Portable Changeable Message
Signs
PASSAGE currently has eight
portable dynamic message signs to advise drivers of
conditions where driver action is required. The signs
are placed where drivers can see them in advance
to take the proper action. Messages displayed on the
signs are sent by the operators at the TMC directly to
the sign in the field, and can be modified at any time
to tailor the message to current field conditions.
