Scope

This document specifies the monitoring items, monitoring conditions, monitoring methods, monitoring systems, quality control, monitoring data recording and processing, and monitoring results reporting for air pollutants and greenhouse gas emissions from motor vehicles on highways. The formulation of this standard is conducive to controlling air pollutants and greenhouse gas emissions from highway motor vehicles. The development of this standard provides a technical and data foundation for future air pollutant emission management and remote monitoring by both traffic departments and environmental protection departments, and promotes the establishment of air pollutant emission supervision models and the optimization of management methods for highway motor vehicles. Based on actual measurements of motor vehicle emissions, this standard selects monitoring items for characteristic pollutants and greenhouse gases from motor vehicles. At the same time, according to the characteristics of highway traffic and geographical environmental features, typical sections for monitoring are selected. The monitoring cycle refers to relevant environmental standards. On the basis of existing monitoring methods for various monitoring factors, the infrared open optical path method is added and verified by actual measurement. The proposed standard applies flexible site selection to high-flow sections of highways, entrances and exits of extra-long tunnels, and congested sections, etc. of complex highway conditions. In addition to traditional point-based monitoring methods, the standard also adds infrared open optical path monitoring methods, which apply to the characteristics of highway linear projects and support real-time detection of 50-500m long optical paths. The working conditions of the standard equipment, including a wide range of temperature and humidity, increase its adaptability to the environment. The standard requires data to be shared online and is highly adaptable to seamless
