Between 2002 and 2006,
SICE worked for the first time on implementing an innovative Free Flow tolling system. It was on the Central Highway and the Américo Vespucio in Santiago de Chile, where the installation and integration of all field systems for the electronic collection of vehicles was carried out without interfering with the flow of circulation. A sophisticated operational back office was also installed, allowing SICE to be at the forefront of these systems and undertake similar projects in other countries.
