Path fitting algorithm

Abstract

The invention discloses a path fitting algorithm, which comprises the following steps of: preprocessing data; and performing path fitting calculation on the processed transaction data. The method is suitable for the technical field of high-speed path fitting, incomplete charging records are complemented through path fitting, income loss of high-speed enterprises caused by missing collection is avoided, the charging calculation capability and calculation accuracy of high-speed charging are improved, and the charging efficiency is improved; according to the method, historical fitting paths are counted and archived, ETC portal equipment faults and suspicious vehicles are identified and early warned, the ETC portal equipment faults are checked and positioned, the suspicious vehicles are checked, and behaviors of deliberate card pulling and calculation omission are positioned and distinguished; and by restoring the complete passing path, the flow rule on the expressway can be analyzed, data support is provided for further inducing traffic flow, improving operation efficiency, reasonably arranging maintenance tasks and the like, and the operation efficiency of the expressway and the accuracy and economic benefits of maintenance operation are improved.

Description

technical field [0001] The invention belongs to the technical field of high-speed path fitting, in particular to a path fitting algorithm. 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 efficiency. At the same time, the existing technology Unable to troubleshoot abnormal records, unable t...

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 rule out 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 traffic flow law on the highway leads to low operating efficiency of the highway, poor accuracy and economic benefits of maintenance operations
