Embodiment Construction

[0047] Such as figure 1 Shown is a kind of intelligent induction method based on the floating car on the ramp of the expressway, the method includes the steps in the following order:

[0048]S1. Set up the guidance screen equipment in front of the ramp of the expressway, divide the section of the expressway into code Pi, and code z of the ramp of the expressway h code with the guidance screen equipment, and associate and pair the section division code Pi, expressway ramp code z and the guidance screen equipment code. Use formula (0) to code z for the expressway ramp h Perform one-to-many association pairing with the section code Pi,

[0049] z h ={P 1 ,P 2 ,...,P i} (i∈I, h∈H) (0)

[0050] Among them, I represents the total number of all sections on the expressway; H represents the total number of all ramps on the expressway.

[0051] S2. The real-time dynamic parameter data acquired by all the floating vehicles in the road network detected by the floating vehicle is t...

Abstract

The invention relates to an express way ramp intelligent inducing method and device based on floating vehicles. The method comprises the following sequential steps that inducting screen devices are arranged in front of express way ramps, and way segment partitioning and coding, ramp coding and inducing screen device coding are conducted; real-time dynamic parameter data of all the floating vehicles in a floating vehicle detection way network are obtained and transmitted to a background server to conduct standardized storage; the average travel time and the average travel speed of all the floating vehicles on all way segments of a way are calculated; the way segment average travel time is corrected, the real-time traffic operation indexes of all the way segments of the express way are obtained; the average traffic operation index of all the ramps is calculated, and the traffic operation state levels of related way segments of all the ramps are determined; an intelligent traffic inducing model is established, and intelligent traffic inducing strategies are displayed in real time through the inducing screen devices. By means of the express way ramp intelligent inducing method and device, express way ramp intelligent traffic inducing can be achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic guidance of urban expressways and elevated ramps, in particular to an intelligent guidance method and device for expressway ramps based on floating vehicles. Background technique [0002] With the sharp increase in urban car ownership, the contradiction between traffic flow and road supply and demand has become increasingly prominent. The emergence of urban expressways has greatly increased the choice of travel routes, but expressways have brought smooth travel and brought more contradictions. During peak hours, the expressway becomes a parking lot, which greatly delays the travel of the public. [0003] Intelligent traffic guidance is an effective way to solve expressway congestion. The traditional method is mostly to adjust the traffic flow of the elevated road by manually closing the ramp, which delays emergency treatment and wastes labor costs; through intelligent traffic informati...
