From: Prediction and analysis of near-road concentrations using a reduced-form emission/dispersion model
Comparison of CALINE model predictions (shown as solid lines) and reduced model predictions (shown as points) showing effects of A) wind angle; B) wind speed; and C) traffic volume for four distances (30, 60, 120, 240 m) from the road. All plots use nominal conditions (wind speed = 4 m s-1, VPH = 10,000; emission rate = 300 g mi-1; wind angle = 180°). Panel D plots concentrations from the two models for all conditions showing 1:1 line and 15% error intervals.
