Diponegoro Highway – Setia Mekar Street Bekasi Regency is access to the main road to the city border, besides that access to residential locations, schools, and many companies which makes vehicle traffic especially during rush hour more congested by the activities on the side of the road such as slow vehicle, the ups and downs of passengers, so vehicles that stop causing long vehicle queues. From the results of the analysis, the results of signalized intersection can be obtained on the Diponegoro Highway Setia Mekar Street Bekasi Regency. It is known that the greatest Degree of Saturation is in the Northen approach which is 1,12 with a average intersection delay is 99,21 seconds/smp. Furthermore, Alternative solutions is carried out by changing side obstacles from 0,94 to 0,95 and recycling time intersection, resulting in a decrease in the average intersection delay and improvement of indoporlen intersection services Keywords Delays, Degree of Saturation, MKJI 1997, Roads, Signalized Intersection 1. Introduction According to MKJI, 1997, Congestion is a condition where traffic flow passes by in the road section under review exceeded the capacity of the road plan resulting in the free speed of the road is close to or exceeding 0 km/hour, so that cause a queue to occur. At the time of the traffic jam, the degree of saturation on the road section will be reviewed where congestion will occur when the value of the degree of saturation more than 1. From several locations with density, one of which is Diponegoro Highway – Setia Mekar Street where density often occurs at the intersection. Because Diponegoro Highway – Setia Mekar Street is a main roads to the city, besides that this road is also an access to residential locations, schools, and companies which makes traffic on this road congested with the activities on the side road which is quite high such as slow vehicles, the ups and downs of passengers, so vehicles that stop causing long queues.

Signalized intersections Source: Researcher's Documentation, 2021 Based on these problems, and causes listed in the identification of the problem that has been discussed, as for the problems that will be discussed, What is the volume of vehicles and capacity at the Intersection Indoporlen Bekasi? How is the performance of signals intersections at the Indoporlen Intersection Bekasi dan Diponegoro Highway? What are the solutions to improve the performance Intersection Indoporlen and Diponegoro Highway?
