Optimization of Road Section and Signalized Intersection Performance Using PKJI 2023 at Dewi Sartika-Raya Kalibata Intersection

As time goes by, population growth and the need for transportation will increase. The increase in the number of vehicles on the road that is not accompanied by improvements in transportation infrastructure such as roads is one of the reasons for congestion. There are many congestion points in East Jakarta, one of which is at the intersection of Jl. Dewi Sartika-Jl. Raya Kalibata. The purpose of this study is to analyze the performance of road sections and signalized intersections of Jalan Dewi Sartika, Kramat Jati East Jakarta and provide alternative solutions for the performance of signalized intersections (APILL) Jalan Dewi Sartika-Jalan Raya Kalibata, Kramat Jati East Jakarta. Conducted using the traffic counter method and using calculations on the Indonesian Road Capacity Guidelines 2023 (PKJI 2023). The results of the analysis of the performance of the signalized intersection under existing conditions are the degree of saturation value for the north arm 0.771, the south arm 0.919, and the west arm 1.042 in the afternoon peak hour. The queue length for the north arm is 136.99, the south arm is 153.76, and the west is 165.67 meters long. The average intersection delay is 81 seconds /mp so that the level of service is classified in category F. Alternative solutions, namely by making all left turns on the west arm, get the results of the degree of saturation value for the north arm 0.702, and the south arm 0.527 in the afternoon peak hour. The queue length for the north arm is 44.22, the south arm is 27.84. The average intersection delay is 14 seconds / smp and the level of service of the intersection at the afternoon peak hour is category C. And the results of the performance of the Jl. Dewi Sartika section obtained the results of the degree of saturation in the direction of Cawang 0.46, and the degree of saturation in the direction of Kp. Melayu 0.73. The level of service is classified as C
