Abstract

Congestion in urban areas is not only influenced by the high volume of vehicles, but also by U-Turn maneuver activities that can cause conflicts and reduce traffic performance. This study aims to evaluate the effect of U-Turn facilities on road performance and provide recommendations for handling them. The method used is microscopic simulation using PTV VISSIM software, with reference to evaluation parameters based on the 2023 Indonesian Road Capacity Guidelines (PKJI), namely the degree of saturation (DJ), delay, and Level of Service. The results of the study indicate that in the next 10 years there will be a decline in the performance of the analyzed U-Turn. This study analyzes 3 (three) alternative handling solutions in the form of traffic management on U-Turns and produces the best recommendations in the form of full opening of U-Turns 1 and 4, partial closure of U-Turns 2, and full closure of U-Turns 5 and 6 which can improve traffic performance on U-Turns to be more optimal (reducing delay values and increasing Level of Service values).

Abstract

The development of urban traffic in the city of Cirebon poses challenges to the performance of signalized intersections, particularly at the Gunung Sari intersection, which connects four main corridors: Jl. Cipto Mangunkusumo, Jl. Wahidin, Jl. Tuparev, and Jl. Kartini. This study aims to evaluate the existing performance of the intersection using a manual approach based on the 2023 Indonesian Road Capacity Guidelines (PKJI) and microscopic modeling with PTV VISSIM software. The survey was conducted by recording traffic volume for 5 days between 06:00 and 18:00 WIB, with peak conditions occurring on Saturday between 13:00 and 14:00 WIB at 8,082 vehicles/hour. The traffic composition was dominated by motorcycles (59.54%) and passenger cars (39.03%). The results of the 2023 PKJI analysis showed that all intersection arms in the existing condition were at service level F with an average delay of 92.24–98.24 seconds and a queue length of 76.63–204.84 meters. The 10-year projection shows an increase in the degree of saturation to >1.80 with the highest delay on the Kartini arm of 436.33 seconds. Validation of the VISSIM model using the GEH test produced a value of <5 with a conformity level above 95%, so the model is reliable. The simulation results show that Scenario 1 (simplifying the cycle to 3 phases by combining Wahidin and Cipto) is the most effective alternative because it can reduce the average delay and queue length evenly compared to other scenarios. This study emphasizes the importance of periodic evaluation and the application of simulation-based scenarios in supporting urban traffic management.

Abstract

Level crossings are a persistent source of traffic congestion and vehicular emissions in many urban areas, particularly in mid-sized cities where road and rail networks intersect at grade. This study investigates the impact of level crossing operations on vehicle CO₂ emissions by analyzing traffic delays caused by train movements at nine crossings in Cirebon City, Indonesia. Using field observations, four traffic-related variables were collected: train frequency (crossings/day), average waiting time (seconds), queue length (meters), and idle vehicle count (vehicles/day). Emissions were estimated using the IPCC Tier 1 methodology, and a multiple linear regression model was developed to assess the relationship between traffic conditions and daily CO₂ emissions. The results show that train frequency and idle vehicle count are statistically significant predictors of emissions, with each additional train and idle vehicle contributing substantially to total CO₂ output. While waiting time and queue length were less significant, their influence was observed to be moderated by vehicle type and traffic density. The regression model explains 99.6% of the variance in emissions (Adjusted R² = 0.996), underscoring the strength of the identified predictors. This study highlights the need for localized emission mitigation strategies, such as optimizing train schedules, improving traffic flow near crossings, and accounting for vehicle composition in emission control policies. The methodology and findings provide a practical framework for traffic-environmental assessments in similar urban settings.
