The invention provides a novel and rapid highway toll system and device which are applied to an intelligent mobile terminal, a backend server and barrier gate control apparatuses. Firstly, a mobile terminal user registers user information and registers vehicle information. As the registration is conducted, the backend server verifies registration information. The intelligent mobile terminal acquires current position information of the vehicle by invoking a third party API, stores the current position information and uploads the vehicle information to the backend server. The backend server, based on the reported geological coordinate, computes the accumulated mileage from different toll stations, and based on the accumulated mileage, computes how much the vehicle should pay. The barrier gate control apparatuses which are installed at the toll gates real-time capture a plate number of the vehicle, identify the captured images of the vehicle, and transmit the identified plate number to a barrier gate control center for controlling barrier gate devices. According to the invention, by rapid plate number identification, rapid charging, and automatic deduction, the system greatly reduces traffic congestion at toll gates, obviates the need for the vehicle to install hardware, can provide detailed deduction record, and greatly improves user experience.
