Abstract

Diajukan 02 Agustus 2023 Diperbaiki 22 Agustus 2023 Disetujui 22 Agustus 2023 Traffic congestion occurred when signalized intersection relatively nearby level crossing. Two models of the relationship between variables were created, the first model is the relationship between train length, crossing closing time, and train speed using multiple regression methods. The second model is the relationship between the length of crossing closing time and the length of the queue using the regression method. The first model results obtained y =-16.72 x1 + 4.309 x2 + 436.237. With y = length of time to close a level crossing, x1 = train speed, and x2 = number of train cars. The results of the second model obtained y = 0.043x + 39.443 in the west-right approach to the real field, and y = 0.745x + 28.052 in the west-right approach the results of the calculation, with y = the closing time of the level crossing and x = the length of the queue of vehicles. This equation implies that 20 seconds of crossing time increases, it will increase the queue length by 40.30 m in real field conditions and 42.95 m in calculated conditions. Abstrak Kata kunci: perlintasan sebidang kereta api, panjang antrian, kinerja lalu lintas Persimpangan bersinyal yang berdekatan dengan perlintasan sebidang menyebabkan waktu tunggu lebih lama pada saat penutupan perlintasan sebidang, sehingga mengakibatkan kemacetan. Dibuat dua model hubungan antar variabel, model pertama adalah hubungan antara panjang kereta api, lama waktu penutupan perlintasan, dan kecepatan kereta api menggunakan metode regresi berganda. Model kedua adalah hubungan antara lama waktu penutupan perlintasan dan panjang antrian menggunakan metode regresi. Hasil model pertama didapat y =-16,72 x1 + 4,309 x2 + 436,237. Dengan y = lama waktu penutupan perlintasan sebidang, x1 = kecepatan kereta api, dan x2 = jumlah gerbong kereta api. Hasil model kedua didapat y = 0,043x + 39,443 pada pendekat barat kanan real lapangan, dan y = 0,745x + 28,052 pada pendekat barat kanan hasil perhitungan, dengan y = waktu penutupan perlintasan sebidang dan x = panjang antrian kendaraan. Persamaan tersebut mengandung arti 20 detik waktu perlintasan bertambah maka akan menambah panjang antrian sebesar 40,30 m pada kondisi real lapangan dan 42,95 m pada kondisi hasil perhitungan.
