Embodiment Construction

[0020] Embodiments of the present invention provide systems and methods for utilizing programmable sign displays located near traffic lights in one or more ways. Programmable signage displays provide a platform on which information can be communicated to motorists. When motorists are legally required to observe and obey traffic lights, programmable sign displays can broadcast information to large numbers of individuals on the road or nearby pedestrians. Accordingly, the programmable sign display provides an effective platform for advertising and providing public service announcements, including traffic and safety information. In addition, since most motorists have radio receivers in their vehicles, programmable sign displays can direct consumers to special radio stations that, in addition to the visual information displayed on the sign, provide Provides auditory information to motorists.

Abstract

Methods and systems use a programmable sign display located in proximity to a traffic light to provide information to motorists upon the motorists directing their attention toward the traffic light. The programmable sign display may receive programming for content to be displayed in various ways, such as through an interface to a telephone network accessible by a cell phone that sends programming information to the sign. The programmable sign may be used to inform motorists of a radio frequency upon which relevant information such as advertising or traffic reports is being broadcast. The programmable sign may be used to provide textual or graphical information, such as an instruction to motorists that relates to avoiding an approaching emergency vehicle. Additionally, management of the sign is provided to coordinate programming and control of the content being displayed. The display of content on the programmable sign display may be coordinated with the states of the traffic light to avoid distracting motorists.

Description

technical field [0001] The present invention relates to programmable signage displays. More particularly, the present invention relates to programmable sign displays located near traffic lights so that the displays provide visible information to motorists who must pay attention to the traffic lights while operating the vehicle. Background technique [0002] Traffic lights guide motorists approaching intersections, ramps, railroad crossings, etc. by indicating to the motorist whether the intersection should be passed or stopped. Motorists are required by law to obey the directions of traffic lights, and thus traffic lights can be used to coordinate the flow of traffic through an intersection. Typically, traffic lights provide a green light to instruct motorists to continue through the intersection and a yellow light (following the green light) to instruct motorists to begin slowing down in order to stop. A red light following a yellow light and preceding a green light instr...
