Abstract
Intersections are mainly considered as critical elements of road networks in terms of air quality impact, and their control type and geometric configuration can affect significantly vehicular emissions. This study aims mainly to investigate the effect of traffic flow on the level of pollution at a selected intersection in Kerbela city. Hence, the video camera has been installed for three normal days to investigate the traffic flow fluctuation for 24h. Then, Gasmet has been used for investigating the amount of emission for both CO2 and CO within the peak hour. A well-known SIDRA 8.0 has been used for analyzing the intersection. The results indicated that the CO2 is exceeded the acceptable limit with worse traffic operations for both selected intersections.
