Application of High Speed ​​ETC Technology

High-speed ETC technology is the electronic toll collection system. Compared with RFID systems, this technology is more advanced. It is the world's most advanced and advanced toll system and is widely used in highway toll collection areas. It is used in the toll of roads, bridges, and tunnels. It is also very popular. When passing vehicles pass through a crossing, there is no need to stop, that is, the automatic identification of vehicles and automatic charging can be realized.

High-speed ETC technology mainly involves automatic vehicle identification technology, automatic vehicle classification technology, short-range communication technology, evasion snapshot system technology, infrared technology, etc., from the background system, lane controller, RSU (roadside unit, commonly known as card reader, usually It is installed on the top left of the vehicle and the OBU (the onboard unit, commonly known as the vehicle card, is generally fixed directly above the windshield). The OBU uses DSRC technology to establish a microwave communication link with the RSU. Under the condition that the vehicle does not stop, the system will automatically carry out actions such as vehicle identification, electronic deduction, and so on, so as to realize no-stop, exempt card, and establish unattended vehicle access.
