PEMODELAN SIMPANG TAK BERSINYAL MENJADI SIMPANG BERSINYAL MENGGUNAKAN SOFTWARE PTV VISSIM

(STUDI KASUS : SIMPANG EMPAT SENTOSA BATURAJA)

Abstract

With the increasing population growth from year to year, it will have an impact on the transportation sector, one of which is the conflict of traffic flow at road intersections. In Baturaja city, there are several intersections that have not been equipped with signaling (traffic lights), one of which is Simpang Empat Sentosa. At the intersection there are traffic lights but they have not been functioning for a long time, besides this intersection has quite busy traffic flow conditions, especially during peak hours. This research aims to analyze the intersection performance through unsignalized intersection modeling and signalized intersection modeling. The method in this study is to conduct a direct traffic survey in the field which is then followed by modeling with the help of PTV Vissim software. The results of modeling the existing condition intersection obtained level of service (LOS) C, average delay value of 15.07 seconds / vehicle, average queue length of 7.76 meters, and maximum queue length of 51.69 meters. The second modeling is the intersection modeling of signalized conditions obtained level of service (LOS) C, average delay value of 28.67 seconds / vehicle, average queue length of 12.30 meters, and maximum queue length of 62.07 meters. From the two intersection modeling that has been made, it can be seen that the condition of the intersection without a signal is better than when given signaling (traffic lights).
