Path fitting method and device for expressway transaction

Abstract

The invention discloses a path fitting method and device for expressway transactions. The method comprises the steps of taking an entrance toll station, an ETC door frame and an exit toll station carried in expressway transaction data corresponding to an expressway transaction as passing points and sequentially sorting according to transaction time; verifying the expressway transaction data based on a predetermined business rule; querying each passing point in the expressway transaction data according to the sorting of the passing points, and calculating whether a shortest path exists between the currently queried passing point and the passing points which are separated by a set step length and are not directly communicated based on a pre-established expressway network topology directed graph model so as to determine whether the current passing point is an abnormal passing point, determining a missed charging point and a wrong charging point, and carrying out path fitting based on the missed charging point and the wrong charging point determination result; and the weight of the edge in the directed graph being the cost corresponding to the ETC portal frame pointed by the edge. Incomplete charging records are complemented, and the income loss of high-speed enterprises caused by missing collection is avoided.

Description

technical field [0001] The invention belongs to the technical field of transportation, more specifically relates to the technical field of high-speed path fitting, and in particular to a path fitting method and device for expressway trading. Background technique [0002] From 0:00 on January 1, 2020, the national expressway networked toll system has completed the grid-connected switch, all 487 expressway toll stations at provincial boundaries have been cancelled, and expressways have changed from closed toll collection to open section free-flow toll collection. The new charging mode is realized by erecting an ETC gantry with an on-board unit that can automatically deduct fees on the high-speed toll road section; [0003] However, the current ETC traffic transactions have errors, omissions, etc., which have caused serious losses to high-speed companies, resulting in poor charging calculation capabilities and low calculation accuracy for high-speed billing, and poor charging e...

Problems solved by technology

[0003] However, the current ETC traffic transactions have errors, omissions, etc., which have caused serious losses to high-speed companies, resulting in poor charging calculation capabilities and low calculation accuracy for high-speed billing, and poor charging efficiency. At the same time, the existing technology Unable to troubleshoot abnormal records, unable to exclude interference data existing in transactions, difficult to identify wrongly received masts, resulting in difficulty in troubleshooting ETC masts, difficult to troubleshoot and give early warning of suspicious vehicles maliciously evading fees, and existing technologies are difficult to detect high-speed Analysis of the flow law on the highway leads to low operating efficiency of the highway, poor accuracy and economic benefits of maintenance operations
