Variable message traffic signalling trailer

A moveable traffic signalling trailer device, comprising

• a trailer having wheels and a supporting structure,
• a general purpose message board supported by said supporting structure of said trailer, for communicating to drivers of passing vehicles a user-selected alpha-numeric message, said message board comprising a thermostat connected to at least one cooling fan, for cooling said message board,
• an operator interface mounted on said supporting structure, for programming the message to be displayed at the site at which it is to be displayed, and
• a controller supported by said supporting structure, connected to interact with said operator interface and connected to provide the programmed message to said message board.

A moveable traffic signalling trailer device, comprising

• a trailer having wheels and adapted to be towed to a remote, exposed site and left in unattended, message-displaying operation for periods of time, and a message board supporting structure mounted on said trailer, said supporting structure including a bed and a superstructure,
• a general purpose message board supported by said supporting structure of said trailer, for communicating to drivers of passing vehicles a user-selected alpha-numeric message, said message board including a plurality of picture elements for displaying the message, said picture elements including light emitting diodes, said message board being mounted on a frame that is mounted on said superstructure so as to be moveable between a stowed position and an elevated display position,
• a lift mechanism mounted on said superstructure and connected to said frame, for raising and lowering said message board between said positions,
• an enclosure mounted on said trailer,
• an operator interface mounted on said trailer, for programming the message to be displayed, said operator interface including a keyboard for receiving on-site operator input and a full-screen CRT display for displaying the message to the operator,
• a controller supported by said supporting structure, connected to interact with said operator interface, and connected to provide the programmed message to the message board, said controller including storage for pre-determined messages, and storage for user-defined messages, said controller being adapted to display the message on said display before the message is sent to the message board, and
• a generator group for powering said message board and said operator interface.
