OPTIMALISASI KINERJA SIMPANG BERSINYAL DENGAN KOORDINASI SIMPANG STUDI KASUS SIMPANG GUNUNG LATIMOJONG DAN SIMPANG VETERAN UTARA

The North Veteran Intersection and the Gunung Latimojong Intersection are two adjacent intersections with a distance between the intersections of 400 meters. At the level of service, this intersection received an F value on the Intersection Service Level Index, due to the distance between the intersections being close to the high traffic volume. One possible solution is to coordinate signals at the two intersections. The aim of this research is focused on reducing delays, high queue lengths and exhaust emissions produced by vehicles on the section connecting the two intersections. The signal coordination method is carried out using CTMC survey data, Spot Speed, Queue Length, MCO and performance calculations are carried out using PKJI 2023, then it will be continued with existing performance analysis and signal coordination with the Vissim application. So that the resulting model and volume are the same as those in the field, a calibration and validation process is carried out with statistical tests using GEH and MAPE. If the results issued are valid, it will continue with performance calculations and signal coordination analysis with the Vissim application. From the results of the analysis after coordination, there has been a decrease in queue length on the west approach of Simpang Veteran Utara by 69.44% and a decrease in delays by 77.77%, and there has been a decrease in queue length on the east approach of Simpang Gunung Latimojong by 30.13% and time delays as much as 49.04%. For the West approach of Simpang Veteran Utara, there was a decrease in ISPU CO by 82.98% and ISPU NOx, namely 53.67%. For the East approach to Simpang Gunung Latimojong, there was a decrease in ISPU CO by 63.%% and ISPU NOx, namely 36.22%.
