What is ETC system

The ETC system (electronic toll collection system) is a fully automatic toll collection system that is widely used in roads, bridges and tunnels. It is also the most advanced highway toll collection system in the world. The toll system achieves the short-range communication between the on-board unit OBU installed on the windshield of the vehicle and the RSU on the ETC lane of the toll station, and realizes the settlement of the toll through the use of computer networking and other technologies, thereby achieving the vehicle passing the road bridge. Toll stations can pay the purpose of tolls and bridges without parking. The technology has great economic and social benefits in many aspects such as relieving traffic jams, energy saving and emission reduction, and the cost-saving management and operation costs. ETC technology is a new charging technology. The operating efficiency of ETC mode can be improved 4 to 5 times compared with MTC mode.
