Embodiment

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

[0118] The present invention is a multi-lane free-flow electronic toll collection method based on accurate position matching, and the method comprises the following steps:

[0119] step 1:

[0120] Obtain the vehicle electronic tag position, vehicle position and vehicle image, and conduct electronic non-stop charging transactions:

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

[0122] If there is no on-board electronic tag installed on the vehicle entering the communication are...

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 present invention relates to the field of intelligent transport system (Intelligent Transport System, referred to as: ITS), 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 electronic toll collection (Electronic Toll Collection, abbreviated: ETC) systems for expressways. The existing expressway electronic toll collection system adopts a single-lane mode. Vehicles equipped with on-board electronic tags need to enter the designated lane and pass through the ETC lane at a low speed (the current speed limit of the expressway ETC lane is 20km / h); Vehicles are automatically intercepted by lane railings and processed by manual intervention. [0003] The ETC system uses the ETC antenna and the on-board electronic tag to realize the char...
