What is the maximum cycle time of a two-phase message on a DMS?

The maximum cycle time of a two-phase message on a Dynamic Message Sign (DMS) is 8 seconds. This means that the DMS can display a message for a duration of up to 8 seconds before it cycles to the next phase or message.

Understanding the cycle time is crucial for effective communication with drivers, as it affects how quickly information can be updated and the response time of drivers to the displayed messages. A cycle time that is too long could result in drivers not receiving timely information, while a cycle time that is too short may lead to confusion as drivers may not have enough time to process the information being presented before it changes.

This maximum of 8 seconds is established to ensure that the information remains clear and actionable for the viewing audience, striking a balance between information dissemination and comprehension.
