Generally, there are two types of charge collection on toll roads. One is a method that is commonly used, in which the toll collector is waiting at the end point on the toll road, which is called the toll gate, and calculating the toll with the right of passage issued from the point of view. And the fee is collected by wireless communication with the communication device installed in the mobile communication terminal.

In this case, the charge collection by wireless communication can be charged without decelerating or stopping the vehicle, and the vehicle lag in the tollgate can be greatly reduced, such as when the charge collector collects the charge.

Such a wireless charging system is also called an Electronic Toll Collection System (ETCS), and is called a high pass system because it passes without stopping.

The electronic fare collection system has a single lane system that requires space for installing various equipment and manned booths, which is similar to the existing fare collection system, and is called Traffic Island. Unlike the single lane system, There is a multi-car way, which is a way in which there is no movement between the lanes because there is not.

Currently, the electronic fare collection system is installed in a toll gate of a toll road such as a highway, and a vehicle terminal ('OBU') mounted on a toll road vehicle and a roadside device installed on a road side for collecting a toll (DSRC), which is a system in which a user enters a vehicle that supports a service by attaching a vehicle terminal to a vehicle. Thereby obtaining the data of the authenticated card and the inputted vehicle through the communication between the vehicle terminal and the roadside apparatus, whereby the toll collection is performed.
