This article describes a major pilot project in the Alps, to test Austria's plans to introduce a system of tolls for its motorway network. The state-of-the-art Funkmaut tolling system has been installed, about 100km from Salzburg, by the Swedish company Combitech Traffic Systems and its Austrian partners Gesig and Skidata. Basically, Funkmaut is a free-flow microwave toll-debiting system, allowing vehicles, with a special small window-mounted on-board unit (OBU), to drive through a toll booth without using cash and without stopping. The Funkmaut project's main purpose is to prove the feasibility and desirability of debiting vehicles via a 5.8MHz (European standard) microwave link between a gantry-mounted transceiver and the OBU. The OBU acts as a transceiver, and is equipped with a smart card which contains contracts and can be loaded with an electronic value. The Austrian highway and motorway company, OSAG, which awarded the project's contract, has set some specific tasks for Funkmaut: (1) it must blend into the existing system; (2) its concept must be verified for free-flow high-speed single and multiple lane configurations; (3) it must have a vehicle classification system; and (4) it must pass licence plate checks using video cameras.
