Abstract

The Bacharuddin Jusuf Habibie Road, which underwent improvements compared to the previous year, has not yet experienced traffic congestion. However, with increasing vehicles, congestion will likely occur in the coming years. Objective: To analyze the road characteristics, including geometric features, speed, travel time, traffic volume, and composition; road performance, free-flow speed, density, road capacity, degree of saturation, and level of service; and simulation results using VISSIM software. Methodology: The study utilized both primary and secondary data. Primary data were collected through field observations, while secondary data were sourced from journals, books, and government agencies. Results: The analysis shows the highest traffic volume occurs on Tuesdays between 16:00-17:00, with a total volume of 2,710 vehicles/hour or 1,117.8 passenger car units (PCU)/hour, predominantly consisting of motorcycles (82.32%), followed by sedans (11.77%), passenger vehicles (0.01%), pickup trucks (4.78%), small and large buses (0.19%), two-axle trucks with 4 and 6 wheels (0.92%), and articulated trucks (0.01%). Conclusion: The performance analysis of the Bacharuddin Jusuf Habibie Road in Bone Bolango Regency, utilizing the PKJI (Indonesian Highway Capacity Manual) 2023 method, reveals a free-flow speed of 46.269 km/h, a traffic density of 2.08 vehicles/hour/m, a road capacity of 1,484 PCU/hour, degree of saturation of “0.38” indicates a stable flow with very good condition and is categorized as A. Then, the level of service D is observable from vehicles speed according to the Government Regulations of 2015

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.

Abstract

Jalan Jenderal Sudirman adalah salah satu ruas jalan di Kota Gorontalo yang memiliki volume kendaraan yang besar. Keadaan ini diperparah oleh banyaknya kendaraan yang parkir di sepanjang badan jalan. Tujuan dari penelitian ini untuk mengetahui kinerja dari ruas Jalan Jendral Sudirman akibat adanya parkir di badan jalan. Dalam penelitian ini MKJI 1997 digunakan sebagai pedoman dalam menganalisis kinerja ruas jalan. Penelitian ini dilangsungkan selama 3 hari yaitu hari Selasa, 11 Juni 2024, Jumat, 14 Juni 2024, dan Sabtu, 15 Juni 2024. Hasil kondisi eksisting yang didapatkan yaitu tingkat pelayanan jalan terburuk terdapat pada hari Selasa, 11 Juni 2024 dengan nilai derajat kejenuhan sebesar 0,58 dan masuk pada kategori tingkat pelayanan jalan C, serta pada kondisi jika tidak terdapat parkir di badan jalan tingkat pelayanan meningkat menjadi 0,30 dan masuk pada kategori B. Hasil ini menunjukan bahwa kegiatan parkir di badan jalan sangat berpengaruh pada optimalnya kinerja ruas jalan.

Abstract

Road damage is a complex problem and can cause major losses for road users.The purpose of this study is to analyze the damage to the Molingkapoto road at the Kwandang intersection, and to examine the appropriate handling of the damage that occurs. The methods used in the study are the SDI and IRI methods. The SDI method is a visual assessment of damage conditions. In calculating the SDI value, 4 elements are used, namely % crack area, crack gap width, number of holes/100 m and depth of wheel ruts. The IRI method is the value of road surface flatness calculated from the cumulative number of ups and downs of the longitudinal profile surface divided by the distance/length of the measured surface. The IRI value in this study was taken per 100 m using the Roadlab Pro application. The results of the SDI method analysis showed good conditions of 82%, moderate 12%, minor damage 3%, and severe damage 3%. The road conditions were dominated by good conditions along 2.7 km. The results of the IRI method analysis showed very good conditions of 0%, good conditions of 68%, moderate 29%, bad 3%, and very bad 0%. The road conditions were dominated by good conditions along 4.5 km. The combination of SDI and IRI values showed that Molingkapoto road at the Kwandang intersection sta. 6+300 to sta. 9+600 was in moderate condition and only required routine maintenance.
