Kapsch TrafficCom says that it has now reached 1.6 billion multi-lane free-flow (MLFF) transactions per year across nine urban highways in Santiago, capital of Chile.
Autopista Central, the city's north-south highway which opened in 2004, accounts for almost a third of all transactions in the South American country.
Penetration of in-vehicle tags among motorists is high - Kapsch says there are four million tags in a city of just seven million inhabitants - with revenue generated playing "a pivotal role in supporting urban infrastructure in Santiago".
As well as easing congestion and smoothing vehicle flow, Kapsch says MLFF "also plays a role in decreasing carbon emissions, reducing travel time, and fostering a more sustainable urban environment".
The company delivers two billion MLFF transactions annually in Chile overall, with Santiago accounting for the lion's share.
"Managing traffic in a bustling city like Santiago is paramount," says Carlos Wiedmaier, VP for solution consulting Latin America at Kapsch TrafficCom.
"Our MLFF solution not only ensures efficient tolling but also supports the broader urban infrastructure."
