Evaluation of roadway pollutant dispersion models using mass flux profiles and mass conservation

Four roadway models used to predict emission dispersion were assessed by using mass conservation checks and mass flux profiles. Several models were deemed inaccurate because they did not take changes in wind speed into account. They were also found to give a false representation of transport process...

Zusammenfassung:Four roadway models used to predict emission dispersion were assessed by using mass conservation checks and mass flux profiles. Several models were deemed inaccurate because they did not take changes in wind speed into account. They were also found to give a false representation of transport processes at angles other than 90 .
