AT A GLANCE
Joined Air Quality Index (AQI) and transportation statistics for Maryland covering 2023–2024. Supports research at the intersection of environmental health and transportation policy.
Key Highlights:
- Coverage: State of Maryland, 2023–2024
- Content: Four linked tables — AQI + transportation for both years
- Focus: Relationship between transportation activity and air quality
- Variables: AQI measurements, transportation metrics, temporal indicators
PROJECT DESCRIPTION
This dataset enables analysis of how transportation infrastructure and traffic patterns relate to air quality outcomes. Researchers can examine year-over-year trends from 2023 to 2024, investigate correlations between transportation activity and AQI values, and evaluate the effectiveness of transportation policies on air quality improvement.
Research Applications:
- Transportation-air quality correlation analysis
- Year-over-year trend comparison (2023 vs. 2024)
- Environmental policy impact assessment
- Spatial analysis of pollution and traffic patterns in Maryland
Subject Terms: air quality, transportation, Maryland, environmental health, traffic, public health, policy analysis
SCOPE & METHODOLOGY
- Geographic Coverage: Maryland, United States
- Smallest Geographic Unit: State / county / traffic zone
- Time Period: 2023 – 2024
- Universe: Air quality monitoring stations and transportation infrastructure in Maryland
- Unit of Observation: State-level / zone-level aggregate (annual)
- Data Type: Administrative records — environmental and transportation monitoring data
Data Collection: AQI measurements and transportation statistics for Maryland joined across four tables covering both 2023 and 2024 data. Hosted on the BSOS Data Repository platform.
