Analysis of Signalless Four-way Intersection Congestion at Jalan Kyai Sampang, Demak Regency

An intersection is a part of a road segment where currents from various directions or directions intersect. This results in congestion along the intersection arm. This intersection is located in the center of Demak Regency, an unsignalized intersection with 4 arms on Jalan Kyai Sampang, Jalan Kyai Singkil, Jalan Sultan Fatah towards Kudus and Jalan Sultan Fatah towards Semarang which is located in the market area, offices, residential areas and schools. This research was conducted to determine the performance of the intersection, especially with regard to the operational conditions of the intersection as indicated by the value of capacity, degree of saturation, delay, and queuing opportunities. Then after the analysis, it is also obtained that the capacity value at the intersection is 1634 smp/hour. Analysis of the value of the degree of saturation (DS) obtained DS results amounted to 0.79 smp/hour. Delay analysis (D) results in a delay of 13.33 smp/hour. Then the analysis of queuing opportunities obtained the results of queuing opportunities of 64.6% - 132.5%.Persimpangan adalah bagian dari ruas jalan dimana arus dari berbagai arah atau jurusan bersilangan. Hal ini mengakibatkan terjadinya kemacetan di sepanjang lengan simpang. Simpang ini berada di pusat Kabupaten Demak, simpang tak bersinyal dengan 4 lengan di jalan Kyai Sampang, jalan Kyai Singkil, jalan Sultan Fatah arah Kudus dan jalan Sultan Fatah arah Semarang yang berada pada daerah pasar, perkantoran, pemukiman dan sekolah . Penelitian ini dilakukan untuk mengetahui kinerja simpang terutama yang berkaitan tentang kondisi operasional simpang yang ditunjukan dengan nilai kapasitas, derajat kejenuhan, tundaan, dan peluang antrian. Kemudian setelah di analisis, didapat pula nilai kapasitas yang ada di persimpangan tersebut berjumlah 1634 smp/jam. Analisa nilai derajat kejenuhan (DS) didapat hasil DS berjumlah 0,79 smp/jam. Analisa tundaan (D) didapat hasil tundaan 13,33 smp/jam. Kemudian analisa peluang antrian didapat hasil peluang antrian sebesar 64,6% - 132,5.   &nbsp
