STRUCTURE OF THE MESSAGE ON THE CHANGEABLE MESSAGE SIGN (CMS)

Researchers at the Visual Detection Laboratory at the University of California, Berkeley, have been studying ways to optimize the presentation of changeable message signs (CMS) on roadways. These signs, also known as variable message signs (VMS) are being used to aid in traffic control as well as in providing driver information alerts. Through laboratory-based examinations of how message structure can impact its intelligibility, researchers have studied ways to match CMS content to the visual needs of drivers. Areas of focus include recall, duration of message, and layout of the message. Using results from laboratory testing, researches are now positioned to conduct field tests of proposed improvement strategies.
