Atlanta Fleet Evaluation

Emissions of air pollutants by mobile sources are responsible for more than 60% of total air pollution. One of the main sources is vehicle exhaust emissions. Researchers analyze vehicle emissions using remote sensing technology. Researchers are responsible for conducting the Continuous Atlanta Fleet Evaluation (CAFÉ) program for the Georgia Department of Natural Resources. CAFÉ is the longest-running remote sensing program in the world. Collected emissions data is evaluated biannually to assess the effectiveness of Atlanta’s Inspection and Maintenance program.

Validation & Vision: Long-Term Emissions Monitoring Validates Vehicle Inspection Program and Offers Policy Insights

Atlanta Fleet Evaluation

The numbers tell the story: 25 Georgia counties, about 420,000 vehicles assessed for emissions each year at more than 60 monitoring sites, data gathered for at least 100 days a year in the field. Fifteen years of systematic data collection along the roadside, now with a fourth generation of equipment. Georgia Tech researchers use remote sensing equipment to monitor emissions from vehicles in the metropolitan Atlanta area. Their long-term work has validated the effectiveness of emissions control strategies.
