The VLU System shall announce information regarding transfers to be made at the next stop
after the phrase “Next Stop.” This shall be configurable at the time for design finalization, as well
as changeable through the provided server.
Interior Public Service Automatic or Operator-Initiated Announcement
Public Service audio messages shall be triggered automatically by a random algorithm defined
within the server or manually by the Operator by selecting from canned, pre-recorded public
service announcements.
All the public service announcements shall be stored on the on-board VLU System with the other
operational data for the entire service area. The Operator shall be able to select and play a public
service announcement from a list displayed on the Operator Interface.
Each message shall be represented by an easy to understand, text description of the
announcement. The public service announcement shall be played over the PA speakers in the
same voice as the pre-recorded ADA compliant AVA announcements.
The AVA system shall provide the capability for Automatic or Scheduled public service messages
without Operator Intervention. Agency personnel shall be able to configure the system to
automatically play public service announcements throughout the day with no operator
intervention. These announcements shall play at intervals throughout the day.
Exterior Route and Destination
The VLU System shall integrate with destination signs to automatically display the exterior
Destination messages after operator logon.
Announcement Priority
The VLU System shall control the priority of the announcements over the speakers. The
prioritization system variable shall be managed through the server system and locally via the
Operator through the Operator Interface. This feature shall control the priority of which of the two
announcements, (live Operator announcement or the automatic announcement) gets played over
the PA system speakers, in the event that they occur at the same time. The agency shall
have the ability to change the priority using the server system.
Inside Signage
The VLU System shall control and provide stop description information to the LED signs
automatically based on location based algorithms. The system shall also provide the date, time,
and Stop Requested information.
Automatic Volume Control
AVC (Automatic Volume Control) shall be provided as part of the AVA solution. AVA shall monitor
the ambient noise of the vehicle and raise and lower the volume of the automated
announcements so that it is comfortably audible over the existing noise. The announcement
volume shall be automatically compensated within a pre-defined acceptable range.
The system shall be capable of detecting ambient noise and performing AVC functions with
microphones on the inside and speakers or microphones for outside detecting. The AVC system
shall control and adjust the interior and exterior volume levels independent of one another. The
interior and exterior volumes shall have an adjustable minimum and maximum volume. The AVC
system shall adjust the volume within those set ranges. The AVC sensitivity shall also be
adjustable. The server system shall manage these adjustments and all other AVA system
