Abstract

Urban superblocks integrating mixed-use developments generate substantial traffic volumes that threaten to overwhelm existing arterial networks in rapidly urbanizing cities. This study evaluates the operational traffic impacts of the Pakuwon superblock development in Bekasi, Indonesia, using PTV VISSIM microsimulation calibrated against Indonesian Road Capacity Guidelines (PKJI 2023). The research employs a hybrid methodology combining traffic engineering interventions with transportation demand management (TDM) strategies following the Avoid-Shift-Improve (ASI) framework. Baseline simulations reveal catastrophic network failure without mitigation, with volume-to-capacity (V/C) ratios reaching 1.81 and Level of Service (LOS) F on critical arterial segments. The study tested four alternative scenarios, with Alternative 3 (flyover construction combined with comprehensive TDM measures achieving 10% private vehicle reduction) demonstrating optimal performance. Post-mitigation simulations show V/C ratios reduced to 0.69 (average 47% improvement), speeds increased by 36%, and LOS improved to C-D across all segments. Findings demonstrate that integrating physical infrastructure improvements with binding demand management policies is essential for sustainable urban development in congested Asian cities. The research contributes a replicable methodological framework for traffic impact assessment that transcends conventional geometric-only approaches.

Abstract

Urban congestion represents a critical challenge in metropolitan transportation systems, particularly in one-way traffic corridors experiencing geometric bottlenecks. This study evaluates the implementation of one-way systems on Jalan Gading Indah Raya and proposes evidence-based intervention models to enhance traffic performance at Pintu Satu Gading, North Jakarta. Employing mixed-method triangulation, the research integrates field surveys, Indonesian Road Capacity Manual (PKJI) analysis, and PTV Vissim microsimulation modeling to assess existing conditions and evaluate intervention scenarios. Field data revealed peak traffic volumes reaching 6,804 vehicles per hour with speeds declining to 16 km/h, indicating severe saturation conditions. Three intervention scenarios were simulated, incorporating geometric modifications, signal timing optimization, and traffic management strategies. Results demonstrate that integrated interventions can improve degree of saturation by 23-31%, enhance average speeds by 18-27%, and elevate the level of service from D/E to B/C categories. The study validates microsimulation as an effective tool for evaluating traffic interventions in complex urban networks and provides actionable recommendations for transportation authorities managing geometric bottlenecks in one-way arterial systems.
