Ⅰ. Background and Aims of Research
1. Background and aims of research
oIt is import to build the database for the development of local environmental policy in terms of the “integrated management” perspective across various fields.
ㅇThis study focuses on building and analyzing basic data for improving reliability of the air pollutant emission information system, understanding the national distribution of vulnerable population exposed to high levels of PM2.5 concentration from the health science perspective, setting a policy inventory for comprehensive environmental policy management, and cooperation/governance development for policy implementation.

2. Key contents of surveys and data
oThis study includes the awareness surveys and data to support local environmental policies for PM mitigation as follows.
ㅇBuilding data on the traffic of three types of road construction equipment
ㅇBuilding data on the vulnerable populations exposed to the high level of PM2.5 concentration
ㅇBuilding data on the PM mitigation policy inventory
ㅇAwareness survey of local government officials for PM mitigation
Ⅱ.Building Data on the Traffic of Three Types of Road Construction Equipment
1. Overview of building data
oThe primary purpose of building data is to identify the traffic characteristics of the three different types of road construction equipment, based on which the adequacy of the basic data used to estimate CAPSS emissions is to be determined.
ㅇThe Ministry of Land, Infrastructure, and Transport is allowed to use the Computer Information Processing Organization to ensure the efficient mana
