Little history of ETC
Traffic jams are caused by saturated roads, which mean that jams can be resolved by increasing the flow of traffic. Up until now, there have been active efforts to widen roads in order to alleviate traffic jams but these initiatives soon reached their limit, bringing about the need for a fundamental system reform of toll roads. This marked the beginning of the ETC project.
