However, in urban areas, there is no land for preparing a tollgate and it may adopt a uniform rate system. In this case, feelings of inequality arise to a user. Then, in a main line top or an exit ramp, the flexible fee collection system using a free flow antenna is realized. However, compared with the radio system of a tollgate, the rate of incidence of the abnormalities in communication is high.
