Can developers install etc in the property? Is there a charge?

Etc can only exist in high-speed toll stations, and developers cannot use high-speed etc in properties. This is illegal. And there is no charge.

ETC, Chinese translation is electronic toll collection, which is an automatic toll collection for highways or bridges. 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 a special short distance, and the computer networking technology is used to make background settlement with the bank, so that the vehicle can pay the highway or bridge toll without stopping.
