Embodiment Construction

[0022] The method for selecting the base site for real-time remote sensing monitoring of motor vehicle exhaust in the urban road network proposed by the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the method proposed by the present invention consists of three layers: the preparation layer, the site selection algorithm layer and the scheme decision layer.

[0024] 1. Preparation layer

[0025] First, determine the area covered by the system, that is, the monitoring range, and then investigate and collect road-related information. Definition The road network is a combination of intersections and roads, expressed as {V, E} in mathematics, where V={v 1 , v 2 ,...,v n} represents the set of intersections, E={e 1 , e 2 ,...,e q} is the collection of roads.

[0026] The roads in the urban road network have many characteristics, such as the width, the number of lanes, whet...

Abstract

The invention discloses an urban road network motor vehicle exhaust real-time remote sensing monitoring base address selecting method is composed of a preparation work layer, an addressing algorithm layer and a scheme decision-making layer. After a monitoring region is determined and relative information is collected, modeling is carried out according to the characteristics of roads, then inherent similarities of an urban road network are searched and classified based on the model, a representative road is selected in each kind, equipment selection is carried out according to road environments, and each scheme is operated individually. Next, each classifying result is assessed, and an optimal scheme is selected. The method is simple in principle and easy to carry out, the calculation amount is modest, and a good effect is obtained.

Description

technical field [0001] The invention relates to a method for selecting a base site for real-time remote sensing monitoring of motor vehicle exhaust in an urban road network, and belongs to the technical field of site selection for public facilities. Background technique [0002] The main pollutants emitted by motor vehicles include CO, CO2, NO, NO2, HC, PM, etc. These pollutants can induce various respiratory and cardiovascular diseases such as asthma, bronchitis, angina pectoris, and coronary heart disease. The 2013 China Motor Vehicle Pollution Prevention and Control Annual Report (hereinafter referred to as the "Annual Report") issued by the Ministry of Environmental Protection shows that in 2012, motor vehicles nationwide emitted 46.121 million tons of pollutants, and automobiles were the main contributor to the total amount of pollutants. NOx and PM exceed 90%, and HC and CO exceed 70%. At the same time, the "Annual Report" pointed out that "yellow label vehicles" which...
