Abstract

The solution to the transportation problem lies in assessing the performance of related road sections and intersections, and analyzing different traffic management schemes to optimize efficiency. This study aims to compare the performance of a road network simulation model for the Pahlawan road area. Data analysis includes examining origin-destination matrices, vehicle free speeds, vehicle behavior, and intersection control. The simulation model, calibrated and validated using Vissim, represents real-world conditions. Implementing SLFF (Single Lane Free Flow) and MLFF (Multi Lane Free Flow) systems at toll gates (scenarios 1 and 2) reduced queues, particularly at the Pancasila Monument Roundabout and Jalan Jati Raya. Adding a new toll gate via Jalan Kahuripan further improved traffic on Jalan Pahlawan compared to scenarios 1 and 2. However, converting the Gelora Delta roundabout into an underpass without additional measures worsened toll gate queues. Effective traffic performance can be achieved by combining the Gelora Delta roundabout underpass with either the SLFF toll payment system (scenario 5), MLFF (scenario 6), or the addition of a new toll gate (scenario 3).

Abstract

Based on the recapitulation of Transjatim Corridor I passengers in 2023, the average load factor is 120%, with an average of 5-6 thousand passengers per day, leading to the addition of a fleet with luxury services. This study aims to analyze the financial feasibility of investment in the Transjatim Luxury Bus Corridor I by comparing income and expenditure variables using the Net Present Value (NPV), Benefit-Cost Ratio (BCR), Internal Rate of Return (IRR), and Payback Period (PP) methods. With a 6% discount rate, the analysis yielded NPV values > 0 (Rp. 5,204,972,631 for alternative 1, Rp. 2,466,479,592 for alternative 2, and Rp. 640,817,566 for alternative 3), IRR values > 6% (19.42% for alternative 1, 12.54% for alternative 2, and 7.74% for alternative 3), and BCR values > 1 (1.30 for alternative 1, 1.19 for alternative 2, and 1.11 for alternative 3). The PP values were 4 years for alternative 1, 5 years for alternative 2, and 6 years for alternative 3, indicating that all three alternatives are financially feasible. Sensitivity analysis confirmed the financial feasibility of all three alternatives, considering the effect of the discount rate on NPV.
