Description

TECHNICAL FIELD

[0001] The present application relates to the field of expressway electronic communication technology, more particularly, to an ETC gantry system precise toll collection method. BACKGROUND

[0002] Currently, an ETC gantry system will be built in the expressway section to collect fees from the passing vehicles through the ETC gantry system. The ETC gantry system includes but is not limited to RSU, high-definition camera and other devices, and the RSU is used to trade with the on-board terminal (OBU or CPC) in the passing vehicle to achieve the purpose of real-time toll collection or charging for the vehicle, so as to realize the segmented charging for the ETC vehicle and the segmented charging for the MTC vehicle.

[0003] Generally, the expressway has two adjacent lanes in one direction, and only a row of green belt is used for isolation in the middle. The adjacent lanes in two directions are easy to cause the radio frequency signal of the RSU in the ETC gantry system of the lane in the direction to cover the adjacent lane in the opposite direction, thereby causing the vehicle in the opposite direction to trade with the RSU in the lane in the direction and resulting in the error toll collection. The main solutions to solve the problem of error toll collection in the opposite direction currently include: reducing the signal strength of the RSU to make it cover only the lane in the direction, and establishing a signal shielding wall of the RSU in the middle green belt. However, the solution of reducing the signal strength of the RSU can reduce the problem of error toll collection in the opposite direction to a certain extent, but the effect is limited, and the reduction of the signal strength will affect the transaction success rate of the vehicle in the lane in the direction. The establishment of the signal shielding wall in the middle green belt will greatly increase the construction cost of the ETC gantry system, and will also increase the subsequent maintenance workload and difficulty.
