Abstract: The disclosed subject matter provides a computing system configured to present a map-centric interface to a user, the map-centric interface usable by the user to control selected ones of a plurality of digital signs. The computing system is further configured to receive via a network interface travel data indicative of availability of travel resources, data corresponding to emergency events, and instructions from a third-party entity regarding the emergency events. The computing system is further configured to connect to a particular digital sign of the selected ones and display information corresponding to the received travel data associated with a geographic region in which the digital sign is located. In addition, the computing system is configured to display on one or more of the plurality of digital signs emergency event messages based on the data corresponding to emergency events.

Abstract: The disclosed subject matter provides a digital sign with a video camera. The digital sign and video camera are connected via a communications medium to a central computer. The central computer provides a way of changing the images displayed on the digital sign and of disseminating the video from the video camera either through real time forwarding/viewing or recording the real time video stream and playing back the recorded video to a user. The central computer also provides a user interface where an authorized user, which would normally include an authorized governmental entity, can view the video stream and unilaterally interrupt the normally displayed image (or series of images) with an emergency notification message that would display on the digital sign.
