Real -time traffic information monitoring and QOS grading control system and method

Abstract

The invention discloses an all-weather real-time traffic information monitoring and QoS grading control system and method. The system includes a data acquisition, aggregation and control subsystem, a data decomposition and combination subsystem, an intelligent data analysis subsystem and an intelligent QoS grading subsystem. The data acquisition, aggregation and control subsystem is used to isomerize the various systems at the intelligent roadside, and integrate and aggregate the data of these systems; the data decomposition and combination subsystem is used to associate the integrated and aggregated data with road physical elements, and extract the associated elements. ;Intelligent data analysis subsystem is used for artificial intelligence to analyze related elements and determine the system parameters that need to be controlled; intelligent QOS classification subsystem is used to analyze the adaptive QOS level of current road conditions, and determine the system that needs to be adjusted to improve road service quality The parameters and traffic guidance information are finally returned to the data acquisition, aggregation and control subsystems. The invention can realize all-weather real-time monitoring of road traffic information.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic 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 system 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 infrastructure through roadside communication systems, vehicle-road information interaction rules, etc. Specifically, the roadside system sends high-precision geographic information, positioning assistance information, traffic rule information, traffic environment information, infrastructure information, r...

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
