ABSTRACT

Application of signalling at junction can make the delay time longer. The delay time at the junction will be related to the amoun^Zt of fuel consumption of vehicles. In this study, research will be conducted on delays with fuel consumption at the Degolan Junction. The purpose of this study was to determine the comparison of vehicle fuel consumption between the unsignalized junction and signalized junction. Junction performance analysis was carried out based on IHCM 1997. The fuel consumption analysis is carried out based on the length of the delay using the equation from LAPI-ITB. Furthermore, data analysis was carried out using linear regression analysis. Based on the results of the analysis, it was found that the average fuel consumption at the Degolan Junction when the junction conditions were not signalled was 9.553 liters/junction. Meanwhile, when signalling is applied to the Degolan junction with details, alternative 1 produces an average fuel consumption of 40,144 liters/ junction, alternative 2 produces an average fuel consumption of 40,646 liters/ junction, and alternative 3 produces an average fuel consumption of 39,937 liters/junction. The results of the analysis show that the performance of the junction in the form of delay has an influence on fuel consumption.
