What does PCMS stand for in traffic management?

PCMS stands for Portable Changeable Message Signs, which are versatile traffic management tools used to convey important messages to drivers. These signs are often deployed in various locations to provide information about road conditions, construction updates, detours, and safety warnings. Their portability allows for easy relocation to adapt to changing traffic situations, making them effective for both temporary and permanent roadway management. The use of portable signs enhances driver awareness and helps to improve overall traffic safety.

Perpetual Changeable Messaging System is not a recognized term in the context of traffic management. Private Changeable Message Signs may refer to signs intended for private property or specific organizations but do not encompass the broader application and recognition of Portable Changeable Message Signs in public traffic management.
