ABSTRACT:

A display control device, including an electronic control signal, coordinates the advertising display device with the traffic control signal device to make the advertising message invisible to drivers at selected times, particularly during transitions of the traffic control signal device from one signal phase to another, during a particular phase, and for predetermined time intervals before or after the transition from one phase to another, as desired or appropriate to display the advertising message only during times of the traffic control signal device phases when drivers' attentions to the advertising message will not adversely affect the drivers' attentions to required driving functions.
