Embodiment Construction

[0027] In order to realize the dynamic display of the road network structure and traffic status and improve the traffic guidance effect, the embodiments of the present invention provide a dynamic networking method and device for a VMS layout.

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings of the specification. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention, and in the case of no conflict, the present invention The embodiments in and the features in the embodiments can be combined with each other.

[0029] In the embodiment of the present invention, the urban road network is described by establishing a node-arc model, and the attribute of the road segment is expressed by the weight of the arc, and its formal expression is:

[0030] G = ( V , E , W ) V =...

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 method and device for dynamic networking of 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 sections, and reasonably induce travelers to choose the optimal route to spend the least travel time and occupy the least road resources. Existing urban traffic guidance information release and control systems are generally based on RTMS, coil detectors, video detectors and other sensor devices that collect traffic flow data in real time. These data are processed and analyzed by the control center, and then text, graphics, voice, etc. This way is released to travelers. The currently widely used guidance information release and control system is the VMS guidance information release and control sys...
