Optimization of Interception Coordination on Ir Road. Soekarno, Kediri, Tabanan Through A Microsimulation Approach

Abstract

Ir. Soekarno road area, Kediri, Tabanan Regency is an arterial road section that connects the Tabanan area to Jembrana Regency. The road section is a section of freight and public transportation between cities between provinces. Simpang Yeh Ganga, Simpang Dukuh, Simpang Kasih Ibu and Simpang Gerokgak have a distance between intersections of less than 800 meters which allows optimization of intersection coordination. The analysis carried out can obtain the performance value of the existing intersection before optimization, calculation of the coordination cycle time so that it can be applied using Vissim simulation in obtaining performance after optimization of the coordination cycle time. Validation is carried out by comparing the volume of segments at each intersection with an independent sample t-test statistical test with a significance value above 0.05 so that the modeling results can represent conditions in the field. From the results of the analysis and simulation, it was obtained to equalize the cycle time of each intersection to 105 seconds by adjusting the green time value according to the load of the vehicle coming on each strain. The queue value obtained became optimal and the delay was reduced in the range of 0.75 - 22.53 seconds with a decrease value of 4.97% - 40.71%.
