Abstract
The in-use diesel trucks have high use intensity, high mobility, and frequent excessive emissions, which have become one of the important air pollution sources. The Action Plan for Tackling the Challenges of Diesel Truck Pollution Control issued by the Chinese government requires the establishment of a national monitoring network for transport-related air pollution and the use of various means to monitor diesel truck emissions. This study briefly summarized the requirements for diesel truck emission monitoring and supervision. Relying on the highway network traffic survey data, a method for identifying the main route of regional highway freight transportation was proposed. Then referring to the experience of highway air quality monitoring networks at home and abroad, the article proposed layout methods for roadside air quality monitoring stations, vehicle remote sensing monitoring stations, and road inspection stations, which fills the gap in domestic methods. At last, a demonstration study on the layout plan for the in-use diesel truck emissions monitoring stations in Shanxi Province was carried out. Taking Shanxi’s main highway freight corridors as the key supervision area, this article screened out 44 roadside air quality monitoring stations, 24 vehicle remote sensing monitoring stations, and 15 road inspection stations.
Highlights
According to the China Mobile Source Environmental Management Annual Report (2019) issued by the Ministry of Ecology and Environment of China, diesel trucks that accounted for 7.9% of vehicle ownership in the whole country emitted 60.0% of nitrogen oxides (NOx) and 84.6% Particulate matter (PM) of total vehicle emissions in 2018, which are the top priority of motor vehicle pollution prevention
At the end of 2018, the Chinese government issued documents such as the Action Plan for Tackling the Challenges of Diesel Truck Pollution Control, which clearly required the establishment of a national monitoring network for transport-related air pollution and comprehensive monitoring and supervision of diesel trucks emissions by various means
In order to better support the construction of transport-related air pollution monitoring network and diesel truck emissions supervision, this study intends to focus on the identification method of highway freight corridors and the layout method of diesel truck emissions monitoring and supervision stations based on highway traffic survey data
Summary
According to the China Mobile Source Environmental Management Annual Report (2019) issued by the Ministry of Ecology and Environment of China, diesel trucks that accounted for 7.9% of vehicle ownership in the whole country emitted 60.0% of nitrogen oxides (NOx) and 84.6% Particulate matter (PM) of total vehicle emissions in 2018, which are the top priority of motor vehicle pollution prevention. Diesel trucks are mainly commercial vehicles, with high intensity of use, harsh operating environment, and relatively high pollution emissions. They have become an important pollution source affecting the atmospheric environmental quality of many cities, and have gradually attracted widespread attention from the government and the public. In order to better support the construction of transport-related air pollution monitoring network and diesel truck emissions supervision, this study intends to focus on the identification method of highway freight corridors and the layout method of diesel truck emissions monitoring and supervision stations based on highway traffic survey data
