Highway toll collection method and system for ETC multi-sensor information fusion track restoration

Abstract

The invention belongs to the technical field of intelligent transportation, and provides a highway toll collection method and system for ETC multi-sensor information fusion track restoration. The highway toll collection method for ETC multi-sensor information fusion trajectory restoration comprises the steps: acquiring vehicle-mounted positioning breakpoint information, restoring a vehicle drivingpath, and calculating the estimated cost of high-speed driving of a vehicle, wherein the vehicle-mounted positioning breakpoint information is a discontinuously acquired positioning signal, and the positioning signal is acquired every time when the intensity of the communication base station signal reaches the highest and begins to weaken; comparing the estimated fee with the ETC fee deduction amount of the expressway exit; when the difference between the estimated fee and the ETC fee deduction amount of the expressway exit exceeds a preset amount threshold value, continuing to compare the restored vehicle driving path with the ETC portal frame segmented fee deduction driving path, and determining whether to release traffic and judging whether there is a fee evasion problem or not according to the consistency of the paths.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a high-speed charging method and system for ETC multi-sensing information fusion trajectory restoration. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the continuous development of the economy and the increasing number of vehicles, manual toll collection can no longer meet the needs of high-speed toll roads, and the traffic capacity of ETC (Electronic Toll Collection, electronic non-stop toll collection system) toll channels can reach 5 to 10 times that of manual toll channels. times, and with the strengthening of scientific research and technology and the increasingly severe traffic conditions, ETC will replace manual toll collection. ETC is a road-side unit (Road-Side Unit, RSU for short) and vehicle-moun...

Problems solved by technology

[0004] At present, there are the following problems in the status quo of ETC system fee evasion: First: "run long and buy short", that is, some vehicles use false documents to cheat OBU, illegally disassemble OBU, etc., and change the OBU into "handheld" for switching use, for example : One car applies for the installation of OBU in two places or two provinces, and the entrances are all marked, but one of the access cards has no exit flow, so that the card is changed on the way to achieve the purpose of "running long and buying short". This method is extremely concealed

[0006] The above schemes are to use video recognition and sensing technology to identify vehicles and use mobile base stations to record driving paths. The inventors have found the following problems: First, the existing toll collection systems need to install various equipment at ETC entrances and exits and lane gantry frames , increasing the initial investment and later equipment maintenance costs, the overall investment is huge, and the preparation period is long; second: only from a single image or sensing technology to identify and verify vehicle information is less accurate and less efficient; third : The mobile base stations are widely distributed, and the mobile base station information of other paths will be obtained in one path, resulting in the inability to accurately restore the path of the vehicle when the background processing of the mobile base station information restores the path
