Road traffic management decision support device

Abstract

The invention discloses a road traffic management decision support device. The device comprises a plurality of acquisition units, an analysis and decision unit and a road control unit, wherein, the acquisition units are arranged on different roads and are used for acquiring vehicle running information of the roads; the analysis and decision unit calculates and makes the road decisions according to the vehicle running information of the roads acquired by the acquisition units; the road control unit controls the vehicle running condition of the roads according to the road decisions made by the analysis and decision unit; and the acquisition units, the analysis and decision unit and the road control unit are sequentially and electrically connected together. The road traffic management decision support device provided by the invention has the beneficial effects of analyzing traffic stream status on the basis of monitoring the road running state in real time so as to find out a potential traffic incident and start an emergency plan immediately, and reasonably inducing the traffic stream on a highway to keep away from each other through ramps and other routes, thus minimizing accidents, reducing vehicle delay and improving running efficiency.

Description

technical field [0001] The invention relates to a road traffic management decision support device, in particular to a road traffic management decision support device suitable for expressways. Background technique [0002] With the optimization of road construction and control, especially the operation of the current expressway has greatly shortened the transportation time and improved the transportation efficiency, but at the same time, there have been many problems in the management of the expressway, such as traffic congestion and traffic accidents, etc. The problem is becoming more and more serious. Therefore, how to effectively manage and control the vehicle operation of the expressway, so as to make it more intelligent, informatized and modernized has always been the focus and hot spot of research in the field of traffic engineering at home and abroad. [0003] The current management and control of vehicle operation on expressways is limited to traffic nodes that are pr...

Problems solved by technology

[0002] With the optimization of road construction and control, especially the operation of the current expressway has greatly shortened the transportation time and improved the transportation efficiency, but at the same time, there have been many problems in the management of the expressway, such as traffic congestion and traffic accidents, etc. The problem is becoming more and more serious. Therefore, how to effectively manage and control the vehicle operation of the expressway, so as to make it more intelligent, informatized and modernized has always been the focus and hotspot of research in the field of traffic engineering at home and abroad.

[0003] The current management and control of vehicle operation on expressways is limited to traffic nodes prone to traffic jams and traffic accidents, and cannot effectively use the traffic network to dynamically distribute traffic flow. In addition, if there is a traffic emergency, due to lack of Efficient traffic network allocation methods, which cannot respond to traffic emergencies in real time
