Successful transportation messages are only effective if travelers can read and comprehend the message. However, text-based messages can be challenging for non-native English speakers or slow-reading populations, such as the elderly. The addition of graphics messages as a potential aid to improve message comprehension is uncertain, as is their effectiveness compared to text-only messaging campaigns. Current literature reviews have focused on the use of graphical shields and highway signs for messaging, but research is needed to analyze the effectiveness of graphics for conveying safety messages without explanatory text and evaluate whether this approach could be beneficial for specific populations. The objectives of this project were to determine whether graphics can be used to enhance comprehension and effectiveness of messaging, and to help guide development of guidelines to determine when and how the graphics, either stand-alone or supplemental to text, can be used to enhance the comprehension and effectiveness of key safety messages.
Successful transportation safety messages are only effective if travelers can comprehend the notices. However, one method of safety messaging, text-on
