Embodiment example

[0089] This evaluation method will construct an evaluation index system for digital infrastructure status, traffic operation status, micro-behavior status, meteorological environment status, etc., so as to conduct evaluation. This paper will take the traffic operation status as an example for case analysis.

[0090] Through the analysis of the existing roadside sensing equipment layout schemes of typical expressways, this paper designs three roadside sensing equipment layout schemes. The selected equipment is all intelligent roadside equipment that can collect traffic operation status data, including high-definition Camera (effective detection area is about 100 meters), millimeter wave radar (effective detection area is about 350 meters), laser radar (effective detection area is about 300 meters).

[0091] The specific plan layout diagram is as follows: image 3 shown. Among them, plan A is to install a set of high-definition cameras every 200 meters, and a set of millimeter...

Abstract

The embodiment of the invention discloses an expressway roadside sensing equipment layout scheme evaluation method and system, and the method comprises the steps: determining a layout scheme evaluation index, and constructing a comprehensive evaluation index system; and based on the comprehensive evaluation index system, evaluating different layout schemes to obtain an optimal roadside sensing equipment layout scheme. Compared with an existing intelligent high-speed design which mainly focuses on historical experience and manufacturer opinions, the method has the advantages that the accuracy of the layout scheme of the highway roadside sensing equipment can be improved, and the roadside sensing equipment can play a huge role under limited configuration, so that the cost performance is relatively high; resource waste is avoided on the basis of meeting traffic perception requirements; in addition, the method can assist intelligent high-speed designers in improving work efficiency, reducing redundant workload, providing scientific data support for intelligent high-speed design and providing basis for compilation of related standard specifications.

Description

technical field [0001] Embodiments of the present invention relate to the technical fields of traffic engineering, smart highways, roadside equipment, and electromechanical design, and in particular to a method and system for evaluating layout schemes of expressway roadside sensing equipment. Background technique [0002] During the design and construction phase of the expressway, designers propose targeted layout plans for sensing equipment such as cameras and millimeter-wave radars that need to be installed on the roadside by considering the characteristics of different roads, traffic, and equipment. At present, in the electromechanical design of smart expressways in my country, there is currently a lack of effective standards and specifications for the layout of roadside sensing equipment, and the few relevant standards can only provide relatively broad guidance, such as "Highway Engineering Adapting to Autonomous Driving Auxiliary Facilities" The General Technical Specifi...
