2004 journal article

Quantification of highway vehicle emissions hot spots based upon on-board measurements

JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION, 54(2), 130–140.

By: A. Unal n, H. Frey  n & N. Rouphail n 

MeSH headings : Air Pollutants / analysis; Data Collection; Environmental Monitoring / methods; Models, Theoretical; Vehicle Emissions / analysis
TL;DR: Average speed, average acceleration, standard deviation of speed, percent of time spent in cruise mode, minimum speed, maximum acceleration, and maximum power have statistically significant associations with vehicle emissions and influence emissions hot spots. (via Semantic Scholar)
