Traffic Management and Engineering Analysis of the Manahan Flyover Area by using Traffic Micro-Simulation VISSIM

Abstract

The location of the Manahan railway level crossing is a meeting point for movement between trains and vehicles which often causes traffic congestion and traffic accidents in the area. In connection with the construction of the double track railway, the intensity of traffic congestion in the Manahan railway level crossing area is increasing. In order to overcome traffic congestion in the area, the Surakarta City Government built Manahan Flyover infrastructure. However, due to traffic management and engineering in the existing conditions is not optimal resulting in a relatively bad traffic congestion in Manahan Flyover area. The aim of this study is to conduct traffic management and engineering analysis to minimize traffic congestion in Manahan Flyover area. The traffic micro-simulation VISSIM model is used to evaluate the performance of road networks at peak traffic conditions with different simulation model scenarios. The existing model is built based on a field survey data and then calibrated it to approximate conditions on the field. Then based on the existing model, modelling of several traffic management and engineering scenarios are carried out to obtain the optimal performance of the road network in the Manahan Flyover area. The analysis shows that the simulation model Scenario 3 produces the best performance of road network in terms of vehicle delay, queue length, travel time and speed
