Abstract:
    The invention provides a double-communication region electronic nonstop fees- charging roadway system, comprising a master control machine, an antenna, an auto railing, a trigger ground sensor, a snapping ground sensor, a railing drop ground sensor, and a fees number display where the antenna comprises two groups of wireless communication devices with different emitting angles, interconnected through logic processing circuit, and is installed on a gantry and above the roadway, where the far and near communication areas covered by the two groups of wireless communication devices are overlapped. The invention can solve the vehicle following interference problem and assure the vehicle traffic speed, and can eliminate the communication blind areas in front of the auto railing to strengthen the ability to process abnormal conditions, and can reduce the interference caused by making cars back, and assure the road with no traffic block, and reduce the following interference caused by vehicle backing prevent viciously jumping the queue from the side road, and assure the vehicles that have traded normally pass.
