The growth in design, construction, and operation of toll facilities is a trend in the United States. Few toll plaza design guidelines exist and now with the implementation of electronic toll collection, proper and safe toll plaza design is even more critical. Toll plaza pavement markings and tollway signs were identified in previous research as those in need of design guidelines. This research explores toll plaza design guidelines for tollway pavement markings and signs. Current design publications with pavement marking and sign guidance are limited to the available versions of the Manual On Uniform Traffic Control Devices (MUTCD). The MUTCD does not adequately provide the necessary guidance to design these aspects of the toll plaza. Current practices from 13 toll authorities in the United States have been studied and assessed, a panel of toll plaza design experts has been assembled to provide review, and toll plaza pavement markings and tollway sign design guidelines are recommended.
