Abstract: The imbalance between the growths of the number of vehicles with road capacities makes this condition create traffic especially at the junction area to become the traffic crosses into the peak hour. This study was conducted on the unsignalized intersection Jalan Haji Bau-JalanPenghibur-JalanRajawali and this work focused on forming simulation model parameters, intersection performance characteristics, and optimizing intersections. This research was conducted at the intersection of Jalan Haji Bau-JalanPenghibur-JalanRajawali during working time which started at 06.00-18.00 Wita. This study requires data of vehicle characteristics and road geometric. Survey method used for volume measurement and for speed measurement using speed gun. The analytical method used to calculate the traffic performance of the intersection in this study is the approach of the Vissim-based traffic micro-simulation model to calculate the intersection performance by calibration using GEH Test on vehicle volume parameters and then validating the length of the vehicle queue using Chi-Square test. Based on the simulation result that the calibration parameter of each time period is the same and different like the vehicle safe distance parameter, the queue length and delay value at Jalan Haji Bau, Jalan, Penghibur, and JalanRajawali are 138.78 m and 40 sec; 19.46m and 19 sec; 53.52 m and 18.95 sec. Furthermore, traffic engineering efforts conducted with 2 types of alternative changes to a signal intersection where in this study the first alternative condition is considered to produce better intersection performance than the existing conditions and the second alternative.
