Engineering and Traffic Management Study for the Operation of the Makassar Elevated Toll Road

The development of the area, especially the city of Makassar, has a significant impact on traffic activities which causes traffic problems. For this reason, this study aims to see how much influence the operation of the Makassar elevated toll road has on the surrounding traffic, especially at the intersection of Jln. A.P. Pettarani - Jln. Boulevard and Jln A.P. Pettarani - Jln. Let. Jend. Hertasning. The data required in this study include surveys of traffic volume, vehicle speed, queue length, and geometric road data conducted on Tuesdays, Wednesdays, Saturdays, and Sundays, with survey periods starting at 07.00 – 09.00, 12.00 – 14.00, and 16.00 – 18.00. Engineering studies in the form of traffic simulations using vision software. From the results of traffic simulations on Wednesday, there were three intersections with the most significant queue length occurring at 16.00-18.00, namely the Boulevard short of 273.85 meters on Wednesday and 222.71 meters on Saturday. The application of a traffic design with an alternative change in traffic signal time at the A.P. Pettarani-Boulevard interchange was reduced by 26.21 meters and 23.75 meters from the existing conditions on Wednesday and Saturday. And for the alternative application of changing the direction of traffic movement at the A.P. Pettarani – Let. Jend. Hertasning, the decrease in the length of vehicle queues on Boulevard short was 21.31 meters and 17.56 from the existing conditions on Wednesday and Saturday.
