where the toll rate is determined by the distance traveled or number of exits passed. Some highways use coin-drop machines on toll plazas. For toll roads whose ramps have no toll plazas, it is possible to exit the toll road before the mainline toll plaza, use local streets to bypass it, then re-enter the highway via an interchange on the other side of the toll plaza. Thus it is possible to drive on some barrier toll roads while paying less or not paying at all; this is the basis of the "open" descriptor. There are two main methods by which planners may prevent such toll evasion. One method is to simply remove highway entrances after and exits before toll plazas, so that detouring around toll plazas becomes such an inconvenience that most users will not bother. Another method is to place toll plazas on exits before and entrances after mainline toll barriers, so that all users will always have to pay at least one toll, regardless of entry or exit point. The second method is sometimes called a "barrier-ramp" system; it can be deemed open or closed, respectively, depending upon whether it is consistently applied to all entrances and exits, or only some of them. Examples of the second method may be found on the
