Traffic-related environmental impacts of fracking studied using a novel Traffic Impact Model.
Model estimates greenhouse gas, local air quality, noise and axle loading impacts on roads.
Single well pad creates substantial increases in local air quality pollutants during peak activity.
Short-duration/large-magnitude events may adversely affect local ambient air quality and noise.
Daily NOx emissions may increase by over 30% and hourly noise levels can double (+ 3.4 dBA)
