AB  - The amount of exhaust emissions resulting from the burning of motor vehicles caused the air in the
city of Makassar to be polluted. This study aims to estimate the concentration of Sulfur dioxide (SO<sub>2</sub>) and 
Nitrogen dioxide (NO<sub>2</sub>) for 10 years (2017-2027) on the main road of Makassar city. This research is an 
observational analytic research with dynamic system model approach. Results showed that in the next 10 years,
the estimated total concentration of total Sulfur dioxide (SO<sub>2</sub>) in the first scenario without do nothing in 2017 
of 6.44 &mu;g/Nm<sup>3</sup> increased by 2027 by 8,581 &mu;g/Nm<sup>3</sup> by multiples of increased concentration 61.58 times/month
and an annual increase of 1.80 times/year whereas the estimated concentration of Nitrogen dioxide (NO<sub>2</sub>) in the 
absence of control measures increased from 2017 by 4.99 &mu;g/Nm<sup>3</sup> increased by 2027 by 7,934 &mu;g/Nm<sup>3</sup> by
multiples of increased concentration 37.6 times/month. Application of Second Scenario (2) has decreased total
concentration of Sulfur dioxide (SO<sub>2</sub>) and Nitrogen dioxide (NO<sub>2</sub>) when compared to total concentration in first 
scenario (I). Increasing the concentration of Sulfur dioxide (SO<sub>2</sub>) in 2017 by 6.44 &mu;g/Nm increased by 2027 by 

3785 &mu;g/Nm<sup>3</sup> with total monthly concentration increase of 37.4 times/months and total annual concentration
increase of 0.72 times/year. Effectiveness in the second scenario in reducing the concentration of Nitrogen
dioxide (NO<sub>2</sub>) by 22.72%. Application of the third scenario (3) there is a significant decrease in the concentration 
of sulfur dioxide and nitrogen dioxide when compared to the first scenario (1). Effectiveness in the third scenario
(3) in reducing sulfur dioxide concentration of 66.43%. Implementation of the fourth scenario (4) passenger shift
for the use of bus rapid transportation (bus rapid transportation) with the aim of decreasing the volume of
vehicles operating on the main road, if it is assumed that 50% of passengers switch to BRT bus, BRT
passengers in 2027 will be 3960/days.
