Improved Work Zone Portable Changeable Message Sign Usage

Portable changeable message signs (PCMSs) are an important part of traffic control within many Texas work zones . When used properly, these signs can command good attention from motorist, provide important information about current and future roadwork activities, and help motorist make proper driving decisions. When used improperly, however, they quickly lose credibility with the motoring public and contribute to motorist confusion. In this project, researchers developed specific, user-friendly implementation guidelines that will assist field personnel in selecting and using proper portable changeable message sign messages in work zones on a day-to-day basis.
