What is the lesser value between display time per word or units of information for a DMS phase?

• A. 1 second
• B. 1.5 seconds
• C. 2 seconds
• D. 3 seconds

Answer: (C)

The lesser value between display time per word and units of information for a Dynamic Message Sign (DMS) phase effectively determines how long information is displayed to drivers. In optimal conditions for readability, the recommended display time per word is typically about 1.5 seconds. However, for more complex messages, this can be adjusted.

Choosing 2 seconds as the lesser value can often align with guidelines for ensuring that motorists have enough time to absorb the information without causing confusion or risk. DMS phases need to balance between clear communication and maintaining safe traffic flow, so understanding the timing for display is crucial.

In this context, 1 second, 1.5 seconds, and 3 seconds would not constitute the lesser value for displaying information compared to 2 seconds. Thus, 2 seconds becomes the most reasonable choice, allowing for a good compromise between quick display and comprehensibility for those navigating roadways.
