Abstract
A traffic control system includes a traffic display for installation near or adjacent existing street signage, which illuminates the signage and displays messages relating to traffic conditions including emergency conditions or the approach of an emergency vehicle. The traffic display is associated with a camera unit, which provides redundant confirmation with a central traffic control that the display is operating correctly, and displaying the message communicated to central traffic control or at its direction. The traffic control system advises drivers of changing traffic conditions in real time, provides control of the system from central traffic control, and allows central traffic control to monitor the functioning of the traffic display.
