CARBON MONOXIDE DISTRIBUTION AROUND CAIRO-ALEXANDRIA HIGHWAY

Simultaneous measurements of carbon monoxide were conducted on both sides of the major traffic road in Egypt. These values were used to test and validate the highway line source model against a real air quality set of data. A non-zero value was assumed to account for the initial dispersion that occurs due to the turbulence wake behind moving vehicles. The model initially was found to overestimate carbon monoxide concentrations detected around the highway. However, the consideration of each lane as an individual source resulted in reasonable agreement between measured and predicted concentrations with a correlation coefficient of more than 0.8.
