To solve the problem of adjacent lane interference, there different ways were proposed. 1) modeled the ETC lane and established coordination system, method of boundary analysis was adopted to calculate the parameters for ETC lane. 2) D-S evidence theory was adopted to fuse the results of verification and make a final decision whether it was the right car to be charged 3) Used coherent demodulation method for reducing the signal of the adjacent lane, avoid the adjacent lane interference. The experimental results show that: 1) with reasonable installation conditions, set the ETC lane parameters, can guarantee the reliable trading in effective communication area. 2) Information fusion technology can highly reliably detect illegal vehicles and solve adjacent lane interference in ETC system, 3) Coherent demodulation method has large improvement in signal de-noising and system error rate.
