Embodiment 1

[0043] The pole 304 is arranged vertically, and when in use, the pole 304 plays a role of vertical support.

[0044] Two C-shaped locators 307 are arranged at the lower part of the column rod 304, and the two C-shaped locators 307 are arranged one above the other, so

[0045] A groove is provided on the outside of the C-shaped locator 307, and the annular strap 306 can be embedded in the groove and the C-shaped

[0047] The image collector 302 is arranged on the support table, and the image collector 302 is used to map the passing vehicles.

Embodiment 2

[0053] The portal support spans all lanes in the one-way direction of the expressway, and the camera 203 is arranged on the portal support,

[0054] An LED display panel 204 is provided above each lane, and the LED display panel 204 is used to prompt the speed limit;

[0055] Each vehicle detection station 2 is configured with a site manager 201, and the site manager 201 is associated with all the corresponding

[0056] The projection device 205 arranged on the portal support, which points vertically downward, and can project speed bumps and lines

Abstract

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. Select a detection road section for a section of expressway lane with no fork road branch in between, divide the detection road section into a large section and a small section, and set a community detection station at each detection node of the community, and the detection station of the community is fixed. At the guardrail of the community detection node; to obtain the information of the actual vehicle speed and the driving lane of the vehicle at the community detection node, and filter and store the actual vehicle speed information according to the set confidence degree and confidence interval. Factors that have an impact on the speed limit of large intervals include actual vehicle speed, road characteristics of each large interval, natural environment, road congestion in adjacent large intervals, and the number of vehicles entering and leaving high-speed entrances and exits. And restrict the number of vehicles entering the high-speed entrance to achieve the balance of road pressure.

Description

A method for detecting and managing traffic flow between expressways technical field The invention belongs to the technical field of expressway traffic control, and is specifically related to a kind of traffic flow detection between expressway cells and management methods. Background technique Because the speed of different sections of the expressway is not only affected by weather factors such as rain and snow, but also by accidents. Therefore, it is necessary to design a more refined traffic speed detection method to Convenience and management of high-speed traffic flow. SUMMARY OF THE INVENTION [0003] In order to solve the problem in the prior art that the vehicle speed on the expressway cannot be precisely measured and managed Problem, this solution provides a method for detecting and managing traffic flow between expressways. The technical scheme adopted in the present invention is: A kind of traffic flow detection method between expressway cells, compri...
