Abstract
According to Decree of Semarang Mayor No. 22/2011, car free day activities is addressed to give clean air for facilitating citizens activities. This car free day event is held every Sunday in the morning in the city center of Semarang i.e. located at Simpang Lima square. This research is aimed at identifying the shifting of pollutant during car fee day event by comparing ambient air pollutant concentration represented by carbon monoxide during car free day event and non-car free day event. About 14 streets had been measured its ambient CO concentration during Saturday (non-car free day event) and Sunday (car free day event). We also modeled (using Caline4) the CO dispersion at the certain area on those streets to know the spatial distribution of concentration during those two events. The ambient CO concentration, in general, during car free day event were somewhat increase for certain roads. The emission load of vehicles emission during CFD event was 1.37 times of non-CFD event. Nevertheless, based on spatial distribution of ambient CO concentration at the area of roads of interest, its concentrations were below the ambient CO concentration standard (PP.41/99).

Summary
As the city becoming bigger due to urbanization, transportation matter is important part of city growth. Uncontrolled growth of vehicles owned privately in one side and limited growth of road inner the city in other side make unbalanced growth and further it makes congestion and traffic jam. Based on this issue, it is indispensable for many cities to eagerly try to reduce the private vehicles use in city centers. Cities from around the world seem to become more willing to try car free initiatives [1] in developed countries. These initiatives supported by city government should be participated by the citizen to run it effectively. The measures on reduction of motorized traffic is deemed to give benefit to public health, both in the short and long-term [2]
