Micro-simulation analysis of traffic on underpass processing plan at the intersection of Mandai in Makassar

Abstract

The rapid growth of population in Makassar City directly increases the vehicles on road and causing traffic congestion. The intersection of Mandai in Makassar City experience heavy traffic flow condition and Mandai Underpass is developed. This study simulates and analyzes the condition of traffic flow at the Mandai intersection using the Mikro-Simulasi technique which is Vissim software program. The peak hour season of traffic flow is considered in this study which is morning (07.00–08.00), afternoon (12.00–13.00) and evening (16.00– 17.00). The calibration and validation process of the simulation model using the volume and length of the queue of vehicles in the field and GEH Test analysis (Geoffrey E. Havers). The simulation model was successfully demonstrated and results pass the Chi-square test. The result show that, Frontage Toll Road DR. Ir. Sutami has the longer queue length in morning about 342.45m, while Makassar-Maros Axis Road has the longer queue length in afternoon and evening which is 503.49m and 602.69m respectively.
