Expressway congestion management and control system based on multi-source data

Abstract

The invention discloses an expressway congestion management and control system based on multi-source data, and the system comprises an intelligent perception subsystem, a data management subsystem, a congestion prediction and early warning subsystem, an online simulation subsystem, and a visual application subsystem. The intelligent perception subsystem is connected with the data management subsystem, the data management subsystem is connected with the congestion prediction and early warning subsystem, the congestion prediction and early warning subsystem is connected with the online simulation subsystem and the visual application subsystem;the online simulation subsystem and the visual application subsystem are connected with each other; the intelligent perception subsystem provides basic traffic data support, the data management subsystem processes and stores basic traffic data, the congestion prediction and early warning subsystem performs traffic state evaluation, and the online simulation subsystem performs simulation testing to find an optimal management and control scheme suitable for a current traffic flow state; and the visual application subsystem is used for effect presentation and information release.

Description

technical field [0001] The invention relates to the field of traffic management, in particular to a highway congestion control system based on multi-source data. [0002] technical background [0003] The expressway congestion control system is considered to be an effective means to promote the operation capacity of the expressway road network. However, the implementation efficiency of the management decision-making system under the condition of expressway congestion in my country is not high. Fully collect and utilize multi-source traffic big data to comprehensively analyze traffic operation conditions to achieve information sharing; the expansion of advanced technology is relatively lacking, and the existing expressway congestion control technology is relatively backward, unable to analyze and predict traffic situations in a wider space-time range , to build a refined and intelligent expressway congestion management system; the output of the congestion control implementation ...

[0003] The expressway congestion control system is considered to be an effective means to promote the operation capacity of the expressway road network. However, the implementation efficiency of the management decision-making system under the condition of expressway congestion in my country is not high. Fully collect and utilize multi-source traffic big data to comprehensively analyze traffic operation conditions to achieve information sharing; the expansion of advanced technology is relatively lacking, and the existing expressway congestion control technology is relatively backward, unable to analyze and predict traffic situations in a wider space-time range , build a refined and intelligent expressway congestion management system; the output result of the congestion control implementation plan is relatively single, and the comprehensive integration degree is low, so it is impossible to generate and compare the pros and cons of multiple sets of congestion evacuation plans to achieve the purpose of optimal implementation
