T3 Webinars are brought to you by the Intelligent Transportation Systems (ITS) Professional Capacity Building (PCB) Program of the U.S. Department of Transportation's (U.S. DOT) ITS Joint Program Office (JPO). References in this webinar to any specific commercial products, processes, or services, or the use of any trade, firm, or corporation name is for the information and convenience of the public, and does not constitute endorsement, recommendation, or favoring by the U.S. DOT.


Transportation agencies are frequently asked to post safety and public service announcements (PSAs), such as seat belt laws or announcements concerning upcoming events on dynamic messages signs (DMS) when they are not being used for transportation-related purposes. However, there are some concerns that these messages are not understood by travelers and may actually be a distraction. Further, the effectiveness of such messages in influencing motorists’ travel behavior and actions is not well understood.

This webinar will present the results of “Public Perception of Safety Messages and Public Service Announcement on Dynamic Messages Signs in Rural Areas” report. The report addressed a number of questions related to safety awareness and PSA messages on DMS, including traveler awareness, understanding, changes in behavior, and opinions. We will discuss the results of Intercept surveys that were conducted at rest areas and truck stops to collect public feedback regarding safety messages and PSAs on DMS posted by five agencies in four study corridors.
