Abstract

This study evaluates the existing conditions of the Jalan Imam Bonjol along with the three intersections’ performance located within the corridor. The existing condition of the road segment was analyzed using PKJI 2023. The degree of saturation was found to be 0.38 on weekdays, while it was 0.52 on weekends. Although the road segment is not saturated yet, the operational speed data on weekdays show values of 5.3 km/h in the east–west direction and 4.9 km/h in the west–east direction. Meanwhile on weekends, the operational speeds are 6.4 km/h in the east–west direction and 4.9 km/h in the west–east direction. The operational vehicle speeds during peak hours are below the average speed of urban roads according to PKJI 2023, which is 20–50 km/h. Therefore, this study implements a traffic engineering by applying one-way system on one of the intersection approaches, namely Jalan Pisang, through microscopic simulation using the PTV VISSIM. The simulation of the existing condition shows the operational average speed reached 7.43 km/h, average delay was 11.31 seconds, and the average queue length was 4.04 m. Meanwhile, the one-way system simulation on Jalan Pisang resulted in significant changes, namely the average speed reached 7.62 km/h, the average delay amounted to 9 seconds, and the average queue length was equal to 3.82 m. This indicates that the traffic engineering scenario has the potential to improve the performance of the road segment and intersections.

Abstract

Based on direct observations at the pelican crossing located on Jalan Raden Intan, Bandar Lampung, despite the presence of pedestrian crossing facilities, many vehicle users do not stop or give way to pedestrians. Additionally, there are issues with pedestrian behavior, including disorderly crossing. Therefore, it is necessary to analyze the effectiveness of the pelican crossing on Jalan Raden Intan, Bandar Lampung, based on public perceptions, pedestrian crossing volume, the impact of traffic on pedestrians, the adequacy of crossing facilities, and to propose improvements for the pelican crossing. The analysis was conducted using questionnaires with indicators of safety, comfort, security, convenience, and accessibility. Effectiveness analysis was performed using PV2 calculations and traffic impact analysis on pedestrians. The results from the questionnaires indicated that the pelican crossing is very ineffective in terms of safety, comfort, security, convenience, and accessibility. The PV2 value of 1.46 x 109 suggests that Jalan Raden Intan, Bandar Lampung, requires a pelican crossing with a waiting area. The effectiveness analysis yielded scores of 54.66% and 50.44%, indicating that the pelican crossing at the observed location is categorized as ineffective. The traffic impact analysis showed that vehicle speeds before, during, and after the crossing do not decrease significantly, only reducing the speed of vehicles in the presence of pedestrians. Recommendations from this study include planning pedestrian crossings for individuals with special needs.
