<br />While the Zeigarnik effect may be present in a wide variety of driving situations, possible <br />scenarios that could affect drivers include: <br /> <br />. A scrolling message requires the viewer to concentrate as the message is revealed. <br />Based on the size and resolution of the sign, and the length of the message, this could <br />range from less than one second to many seconds. <br /> <br />. A sequence of images or messages that tell a story, during which the driver's <br />attention may be captured for the entire duration that the sign is visible. Instead of <br />merely glancing at the sign and then returning concentration to the driving task, more <br />attention may be given to the message, <br /> <br />. Anticipation of a new image appearing, even if the expected new image is not related <br />to the first image, In this case, the driver may be distracted while waiting for the <br />change. <br /> <br />Federal Highway Administration <br />Safety and Environmental Design Considerations in the Use of Commercial <br />Electronic Variable-Message Signage (Wachtel & Netherton, 1980) 11 <br /> <br />This research provides information on the use of on-premise Commercial Electronic <br />Variable-Message Signs (CEVMS) that display public service information (i.e,. time and <br />temperature) and advertising messages along the Interstate highway system. The <br />research found the following major considerations: <br /> <br />. Highway Safety Considerations <br />The link between changing messages that attract drivers' attention and crashes has <br />been an issue of concern since the earliest forms of electronic signage became <br />available. This study thoroughly reviewed the literature seeking information <br />regarding a potential link between CEVMS and crashes: <br /> <br />"Although a trend in recent findings has begun to point to <br />a demonstrable relationship between CEVMS and <br />accidents, the available evidence remains statistically <br />insufficient to scientifically support this relationship. " <br /> <br />The study also noted that studies have not documented information about "such <br />occurrences as 'near misses' or traffic impedances that are widely recognized as <br />relevant to safety, and which mayor may not be attributable to the presence of <br />roadside advertising." <br /> <br />. Human F actors Considerations <br />Human factors relate to all the elements that explain driver behavior, such as eye <br />glances and driver responses to a variety of driving-related stimuli, The study makes <br />the point that simple driving-related tasks consume relatively little information <br />processing capacity, However, when other conditions, such as congestion, <br />complicated roadway geometries, or weather are also considered, the marginal extra <br /> <br />~11 <br />
