location-related notifications, which are issued in an automatic, unattended manner. The illustrated embodiments of the invention are based on location and thus are used in a dynamic routing situation where both route patterns and stop locations change frequently while the object is moving. The system requires no interaction from the driver or the dispatcher, requires no on-board checking or manipulation of a schedule, and applies in many situations including special-education transportation, prisoner transportation, airport shuttle service.
