Introduction

Evaluasi kinerja simpang bersinyal dan pengaturan ulang waktu siklus apill menggunakan ptv vissim. Evaluasi kinerja simpang bersinyal Jln. Raja Eyato - Moh. Yamin menggunakan PKJI 2023 & PTV Vissim. Analisis tunda lalu lintas menunjukkan LOS D/E. Solusi optimalisasi sinyal mengurangi tunda 33% tanpa biaya.

Abstract

The signalized intersection of Jalan Raja Eyato - Moh. Yamin A.R. Koniyo serves as a connection between commercial areas, tourist attractions, fast-food restaurant zones, and religious sites. As a result, this intersection experiences heavy traffic flow. Additionally, its asymmetric/weaving geometric design extends travel time from one approach to another. This study aims to evaluate the intersection's performance and level of service using the Indonesian Highway Capacity Guidelines (PKJI) 2023 and simulation modeling with PTV Vissim Student Version. The analysis results based on PKJI 2023 show the delay values as follows: Jalan Moh. Yamin at 49 seconds with level of service E, Jalan A.R. Koniyo at 38,1 seconds with level of service D, Jalan Raja Eyato (west) at 49,5 seconds with level of service E, and Jalan Raja Eyato (east) at 33,6 seconds with level of service D. The average intersection delay is 37 seconds, classified as level of service D. Meanwhile, the simulation results using PTV Vissim Student Version indicate delay values of 73,4 seconds with level of service E for Jalan Moh. Yamin, 72 seconds with level of service E for Jalan A.R. Koniyo, 46,3 seconds with level of service D for Jalan Raja Eyato (west), and 27,8 seconds with level of service C for Jalan Raja Eyato (east), with an average intersection delay of 54,5 seconds with level of service D. Four alternative solutions were proposed to improve the intersection's performance. The best solution is Alternative 2. which reduced signal phases four to three. This adjustment reduced delays by approximately 33% compared to current conditions, without requiring additional infrastructure costs.

Review

The submitted paper, "EVALUASI KINERJA SIMPANG BERSINYAL DAN PENGATURAN ULANG WAKTU SIKLUS APILL MENGGUNAKAN PTV VISSIM," addresses a critical issue in urban traffic management: the performance evaluation and optimization of a busy signalized intersection. The study focuses on the Jalan Raja Eyato - Moh. Yamin A.R. Koniyo intersection, which is strategically important due to its connectivity to various high-traffic generators like commercial areas, tourist attractions, and religious sites. The inherent challenges posed by heavy traffic flow and an asymmetric geometric design underscore the practical relevance of this research, aiming to improve traffic efficiency and reduce travel times. The methodology employed, combining the Indonesian Highway Capacity Guidelines (PKJI) 2023 with PTV Vissim Student Version simulation, provides a robust approach to assess the intersection's current operational status. Both methods consistently indicate significant delays and low levels of service (LoS D and E) across multiple approaches, confirming the urgent need for intervention. A key strength of this study lies in its proactive proposal of four alternative solutions. Notably, Alternative 2, which involves reducing signal phases from four to three, stands out as a highly effective and practical recommendation. The reported reduction of approximately 33% in delays without requiring additional infrastructure costs highlights the economic viability and immediate applicability of the findings, presenting a valuable contribution to local traffic engineering. While the abstract clearly outlines the problem, methodology, and primary solution, the full paper would benefit from a more detailed discussion regarding the discrepancies observed between the PKJI 2023 and PTV Vissim results. Elucidating the reasons behind these differences (e.g., differing assumptions, data input, model sensitivities) could offer deeper insights into the applicability of each method. Furthermore, discussing the specific parameters and calibration efforts for the PTV Vissim model, especially given it's a "Student Version," would enhance the credibility and generalizability of the simulation outcomes. Overall, this study offers a compelling analysis and a cost-effective solution for a problematic urban intersection, demonstrating significant potential for real-world impact. The paper appears well-structured and relevant, making a valuable contribution to the field of traffic engineering.
