Embodiment

[0117] In this embodiment, there are three lanes on the road 1, and five cars V1, V2, V3, V4, and V5 pass through the toll station in a free-running manner.

[0118] The present invention is a multi-lane free-flow electronic toll collection method based on precise location matching. The method includes the following steps:

[0119] step 1:

[0120] Obtain the location of the on-board electronic tag, the location of the vehicle and the image of the vehicle, and conduct electronic non-stop toll collection transactions:

[0121] The vehicle-to-road communication and electronic tag positioning subsystem transmits periodic downlink signals to the toll area through the read-write antennas M1, M2, and M3, communicates with the on-board electronic tags in the toll area, and locates the antennas A1, A2, A3, A4, A5 , A6, A7, A8, A9, A10, A11, A12 to receive the vehicle electronic tag signal.

[0122] If the vehicle entering the communication area is not equipped with an on-board electronic tag, ...

Abstract

A multilane free-flow electronic toll collection method based on accurate position match is characterized in that electronic tag positioning and vehicle position detected results are matched to achieve multilane free-flow electronic toll collection. The method comprises the following steps: 1, obtaining vehicle-mounted electronic tag positions, vehicle positions and vehicle images to perform electronic on-stream toll collection; 2, accurately matching the vehicle-mounted electronic tag positions and the vehicle positions to distinguish legal vehicles and illegal vehicles; and 3, performing background data processing, storing images, license numbers and illegal passing records of the illegal vehicles to be used as the basis of toll collection. By accurately matching the vehicle detected results and electronic tag positioning results, the judgment of the legal vehicles and the illegal vehicles is achieved, and accordingly the multilane free-flow electronic toll collection is achieved.

Description

Technical field [0001] The invention relates to the field of Intelligent Transport System (Intelligent Transport System, ITS for short), relates to a multi-lane free-flow electronic toll collection method, in particular to a multi-lane free-flow electronic toll collection method based on precise location matching. Background technique [0002] At present, many provinces and cities in my country have built the Electronic Toll Collection (ETC) system for expressways. The existing highway electronic toll collection system adopts the single-lane mode. Vehicles with on-board electronic tags need to enter the designated lane and pass the ETC lane at a low speed (the current highway ETC lane speed limit is 20km / h); for illegal entry into the ETC lane Vehicles and lane railings are automatically intercepted and handled by manual intervention. [0003] The ETC system uses ETC antennas and on-board electronic tags to realize charging transactions through wireless communication. The communic...
