Abstract

Traffic flow at the intersection with traffic lights on Jalan Jend. Ahmad Yani Utara-Jalan Raden Intan, Blimbing, Malang, is often disrupted due to significant congestion and traffic delays. This study aims to evaluate the performance of the intersection and examine the traffic light operation model using PTV Vissim microscopic simulation software. The data collected included primary and secondary data. Primary data included vehicle volume, physical characteristics of the intersection, queue length, vehicle speed, and traffic light cycle. Secondary data was obtained from digital maps and documents related to road capacity. The research method used was quantitative descriptive with a simulation approach. The analysis was conducted based on a traffic flow of 3,877 pcu/hour, a saturation level of 3.57, an average queue length of 335.76 meters, a traffic delay of 54.95 seconds per vehicle, and an average vehicle speed of less than 36.7 km/hour. Furthermore, driver behavior parameter calibration was performed to ensure the accuracy of the model. With a GEH value of less than five, the PTV Vissim model proved to be valid and capable of accurately describing real traffic conditions. The results of this study indicate that simulation models can be used to design and evaluate traffic light control strategies, thereby improving vehicle flow and reducing queues and delays at the intersection.

These findings can also serve as a basis for decision-making related to traffic management in the urban area of Malang.

Abstract

The Seputuk and Rian Watersheds in Muruk Rian Subdistrict, Tana Tidung Regency, North Kalimantan Province, are areas that are prone to flooding due to high rainfall and the morphological conditions of the watersheds. This study aims to analyze and compare the planned flood discharge on the Simpang Seputuk Road section using the Snyder Synthetic Unit Hydrograph (HSS) and Nakayasu HSS methods. The data used is the maximum daily rainfall from the Salap Rainfall Station during the 2008–2021 period. The planned rainfall analysis was carried out using the Gumbel and Log Pearson Type III probability distributions, followed by a suitability test using the Chi-Square and Smirnov Kolmogorov methods. The selected planned rainfall was transformed into effective rainfall as input in the flood discharge calculation. The analysis results show that the Nakayasu HSS method produces a higher peak discharge than the Snyder HSS method in both watersheds. In the Seputuk watershed, the Nakayasu method's peak discharge for a 25-year return period reached 501.80 m³/sec, while the Snyder method produced 233.47 m³/sec. Meanwhile, in the Rian watershed, the Nakayasu method produced a peak discharge of 319.83 m³/sec and the Snyder method produced 73.06 m³/sec. This difference shows that the Nakayasu HSS method is more conservative and sensitive to watershed morphometric characteristics, making it more suitable for flood control planning in areas with flood risk. Meanwhile, in the Rian watershed, the Nakayasu method produced a peak discharge of 319.83 m³/sec and the Snyder method produced 73.06 m³/sec. This difference indicates that the Nakayasu HSS method is more conservative and sensitive to the morphometric characteristics of the watershed, making it more suitable for flood control planning in areas with high flood risk, while the Snyder method can be used as a preliminary estimate in watersheds with limited data.
