N2 - In these years, electronic toll collection (ETC) system has developed rapidly in China. However, adjacent-lane communication interference has become a serious problem for high vehicle density case. In this paper, the field distribution of the communication zone of ETC system is simulated by hybrid FDTD-PO method. Firstly, the roadside unit (RSU) antenna is simulated by the FDTD method. Secondly, the field distribution of the communication zone around the onboard unit (OBU) is obtained by the PO method based on the near-field data of RSU antenna. To investigate the adjacent-lane communication interference in detail, three kinds of RSU antennas are considered and the field distributions on multi lanes are compared with the theoretical results.
