What is the minimum display time per word on a DMS phase?

The minimum display time per word on a Dynamic Message Sign (DMS) phase is established as 1 second to ensure that drivers have ample time to read and understand the message being conveyed. This duration is critical for maintaining safety on the road, as it allows sufficient time for comprehension without causing confusion or distraction while driving.

By adhering to a 1-second display time per word, DMS messages can be delivered clearly, reducing the risk of drivers attempting to read too quickly while navigating traffic conditions. The emphasis on visibility and understanding aligns with best practices in traffic management, which prioritize the safety of road users. Proper timing for message display is essential in enhancing communication through these signs, as longer or shorter durations could result in information being missed or misinterpreted, ultimately affecting driver behavior and roadway safety.
