Abstract:
     The invention provides a double-communication region electronic nonstop fees- charging roadway system, comprising master control machine, antenna, auto railing, trigger ground sensor, snapping ground sensor, railing drop ground sensor, and 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. A double-communication region electronic nonstop fees-charging roadway method switches between communication areas according to the position of the vehicle and the trade state under the control of a roadway system, so as to let the normally trading vehicles pass or hold up the illegal vehicles. The invention can solve the vehicle following interference problem and assure the vehicle traffic speed; eliminate the communication blind areas in front of the auto railing to strengthen the ability to process abnormal conditions; reduce the vehicle following interference caused by vehicle backing and stop escaping fees；prevent viciously jumping the queue from the side road; and assure the vehicles that have traded normally pass.
