Toll lane signing is used to guide and direct traffic through a toll lane from approximately the beginning of the impact attenuator or front edge of the toll island to the far end of the toll island. A variety of different signs have been adopted by toll agencies to accomplish this objective, including changeable message and blankout signs, in addition to the standard fixed panel, static signs, both with and without a variable display module. Changeable message signs or combination fixed and variable display module signs are predominately used to control speed through the lane by providing feedback on the user’s speed approaching the toll collection point. When considering the deployment of various toll lane signs, the desire to improve operational flow and safety along with discouraging violations needs to be tempered with user overload and toll island clutter resulting in user confusion.
