Jakarta Outer Ring Road (JORR) Toll Road Off-Ramp Connectivity Queuing With Local Roads: A Case Study of T.B. Simatupang Road and JORR Toll Off-Ramp

TB Simatupang Road is one of the main arterial roads in South Jakarta, Indonesia, connecting various important areas. Efficient connectivity between major expressways and local roads is crucial for facilitating smooth traffic flow in urban areas. However, in some cases, the connection between toll road off-ramps and local roads experiences queues and traffic delays. This study aims to analyze the impact of off-ramps on local roads by incorporating the JORR Toll Road off-ramp and the signalized intersection at Fatmawati Street into the model in detail. The research methodology combines data analysis, traffic simulation, and field observations. Relevant traffic data, such as vehicle volume, average speed, and vehicle movement patterns, will be collected from the areas surrounding the toll road off-ramp intersection, TB Simatupang Road, and Fatmawati Road intersection. The results of the VISSIM simulation indicate that the degree of saturation exceeds 1, and the queue length reflects severe congestion. The conclusion is that to reduce congestion and improve traffic efficiency, an underpass should be constructed in the direction of Kampung Rambutan or from the off-ramp to Blok M. Additionally, eliminating lane merging is recommended to achieve smoother and more effective traffic flow.
