ETC is a non-stop electronic toll collection system, and ETC lanes are used by vehicles equipped with ETC on-board equipment.

ETC (Electronic Toll Collection) system is the most advanced road and bridge toll collection method in the world. The vehicle-mounted electronic tag installed on the windshield of the vehicle communicates with the microwave antenna on ETC lane of the toll station in short distance, and the computer networking technology is used to make background settlement with the bank, so that the vehicle can pay the road and bridge fees without stopping at the road and bridge toll station.

ETC is an electronic automatic toll collection system for expressway, bridges and tunnels that is being developed and popularized internationally. This technology has a long history of development abroad, and the electronic toll collection systems in many countries and regions such as the United States and Europe have been partially networked, and economies of scale have gradually formed. In China, the road network charging method based on IC card and magnetic card and manual charging is undoubtedly affected by this trend.
