EVALUASI KINERJA SUATU SIMPANG BERSINYAL DI KOTA BANDUNG

Abstract   The population of Bandung City which increases every year causes traffic congestion problems, especially at many intersections, including signalized intersections. This study was conducted on a signalized intersection located on Jalan Soekarno Hatta-Mohammad Toha, in the City of Bandung. The data used is data obtained directly from the field, and the analysis was carried out with the help of the Vissim Program. This study shows that the majority of motorbikes move at an intersection with a speed of 35 km/hour. While the majority of light vehicles, buses, and heavy vehicles move at speeds of 36 km/hour, 39 km/hour and 35 km/hour respectively. During traffic congestions, the longest queues at this intersection occur at the intersection of Jalan Mohammad Toha towards U-S, with a length of 226 meters and an average of 186.14 m/hour, and at the intersection of Jalan Mohammad Toha towards S-U, with a length of 226 meters and an average of 116.57 m/hour.   Keywords: signalized intersection; cross arms; speed; traffic congestion; queue     Abstrak   Jumlah penduduk Kota Bandung yang bertambah setiap tahun menimbulkan masalah kemacetan lalu lintas, khususnya di banyak simpang, termasuk di simpang bersinyal.
