A Optimizing Toll Exit Design for High-Speed Rail Accessibility Using VISUM Traffic Modeling

Abstract

Improving accessibility to high-speed rail stations is essential for ensuring efficient and integrated transportation systems. Tegalluar Station, part of the Jakarta–Bandung High-Speed Railway network, is currently served by toll exits that were not designed for high traffic demand, resulting in congestion and reduced network performance. This study aims to evaluate and optimize toll exit configurations to improve accessibility to Tegalluar Station. Traffic modeling and scenario analysis were conducted using PTV VISUM, supported by calibrated origin–destination matrices and evaluated through Multi-Criteria Analysis. Four development alternatives were assessed based on traffic volume, queue length, travel time, network performance, spatial constraints, and cost. The results show that the full-access scenario combining the existing KM 149 toll exit with additional on–off ramps at KM 151 generates the highest traffic demand, reaching 19,956 vehicles per day, while also improving traffic distribution across the network. However, multi-criteria evaluation indicates that a staged development strategy provides the most effective and feasible solution. Gradual implementation starting from optimization of existing access significantly reduces congestion and improves accessibility without overloading the surrounding road network. These findings demonstrate that simulation-based and multi-criteria planning offers a robust decision-support framework for toll exit design supporting high-speed rail accessibility.
