Text description of figure
Figure A1-1 shows a comparison of the normalised dispersion curves for predicted concentrations of carbon monoxide at increasing distance from the road under three different approaches; one based on the parameters recommended by Austroads and two based on the methods discussed above. The Austroads curve predicts significantly lower concentrations (approximately half) than the Scoggins et al curve within 50 m of the roadside.
