The intersection is a place of conflict between vehicles of two or more roads. Driver behavior and land use also influence intersections. This is the cause of the need for studies for intersection management. One study for intersections is the calculation of the intersection capacity itself. The capacity to be assessed, of course, requires data on the volume of vehicles passing at the intersection. The purpose of this study was to analyze the performance of the weekly intersections in Merauke Regency by using the Indonesia Road Capacity(Kapasitas Jalan Indonesia: KAJI) program.Results of analysis of vehicle volume data passing for one week, the largest vehicle volume can be seen on Sunday at 17:00 - 18:00 WIT that is equal to 2038 vehicles / hour or 1153 pcu / hour. Calculation of intersection capacity using the KAJI application obtained a weekly intersection capacity of 2451 pcu / hour. The degree of saturation at a weekly intersection is 0.47. Based on the results of the analysis it can be concluded that the service level of the four unmarked intersections is at level C, ie the current is stable but the speed and motion of the vehicle is controlled and the driver is limited in choosing speed.
