Abstract

The invention discloses a dynamic VMS (Variable Message Sign) layout networking method and device, and aims to dynamically display a road network structure and a traffic state and improve a traffic guidance effect. The dynamic VMS layout networking method comprises the following steps: for each VMS display equipment, determining a list of road segments within the guidance range of the VMS display equipment; selecting road segments satisfying a predetermined condition from the list of road segments within the guidance range to form a list of road segments displayed by the VMS display equipment in the present period of time; obtaining the road segment traffic information in the present period of time of the road segments in the list of road segments displayed; determining the corresponding state of each road segment according to the road segment traffic information of each road segment and displaying the state of each road segment on the VMS display equipment; determining whether the guidance effect in the present period of time is superior to that of the last period of time according to the road segment traffic information; if the determination result is negative, returning to the step of selecting road segments satisfying the predetermined condition from the list of road segments within the guidance range to form the list of road segments displayed by the VMS display equipment in the present period of time.

Description

technical field [0001] The invention relates to the technical field of modern traffic control and guidance, in particular to a dynamic networking method and device for a VMS layout. Background technique [0002] In order to alleviate the increasingly serious urban traffic congestion, it is necessary to regulate the travel of motor vehicles, scientifically divert vehicles on congested roads, and reasonably induce travelers to choose the optimal route to spend the least travel time and occupy the least road resources. The existing urban traffic guidance information release and control system is generally based on RTMS, coil detectors, video detectors and other sensor devices to collect traffic flow data in real time. A variety of ways to publish to travelers. At present, the induced information release and control system widely used is the VMS induced information release and control system. The existing urban road VMS information distribution system is generally composed of ...
