Embodiment 1

[0041] Such as figure 2 As shown, the present embodiment designs a community detection station 3. The community detection station 3 includes an image collector 302, a vehicle speed detector 303, a community controller 305, a mast 304, a ring strap 306 and a C-shaped locator 307 and other structures. The sub-district detection station 3 can be installed on the guardrail on the edge of the expressway at the road section between the sub-districts, so that it can facilitate the rapid detection of the lane on which the vehicle is traveling and the speed of the vehicle, thus realizing The lane information and speed information of the vehicle are quickly sampled.

[0042] Guardrails are often arranged on the edge of the expressway, and the guardrails include piles; the community detection station 3 can not only facilitate the unification of the installation height of the community detection station 3 through the piles fixed to the guardrail, but also can borrow existing There is a...

Embodiment 2

[0051] Such as image 3 As shown, a vehicle detection station 2 is designed in this embodiment. The vehicle detection station 2 is set at the starting point of each large-interval road section, and communicates with the community detection stations 3 of all small-district road sections in the large-interval road section. . To obtain the actual vehicle speed and the information of the driving lane of the vehicle in the detection node of the cell, and filter and store the actual vehicle speed information according to the set confidence degree and confidence interval.

[0052] The vehicle inspection station 2 includes structures such as a door frame, a camera 203 , an LED display board 204 , a site manager 201 , and a projection device 205 . Site manager 201 can be existing equipment such as computer, server or industrial computer, and it mainly realizes functions such as receiving, storing and forwarding the data of camera 203, and realizes the display control of LED display pa...

Embodiment 3

[0058] Such as Figure 1 to Figure 4 As shown, utilizing the structure of embodiment 1 and embodiment 2, the present embodiment has designed a kind of traffic flow detection method between expressway sub-districts, and this traffic detection method comprises the following steps:

[0059] Step A1: Select a detection road section for a section of expressway lane with no fork road branch in between, and divide the detection road section into a plurality of continuous large interval road sections according to the road characteristics, and the end point of each large interval road section is used as the next large interval road section starting point;

[0060] Step A2: Divide each large inter-district road segment into multiple consecutive sub-district road segments at equal distances; the end point of each sub-district road segment is used as the starting point of the next sub-district road segment; the starting position of each sub-district road segment is selected as the cell de...

Abstract

The invention belongs to the technical field of expressway traffic control, and particularly relates to an expressway inter-cell traffic flow detection and management method. The method comprises the following steps of: selecting a detection road section for a section of expressway lane without a branch, dividing the detection road section into a large-section road section and a small-section road section, arranging a community detection station at each community detection node, and fixing the community detection station at a guardrail of the community detection node; the actual vehicle speed of the vehicle at the community detection node and the information of the driving lane are obtained, and the actual vehicle speed information is screened and stored according to the set confidence coefficient and confidence interval. Factors influencing the speed limit of large-interval road sections, including actual vehicle speed, road characteristics of each large-interval road section, natural environment, road congestion conditions of adjacent large-interval road sections, the number of vehicles entering and exiting from a highway entrance and a highway exit, and the like, are used for reference, and the number of vehicles entering from the highway entrance is restrained. And the balance of road pressure is realized.

Description

technical field [0001] The invention belongs to the technical field of expressway traffic control, and in particular relates to a method for detecting and managing traffic flow between expressway sub-districts. Background technique [0002] Because the speed of different road sections of the expressway is not only affected by weather factors such as rain and snow, but also affected by accidents, holidays, and road section characteristics, it is necessary to design a more sophisticated traffic speed detection method to facilitate the detection of high-speed traffic. to manage. Contents of the invention [0003] In order to solve the problem that the vehicle speed on the expressway cannot be accurately measured and managed in the prior art, this solution provides a method for detecting and managing traffic flow between expressway communities. [0004] The technical scheme adopted in the present invention is: [0005] A method for detecting traffic flow between expressway s...
