Micro-simulation of traffic at the 3-way junction with PTV VISSIM software (Jalan A.P. Pettarani-Jalan Boulevard-Jalanpelita Raya)

Abstract

This study aims to determine the traffic performance at 3-way junction of Jalan A.P. Pettarani-Jalan Boulevard-JalanPelita Raya. The study conducted a survey to obtain the geometric data and vehicle volume and then analyzed using PTV Vissim software which refers to the calibration process and validation of the simulation model using the volume and length of queues of vehicles in the field. The calibration was carried out by trial and error by considering the driver's behavior follow by the GEH Test on the vehicle volume. The simulation result was validated by Chi-Square Test on the length of the vehicle queue. Furthermore, traffic engineering is conducted with optimization of phase time and cycle time whereby optimization with increasing the cycle time from 105 seconds to 120 seconds demonstrated better traffic performance than the existing traffic performance.
