VIA VERDE (GREEN LANE) NON-STOP TOLLING SYSTEM

This paper describes two phases of a non-stop tolling system. Since April 1991, BRISA has been operating 12 nonstop tolling lanes installed in 4 main toll plazas around Lisbon, using "read only" tags. Forty percent of the total traffic uses these automatic lanes. This was phase one--an "open" toll system. The second phase of the project, to be implemented by September 1996, required more advanced technology. It consists of the extension of the nonstop tolling system to the whole Portuguese highway toll network, with a present total length of 500 km increasing to 780 km in 1997. All toll plazas have automatic tolling lanes. Tags are "read/write" and the frequency is the European standard--5.8 GHz. All automatic exit lanes have no barriers and are equipped with video enforcement. Within this nonstop tolling "closed" system, vehicles are identified at the entry lanes and information stored in the tag are read by the exit antenna transmitting them in real time to several plaza computers, connected to a central computer. The number of subscribers is now 140,000 and the target is 350,000 by the end of the year. Toll taxes are automatically charged on the client's bank account.
