This article proposes a procedure for the design of the layout of toll plazas in order to subsidize the implementation of these in new highways concessions or improving existing ones, aiming at a better level of service to the highway user. A computer program prototype was developed for defining the characteristics of the toll plaza from a desired level of service. For that, initially, this article presents a characterization of toll plazas about payment type, location of the plaza in the highway system, the layout and the main elements of design. Based on these analyses, a procedure is proposed for dimensioning toll plazas considering the relationship between toll plazas' characteristics and the desired level-of-service to the highway user.
