Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] Such as figure 1 As shown, the present invention provides a highway multi-path identification and traffic state estimation system based on 5.8GHz dedicated short-range communication technology. The charging system includes route information initialization module I, multi-source data access module II, multi-source data fusion module III, toll splitting module IV and state information sharing module V.

[0047] Its specific application method includes the following steps:

[0048] 1) path information initialization module 1 clears the path information at the entrance lane system, and the RSU read-write device reads out the vehicle information in the vehicle-mounted device, and writes information such as entrance time, entrance toll station numbering in the ETC-IC card, and the lane will be The entrance vehicle information is transmitted to the data center in rea...

Abstract

The invention discloses a multipath recognition and traffic state estimation system for a highway, and the system comprises a path information initialization module, a multi-source data access module,a multi-source data fusion module, a toll splitting module, and a state information sharing module. The system makes the most of a path recognition system to iron out the defect that the arrangementof fixed detectors is not sufficient, enables a traffic state estimation result of the highway to be more accurate and the coverage to be larger, improves the operation monitoring of a highway network, facilitates the timely finding of a traffic jam, and guarantees the safety and passing efficiency of the highway.

Description

technical field [0001] The invention belongs to the field of expressway multi-path identification and fusion traffic state estimation, in particular to a method and system for ambiguous path identification charging and traffic state estimation based on 5.8GHz dedicated short-range communication technology. Background technique [0002] When vehicles are driving on the same highway network, there are multiple driving paths between the exit and the entrance, which involve different toll calculation methods and toll splits. The problem of ambiguous paths brings two problems to the expressway network toll collection: on the one hand, how to confirm the user's driving route to calculate the toll amount; on the other hand, how to split the expressway toll among owners. Most domestic expressways adopt semi-automatic toll collection (MTC) system and electronic non-stop toll collection (ETC) system using IC card as the toll medium. These two toll collection systems do not have the fu...
