The invention relates to the technical field of highway tolls, and in particular relates to a highway intelligent toll system based on big data. A lane toll system comprises an entrance lane subsystem, an exit lane subsystem and a toll data clearing center. The entrance lane subsystem comprises an entrance computer, an automatic card issuing machine, an entrance camera, an entrance vehicle position sensor, an entrance speech player and an entrance gate controller, wherein the automatic card issuing machine, the entrance camera, the entrance vehicle position sensor, the entrance speech player and the entrance gate controller are electrically connected with the entrance computer. The exit lane subsystem comprises an exit computer, an automatic card collector, an exit camera, an exit vehicleposition sensor, an exit speech player, a mobile toll gateway, a code scanner and an exit gate controller, wherein the automatic card collector, the exit camera, the exit vehicle position sensor, theexit speech player, the mobile toll gateway, the code scanner and the exit gate controller are electrically connected with the exit computer. The toll data clearing center communicates wirelessly withthe exit computer, receives toll records and carries out clearing in real time. The system prevents fake plate vehicle from driving on a highway by collecting the face data of license plates. Throughautomatic pass card issuance and automatic toll accounting, the highway traffic efficiency is effectively improved, and the labor cost is reduced.
