Performance Analysis of Unsignaled Intersection JL. Menganti - Jl. Darkun - Jl. Pahlawan Mubin Wonokoyo Gresik Regency

Abstract

The increasing movement of transportation is one of the main causes of traffic congestion. Traffic congestion in Gresik Regency is often found on several highways, one of which is at the unsignalized intersection of Menganti road with the conditions around the intersection being a commercial area. Therefore, efforts are needed to overcome congestion by studying and analyzing the conditions and performance of the unsignalized intersection on Menganti road so that the feasibility of an unsignalized intersection can be determined. Data in the form of population data, geometric data, traffic flow data, and side obstacle data are then analyzed using the unsignalized intersection calculation formula that has been included in the Indonesian Road Capacity Guidelines (PKJI) 2023. The results of the research on the performance of the unsignalized four-way intersection of Menganti road were obtained as follows: The highest Average Daily Traffic (ADR) was on Wednesday, May 7, 2025, which was 2500.846 vehicles/hour; peak traffic hours occurred at 07.00-08.00; The highest Degree of Saturation (DJ) was on Monday, May 5, 2025, which was 0.91231 with a Capacity (C) of 3095 vehicles/hour, Delay (T) of 17.76845 sec/vehicle, Queue Opportunity (PA) of -1.00%-65,86%. The solutions that can be provided are to install traffic lights, widen each approach and implement a one-way system on approach D (Pahlawan Mubin Wonokoy road) and divert it to Sidomulyo road.
