The Buenos Aires government has described the implementation of a free-flow electronic toll concession system on highways in the capital as a success.
The Aupass system, run by state-owned concessionaire AUSA, had attracted 20,000 users as of December 31, according to the Buenos Aires city website.
The new system was launched in November and uses a bar-coded sticker, which was offered free of charge through end-December.
The sticker costs 70% less than the transponder that was previously used on the highways. It requires no batteries and is destroyed on removal, which makes it more efficient and discourages theft.
The system is in place on highways Perito Moreno, 25 de Mayo and AU Illia. For now, the electronic payment lanes will be able to read both transponders and stickers.
