Arterial Road Service Evaluation Using the Ideal Flow Network Method: A Case Study in Malang

Abstract

The current government of Greater Malang continues to work hard to balance the density of land transport traffic to create better traffic flow and still encourage and improve its economy. Moreover, in recent years, INRIX has rated Malang as the third most congested city in Indonesia after Jakarta and Bandung. This study aims to identify factors and potential points of congestion on complex roads in the research object area. The research methodology uses literature studies, spatial databases, and data collection techniques by conducting surveys at each point of the research location with annual average daily traffic (AADT) for a month. The research location is on the arterial road in the city of Malang. The road network system is variable to analyze using the IFN methodology; the working concept of the Ideal Flow Network (IFN) method uses pre-magic equilibrium as an ideal pattern, where all roads will have the same ideally congestion level. This study provides an alternative solution to overcoming congestion and determining when and where the congestion will occur in the city of Malang. Based on the analysis results, it is concluded that the smallest weighting of traffic volume is founded in alternative route three at each node, value of the degree of saturation is 1.48; 0.74; 0.62; 0.49; 0.37; 0.24; 0.12. Then the value of the degree of saturation at each node is smaller so that the traffic flow becomes smoother.
