Permanent structures narrower than the existing pavement are recognized highway hazards. Information has been published to demon­ strate the seriousness of the hazard, but little has been done about the effectiveness of various types of warning signs and pavement markings used to safeguard such locations.

Studies of visual effects of road signs have shown that having dynamic imagery, and even better, animation, helps improve road signs as it increases a viewer’s attentiveness. However, currently existing animated imagery signs, which are usually digital billboards, have drawbacks including distraction caused by bright LED lights, large energy consumption, and expensiveness. To overcome the probl...
