Abstract
An advance notification system (10) and method notifies passengers of impending arrival of a transportation vehicle (19), for example, a school bus, at a particular vehicle stop. The system (10) generally includes an on-board vehicle control unit (VCU) (12) for each vehicle (19) and a base station control unit (BSCU) (14) for making telephone calls to passengers in order to inform the passengers when the vehicle (19) is a certain predefined time period and/or distance away from the vehicle stop. The VCU (12) compares elapsed time and/or travelled distance to the programmed scheduled time and/or travelled distance to determine if the vehicle (19) is on schedule. If the vehicle (19) is behind or ahead of schedule, the VCU (12) calls the BSCU (14), which then adjusts its calling schedule accordingly. Significantly, a preset notification time period mechanism (9) in the BSCU (14) permits the passenger to contact the BSCU (14) in order to define a preset notification time period when the passenger is to receive a telephone call prior to arrival of a vehicle (19) at a vehicle stop to thereby indicate impending arrival of the vehicle (19) at the stop.
