In order to make good decisions in transportation, decision-makers need some references to support the decision. One source for such reference is to perform a micro-simulation; a model for representing real-world conditions including the behavior of travelers, vehicles and the infrastructure. This study examines and presents a comparison between AIMSUN (a commercial micro-simulation software) and Indonesia Highway Capacity Manual 1997(IHCM-1997) in relation to the road traffic performance of the study object Södra länken, E266 and E75, in south part of Stockholm, Sweden. A calibration process is conducted in order to find the best value of a set of parameters in each software. The best set of parameters was selected based on the lowest value of a Root Mean Square Error (RMSE) computed based on observed speed data and the model output. The parameters is then validated using evening peak-hour data. The comparisons were conducted in the term of flow, speed and density by AIMSUN, IHCM-1997 and the observation data on morning and evening peak-hour. This research gave result that from the given experiments with the AIMSUN software with the best set of parameters was when the value of Maximum Desired Speed at 100 km/h and Speed Acceptance at 1,1. The result showed that the significant different between AIMSUN, IHCM-1997 and observation lays on the speed. IHCM-1997 gave relatively higher speed than both AIMSUN and observation data.
