EBBs and Driversafety - Research Report
I just came across a final report about the following research in 2001 by the Human Centered Systems Team Office of Safety Research and Development Federal Highway Administration:
Research Review Of Potential Safety Effects Of Electronic Billboards On Driver Attention And Distraction
Advances in display technology and decreases in cost have created interest to expand the deployment of high resolution and dynamic imaging. The introduction of such technology to billboards, where static displays of advertising have been the standard, raises questions on the effects that electronic billboards (EBBs) may have on drivers' attention. Based on conversations with government staff and examination of state regulations, the literature review summarized state billboard regulations and policies relevant to EBBs and tri-vision signs. The review then encompassed billboard-related crash analyses and potential safety factors such as distraction, conspicuity, and legibility. Due to the limited amount of research regarding external distraction in drivers, internal distractions, such as in-vehicle information systems and cellular telephones, were used as surrogates when investigating how potential distractions affect the driver. Roadway characteristics that were recognized for future research in the knowledge gap section include horizontal and vertical curves, intersections, work zones, and EBB billboard spacing. EBBs and tri-vision sign characteristics and their proposed research questions are related to an EBB's message content and comprehensibility, exposure time, motion, and sign maintenance. Finally, research questions related to driver characteristics are directed to age and route familiarity.
