ABSTRACT:
An advance notification system (10) and method notifies passengers of the 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 vehicle progress report generator (13) is employed in the BSCU (14) for permitting a passenger to solicit from the BSCU (14) via a telephone link a vehicle progress report relating to arrival of the vehicle (19) at the stop. When the vehicle (19) is approaching the stop, a time period indicating when the vehicle (19) is to arrive is specified by the BSCU (14), and when the vehicle (19) has already arrived at the stop, an arrival time is specified in the progress report.
