Abstract
Portable traffic message signs configured for use on or near roadways, highways, sidewalks, and/or other travel routes. The portable traffic message sign may be configured to provide instructions, warnings, alerts, and/or other information for travelers. In some embodiments, the portable traffic message sign may be configured to be adaptive in response to sensed weather, traffic, and/or other conditions. For example, the portable traffic message sign may have a controller determining suitable message content to display, the message content reflecting a present traffic and/or weather condition. Moreover, the message sign controller may select, based on a speed of travel of traffic, words, phrases, and/or pages to display the message content such that the message may be perceivable by oncoming travelers. The controller may control height, angle of rotation, and/or other orientation parameters of the message sign toward a point of aim in order that the message may be perceivable by travelers.
