T The increase in the number of vehicles which is quite large in this type of passenger car, especially in Jakarta, is not comparable to the increase in road capacity which causes traffic problems and has an impact on the surrounding environment. Therefore, road infrastructure needs to be improved, especially at intersections. Therefore, further research needs to be done to see how much influence the alternative of increasing intersections has in supporting the implementation of Eco-Driving. This study aims to identify the causes of traffic congestion and the behavior of motorists at intersection locations. Analyzing the performance of existing intersections as well as the results of road widening and/or flyovers to improve intersection performance and traffic conditions using Vissim PTV software. The result of identification of existing traffic on PTV Vissim is high vehicle volume. The result of PTV Vissim on the existing traffic conditions is that the service level of the existing intersection is at service level F. The solution at the Pengumben Post Junction is alternative 3 with a delay of 23.81 seconds / vehicle and the Medika Permata Hijau Hospital Interchange is alternative 2 with a delay of 12.67 det/kend. Based on the regression test obtained Y = 0.364 – 0.003X1 + 0.006X2 (X1 = length of queue; X2 = delay) which simultaneously the performance variable is related to the Eco-Driving variable. For fuel savings at the Simpang Pos Pengumben as much as 234.34 liters at peak hours total volume and at Medika Permata Hijau Interchange as much as 72.76 liters at peak hours total volume.
