Kentungan Intersection is an intersection that always having a traffic jam at the peak hours. Traffic congestion at Kentungan Intersection is caused by highly vehicle volume exceeding the intersection capacity. The type of this intersection is flat intersection. Thus, its need to evaluate from geometric view with the ways of changing the type of the intersection to elevated intersection (interchange). Elevated intersection is consisting of conventional and unconventional. Elevated conventional intersection is commonly used in Indonesia like flyover or underpass. This study chooses one of the unconventional intersections called Single-Point Urban Interchange (SPUI). SPUI provides vehicle movement more and efficiently than others type. The purpose of this study is to get modelling result from three intersections condition. Method used in this study is modelling using program PTV.VISSIM 9. This study models a three condition; existing condition, Default SPUI Intersection, and Modification SPUI Intersection. Result of the modelling existing condition, level of service of the intersection is LOS F with the average vehicle delay is 104,79 second. On Default SPUI Intersection, level of service of the intersection is LOS D with the average vehicle delay is 32,54 second. On Modification SPUI Intersection, level of service of the intersection is LOS D with the average vehicle delay is 30,3 second. Result of this models are passing the calibration process from driving behavior aspect and vehicle volume validation and the best result is SPUI with size modification.
