The majority also noted that safety and Public Service Announcements (PSA) messages on Dynamic Messaging Signs (DMS) are useful, with some even noting that those messages are more effective on DMS as compared to other media (such as television).

In addition, the perceived usefulness of safety and PSA messages was examined in a binary logit model. The model showed that the messages were considered useful if the driver encountered them often. Respondents also thought that those messages could be effective in changing behavior. Hence, greater exposure to such messages impacts the perceptions of the messages.
