Transportation problems in the form of congestion, delays, as well as air and noise pollution are very common in several big cities in Indonesia such as Denpasar City (the capital of Bali Province). Traffic congestion has been experienced on almost all major roads in Denpasar City and one of them is Sudirman road. There are several signalized intersections located at close distances. Traffic jam is usually experienced during peak hour which causes an increase in travel time, energy consumption, and air pollution. There is a potential to coordinate these intersections in order to reduce congestion. The objective of this study is to optimize intersection performances by coordinating traffic signals. This study applied a micro-simulation approach by using Vissim software. The t-test method was used to test the validity of the simulation. The results indicated that the intersections were in the level of service F. Comparison of the intersection performances showed that there was an increase in the intersection performances as indicated by the decrease in the queue length, delay, stop delay, and fuel usage. There was a decrease in the queue length of about - 18.52% (from 544.63 m to 443.74 m), a decrease in the delay of about - 20.41% (from 344.19 sec/pcu to 273.94 sec/pcu), a decrease in the stop delays of about -21.61% (from 32.84 sec/pcu to 25.74 sec/pcu) and a decrease in the fuel use of about -5.15% (from 17.19 liters/hour to 16.30 liters/hour).
