The scope included the substitution of the present tolling system (cash manual payment) by a mixed system that combines conventional toll lanes and ETC e-toll, and also multilane free flow (ORT).
During the renewal process both systems were working at the same time (conventional and the free flow toll).
The new system allow the vehicles with transponder DSRD (TAG) to circulate by the ORT lanes with no need to decrease the speed or stopping it. And the vehicles with no transponder must stop and pay manually (cash or bank card). This also included non-valid TAGs or with no money.
