BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-

[0001] The present invention relates to a multi-tariff based tariff device using WAVE communication, and more particularly to a multi-tariff based tariff device using WAVE communication, .

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 bill collection system by wireless communication is also called an electronic bill collection system, and is also 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 communicates with the terminal of the vehicle through DSRC (Dedicated Short Range Communication) communication and collects the charge.

Recently, WAVE (Wireless Access in Vehicular Environment) has been widely developed as a vehicle communication technology for intelligent ITS (Intelligent Transportation Systems).

WAVE communication technology is an abbreviation of wireless connection for vehicle environment. Vehicle communication using WAVE communication is mainly used for inter-vehicle communication, vehicle-to-vehicle communication (V2V), vehicle- -to-Infra). This configuration allows communication between On-Board Equipment (OBE) in the vehicle and Road Side Equipment (RSE) Lt; / RTI >

OBE (hereinafter, referred to as 'OBE') having a WAVE communication function receives traffic information, road state information, and other useful information from the on-road base station, and the vehicle transmits its own vehicle-related information to the on- Vehicle-to-base-station communication. At this time, the on-road base station receives traffic information, road condition information, and other useful information through communication with a control center such as a traffic information server, a traffic situation information server, and the like, and provides it to OBE of the vehicle.

In addition, the OBE of the vehicle performs inter-vehicle communication such as prevention of a collision by transmitting a warning message to surrounding vehicles when a problem occurs in the vehicle of the vehicle, thereby utilizing the WAVE communication technology, And transmits and receives the information to and from the on-road base station and the surrounding vehicles, and performs an interface with the user.

On the other hand, when a multi-car based electronic fare collection system is constructed through the WAVE communication method, the transmission capacity is improved by more than 10 times as compared with the currently used DSRC (Dedicated Short Range Communication) method, Which is highly appreciated.
