PEMODELAN SIMPANG BERSINYAL AKIBAT PERUBAHAN URUTAN FASE DENGAN SOFTWARE PTV VISSIM PADA SIMPANG EMPAT BERSINYAL SENOPATI YOGYAKARTA
Abstract
Yogyakarta is a city whose development is quite rapid, this has an impact
on the increasingly congested traffic flow, especially at the crossroads that often
occur congestion. Like the Senopati intersection in Yogyakarta, traffic jams often
occur at rush hour. The use of phase sequences in the APILL system still uses a
clockwise phase sequence. This study aims to analyze the performance of
intersections after the change of phase sequence of APILL lamp using VISSIM
software. The data used in this research is using traffic survey method and other
supporting data (environmental condition, road geometric) in field and modeling
using VISSIM 10.0 program. Based on the modeling results can be known
intersection performance on the existing condition is at service level F and the value
of delay 115.5 seconds / vehicle. After several scenarios are carried out, an effective
phase sequence is obtained when the turn ratio at the intersection reaches 90% for
the right turn ratio and 10% for the straight and east arm ratio with a delay value of
70.29 seconds / vehicle and service level E.
