- •
Dispersion of real vehicle exhaust was measured with a Mobile Lab on a test track.
- •
Results of life-sized CFD modeling using PEMS data were similar to measured trends.
- •
Effect of exhaust plume was decreased as vehicle speed or distance was increased.
- •
The rear height of emitter vehicles ahead was more important than other factors.
- •
Tips were given to avoid unintended exhaust plume during ML air quality surveying.
