Analisis Tundaan Dan Panjang Antrian Akibat Penutupan Palang Pintu Kereta Api Dengan Menggunakan Metode Greenshield Dan Shockwave (Studi Kasus Jalan Raya Kubangkangkung Cilacap)

The intersection of crossings is formed between two means of transportation, namely highways and rail roads, which often cause problems. the same is the case at the intersection of crossings on the Kubangkangkung Cilacap highway which has problems, namely delays and queue lengths when the train door bars are closed. The purpose of this study was to determine the relationship between volume, speed, and density due to the closing of train door bars and determine the value of delays and the largest queue length that occurred due to the closing of train door bars at the research location.This research uses a survey method, namely by making direct observations to the research location to obtain data as a reference for analyzing. After the data is collected, analysis is carried out using the greenshield method to calculate the relationship between volume, speed and traffic density, and the shockwave method to calculate the value of delays and queue length due to the closing of train door bars. The results of the study stated that based on data in the field, the relationship between volume, speed and density is very strong. The largest queue length value (Qm) on Sunday in the Kawunganten - Cilacap direction at 11.11 was 0.38 km, with a duration of closing the train door bars for 220 seconds and a delay (stopped delay) for 330.3 seconds, the time needed to release the queue (tb) was 264.8 seconds.
