All-weather real-time traffic information monitoring and QOS hierarchical control system and method

Abstract

The invention discloses an all-weather real-time traffic information monitoring and QOS hierarchical control system and method. The system comprises a data acquisition convergence and control subsystem, a data decomposition combination subsystem, an intelligent data analysis subsystem and an intelligent QOS grading subsystem. The data acquisition, convergence and control subsystem is used for carrying out isomerism on each system of the intelligent roadside end and integrating and converging the data of the systems; the data decomposition and combination subsystem is used for carrying out road physical element association on the integrated and converged data and extracting associated elements; the intelligent data analysis subsystem is used for carrying out artificial intelligence analysis on the associated elements and determining system parameters needing to be controlled; and the intelligent QOS grading subsystem is used for analyzing the QOS grade which can be adapted to the current road condition, determining system parameters and traffic guidance information which need to be adjusted for improving the road service quality, and finally returning the system parameters and the traffic guidance information to the data acquisition convergence and control subsystem. According to the invention, all-weather real-time monitoring of road traffic information can be realized.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation and vehicle-road information interaction, in particular to an all-weather real-time traffic information monitoring and QOS hierarchical control system and method. Background technique [0002] Intelligent transportation is a transportation-oriented service system based on modern electronic information technology. Its construction focuses on intelligent roadside systems based on road traffic information, road perception, and vehicle coordination. The information interaction between traffic participants and roadside infrastructure connects people, vehicles and intelligent transportation foundations through roadside communication systems and vehicle-road information interaction rules. Specifically, the roadside system sends high-precision geographic information, positioning assistance information, traffic rule information, traffic environment information, infrastructure information...

AI Technical Summary

Problems solved by technology

However, there are some problems in the existing intelligent traffic monitoring and control of the road, mainly including that the systems of the intelligent roadside end are separated, and different systems complete their own determined tasks, resulting in the formation of their own data systems, which is difficult Form an overall judgment on the condition of the road

In addition, the data of each system is not well correlated and managed, it is difficult to control the quality of on-site and all-weather road services, and it is impossible to maximize the effectiveness of infrastructure
