Multi-factor integration expressway dynamic vehicle speed management and control system

Abstract

The present invention discloses a multi-factor integration expressway dynamic vehicle speed management and control system, belonging to the technical field of expressway traffic safety management andcontrol. The system comprises: an expressway information collection module configured to obtain traffic flow information, meteorological environment information and road structure information of eachsubsection of the expressway and perform preprocessing; an expressway center monitoring module configured to perform comprehensive monitoring of the operation state of each subsection of the expressway and perform overall planning; an expressway speed limitation decision module configured to comprehensively consider various influence factors to decide the speed limitation value of each vehicle model at each subsection of the expressway in real time; an expressway information publishing module configured to dynamically publish the speed limitation information of each subsection and the induction information and warning information of the expressway; and an expressway coordination management and control module configured to perform interconnection and intercommunication with an expressway ramp signal control system and an expressway overspeed capture system to restrict the slip-road flow and timely process overspeed vehicles so as to finally form integrated closed-loop control.

Description

technical field [0001] The invention belongs to the technical field of expressway traffic safety management and control, in particular to a multi-factor integrated expressway dynamic vehicle speed control system. Background technique [0002] As of the end of 2016, the total mileage of expressways in my country reached 130,000 kilometers, ranking first in the world. The mileage has reached 5,000 kilometers, and the road network density ranks first in the country, reaching the level of moderately developed countries. Compared with the development speed of expressway mileage scale, the construction of expressway management and service systems in my country is obviously behind, expressway traffic problems are becoming more and more prominent, and traffic accidents occur frequently, among which speeding and complex meteorological factors are the main reasons for road traffic accidents . Therefore, how to effectively control the expressway speed has become a key concern of expres...
